Computer Communication & Networking Concepts
Q1
Among the following options, which are the five main components of a communication system?
Explanation
A communication system commonly involves a sender, message, receiver, communication medium, and protocol. The protocol provides rules for how the communication takes place.
Q2
What is the minimum number of wires needed to send data over a serial communication link?
Explanation
Serial communication transmits data one bit at a time over a communication path. In its simplest form, a single wire can carry the data signal, with a common ground or reference assumed.
Q3
Which of the following is an example of a bounded transmission medium?
Explanation
Bounded or guided transmission media provide a physical path for signals. Coaxial cables, waveguides, and fiber-optic cables all guide signals through a defined physical medium.
Q4
A coaxial cable consists of conductors that have:
Explanation
The term coaxial means that the conductors share the same axis. A coaxial cable typically has a central conductor surrounded by insulation, a metallic shield, and an outer protective jacket.
Q5
The area covered by a satellite radio beam is called its:
Explanation
A satellite's footprint is the geographical area on Earth's surface where its transmitted signal can be received effectively.
Q6
The amount of uncertainty associated with a system or symbol is called:
Explanation
In information theory, entropy measures the uncertainty or randomness associated with information. Higher entropy generally means greater uncertainty about the outcome of a symbol or event.
Q7
Buffering is the process of:
Explanation
Buffering temporarily stores data in a memory area called a buffer. It helps manage differences in the speeds at which devices produce and process data.
