Computer esentials

1. computer hardware

2. What is a computer?

3. different types of computer

4. language word classifying



Questions1. have you got a computer at home, school or work? what kind

is it?

2. how often do you use it? what do you use it for?

3. what are the main components and features of your computer

system?

Computer hardware



the keyboard



In computer keyboard is a peripheral input device or in part inspired by the keyboard of the

typewriter, which uses an arrangement of buttons or keys, to act as mechanical levers or

electronic switches that send information to the computer

the mouse

Is a pointing device used to facilitate the handling of a graphical environment on a computer. It is

usually made of plastic and is used with one hand. Detects relative movement in two dimensions

by the flat surface on which it rests, usually reflected through a pointer or arrow on the monitor.

the monitor

The computer monitor or computer screen, although it is commonly called "screen" is an output

device, using an interface shows the results of processing a computer.

horns

allow us to hear different kinds of sounds emitted by the computer, which sometimes indicate

something in particular.

Printer

A printer is a computer peripheral that allows you to produce a permanent copy of text or graphics

of documents stored in electronic form, print them on physical media, usually paper or

transparencies, using ink or laser technology.

CPU

The central processing unit or CPU (the acronym for central processing unit), or just the processoror microprocessor, is the component of computer and other programmable devices, which

interprets the instructions contained in programs and processes data.

wifi router

with a wireless router through which you can create a network of wireless internet access at

home. Yes, you heard me right: no wires. Because a wireless router is able to createnetworks that

expand internet your living space and not break the style of your home.

WHAT IS A COMPUTER



what is a computer?

A computer is an electronic machine which can accept data in a certain form,

process the data, and give the results of the processing format as

information.

first, data is fed into the computer's memory. then, when the program is run,

then computer performs a set of instructions and processes the data. finally,

we can see the results (the output) on the screen or in printed form

a computer system consists of two parts: hardware and software. hardware

is any electronic or mechanical part you can see or touch . software is a set

of instructions, called program, which tells the computer what to do. there

are three basic hardware sections: the cemtral procesing unit (CPU) main memory and peripheralsperhaps the most influential component is the

central processing unit. its function is to execute program instructions and

coordinate the activities of all the other units. in a way, it is the `brain` of the

computer. the main memory (a collection of ran chips ) holds the instructions

and data which are being processed by the CPU. peripherals are the physical

units attached to the computer. they include storage devices and

input/output devices

storage devices (hard drive, DVD drives or flash drives) provide a permanent

storage of both data and programs.disk drives are used to read and write

data on disks

input devices enable datato go into the computers memory. The most

common input devices are the mouse and the keyboard. output devices

enable us to extract the finished product from the system. For example, the

computer shows the output on the monitor or prints the results onto paper

by means of a printer.

On the rear panel of the computer there are several ports into which we can

plug a wide range of peripherals-a modem, a digital camera, a scanner, etc



They allow communication between the computer and the devices. Modern

desktop PCs have USB port and memory card readers on the front panel.

Language work classifying

Look at the help box and then use suite classifying expressions tó complete

these sentences

1 a computerare classified into x types/categories hardware and software

2 peripherals are classified bythere: types input, output and storage devices

3 a word processing program consist software which lets the user create and

edit text.

4 x is a types of network architecture peer to peer, where all computers have

the same capabilities, and client server (e.g the internet) where server store

and distribute data, and client access this data.

CONCLUSION

Us as a team we came to the conclusion that the computer

makes everyday life easierbecause we can communicate through the

network, do work easily.

also the input and output peripherals are major components of a

computer because these are part of this. so the human being in the

course of time to improve these components for everyday use.
