COMPUTER HARDWARE



HARDWARE

The components or devices that are connected to a computer are collectively known as
 hardware. For example, monitor, mouse, keyboard, speakers, and printer come under the term hardware.

INPUT - OUTPUT DEVICES.
As you know, a computer follows the I-P-O cycle for processing . Therefore all the devices can be categorized as input and output devices, and processing devices.
The input devices are used to give instructions to the computer. For example  ,keyboard and mouse.
The output devices are used to display output of an operation. For example , monitor and printer.

KEYBOARD
The keyboard provides different keys to perform various operations, such as the cap lock, backspace , num lock, home, end.

MOUSE
A mouse is a small device that is connected to the system until by means of long wire. This is another input device, whose movement causes the corresponding movements of a pointer on the screen. it usually has two or three buttons using which the user can select options from the screen.

MOUSE


VDU
Now that you are familiar with some input devices of the computer , let us take a closer looks at an output device. Data that has been processed needs to be displayed to the user. This is done using the monitor or the VDU . The VDU is similar to a Tv screen and can display both text and graphic images. The display can be either in black or white color.

VDU


PRINTER
The output on the VDU cannot be stored for later reference . For a permanent output, you would requires a printer that is also a common output device Using the printer , you can obtain output  on paper. Printers are capable of printing at very high speeds.

PRINTER

MICROPHONE
A microphone is an input devices that allows a user to speak to the computer to enter data and instructions into the computer or it is used to record sound.


MICROPHONES
.


JOYSTICK
A joystick is a pointing device with a vertical lever mounted on a base. it is mainly used for computer games and ultrasound scanners in hospitals.
JOYSTICK



SCANNER
A scanner is a input device used to capture information, such as, photographs and documents on paper
and translate the information into a raster (bitmap) computer image.

SCANNER

SPEAKERS
You can use speakers on a multimedia machine to listen to the sound files, which can be audio, recorded by a microphone or audio CDS.

IT FUNDAMENTALS.

 

COMPUTER OVERVIEW.

Computer is an electronic device used for storage and processing information. A computer has moved through various states of development and improvement. These states are referred to as generations of computer.


Most computers follow the basic principle of input, process, and output. A computer consists of two components, hardware and software. A computer has various types of files on a storage media: text storage, graphic storage , and audio storage media.

INTRODUCING COMPUTER SYSTEMS

Computer is an electronic device that stores, retrieves, and processes data, and can be programmed with instructions. A is computer is computer is composed of hardware and software, and can exist in a variety of sizes and configurations.

COMPUTER APPLICATIONS

To begin with, you must understand the impact of computers in the world today. Computers are affecting our lives in one way or the other. Airline and railway reservations, telephone and electricity bills, banking , medical diagnoses, weather forecasts... the list of services using computers is almost endless.

You would have probably noticed that some applications of computers have made life much easier for you - your air ticket is now issued in a matter of minutes and your credit card is processed very fast.

You may be suprise to know that the computer cannot perform any task without you. The computer needs to be instructed on exactly what it has to do.

GENERATIONS OF COMPUTER 

While it would not be wrong to say that the evolution of the computer began with the man's need to count, the actual growth, which have come to be called computer generations. Major technological develpments in each generation led to smaller,  cheaper , more powerful and more efficient and reliabble computers.

FIRST GENERATION - 1940 - 1956: VACCUM TUBES.

The first generation computers used valves leading to huge size and cost. The UNIVAC and ENIAC computers are examples of first generation computing devices.
fig 1.1 first generation computer.
The UIVAC was the first commercial computer delivered to a bussiness clients, the U.S census Bureau in 1951.

fig.2.2  second generation computer 

 SECOND GENERATION - 1956- 1963: transistors

The secon generation computer used transistors. in span of ten years, transistors that were more efficient and cheaper replaced valves.

fig 3.3 third generation computer

THIRD GENERATION COMPUTERS - 1964 - 1971 : Integrated Circuits.


The Third generation computers used intergrated circuits (IC) . in the early sixties, a major breakthrough was achieved when hundreds of transistors could be placed on a single silicon chip. IC became the basis of the third generation.

fig 4.4 fourth generation computer.

FOURTH GENERATION - 1971- PRESENT: microprocessors

 The fourth generation computers used microprocessors. with the introduction of very large scale integration (VLSI), thousands of transistors could be placed on a single chip.
fig 5.5 fifth generation computer
FIFTH GENERATION - PRESENT AND BEYOND: Artificial intellegence

The fifth generation computer tries to infuse intelligence into computer. The development of these computers is still in its infancy, but examples can be cited of various speech recognition systems and robots.
