Case SummaryFrom this report we can learn about two major lab lessons. They are listed as under.

1. How to view information about a computers components from System DeviceManager.

2. Viewing the back panel of a computer and identifying the different ports foundthere. We can also see how it is connected to its respective device.

These two lesson lab is very important for every computer user to know and understand.

Computer is one of the most widely used devices and we should know the very basics of

using a computer. The first lesson lab teaches us how to view any required information

about a computers hardware from inside the computer. The second lesson lab on the

other hand guides us through the various ports at the back panel of a CPU.

Both the lesson labs are very essential for us to know for everyday use of computer.

The basic standard portsThe back panel of the computer consists of various ports through which external devices

such as printer, keyboard, scanner, modem etc. are connected. This allows instructions

and data to flow between the computer and the device. The computer ports are commonly

referred to as Input/Output ports (I/O ports). Most of the ports are polarized, permitting

the cable to be plugged in only in the correct direction.

The basic standard ports that are very commonly used among desktop users are given asfollows:

1. AC Adapter- This three pronged plug looks like a recessed power plug. It connects

to the ocmputer power cable that plug into a power bar or wall socket.

2. PS/2 orMouse and Keyboard portsThese ports accept the keyboard and mouse

plugs. The ports are located at the top of the back panel. The connecters are color-coded.Usually the purple connector is for the keyboard and the green connector is for the

mouse. In order to connect the mouse and keyboards, the color of the cable should match

the connector or else the computer will not boot properly. The mouse and keyboard use

PS2 connectors. The PS2 connectors were invented by IBM for their model PS2

computers.

3. USB ports The back-panel of the computer consists two USB ports, that accept

plugs of a wide range of devices such as keyboards, mouse, portable media players ,disk

drives etc. It has become a common place on other devices such as smart phones ,PDAs

and video game consoles.USB ports are generalised into three different criteria naming-

USB v1.00,USB v2.00 and USB v3.00, of which USB v3.00 is the fast data transactor.

4. Audio portsGenerally the back panel of the computer consists of three audio ports.

The three basic ports provided by all motherboards with integrated sound are the micro

phone, line in and line out ports. These ports are compatible with audio devices using the

3.5mm audio jack common to most desktop speakers and headphones. The microphone

port is designed to accept input from microphones using 3.5mm audio port. On most

computers the port is colour coded pink. The line in port is designed to accept audio input

from devices other than the microphone, it can be used to connect stereo system. It is

color coded yellow. The line out port is commonly used for desktop speakers or

headphones but is compatible with any device using the appropriate audio connector. The

port is generally color coded green.

5. Network port - It is the actual location where a network cable is plugged in. Network

ports provide users to access to local networks and the Internet.

6. Modem ports - A modem port is used to connect a computer to the internet using

standard telephone service. A modem port is similar to a regular telephone jack. Theconnection is made by inserting a standard telephone line into the modem port. The port

uses a telephone line, when connected; the line will not be used for any other calls while

connected.

7. Parallel port - The parallel port is used to connect older printers. The parallel port

allows for a one-way transmission of data from the source to a secondary device, such as

printer. The parallel port is found on the back of IBM compatible computers and is a 25-

pin (type-DB-25).The DB-25 has an 8 bit data bus. The standard parallel interface for

external devices can transfer 8bits at a given period of time.

8. Serial ports - A DE-9 connector is used for a serial port. Serial port is a serial

communication physical interface through which information is transferred in or out one

bit at a time (in contrast to parallel ports).Serial ports are mainly used to connect external

modems.

9. Monitor/VGA port - Either imbued graphics card of the motherboard or extended

graphics card contains display ports. Display ports have developed to give more vivid

quality of pictures. This ports are subdivided into 3 main criteria 1.VGA adapter 2.DVI

adapter 3.HDMI adapter.

Expansion Ports

When a more efficient and powerful PC is needed it needs some specialized ports to

enhance its compatability with other devices. These ports sits on the empty spaces of the

back-panel of a CPU.

1. Extended Graphics Cards Port

2. Extended Audio CardsPort

3. MIDI Ports

4. Gaming Port5. SCSIPort

6. TV cards Port

1. Extended Graphics Cards Port - A graphics card is an expansion card which

generates output visuality of a computer and these family of expansion cards are situated

in the motherboards expansion slots. They offer the traditional VGA adapter(A type

ofD-sub connector standard on most video cards) along with new DVI-ports or HDMI-

ports, through which a display adapter is connected.

2. Extended Audio Cards Port- Audio or Sound cards is an internal addition of a

CPU.This device faciliates the input and output of analogue sound to digital sound or

vice-versa through comptuer programs. Sound cards are generally found on PCI slots.The

ports of an internal sound card are color coded and they use 3.5mm audio-jack.

Green- for audio output to external soundsystem

Pink-An input port for microphone

Blue- It recieves analog sound data off other connected devices

Black- An output to surround system

Orange-Analog line level audio output for center channel speaker and subwoofer

3. MIDI Ports-MIDI short forMusical Instrument Digital Interface, is an electronic

musical instrument industry specification that enables a wide variety of digital musical

instruments, computers and other related devices to connect and communicate with one

another.A DA-15 male connector is needed to setup the connection onto the computer.

4. Gaming Port- IBM PC first introduced the concept of game ports. Old generation

PCs were able to connect joystick for the purpose of better gaming experience.Game

ports were initially located on specialized expansion slot of the motherboard but later

with the advancement of technology USB replaced Game Ports.

5. SCSI Port - Small Computer System Interface (SCSI) is a set of standards for

physically connecting and transferring data between computers and peripheral devices.

The SCSI standards define commands, protocols, and electrical and optical interfaces.

SCSI is most commonly used for hard disks and tape drives, but it can connect a wide

range of other devices, including scanners and CD drives, although not all controllers can

handle all devices. Later SCSI ports were superseded by USB ports.

6. TV cards Port-A TV card is a kind of television tuner which is found on PCI slots.

A TV card enables the computer to recieve TV signals.Moreover, it can function as video

capture card which allows it to record TV programs onto the hard disk.Monitors are

connected to it by mini-Din or RCA connectors.

Recommendations

1. System Device Manager is reached in different ways depending on the version ofwindows.

2. Never change anything from the properties of the System Device Manager.3. For the PS/2 ports the mouse and keyboard must be connected in the green and

violet port respectively otherwise the computer will not boot properly.

4. The connectors that have pins must be connected to their respective ports in theright method or else the pins might break and the connector can no more be used.

5. For the audio ports the green, pink and yellow/blue jack should be connected withthe respective colored ports for proper functioning of the ports and the devices.

6. Network ports and Modem ports should be connected properly for access to anetwork or the internet.

7. When we need a powerful computer we add different adapters on the expansionslots of the motherboard. We add extended audio adapter, display adapter etc to

increase the performance of our computer.8. Gaming port andSmall Computer System Interface (SCSI) port is now replaced

by USB ports.

Conclusion

Computer is a very essential thing in our life. During the past 10 years, the use of

computers in education has increased dramatically and a wide range of educational

computer programmes are now widely available for individual and classroom use. Yet we

do not know many of the things related to the computer. So the motive of this report is to

teach us the very basics of the ports at the back panel of a CPU and how to view required

information about different components of a computer.

Initially, we saw how to view different components of a computer. We viewed and

gathered information about a computers components from System Device Manager.

Seeing the properties we could identify if the device is working properly or not.

Finally, we saw the basic ports that can be found at the back panel of a CPU. Then we

saw the extended ports which makes the computer more efficient and powerful. The basic

ports were AC adapter, PS/2 or Keyboard and mouse Port, USB Ports, Audio Ports,Network Port, Modem Port, Serial Port, Parallel Port and Monitor/VGA Port. The

expansion ports were Extended Graphics Cards Port, Extended Audio CardsPort, MIDI

Ports, Gaming Port, SCSI Port and TV cards Port.

We thank Almighty ALLAH for giving us the patience to write this report and submit it

on time successfully. We thank our course instructor Mohammad Monzur Morshed

Bhuiya for guiding us through and bestowing us with enriched knowledge and

information throughout the semester.
