What is the most common form of wiring in data communication application 

Twisted-pair cable


100

Full form of UTB

Unshielded Twisted Pair 


100

The bandwidth of the optic fibers is potentially very _______.

high

100

Two types of microwaves are...

Terrestrial microwave

Satellite microwave

200

It consists of a solid wire core surrounded by one or more foil or wire shields, each separated by some kind of plastic insulator. 

Coaxial Cable


200

Free points

free points


200

Bandwidth range of optic fibers

10 Gbps in single mode

100 Gbps in multi mode

200

They use space-based satellites to relay signals over long distances, enabling global communication, GPS, weather forecasting, and broadcasting services.

Satellite microwaves  

300

They use ground-based towers for point-to-point communication, supporting mobile networks, television broadcasting, and high-speed data transmission over long distances. 

Terrestrial Microwave 

300

What are the 2 types of twisted-pair cables

Unshielded twisted pair cables

Shielded twisted pair cables

300

Free Points

  • free
300

It requires direct line-of-sight. It is unidirectional like microwave, but has much higher speed than microwaves.

Laser Transmission

400

It consist of thin strands of glass or glass like material which are so constructed that they carry light from a source at one end of the fiber to a detector at the other end. 

Optic Fiber


400

Define Thinnet and its segment length

Thinnet: Is a thinner version of coaxial cable and can have maximum segment length of 185 metres

400

Two types of Optic fibers and one significant characteristic of them

Multimode has a segment length of upto 1 km and bandwidth upto 100 Gbps.

Single mode fiber distance is much longer than that of multimode fiber but multimode fiber cables support higher data rates.

400

What can be adversely affected by weather. 

Laser transmission

500

They are low-frequency electromagnetic waves used for wireless communication, including broadcasting (TV, radio), Wi-Fi, and mobile networks. 

Radiowaves

500
Disadvantages of shielded pair cables

Heavier than UTP

Costlier

Required proper grounding at both ends

500

Name the three pieces of optic fiber cables

  • The core,the glass/ plastic through which the light travels
  • The cladding, a covering of the core that reflects light back to the core
  • The protective coating, protects the fiber cable from hostile environment
500

They can travel long distances, penetrate obstacles, and are widely used for data transmission in various wireless technologies.
