2. Introduction
In the past connecting devices to your computer are at ease when we only use the keyboard, mouse, monitor and printers but now We have to deal with USB, FireWire, network jacks and an assortment of audio and video connections. All those will be presented in this presentation
Simple PC With only mouse New types of Connectors USB are the
keyboard and printer for new devices as most popular
Technology grew
It is easy to connect all your devices to your computer in the past when there are only keyboard, mouse,printer and monitor
present.As technology grows allowing more and more device to be connected with our personal computer. Those new devices are usually connected to our pc via the USB, FIREWIRE cable.
and also at the age of internet, we must equip ourself with network cards and network cables. All those will be explain in the next slide

3. What are Ports?
On computer, a port is generally a specific place for being physically connected to some other device, usually with a socket or plug which we call Connectors
Typical Computer Port found behind a desktop PC
First we take a look at rear side(Back) of a Typical computer.
we can see the ports which are differenciate by colours
I will only explain some major parts which consist of Ps/2 port
USB ports,network Port,VGA ports

4. What are Connectors?
A connector is any connector used within computers or to connect computers to networks, printers or other devices.
Many types of computer connectors
next as seen on the picture those are connectors
i am sure everyone have the experience of pluging those wire plug into thier old printers. Those plugs are call connectors
They can be either male(with pins) or female type of connectors (without pins)

5. The PS/2 Connector
The PS/2 connector are use for connecting keyboard and mouse on the modern PCs. The PS2 mouse connector and port is usually green in colour to distinguish it from the PS2 keyboard, which is purple.
Ok now here as seen on the picture
it shows PS/2 Connector and ports as hightlighter
Those ports & connector behind to your keyboard and mouse
It is only for data input

6. The USB Port
Universal Serial Bus: a protocol for transferring data to and from digital devices. Many digital cameras and memory card readers connect to the USB port on a computer.
Next The USB Port also know as Universal Serial Bus
I am sure everyone know about USB, right now its very popular for connecting device like mp3players, Camera
and many other card readers. As i reasearch through the internet, it can connect up to 127 devices up to date
It is for input and output data. for example a pendrive
you can read and write data from it

7. The Firewire IEEE 1394 Port
A type of cabling technology for transferring data to and from digital devices at high speed. FireWire are typically faster than those that connect via USB.
Firewire is a new technology after the USB
having same ability as the USB
It is typical faster than the USB
however it is not popular

8. The RJ45 Ethernet Port
LAN or (Local Area Network) uses a CAT5 cable and a RJ45 connection. The CAT 5 cable  is also called the Ethernet Cable.
Network connection generally uses a 10/100 Mbps speed. This means it has two different speeds 10 Mbps and 100 Mbps.
It is obvious we need a network card and cables to conduct networking between our computer. From the picture as show
those ports are built in network card ports in a computer
also known as Rj45 ports. we use a type of Cable call CAT5
cable to connect into the RJ45 port for networking while the other end of the CAT5 cable to a hub or switch then interconnect with other computer

9. DB25 Parallel Port
The printer connects to your computer with a Parallel connector. This connector has 25 pins.
Parallel means the device is capable of receiving more than one bit at a time (that is, it receives several bits in parallel).
The DB25 cable for older printers or scanner
are still inuse because some companies and homeuser still depend on thier old printers for printing.
The parallel port is device which is capable of receiving more than one by at a time
