Computer Hardware

This section will talk about computer hardware from the ground up. It is intended for beginners who don't know what computer hardware components operate inside their computers. In this section, we will not only analyze and explain the component parts of a computer, but we will explain how you can buy a computer from component parts, and assemble it. We will guide you around the pitfalls of your computer purchase to the assembly and installation of your computer hardware and operating system. When you are done reading this section, most of the mystery about computer hardware should be clarified.

Terms

• bit - A logical data unit which has a possible value of 0 or 1.
• byte - A unit of data storage consisting of 8 bits.
• cycle - An electrical cycle is basically a sinewave form during which electrical voltage will cycle from its lowest negative value to its highest positive value and back again.
• computer hardware - Refers to the various electronic components that are required for you to use a computer along with the hardware components inside the computer case
• hertz - A unit of frequency describing the number of electrical cycles that occur in a second. One hertz is one cycle per second. Power is delivered to homes in the United States at 60Hz and in Europe at 50Hz.
• megabyte(Mb) - A unit of data storage consisting of about one million bytes. This is normally used to refer to the amount of system memory or floppy disk storage.
• megahertz(Mhz) - A unit of frequency. It is one million hertz. It describes the clock frequency the microprocessor runs at. The larger the number, generally the faster the microprocessor, but there are other factors that affect microprocessor speed.
• gigabyte(Gb) - A unit of data storage consisting of about 1000 megabytes. This is normally used to refer to the amount of capacity a hard drive has.
• RAM - Random Access Memory
