Solution

What is the difference between UTP and TP?

There are two common types of twisted pair cabling, STP and UTP.

STP               UTP

Shielded Twisted Pair. Unshielded Twisted Pair.

STP cables are shielded. UTP cables are unshielded.

STP is used in more high-end applications. UTP cables are more prevalent in SOHO networks.

STP cable cost more per meter than UTP. UTP cables are cheaper than STP.

STP cables are heavier per meter compared to UTP. UTP cables are lighter per meter compared to STP.

STP cables are better at maximizing bandwidth compared to UTP

What is the difference between duplex and simplex communication?

Simplex communication                                                             

In Simplex communication, information travels only in one direction.

There is no type.

Example of simplex communication: TV broadcasting

Duplex communication

In Duplex communication, information travels in both the directions.

It is of two types, half duplex and full duplex.

Example of duplex communication: Telephone

Define the acronym MODEM.

Modulator – Demodulator

What does it mean and what does it do?

A device that encodes digital computer signals into analog/analogue telephone signals and vice versa and allows computers to communicate over a phone line.

It translates the data that is sent to it so that it can display on our computer.

Computer information is stored digitally, but information sent over phone and cable lines are analog waves. So our modem takes the analog waves, changes it to digital and delivers it to our computer.
