Different hard drives of a computer
Cool article on the different types of harddrives at pctips
What is a hard drive? Often people think a hard drive is their entire computer system as they see it, and others think that it is something hard or solid in the computer. It actually is a storage device inside your computer, and yes, it is hard. . This is hiding inside your computer and is where all your data is stored when you save it. You may never see your hard drive unless you happen to open up your computer to fix a problem. A hard drive is merely one of the many components that contribute to your computer system as a whole.
What is the difference between Hard disk and Hard drive?
It can be confusing when someone is talking about a hard drive and you call “it” a hard disk or hard disk drive. You think to yourself “what are they talking about?” Well this is crazy, but they are talking about the same thing. A hard disk and a hard drive have been made up over the years. Originally the main storage device was called a hard disk and we had floppy disk drives. Eventually the words got mixed up and blended.. That’s my theory anyway.
3.5″ Desktop Hard disk drive:
The picture below shows a 40 gigabyte (the size or capacity) hard drive, 7200RPM (the speed or revs per minute). The 3.5″ hard drive is pictured on the left. We used to only have one option when buying a hard drive, however now there are three or more types to choose from. See more pictures of hard drives .
2.5″ Laptop Hard disk drive:
A laptop hard disk drive is considerably smaller than a normal desktop hard drive and also cost more. If you wanted to buy a 500gb laptop hard drive it would be very expensive, whereas a 500gb desktop hard drive is around $100. See more laptop hard drives .
Cd rom or DVD Drive:
This is where you put a cd rom or a DVD disc in. It could be a drive that can also read and write on cds or DVD disks. Plain old Cd roms are nearly obsolete as everyone now wants a DVD burner.. With dvd rom drives you can backup your dvd’s onto a DVD writeable disc. There is no point buying a cd rom when dvd rom drives are the same price and have more features.
Floppy disk drive:
This is the smaller drive that takes those little plastic square shaped disks. They are rarely used now as they are no longer needed for a boot disk if you have a cd rom or DVD burner. In fact most new computers are sold without a floppy disk drive as they are obselette.
External Hard drive:
An external hard drive can come in two sizes like the desktop hard drive and the laptop hard drive. After all an external hard drive is just a case housing one of these hard drives. So if you have a 2.5″ external hard drive , this means it contains a laptop hard drive.
Now days we every second household owns an external hard drive. They are used to store files on safely away from the computer you are working on. For example, you can save your photos onto an external hard drive and if your computer crashes they will still be safe because they are not stored on your computer. There is no excuse if you do not own one of these fantastic storage devices as you can buy a 1 TB external hard drive for well under $100. That size hard drive can hold thousands of movie, songs, and more… It will store everything.

How to Increase Wifi Distance in your Home
You can extend the wifi range of your wireless network if you experiment with various techniques. Because there are so many variables involved with consumer WiFi, you will need to experiment to determine what works best with your scenario, the structure of your home and the equipment you use. All of those things play a roll in the range of your network as well as its reliability. While we always try to find the cheapest solution, you may find additional equipment is necessary to achieve your wireless goals.
Tips For Increasing The WiFi Distance
Centralize your router. This is one of the easiest things you can do to gain maximum coverage area for your WiFi network. Normal WiFi antennas emit signal outward in all directions. If your router is situated near a wall in the corner of the house, much of the signal is being absorbed by the wall behind it and leaking outside. If you place the router in the center of the living area, you will extend the range to all usable areas of your house.
Purchase a high gain antenna. If your router has a detachable antenna, you should be able to add a high gain antenna. These types of antennas are more directional than your standard antenna and allow you to focus your WiFi signal toward an access point or your computer. You can also make these, which are often referred to as “cantennas,” but you’ll probably have better results if you purchase one. High gain antennas are a great way to shoot the WiFi signal across a house or even a yard. But in order to achieve maximum range, you should have line of site to the target.
Add a WiFi Repeater. You can add a Wireless Access Point (WAP) to considerably extend the range of your wireless network. These are often referred to as “repeaters” or “extenders.” Depending on the size of your home or office, usually one repeater will be enough to cover the entire area. You will want to place the repeated as far as you can away from the router without losing more than twenty percent of the signal. The WAP will then reconstitute the signal pass it along to any devices within its range. Here is an example of a WiFi Extender Cisco-Linksys Wireless-G Range Expander WRE54G.
Change the wireless frequency in the router. If you do not get the results you want by moving the router, you can try changing the frequency the router uses to broadcast the signal. You only need to do this in the router itself, as the wireless devices should recognize the new signal automatically. All makes and models of routers have different menus, but all you need to do is login to your router through your web browser and look in the wireless settings. Experiment and see if changing the frequency helps.
Buy a new 802.11n router. The latest wireless standard is 802.11n. It uses Multiple-Input Multiple-Output channels and has nearly double the range of a wireless-g. Here is an example of a Wireless N router: Cisco-Linksys WRT160N Wireless-N Broadband Router
