What is Computer Hardware?
Hardware is the physical parts of your computer (inside and out) that you see and use everyday. The monitor, keyboard, printer, scanner, hard drive are all common pieces of hardware. Each part is essential for your computer to run properly. Unfortunately, hardware becomes obsolete very quickly. Today's hardware also doesn't last as long as it used to either. One of the first computers is still running well for the kids to play their games, yet some hardware in the newer computers has had to be replaced a couple of times due to break downs and failures. On the up side, hardware is much cheaper to purchase. Hardware is like everything else, it all breaks down! It is not the end of the world if something does break, just make sure you have your warranty in a safe place and you will be back up and running with you new hardware in no time.
Your Hard Drive: – Stores all your software, letters, games, information permanently on your computer.
Your Floppy Drive/CD ROM: – The means of installing software to your computer.
Your Motherboard/Main board: – The main part of your computer that controls all the other hardware parts.
Your Central Processing Unit (CPU): – The brains of your machine. Dictates how fast you can do your tasks.
Your Modem: – Comes both internally and externally and is the means to connect you to the World Wide Web and e-mail.
Your Printer: – The hardware you use for making hard copies of your master pieces.
Your Keyboard: – A way of telling your computer what and how to do your required tasks.
Ram: – (Random Access Memory) Small pieces of hardware that can be upgraded to help increase speed and performance. (commonly known as adding a stick of ram.) Usually comes in 32meg, 64meg, 128meg, 256meg sizes.
Computer Case: – This is the box that holds all your pieces of hardware. It contains a power supply usually about 250 - 300 watts. You will need a larger case if you intend to add a cd burner (CDR/RW) or a DVD player etc.
Scanner: – This is a great tool for copying pictures, photos or information. Scanners usually come in flat bed form which means you can copy large photos by inserting them into the scanner. The appropriate software makes your scanner work correctly.
Video card: – This card is inserted into your computer to make the graphics more pleasurable to the eye. It also helps with the overall speed of your machine. Buying at least a 32meg video card is more recommendable and this will improve your systems performance dramatically.
Network Card: – A network card connects two or more computers together. This enables both computers to share printers, internet access, files and games. A network is fairly easy to setup. You will need a network card, hub and some cables. They sell network kits for reasonable price at most computer shops.
CD Burner: – A great piece of hardware for backing up your data. Due to large amounts of information being stored, the good old floppy disk is just not large enough. For example, the video card drivers are 14meg in size so one would need a lot of floppy disk to back it up.
Mouse: – A seldom thought of very important piece of hardware. Mice come in two forms Roller Ball and Optical. Roller Ball mice are relatively cheap but require a lot of maintenance, whereas the optical ones work by a laser and require minimal maintenance.
