Floppy disk working mechanism
Floppy disks work in a similar manner to cassette tapes and the magnetic strip on a credit card.
The floppy disk is constructed of stur plastic that is embedded with a thin iron oxide coating on
both sides. The head of the floppy disk drive easily manipulates the magnetic coating on the disk
to store information. Information is recorded on circular tracks and triangular sections. A special
head in the drive erases the area to be written before recording occurs. This head is wider than
the head used for recording and reading information to ensure recorded information is not
contaminated from previous information recorded nearby.
When reading the disk, the head moves to the appropriate track and sector quickly without
touching the disk. This is an improvement over older cassette tape storage that required a rewind
or fast forward movement to retrieve information. Floppy disks contain a safety slide on the side
of the case. If the slide is moved to create an opening, the drive will not record on the disk.
Introduction
A peripheral is a piece of computer hardware that is added to a computer in order to expand its
abilities. The term peripheral is used to describe those devices that are optional in nature, as
opposed to hardware that is either demanded or always required in principle. There are all
different kinds of peripherals you can add your computer. The main disctinction among
peripherals is the way they are connected to your computer. They can be connected internally or
externally.
Buses
A bus is a subsystem that transfers data between computer components inside a computer or
between computers. Unlike a point-to-point connection, a bus can logically connect several
peripherals over the same set of wires. Each bus defines its set of connectors to physically plug
devices, cards or cables together. There are two types of buses: internal and external. Internal
buses are connections to various internal components. External buses are connections to various
external components. There are different kinds of slots that internal and external devices can
connect to.
Internal
Types of Slots
There are many different kinds of internal buses, but only a handful of popular ones. Different
computers come with different kinds and number of slots. It is important to know what kind and
number of slots you have on your computer before you go out and by a card that matches up to a
slot you don’t have.
PCI
PCI (Peripheral Component Interconnect) is common in modern PCs. This kind of bus is being
succeeded by PCI.

27. Memory Cache speeds up a computer by storing data
the computer has recently used. There are 2 types :
Internal & External
28. External Cache
If the computer cannot find what
it needs in the Internal Cache, it
looks in the external cache. This
is usually located on the
Motherboard. In some CPU chips
the External cache is built in.
Internal Cache
When the computer needs
data it first looks in the
Internal cache. This is located
on the CPU chip and provides
the fastest way for the
computer to get data.

30. Motherboard
This is the main circuit board that all of the other
internal components connect to.
The CPU and memory are usually on the
motherboard. Other systems may be found directly
on the motherboard or connected to it through a
secondary connection.
For example, a sound card can be built into the
motherboard or connected through PCI (Peripheral
Component Interface).

interface is a method of adding additional devices, such
as hard drives or scanners, to the computer.

monitor.
Sound card
This is used by the computer to record and play audio
by converting analog sound into digital information
and back again.
AGP
Accelerated Graphics Port is a very high-speed
connection used by the graphics card to interface
with the computer.
37. SERIAL PORT
Considered to be one of the most basic external
connections to a computer, the serial port has been an
integral part of most computers for more than 20 years.
Although many of the newer systems have done away
with the serial port completely in favor of USB
connections, most modems still use the serial port, as
do some printers, PDAs and digital cameras. Few
computers have more than two serial ports.
38. If you have a printer connected to your computer, there is
a good chance that it uses the parallel port. While USB is
becoming increasingly popular, the parallel port is still a
commonly used interface for printers. Parallel ports can be
used to connect a host of popular computer peripherals:
• Printers
• Scanners
• CD burners
• External hard drives
• Iomega Zip removable drives
• Network adapters
• Tape backup drives
Parallel Ports
39. The goal of USB is to end all of these headaches. The Universal
Serial Bus gives you a single, standardized, easy-to-use way to
connect up to 127 devices to a computer.
Just about every peripheral made now comes in a USB version. A
sample list of USB devices that you can buy today includes:
Printers Scanners Mice Joysticks Flight yokes
Digital cameras Webcams Scientific data acquisition devices
Modems Speakers Telephones Video phones
Storage devices such as Zip drives Network connections
Connecting a USB device to a computer is simple -- you find the
USB connector on the back of your machine and plug the USB
connector into it.

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
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
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)
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
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
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
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
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
