Memory Stick Speeds Explained

In a few short years since the launch of the first 4Mb flash memory card, the number of flash memory cards, aka SD Cards, available for digital cameras and other devices has exploded with a number of different formats and speeds of memory card. It’s no wonder the average person is totally baffled by this plethora of memory cards.

Not only are there different shapes (the format) and sizes of memory sticks such as Secure Digital (SD) Compact Flash, Memory Stick, etc, but also different speed ratings.

Memory card speed is the card’s performance with regard to how quickly data can be transferred to or from it. The card speed is often stated in ‘Times’ ratings i.e. 12X, 40X etc (just as the speed of recordable CD’s and DVD’s is measured), and sometimes more specifically in megabytes per second (Mb/s). By today’s measure, sub 30X represents a standard speed, 30X to 60X is mid-high speed and over 66X is high speed. The chart below shows the relationship between the two figures.

8X = 1.2 Mb/sec
12X = 1.8 Mb/sec (Also known as Class 2 for SD Cards)
20X = 3.0 Mb/sec
25X = 3.8 Mb/sec (Also known as Class 4 for SD Cards)
30X = 4.5 Mb/sec
40X = 6.0 Mb/sec (Also known as Class 6 for SD Cards)
60X = 9.0 Mb/sec
66X = 10.0 Mb/sec (Also known as Class 10 for SD Cards)
80X = 12.0 Mb/sec
90X = 15.0 Mb/sec
133X = 20.0 Mb/sec

Why do we need different or higher speeds cards?
This is mainly due to the advancement of our digital devices, especially digital cameras, camcorders and music devices. As manufacturers develop higher and higher spec devices (i.e. higher resolution cameras and more intense multi-media functions), they are creating increasingly larger amounts information to store pictures, movies, music and so on. This in turn takes longer to record onto the memory card. For example if you have ever used a high megapixel camera with a standard speed card you may have noticed the time lag between pressing the shutter button and being able to take the next picture. This lag or delay, in most cases, is caused by a slow write speed. Similarly, copying your photos to your PC could take time too and is caused by a slow read speed.
So who really needs high-speed memory cards?
Professional photographers and enthusiasts using professional grade cameras such as digital SLR’s should use high-speed memory cards of at least 40X speed. If you own a camera with a megapixel rate above ten million pixels, you will certainly benefit from a card with a higher speed rating. If you’re like most of us using a compact camera under ten million pixels, you’ll get great performance from standard cards with 25X or more.

Those using digital camcorders and devices recording MP3 music or video will also benefit from higher speed cards. It used to be where very few people would actually benefit from very high-speed cards. Typically only professionals who used expensive, specialized products benefited, but it’s fast becoming a requirement on many of the latest PDA’s, Cameras, phones and other mobile devices to make use of the extra speed made available by high speed cards.

People using high speed memory cards with equipment that has been on the market a while may not notice any difference in performance, but this has more to do with the limitations of the device than the flash card itself. This is because not only does your memory card have a maximum speed rating, but your camera or mobile phone will also have its own speed rating. When these products are combined, they’ll work at the “slowest common denominator” e.g. if you use a 12X flash card in a camera with a designed for a maximum of 8X speed, you’ll be transferring data at the slower 8X speed.

You should always check the capacity of your device before splurging on mega fast cards, but determining the speed compatibility of your device can be tricky. Most manuals just don’t tell you what speed of flash card you should use, now that would be far too easy, but they do tell you to buy their brand, which isn’t much help! So a general rule of thumb, if your camera is less than three megapixels the speed rating of the flash card doesn’t matter much. Most modern cameras have the ability to support far higher speeds than the cards available to purchase today, therefore, if speed is of importance, go for a faster card. Most mobile phones are fine with standard speed cards although some newer models will benefit from higher speed cards but not generally over 60X speeds. Hope this info helps you pick your next SD Card wisely.

Why you Need to Keep your Computer Clean

If your computer is used a lot and kept on for hours at a time, it’s a good idea to clean it every now and again. Dirty computers often do not run as fast as they are advertised to and have a lower life expectancy than ones that re well kept and cleaned often. One of the main problems keeping your computer form running at its optimal speed is dust. Dust inhibits the fans form properly cooling the computer parts and often leads to hardware failure. Dust is also conductive, so in theory it could short circuit your computer and cause it to not work any more.

If you have a desktop computer, then the main place dust accumulates is around the CPU unit and fan areas. To prevent your processor from overheating, there is a fan connected to a heatsink which sits on top of the processor to disperse the heat. This fan blows air down in to the heat sink to cool it down as the heat is passed up from the CPU into the heatsink. Because the fan is constantly blowing in air, it also blows the dust particles from the air in to the heat sink. Over time this can clog up the computer’s heat sink, reducing its effectiveness. Because of the dust, the fans ionside of the computer may have to blow faster to maintain the same temperature on the actual processor. This makes your computer louder and more costly to run. Normally, you can see if the fan is clogged up simply by opening your computer up and looking at it. If your fan’s heat sink is really clogged up with dust, it is a good idea to give it a clean. When dealing with the inside of your computer, or anything electrical for that matter, ensure the power is turned off and your computer is unplugged first.

The best way to clean out the insides of your computer is by using a can of compressed air that includes a special nozzle. This special nozzle is a long plastic straw that protrudes from the sprayer. This tool allows you to reach into very small spaces and clean without having to take apart your computer.  You can buy this from any electronics retailer. When spraying the compressed air on to your computer, make sure you don’t spray it for to long as condensation may form some drops of water. When you spray compressed air, the air is very cold. this cools down the parts of the computer and if you spray the air on one place too long, condensation could form. As we all know water plus electronics equals bad results. After blowing away any dust from your computer’s heatsinks, give it a gentle wipe over with an anti-static cloth for good measure. You can also use the compressed air to clean your power unit and keyboard.

Cleaning the inside of your computer doesn’t take long providing you have the correct equipment, and once it is done, you notice an immediate improvement in your computers performance. The fan won’t need to blow as hard, so your computer will be quieter. And thanks to the processor running at a cooler temperature, your whole computer should generally run faster. I try to clean my computer every 4 or 5 months to keep it running efficiently. Doing small things such as cleaning your computer could have lasting positive effects.

All About Backups and Keeping Your Data Safe

There has been an increasing amount of emphasis in recent times on the subject of keeping the information on your computer safe. The terms Back-Up, Archive, Data Storage and Security being mentioned frequently, but what is all about?

In simple terms, people are increasingly holding more and more information on their computers, be it photos, personal data and finance, business data, accounts, contacts, addresses and much more.

What everyone needs to understand is that the information held on your computer is a very vulnerable entity and can be very easily and completely lost, either by component failure, malicious acts or theft. If loss of the information you keep on your computer would cause you distress, then you need to take steps to ensure it is kept safe and that you would be able to continue even if your computer was stolen.

The only definite way of safeguarding against the many different kinds of threats is to have a copy of the valuable information and keep it away from the computer, this is commonly referred to as back-up. In case of loss, the information can then be restored to a computer from the safe back-up copy. A back up consists of an exact copy of this important data, kept on a separate storage medium such as a CD / DVD or an external tape or hard disk drive.

Naturally, a back-up is only as good as the last time that you actually made a back-up copy, so it is common practice to create a new back-up frequently and overwrite the old copy. How frequently you do this depends on how often your valuable information changes, the more changes, the more frequent the back-up. A back-up can be performed manually by simply copying the data you wish to back-up to your chosen media, or the process can be automated by using specialist back-up software programmes. Back-up software allows you to select the data that needs to be backed-up, when to make the back-up and where to copy the backed-up data to, this set up can then be memorised by the back-up software. Backing-up your data then becomes a relatively quick and simple process.

Many confuse back-up with “archiving”. Archiving is where you transfer data, which is important enough to keep, but no longer required (e.g. old photos, old accounts) to an external, safe storage medium for future reference. The archived data is then removed from the computers main hard drive to free-up space.

Whether backing-up or archiving, there is a choice of media you can record your copy on to:

Recordable CD or DVD
If you have a CD or DVD recordable drive, this is a better longer-term solution with more space. The downside is that the recording process can be a pain as you cannot just drag and drop and that you need CD’s or DVD’s to record on.

This type of backup can be cumbersome, time consuming and sometimes frustrating, depending on the software and the quality of disks used.

When using this method of backup, remember to check the disk you have transferred your data to, to make sure your computer can read the disc ok in future.

USB Pen Drives
Also known by various other names USB Pen Drives are an excellent low cost solution for smaller back-up purposes being easy to use and they are also great for transferring data from one computer to another.

External USB Hard Drives
For most users the best storage solution for back-up and archiving purposes is the USB external hard drive, being reliable, easy to install (just plug in to your USB port) and easy to use (just drag and drop your files to be backed-up). USB External Hard Drives are available in pocket or desktop sizes and storage capacities from a few Gb to 250Gb + offering a huge amount of recording space. Being a plug in device they can be easily disconnected and kept separate from your computer and out of harm’s way. Some external USB Hard Drives like Iomega come packaged with back-up software too.

Computer Slow? Fix It Yourself!

Why does it seem like every time you get a new computer it operates at lightning fast speeds for only a few months before becoming slow and laborious over its tasks? Is this just something that we have to live with or can we do something to keep our computers running at optimum speeds?

The truth is that computers do not get slower as they age. A slow computer is a sign that something is literally holding your PC back and affecting its performance. And the good news is that you can do something about it.

There are many things that can affect your computer’s performance, from low memory to a fragmented hard drive and everything in between. The small errors or resource-heavy programs that can affect your computer’s performance are usually of your own doing. Each time we download a program or delete a program, we affect the way our computer operates. This change in operation can leave holes in our PCs operating procedures or may even leave behind programs that can affect our computer’s performance.

Here are just a few things that could be making your computer slow:

· Running Background Programs – These programs are software applications that are running behind the scenes even when they are not in use. You may not even know that they are running, but they can zap precious memory and slow down your other tasks considerably. To see if you have programs running in the background, press Ctrl + Alt + Delete at the same time. The box that pops up will show you all applications that are running.

· Full Hard Drive – If your hard drive is too full of data, it will not have enough space to perform chores. Your hard drive should have at lease 2GB to 3GB in free space.

· Fragmented Hard Drive – When you download and delete programs, you create holes in your hard drive. These holes mean that your PC has to search for the files it needs over greater distance and not necessarily in the order that it needs them.

· Left Over Parts – When you install and uninstall Windows programs, they leave behind parts or applications that can slow down your computer. You may even unknowingly delete a file needed for other software applications. (Note: Spyware and viruses can also slow down your PC’s performance, but for the purpose of this article we are assuming that the problem lies in application errors.)

Make Your PC Run Like New

While it’s not rocket science, making your computer lightning fast once again will take a little work from you. Sometimes, this is as easy as running your Windows System Tools program. You can find these programs by clicking “start,” “all programs,” “accessories,” and “system tools.” Here you will find several system optimizers to help you free up your disk space, defragment your PC, and detect and repair disk errors.

In addition to tools already installed on your PC, you can opt to download additional programs to optimize your computer’s performance. These optimizers can be either  purchased as a set or downloaded for free individually off the web. These optimizers, along with other software programs can help you get the best out of your computer. Here are just a few of the extra optimization programs that you may want for your PC:

· Memory Optimizer – When you are using your computer, it takes several programs and application to handle everything that you are doing. Each of these programs uses memory. When memory is short, computer response time is slow. Memory Optimizer helps to make the allotment of memory to each program more efficient. This can help you eliminate slow PC execution time, Windows hang up or crashing, loss of data and unwanted shutdowns.

· Registry Deffrager and Optimizer – As mentioned before, a registry with holes results in slow response times as your PC searches for the data it needs. This program improves the system response time and saves memory by creating a smaller registry.

· Windows Optimizer – We all use our computers differently. Some use their computer as a media and entertainment centerpiece while others use their PC for data storage and business purposes. Windows Optimizer allows you to tweak program settings so that they will perform in line with your needs.

Granted, a slow computer is a nuisance and it may leave you wanting to go out and purchase a new model. But before you give up on your current model, make sure that you have optimized it first. You may be surprised by how much life is still in your PC.

Choosing the Right Motherboard

The motherboard is the heart of every computer. It is that big flat board inside the computer that everything is connected to. It performs the role of directing information and connecting components. A motherboard is often the central part of the computer design process. Therefore, choosing a motherboard that’s right for you is essential to your computer build.

Choosing the right motherboard does not have to be a problem, even though there is a lot to consider. We will start off with the larger parts and move onto the things that are less essential.

Firstly is the socket type. The socket is where the processor (CPU) connects to the motherboard. There is no compatibility between sockets, so you have to get a processor and motherboard with the exact same socket size. The socket connection needs to match the connection of the processor you have or the one you intend to buy for the computer.
Most older Intel Pentium 4s utilize socket 478. Newer computers use socket 775 and 1151. AMD chips utilized socket A for a long time, but now the AMD Athlon 64 series and Semprons use socket 939. Be sure to double check the socket size before ordering your products! It saves a lot of time and frustration later if you do your research before you order the parts.

Your choice of CPU will have a lot to do with your needs, but choosing one with an up to date socket type will ensure slightly longer motherboard life as you can upgrade the chip for a while.

DDR3 is the RAM of choice for most systems, but some newer systems, like the ones with the new core I7-6700K use DDR4. These two kinds are not interchangable and have a different number of pins. DDR2,  DDR3 and DDR4 RAM chips come in different speed ratings measured in MHz. Make sure your motherboard supports the speed in MHz that yuo want to buy your memory in. This can be found in touring a prospective motherboard’s manual online.

Finally, we must look at the expansion slots. If you want to add a graphics card to your system, make sure you have a PCI-E x16 slot on the motherboard. That is the long slot with a clip on the end of it. This will allow you to expand your system in the future.

Choosing a motherboard should be proactive; you should think about how you want to upgrade your system in the future when you purchase a motherboard. Motherboards aren;t extremely cheap and if you can reuse the same motherboard in a future build or upgrade it currently, you can save a lot of money in the long run.

A motherboard must be chosen carefully, to both match all the other components and fit in the case you choose. A little bit of research before you buy will save a lot of hassle later on.

Fix A Scratched CD

Ever had some archived data on a CD and get errors? That precious DVD with family photos have a scratch in it? Trust me. We have all been there. Here is how to fix it.

In this article I will be showing you four little known tips to fix scratched CD or DVD and recover the data within. Every user has had trouble with a scratched CD or DVD. The theory goes like this – A CD/DVD reader or player uses a laser beam to read the data on the disk. This laser beam crosses the protective plastic layer and reads the real recording metal layer. If the protective plastic layer is scratched, the laser will be unable to pass resulting in non-readable disc. In the case of data CDs the CD/DVD reader is unable to read the CD/DVD properly resulting in reading errors while in case of audio/video discs, the CD player skips when we play it.

If somehow we manage to re-smooth this protective layer then the laser will reach the data and read it, now there are many ways we can achieve this using common household item’s as discussed below:

1). Toothpaste – Yup! Toothpaste is our very first scratched CD/DVD fixer, you can use any non-gel based toothpaste for this, just put a very small amount of it on the scratched area and polish it gently using a cotton swab, sometimes the paste may cause new minor scratches but they are just superficial. Now just wash the cd using water.

2). If the above trick does not work try some metal polish like Brasso gently wiping with a soft cotton ball followed by application of Vaseline.

3). Baking Soda – make a small quantity of baking soda paste and apply using a soft cotton cloth buffing the bad scratch. Clean the baking soda before using the disc.

4). You can also try using some oil as a polishing agent this also works many times.

There are many daily use products that can be used to get the cd working just keep on experimenting, please note that you must take special care while using the above tips, be sure to try and preserve the rest of the cd that is not damaged just in case the cleaning process scratches it some more.

So that is some tips on how you can make a CD or DVD reusable after it has been scratched!

How to Prevent Computer Power Failures

Category : Hardware , Projects , Tech Tips

Power loss is bound to happen sooner or later. Whether it be a thunderstorm, power outage, or brown out, all of these power abnormalities can cause data loss and corruption. And if you are anyone who knows anything about computers, you know data corruption is bad. I advise that you should adopt anti-melt down measures for PCs, laptops, and servers.  I have experienced data loss because of high temperature brown outs and thunderstorms causing power outages, and the results are not pretty. I wrote this article to help others prevent data loss like that which happened to me.

First off, There are some rules that should be followed when arranging the computers in a home or office to prevent data corruption. The computers should be placed in cool and dry areas to prevent overheating. It is also highly recommended that not too many computers to be running off of one power supply. This will overload the circuit on the circuit breaker and increases the chances of a power failure or brown out. It has become almost a necessity to have a surge protector installed between the power socket and the computer’s power cable. These protection devices should be checked regularly to avoid premature failure. Computers should not share power with air conditioners and fans but dedicated circuits should be used.

These are general rules that should be followed in order to protect your computers, but there are some tips that I am offering for special cases such as thunderstorm and blackouts. During thunderstorms PCs should be turned off and disconnected. Another good measure in a bad lightning storm is to remove the uplink cable from the modem jack. This cuts off internet, but if a lightning strike were to occur, your modem would be fried on the spot.  The best solution to avoid losing data during a blackout or brownout is to invest in some form of uninterruptible power supply, also known as UPS, which regulates the voltage to the power supply and features backup batteries to keep servers running during power outages. This is highly recommended especially for the offices that have network servers.

In conclusion, these are just some of the ways that you can prevent data loss. You can take all of my advice, some of my advice, or none. This article is to prevent what is bound to happen sooner or later: Power failure.

How to Pick Parts When Building A New Computer

Picking the parts for your computer is one of the most important things in building a computer, because you can’t assemble a computer without the parts! Picking parts for computers has become much easier than before, because form factors have been standardized; however, you still need to make sure everything will fit together properly. The first thing to think about when choosing the components for your computer is what you are going to be using your computer for. If you are creating a computer for just checking your eMail and using Microsoft Word, you are going to need different parts than a computer that you are going to be using for gaming.

CPU
The first thing you should pick out about your computer is what CPU you are going to use, because it determines what motherboard you are going to get, which determines what other components you get, et cetera. There are two main CPU manufacturers, Intel and AMD. Both have their Pros and Cons, but they are pretty similar. I would suggest using Intel, because they make notable processors like the Core i7 or Xeon processors. If you are spending below $500, I would suggest a budget processor like a core i3 or i5, Between $500 and $1000, midrange and $1000 and above I would suggest a high end processor, like any higher clocked i7.

Motherboard
Choosing the right motherboard is vital to building your computer. First, make sure you find a motherboard that has the right socket type for your CPU. Then, check the different features of the motherboards you are looking at. If you aren’t going to buy a video or sound card, make sure your motherboard has onboard video and/or sound. Other things to check for on your motherboard are the hard drive interface, graphics card interface, expansion slots, the memory size and speed. Also, check for the chipset. There are too many to talk about, but generally Intel and nVidia chipsets are better than the other ones. Now that you picked out your motherboard, you know what to look for in your other components.

RAM
Getting the right speed and amount of RAM is vital to the speed and stability of your system. If you are running Windows 7, you will probably need at least  2Gb of RAM. If you are going to be doing anything memory intensive, gaming, rendering or just want a faster computer, you should get 4Gb or more. I reccomend maxing out the amount of memory your motherboard can handle. To see this number, refer to the motherboard’s website or user manual. Make sure your motherboard has enough DIMMs and the right type of DIMMs for your RAM. Also, be sure to check the speed of the memory

Hard Drive
Now its time to pick your hard drive. There are few variables in picking a hard drive. The first, and most important is size, 250Gb is usually enough for most people unless, you are going to be storing alot of pictures and video. Also, make sure you get an HD with the right interface that fits your motherboard. Almost all motherboards have the SATA (Serial ATA) interface. Sata is a much faster hard drive interface and uses a thinner cable than older IDE drives. Having a thinner cable helps with airflow in your case. There is even SATAIII now, which allows for transfer speeds for up to 6 Gb a second. Also look at rotation speed, almost all desktop HDs are 7200RPM and Cache, most are 16Mb, don’t buy a HD below those standards. If you want to spend some money, you can get 2 smaller HDs and run them in RAID which increases performance. RAID is connecting a series of drives to work as one with greater write and read speeds. This is because different parts of data are stored in different physicasl drives rather than a different location in one drive.

Video Cards
If you are going to be doing any gaming, be sure to buy a video card, if youre not, onboard video is fine. The first thing to check for is the interface, most are PCI-E. I personally like nVidia cards better. If you are going to be doing graphic intensive games or video rendering, I would suggest at least a GTS 250. If you have alot to spend, go with a GTX 980.

Optical/Floppy drives
Another thing you are going to need sometine is a DVD drive, these are IDE or SATA. The optical drive is almost defunct nowadays, but it is a great thing to have when you need to install the operating system from a DVD or want to watch a movie or play a CD. This should not cost you much; it should be only $20.

Power Supply
Make sure you have a sufficient power supply!! If you have a high end computer, you should get a 650W or greater PSU. Otherwise, 350W should be fine for most people. If you need any help figuring out what power supply you need, just do a google search for “Power supply calculator” and that should answer your question.

 

Case

Most cases are ATX, but make sure it is the same type as your motherboard (ATX, MicroATX, BTX, etc…). This is crucial to connect the front panel and fan connectors found inside of the case to the motherboard. Also, look out for package deals where a case is bundled with a power supply. Even though these power supplies are not as good as a main branded one, they do the job.

 

So that’s all of the parts you need to make your computer! A final word of warning: Be sure to make sure all your components are compatible! You don’t want to accidentally fry something or void the warranty on your components. Please do as much research as you can before ordering parts. It will make your life a whole lot easier once you get the parts and are ready to assemble your computer.

Laser Printers

Like with many other things in the world of printing, laser printers have come a long way in the past few years. They have gone from being found almost exclusively in offices to being offered at $100 for a home user. Although they are better for a lot of people, some have a hard time imagining themselves buying a laser printer for their home. A lot of people have the idea that laser printers are just the big clunky machines in their offices where the toner cartridges cost a fortune. However, if you are someone who prints out a large amount of documents and is tired of always having to buy new black inkjet cartridges, laser printers can be the solution. Once you get past the initial sticker shock of buying laser toner cartridges, you will realize the numbers for an entry level laser printer versus an inkjet printer look something like this:

Typical toner cartridge – $20-$60
Page yield – 2,000-3,000 pages
Average cost per page – 2-2.5 cents per page

Typical inkjet cartridge – $20-$30
Page yield – 400-500 pages
Average cost per page – 4-6 cents per page

Although these are just averages and may not seem all that different, in general if you are printing documents, it will probably cost you twice as much to run an inkjet printer than a laser printer. It is better to think of things in the long term when it comes to laser printers, because only then will you truly appreciate their value. If you buy a laser printer and then a backup toner cartridge at the same time, by the time you will have finished that second cartridge, you would have gone through roughly 10 inkjet cartridges.

So if you aren’t into printing color, then you are probably better off going with a laser printer over a standard inkjet printer. You will appreciate the speed and low maintenance of a laser printer, while also saving money on printer ink in the long run.

What is a Pen Drive?

A Pen Drive is a removable storage device that plugs into a computer’s USB port. Small enough to carry on a key ring, Pen Drives are great for transferring photos, music, documents and any other data from one computer to another. Different manufacturers over the years have named their Pen Drives with many different names causing constant confusion.
As a result of this the Pen Drive can also be known as Pocket Drive, Thumb Drive, Jump Drive, USB Flash Drive, USB Flash Memory Drive, USB Key Drive, USB Memory Key and USB Memory Stick among many others!

Although none of these names are either correct or incorrect, one of the names cause a huge amount of confusion for people, this is when someone referring to a Pen Drive, uses the term “Memory Stick”. This is because “Memory Stick” is a Sony trademark and refers to a type of memory card used in Sony’s electronic devices, it is therefore a completely different product, which will not plug directly into your computer’s USB port!

Pen Drives were invented by IBM in 1988 as a replacement to Floppy Disks but were never patented by them, M-Systems who were later contracted in by IBM to manufacture Pen Drives actually own the patent. So think of a Pen Drive as a modern day floppy disk. The main difference being that a floppy disk contains moving parts which can make the data stored on it vulnerable, a Pen Drive is solid state meaning there are no moving parts inside, making it resilient to dust and everyday magnetic fields and so a safer storage option. Also Pen Drives can hold much, much more data than the floppy disk.

Once connected to a computer’s USB port the Pen Drive appears in Windows as a “Removable Drive” alongside your C Drive, CD ROM Drive etc. You can simply drag and drop photos, music, documents and any other type of data on to the “Removable Drive” just as would with any other folder on your computer (no complex recording like CD or DVD is required). The Pen Drive can then be removed (see Safe Removal of Pen Drive below) from the computer and plugged into another computer’s USB port giving you access to the information you copied to the Pen Drive.

The compact size, robust nature and low cost of the Pen Drive has made it a big hit and an indispensible tool for many. It is ideal for transporting personal, or work data from one location to another, i.e. from home to school or office, or for carrying around data that someone may want to access in a variety of places. An insurance company in the US loads customer bio data and policy details on a tiny Pen Drive and advises policy holders to wear it with a neck strap in case of emergencies, another company is doing the same with policy holders who go Sking. Another company videos their conference and records it onto the Pen Drive so that the delegates can refer to it in future. Pen Drives can also be used to back up your important documents.
