2. Introduction
The computer is made up of two main parties which are the software and
hardware.
the software is the virtual part of the computer, more exactly the programs you
have installed such as Windows or Word.
This software is divided into two class are the operating system and TSRs.
When speaking of a MS-DOS, Windows XP, Linux or Unix among others are
talking of an operating system and when speaking of Microsoft Office, an
OpenOffice, Corel Draw, Audocad, Photoshop and others are talking a resident
program which is mounted on the operating system which allows operation.
Hardware is the physical or tangible computer part, it is all that you can see or
touch as the keyboard or the mouse and it is this hardware or physical part
which then is to show and explain in a more detailed way.
3. Tower
It is a metal or plastic housing, and perhaps most important part of the
computer. Inside are components that make all other parties fulfill their
function. It is equivalent to the brain of the computer.
In parts of back and forth has ports and buttons where you can
connect more parts or turn on and turn off the computer. Its location
changes depending on the computer model.
4. On the front of the tower you can
find...
Power button
Eject
DVD-ROM
USB ports
CD/DVD-ROM
Audio input
and output
5. Power button
This button is used to turn on and off your computer. Many computers have power-saving mode such
as sleep, hibernation and rest.
CD / DVD-ROM
allows the computer to read and write CDs and DVDs. The latest drives can read and write to Blu-
Ray to HD videos.
A typical Blu-ray stores more data than DVDs or CDs.
Eject DVD-ROM
This button ejects or open the CD or DVD drive.
USB ports
They serve to connect the mouse, keyboard, printer, digital camera and more; They are in the front
and back of the machine.
Audio input and output
To easily connect speakers, microphones and headphones, many computers include audio ports on
the front of the computer case.
6. Back of the tower
Plug
Ethernet port
Input / Output Audio
USB ports
Or VGA
monitor port
Serial port
Port PS/2
Expansion slots
Parallel port
7. Plug
Here it is where you connect the power cord to the computer. That is, the cable that will supply all power for the computer to be
turned on and working.
Ethernet port
This port is similar to the modem. There, the network cable, which allows you to connect to the Internet from your computer is
connected.
Input / Output Audio
There the speakers and microphone are connected if they do not come built into your desktop computer
USB ports
Here the mouse, keyboard, printer, digital camera and any peripheral that comes with that kind of connection in the cable is
connected. In addition, there is where you connect the USB memory so you can view the information found within them. In most
desktop computers, these ports are found both in the back and the front.
Or VGA monitor port
Here the cable connecting the monitor with the tower is connected. This may vary depending on the type of screen.
Serial port
In this port you can connect peripherals such as digital cameras and speakers. in the most modern equipment it has been
replaced by USB purestos.
Port PS/2
This type of port was used by older equipment to achieve the connection of mouse and keyboard. Currently, it is being replaced
by USB ports.
Expansion slots
These are spaces where plastic or slots for expansion cards video, sound or network connect.
Parallel port
In the old models of computers, this port is used to connect the printer or scanner. In newer models, also it has been replaced by
USB ports.
8. Keyboard
The keyboard is one of the main tools we use to interact and enter data into the
computer. Its keys are classified into 6 areas. Let's see what they are:
Function Keys Control Keys
Alphanumeric
keys to type or
Numeric keyboard
special keys
Joypad
9. Function Keys
It is the first line of keys and are at the top of the keyboard. They are represented as F1, F2, F3 ...
and they serve to perform a specific function or to access shortcuts of programs.
Control Keys
They are used alone or in combination with numbers to access functions or perform certain actions.
The most used are Ctrl, Alt, Esc and the key with the Windows logo.
Alphanumeric keys to type or
Here are all the letters, numbers, symbols and punctuation. These keys are normally found on a
typewriter.
Numeric keyboard
Used to enter numerical data quickly. Keys and symbols are grouped in the same way as they
appear in the caluladora.
Special keys and scroll
These keys are serving you to scroll through documents or web pages and edit text. Among them
they are: Delete, Home, End, Page Up, Page Down, ImpPt and the arrow keys.
10. Monitor or screen
Here the information in your computer looks and works thanks to a video card that is
inside the tower.
There are several types of monitors, very large as a box and other flat as a painting on
the wall.
Most have buttons to change the screen display features
11. Power cord
It is the link between the electrical outlet and your computer, this depends on receiving
electrical power. If the power cord is not plugged in, the computer will not start.
Power cable power plug to your computer.
Usually you need two cables of these, one for the tower and one for the screen.
We recommend using a stabilizer power to protect your computer from high voltage
spikes.
The stabilizer prevents your computer from burning. It also gives you some temporary
power in the event of a power outage that you may observe the latest changes.
12. Mouse
It is the part of computer that lets you interact with objects on the screen by clicking on
them. The mouse is part of your computer peripherals.
Usually, the mouse or mouse has two buttons: the left, which you used to open, drag,
selection and execution functions. The law allows you to access additional functions on-
screen commands.
Most mice have a scroll wheel known as scroll, with it you can scroll through the
document from top to bottom and back part.
Computer mouse or mouse.
You can also find wireless mice that are easier to bear because they have no cables
and you can connect via a Bluetooth connection, but these need batteries.
The mouse cable is connected to the tower through a USB port or a puertoP/S2.
13. Peripherals for your computer:
Desktop computers usually are composed of a tower, monitor, keyboard and mouse, but
you can connect more devices, which are also known as peripheral.
Printer:
It is used to print all the files on the computer creandos. There are many types of
printers and all prices.
Scanner:
It is used to copy and save the contents of a sheet into the computer as a digital image.
There are printers that come with integrated scanner.
14. Microphone
It is an audio input device. You can connect the computer to record sound or the
Internet to communicate with others. Many computers come with built-in screen or
monitor, computers potátiles especialemente the microphones.
Speakers
Are devices that give audio output to the computer, thanks to them we can hear the
sound of music or video you are playing.
Depending on the model, you can connect to the USB port or audio.
Some computers include built-in monitor speakers.
15. webcams
A webcam or webcam is a type of input device with which you can record videos or take pictures.
Also, you can use it to make video calls with people anywhere in the world, streaming video on the
network in real time.
Joystick
It is a device used to control computer games. Although there are several types of drivers, you can
use your mouse and keyboard to control most games.
Digital camera
Capture an image or a video in digital format. When connecting the camera to the USB port, you can
transfer all the content you have there. Then you can print photos, send them by email or post them
on the web.
Other devices
When you buy an electronic device like a mobile phone, an mp3 player, tablets and other devices,
you should check if it brings including a USB cable. If so, it means you can connect it to your
computer and transfer all the information.
16. CPU or Processor
The processor or Central Processing Unit CPU is the brain of the computer.
Your job is to execute all orders that you give via the keyboard and mouse.
Each time you press a key or make a mouse click you are sending orders and
instructions to the CPU.
The processor is a square 2 inches ceramic with a silicon chip the size of a
fingernail and is located inside the tower.
What's inside the computer?
17. Motherboard
Its English name is motherboard and infrastructure components of your computer. It is a
plate that keeps running the CPU, memory, connectors for hard disk and optical drives.
Also, all connections to the computer ports and USB ports.
This card sets the limits upgrade the components of your computer.
18. Power supply
The power supply takes the power from the outlet to the computer and sends it through
the cables to the motherboard and other components.
Of the power supply it depends on the current input to the computer.
19. Memory RAM
It is the short term memory of the computer. Its main function is to remember the
information you have in each of the applications running on the computer while it is on.
Memory RAM or short-term desktop computer.
This short-term memory only works when the computer is on.
RAM is measured in megabytes (MB) or gigabytes (GB). The more RAM your computer
has, the more things you can do at the same time. If you do not have enough RAM,
you'll notice that your computer becomes slow when having many open programs.
20. Harddrive unit
It is the center of computer data storage. This is where the software is installed and
where all kinds of documents and files are stored. The hard drive saves and protects
long-term data, which means that will be saved even if the computer is turned off.
Mechanical hard disk drive for desktops or desktop.
When you run a program or open a file, the computer takes some of the data from the
hard disk into RAM so you can access them more easily and quickly.
When a file is saved, the data back to the hard drive are performed.
The faster is the hard drive of your computer can boot faster, save and load files and
programs.
21. Expansion cards
Most computers have expansion slots that allow you to add different types of cards.
These cards are known as PCI (Peripheral Component Interconnection) cards; it may
not be necessary to add PCI cards to your computer because most already bring all
cards installed, either video, audio or network.
If you want to increase the performance of your computer or upgrade the capabilities of
an old computer, you can add one or more cards to where you allow compatibility with
your motherboard. These are some of the most common types of expansion cards:
Graphics card
Processes all the information you see on the monitor. Most computers have an
integrated on the motherboard instead of having a separate video card card.
If you really like video games, you can add a card faster to one of the expansion slots
video.
22. Sound card
This card is responsible for what you hear on the speakers or headphones. Most computers have
built-in sound card into your motherboard, but this can be upgraded by buying one with higher quality.
PCI network card for desktop or desktop.
Network card
It allows the computer to connect to a network. The network card can be connected to an Ethernet
cable or a wireless network also known as Wi-Fi.
Most new computers have a network card built into your motherboard, otherwise you can add one
into an expansion slot.
Bluetooth card
Bluetooth is a wireless communication technology for short distances. Often it used computers to
communicate with wireless keyboards, mice and printers.
It is usually built into the motherboard or on a wireless network card. For computers that do not have
Bluetooth, you can buy a USB adapter or dongle.
