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?

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.
