Microcomputer The kind of computer that you and I own.

First computers whose CPU was on a single chip.

Many configurations: PC (personal computer)

Desktop

Notebook or laptop

Tablet computer

Tablet

Sub-notebook

Mainframe Computers

Typically large systems with large amounts of storage

Normally kept in rooms with special air conditioning

Designed to process large amounts of data.

Typically used by multiple users.

They require specially trained individuals to run them called computer operators.

Minicomputer Typically the size of a file cabinet or small

desk.

Multiuser systems.

Usually run by computer operators

Supercomputers Typically contain very powerful processors

and large amounts of memory.

Perform complex numerical computations to solve scientific and military problems

Servers Primary task of storing and retrieving large

quantities of data often of a specific type.

Database server

File server

Workstation The term has two meanings.

Sometimes used to mean standard desktop PC used by a worker in an office.

The term workstation technically refers to computers that run a variant of UNIX and are designed to be used by only one person. They typically contain high performance hardware. Often used in medical research, digital imaging and engineering. Even though macintosh computers might

technically satisfy these conditions, they are not usually workstations.

Embedded computer systems

General CPUs that run only one program

Typically found in automobiles, microwave ovens, DVD players, etc.

Probably accounts for at least 90% of all CPUs in use today.

Portable Data Entry Terminals

Handheld devices used to record data
