Supercomputers
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
Personal Digital Assistant (PDA)
Smartphone
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
Web server
Mail 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
