Summary Computers are used all over the world and in all types of
environments including: government, medical, education, manufacturing, legal and leisure.
There are many different types of computers available including: Mainframes, Servers, Desktop PCs, Workstations, Laptops and Hand-held portable devices.
Data is represented by binary digits (bits) organized into bytes (B), kilobytes (kB ), megabytes (MB), gigabytes (GB), and terabytes (TB). Data transfer rates are measured by bits per second. Computer screen resolution is measured in pixels. Analog frequencies, wireless transmissions and radio frequencies are measured in Hertz.
Things to consider when purchasing a computer: Motherboard, CPU, RAM, Adapter Cards, Storage, Peripherals, UPS, Surge Suppressors
Computers are a collection of very complex components and peripherals. Safety procedures must be followed when working inside a computer, both to protect the equipment and prevent harm to the technician.
