Web cams can be very dangerous though, if they are in the computers. Reason being because they can get hacked. Printer/Scanner Printer is used to print of things from your computer. Some printers are wireless others are connected to your computer. A scanner is part of the printer, it scans a piece of paper then prints it out. CPU/Processor CPU stands for Central Processing Unit. Others also called it the processor. This has a very important role, the CPU is used to make your computer work. Its like our brains for example, we need our brain to be able to function. Same with a computer, it needs the CPU to be able to work. Motherboard The Motherboard is where everything gets held. Such as CPU, memory card, control video card etc. Power Supply The Power Supply is the makes the computer stay on, you have to plug it into the wall for the computer to work. Graphics Card A graphics card helps enhance games, by making them faster and better quality. Sound Card The sound card is what makes the sound work for your speakers. Hard Drive The hard drive is what stores all your documents and other things that you have saved to your computer. CD/DVD ROM Windows doesn't have a proper command line. Each application looks completely different. There is no way to save the system when crashes occur. Apple Apple designs, develops, and sells electronics. It is a major developing industry and their main competition is windows. Mac and PC's have been in a battle for many years. PC's were the go to computer because developers used to write the best app for windows first. Window has software that is more widely available. Macs are more expensive than PC's. You can get better customer support with a Mac. Application software PC's There are many different types of application software for PC's. Some of them include, Microsoft Windows, Excel, Publisher, Weebly, Prezi, and many more. Microsoft Word Microsoft word is a word processor. The recent versions of this application is Microsoft Office Word 2010 and Microsoft Office Word 2011. Word is commonly used as a format for sending text documents.

Word 2010 helps you organize and write documents more efficient. Also it has formatting effects (shadow, glow, reflection), editing tool, and many more. Networks There are many types of computer networks like Personal Area Network (PAN), Local Area Network (LAN), Metropolitan Area Network (MAN), Storage Area Network (SAN), and Wide Area Network (WAN). CD/DVD means when a CD or DVD is put into the computer it will read what is on that disk, and play it.Once the disk is taken out the computer will not store what was on there. The computer network that is designed for personal use is known as PAN. When you need a network to be in a small are you use LAN. CAN is a lager network than LAN, CAN is mainly used in campus of universities to make connections throughout the school. MAN has many applications, it is mostly used in banks.

A router is a device that forwards data packages between computer networks. There are more than one line connected to different networks. The router reads the information. Routers pass data (web pages, email) between home computers and the owner's cable or DSL modem. Wi-Fi is a very popular technology that allows an electronic device to use internet wirelessly.
