Classification of computers (- Minicomputers) (Microcomputers)

Classification of computers]
Computers that process analog data are called analog computers. (Analog data is continuous) 
The input data is not a number infect a physical quantity like temperature, pressure, speed, velocity.
Computers that accept analog input and provide analog output.
Deal with variables.
It is used for measuring physical quantities. 
Special purpose computers.

Computers that accepts digital input and provide
digital output.
The input data is represented by a number (Binary Number System).
These are used for the logical and arithmetic operations.
Measure digital quantities.
Microcomputers are more commonly known as personal computers. The term "PC" is applied to IBM-PCs or compatible computers.

Full-size desktop computers are the most common type of PC.

Notebook (laptop) computers are used by people who need the power of a desktop system, but also portability.

Handheld PCs (such as PDAs, IPADs) lack the power of a desktop or notebook PC, but offer features for users who need limited functions and small size.

Minicomputers are smaller than mainframes but larger than personal computers.

Also called midrange computers.

Powerful Minicomputers usually entertain input output need of hundred of user at a time.

Example HP 3000

Minicomputers may be used as network servers and Internet servers.

6. Microcomputers, or Personal Computers
•Microcomputers are more commonly known as
personal computers. The term "PC" is applied to
IBM-PCs or compatible computers.
•Full-size desktop computers are the most common
type of PC.
•Notebook (laptop) computers are used by people
who need the power of a desktop system, but also
portability.
•Handheld PCs (such as PDAs, IPADs) lack the
power of a desktop or notebook PC, but offer
features for users who need limited functions and
small size.

9. -Minicomputers
•Minicomputers are smaller than mainframes but
larger than personal computers.
•Also called midrange computers.
•Powerful Minicomputers usually entertain input
output need of hundred of user at a time.
•Example HP 3000
•Minicomputers may be used as network servers and
Internet servers.

12. Workstations
•Workstations are powerful single-user computers.
•Contains many functions of personal computers but
with the processing power of mini computers.
•Workstations are used for tasks that require a great
deal of number-crunching power, such as product
design and computer animation.
•Used by scientists, engineers and animators.

15. -Mainframe Computers
•Mainframe computers can support hundreds or
thousands of users, handling massive amounts of
input, output, and storage.
•Each user access the mainframe computer through a
device call terminal. There are two kind of terminals.
•Dumb Terminal
doesn’t have its own storage and processing
capability.
•Intelligent Terminal
It can perform some processing but doesn’t have
storage capacity.
•Mainframes are also used as e-commerce servers,
handling transactions over the Internet.

19. -Supercomputers
•Supercomputers are the most powerful computers.
They are used for problems requiring complex
calculations.
•Process huge amount of data, the fastest super can
perform more than 1 trillion calculation per second.
•Can house thousands of processors.
•Supercomputers are used for weather forecasting,
satellites data processing, nuclear fusion processes.

24. lesson Review
•List the five most common types of computer systems.
•Identify two unique features of supercomputers.
•Describe a typical use for mainframe computers
•Differentiate workstations from personal computers.
•Identify four types of personal computers.
