1. Describe the four basic types of microcomputers and microcomputers system units.
1- Pepole : People are end users who use computers to make them-selves more
2- Procedures: The rules or guidelines for people to follow when using software,
hardware, and data are procedures
These procedures are typically documented in manuals written by computers
3- Software: A program consists of the step-by-step instructions that tell the
computers how to do its.Software is another name of program or programs.The
purpose of software is to converts data (unprocessed facts ) into information
(processed facts).
4- Hardware: The equipment that processes the data to create information is called
Hardware. In includes the keyboard, mouse, monitor, system unit and other
devices. Hardware is controlled by software.The equipment that processes the
data to create information is called Hardware.In includes the keyboard, mouse,
monitor, system unit and other devices.Hardware is controlled by software.
2. Describe system boards including sockets, chips, carrier packages, slots, and bus
1-Sockets: Connection point for chips.
2-Chips: Tiny circuit boards etched onto squares of silicon
Silicon chip, semiconductor, or integrated circuit
Mounted on carrier packages.
3-Slots: Provide a connection point for specialized cards or circuit boards.
4-Bus lines: Provide pathways that support communication among the various
electronic components.
