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.
