COMPUTER
CLASSIFICATIONS OF COMPUTER ACCORDING TO SIZE
EMBEDDED SYSTEMS
Computer-based systems which are standalone electronic hardware designed to perform dedicated computing tasks
PERSONAL COMPUTERS
Are the most common and widely used computers today which you can see in homes, schools, and in most business. There are two types of microcomputers - the desktop computer and the notebook computer
SERVERS
Used to provide resources, services, and functionality to client computers in a server-client network model
MAINFRAME COMPUTERS
Are less powerful than supercomputers but are capable of great processing speed, multi-tasking capability, and high data storage
SUPERCOMPUTER
These high capacity computers that run continuously are being used by very large organizations, mostly big corporations and government institutions
MID-RANGE
They may be used fr certain assembly line operations or manufacturing stages in big Companies. The size of mid rnge computers may be as big as a washing machine. Maybe a stand-alone system for specialized applications including network servers.
ELEMENTS OF THE COMPUTER SYSTEM
CONNECTIVITY
Aside from the five information system technology components, another important element of a computer is CONNECTIVITY. Connectivity allows the computer to acess and share data and information that are available somewhere else.
DATA

COMMUNICATION DEVICES
Are components that connect the computer to the internet and other external devices. Example: Modem, network card, wifi crd, and bluetooth
Central Processing Unit (CPU)
Is the electronic circuitry inside the CPU case where the operations of sat and information are controlled and where programs are executed. Also included inside the CPU case are the motherboard, microprocessor power supply ram, CD drive, hard drive, and graphics/video card.
Input Units
Concert data and instructions into electronic form input into the computer
Output units
Convert electronic data produced by the computer system and display them in a form that the user can understand
