The following are parts of a computer except:

Computers have various types of _____ device for long-term data retention.

Used to provide data and instructions to the computer.

Often reffered to as the "brain" of the computer.

Displays or provide results to the user based on the computer's processing.

___is raw, unprocessed facts. It has the potential to become a useful information, but first it has to be manipulated and transformed.

___is processed data. It is a data tht has already been manipulated.

The following are the Four Basic Functions of Computer exept;

GIGO means... wrong data entered into the computer will result to wrong information produced.

It can process data quickly

It can perform operations tirelessly

It can store, recall and retrieve information

It can give accurate results depending on the instructions and commands given.

It can perform multi-tasks.

It needs human intervention.

The information or results generated are user dependent.

It has short lifespan

It cannot formulate information on its own.

It can never replace the capabilities of the human brain.

Abacus was man's first recorded adding machine. It was in 500 B.C

Abacus was invented in Bobylonio, then pupularized in China

John Napier, Baron of Merchiston Scotland, invents ABACUS.

John Napier, Baron of Merchiston Scotland, invents logs or logarithms.

ABC (Atanasoff-Berry Computer)

Computers had vacuum tubes, resistors, and welded metal joints. They were large, slow, expensive, and produces a lot of heat.

Instead of vacuum tubes, computers used transistors an exciting new invention at thet time. John Barden, Walter Brattain, and William Shockley of Bell telephone Laboratories invented transistors.

Computers relied on a new technology called intergrated circuit. The integrated Circuit is a single wafer or chip that can hold many transistors and electronic circuits.

It was an initiative by Japan's Ministry of International Trade and industry, begun in 1982, to create computers using massively parallel computing and logic programming.

This technological development is to pyt more power and capabilities in one chip called microprocessor. Which have made computers the fastest and most powerful they have ever been.

The fastest type of computer.

They are very expensive and employed for specialized application that require immense amounts of mathematical calculations.

They are very expensive and employed for specialized application that require immense amounts of mathematical calculations.

They are very large and expensive computer capable supporting hundreds, or even thousands of users simultaneously.

They are slower and less than super computers.

They support hundreds and thousands of user at a time.

They are used as a e-commerce and web servers in a large organizations, banks, universities and airlines as databases.

A midsize computer

Is a multi-processing system capable of supporting from 4 to about 200 users simultaneously.

They are also known as midrange computers.

Is generally a synonym for the more common term, Personal Computer or PC.

A compuer designed for an individual.

It uses microprocessor technology to input, manipulate, store, and output data.

Business user uses _____ computers for word processing, accounting, desktop publishing, and for running spreadsheet, and data base management applications.

It is a widely popular with people of all lifestyle because they are powerful, affordable and easy to use.

They are small enough to move easily from oneplace to another and they can operate on batteries.

A small portable computer. Small enough that it can sit on your lap.

Slightly lighter and smaller than a full-sized notebook computer.

A handheld device that combines computing, telephone/fax, and networking features.

It can function as a cellular phone, fax, sender, and personal organizer.

Designed for a fully equipped personal computer that allows a user to take notes using natural handwritting on a stylus or digital pen.

Operate on Mathematical variables in the form of physical quantities that are continously varying. For example: temperature, pressure, voltages etc.

Deal with mathematical variables in form of numbers that represent discrete values of phisical quantities.

All modern computers loptops, and calculators are all____.

Combination of digital and analog computers. It combines both features of both types of computers.

Computers used in hospitals to measure the heartbeat of a patient. Devices used in petrol pump in scientific applications or in controling industrial processes.

The programs are built into permanently in the machine and given task are performed very quickly and efficient. Examples: computers used in monitoring nuclear reactions, outer space missions, oul explorations.

It is capable of dealing to a variety of different problems and are capable to respond to programs created to meet different needs.
