In this unit we have learned many things like about Parallel Port Prinnters (LPT)
Troubleshooting of mouse , keyboard, scanner ,mike , printers etc i.e see if they are working properly when connected
And about various input and output devices like keyboard,monitor etc .in detail
And about various ports and cables like sata port ,optical port and hdmi cable .

input and output trouble shooting where we can determine the cause of device problem
trouble shooting in different parts like

1. keyboard

2. mouse

3. scanner

4. switches

5. webcame

6. monitor etc.

then there are ways to correct them also like:

1. checking erroe lock

2. checking attributes of a device

3. defining new device

4. changing the attributes etc.

about input and ouput cables :

1. 10/100base-T(sheilded)category 5

2. T1 (sheilded) category 8

3. 2 conductor (sheilded ring )

list of computer cables

HDMI cables

DVI cables

VGA cables etc .

also 2 types of ports are there :

internal

external

Input/Output devices and their troubleshooting:
We learn about the troubleshooting of the various I/O devices like keybaord, mouse, scanner, etc. This could be du to connectvity issues, etc.

# data[].attributes.body
We have learnt many new and different troubleshooting issues and how to overcome some of those
1)Mouse : The cause of mouse not working can be loss or power connnection or outdated update which can be resovled

2)Keyboard: maybe your computer does not detect the keyboard here you can go to device manger and resolve your issues

many other parts such as speakers, scanners, webcams, monitors, etc. have issue which can either be resolved or the part has to be replaced

also in unit 3 we learnt about cables and ports

how to do troblueshooting the devices and finding what kind of problem does device have.
various new technologies about troblueshooting.
checking the error log
checking the state of devices

# data[].attributes.body
We learnt about different types of input and output devices such as scanner, printers, mike, monitors, keyboard, mouse etc. We learnt about the troubleshooting of these different input and output devices for example we learnt about how we need to install and update our drivers for new software in printers and scanner and we also learnt about We learnt about ports and how different devices use different types of ports and how damaged ports can be the cause of your hardware device not functioning properly.
In keyboards we learnt about cleaning of the keyboard is vital because dust partcles and debris can obstruct the keys from being pressed and can cause inconvenience for the person typing.
To clean the keyboard we need to just hold it upside down so that all the debris falls out we can also use air blowers to clean it out.
In mouse we learnt that we should not keep any paper or cloth underneath it as doing so obstructs the optical sensor underneath the mouse. We should also make sure that the cables are connected properly to the pc and none of the ports are damaged.
For printers we learnt about how the colour of the light indicated different problems in the printer for example orange light says that their is an error in the pc and the green light says thaty the pc is turned on

In unit 3 , we learnt about troubleshooting different types of devices like mouse , printers , Speakers , webcam , microphone etc .
Some new terminologies which I learnt and understood are :
Parallel (LPT) printers
DVI cables - They are cables which are connected to LCD monitors and video card .
We were also revised about the different I/O devices.

LPT port: (Line print terminal)
It's a parallel connection to a printer or other device on a personal computer.

PS/2 cable:
It is used to connect a computer mouse or keyboard to an IBM compatible computer. It is now replaced by USB cables.

VGA cable: (Video graphic ray)
DVI cable: (Digital visual interface)

# data[].attributes.body
In Unit 3 We learn about the Output and Input Devices and about there trouble shooting issues and how to solve them.
There were different types of Input and Output Devices such as: keyboard, mouse, scanner, printer, webcam, monitor, speaker, mike.
We learn about how a device and its troubleshooting issues can be solved in a various methods, and we learn about different types of I/P and O/P cables such as VGA cable, HDMI cable, DVI cable
