Question

Good morning !

Refer to the attachment and answers the question...

1.) what is a computer network ?
2.) what is the role of a transmission medium in a computer network ?
3.) write any two advantages of network
4.) what is a coaxial cable differentiate between Broadband and baseband coaxial cable .

I have already translated the questions from Korean to english, so please answer them correctly..don't spam. ​

Answer 1

Answer:

1. A network is a collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to allow data sharing. An example of a network is the Internet, which connects millions of people all over the world. To the right is an example image of a home network with multiple computers and other network devices all connected.

2. Transmission media is a communication channel that carries the information from the sender to the receiver. Data is transmitted through the electromagnetic signals.

The main functionality of the transmission media is to carry the information in the form of bits through LAN(Local Area Network).

It is a physical path between transmitter and receiver in data communication.

3. * Sharing devices such as printers saves money.

*Site (software) licences are likely to be cheaper than buying several standalone licences.

4. A Coaxial cable consists of central copper wire surrounded by insulation and then a shield of braided wire. It is used in transmission of video, communications and audio specially in the cable television industry.

Difference between Broadband and Baseband Coaxial cable is that Baseband Coaxial cable supports quick transmission of a single signal at a time and is mainly used for LANs whereas Broadband Coaxial cable transmits multiple signals at the same time and is used for longer distances.

here is your answer.

Answer 2

1. A network is a collection of computers,

servers, mainframes, network devices,

peripherals, or other devices connected

to allow data sharing. An example of a

network is the Internet, which connects

millions of people all over the world. To

the right is an example image of a home

network with multiple computers and other

network devices all connected.

2. Transmission media is a communication

channel that carries the information

from the sender to the receiver. Data is

transmitted through the electromagnetic

signals.

The main functionality of the transmission

media is to carry the information in the form

of bits through LAN(Local Area Network).

It is a physical path between transmitter and

receiver in data communication.

3. * Sharing devices such as printers saves

money.

*Site (software) licences are likely to be

cheaper than buying several standalone

licences.

4. A Coaxial cable consists of central

copper wire surrounded by insulation and

then a shield of braided wire. It is used

in transmission of video, communications

and audio specially in the cable television

industry.

Difference between Broadband and

Baseband Coaxial cable is that Baseband

Coaxial cable supports quick transmission

of a single signal at a time and is mainly

used for LANs whereas Broadband Coaxial

cable transmits multiple signals at the same

time and is used for longer distances.

Hope it helps u..!!
