Computer Networks Questions

Multiple choice

It is an open standard technology that enables you to build wireless community between the laptops and local area network. Name the technology?

  1. LAN

  2. Wi-Fi

  3. Configure

  4. Booting

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Wi-Fi (Wireless Fidelity) is the technology that allows wireless connections between devices like laptops and local area networks. It uses radio waves to provide wireless high-speed Internet and network connections. LAN is wired, while 'Configure' and 'Booting' are processes, not technologies.

Multiple choice

Multiplexer is also known as

  1. data selector

  2. data distributor

  3. decoder

  4. encoder
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A multiplexer is a digital circuit that selects one of several input signals and forwards it to a single output. It is commonly called a data selector because it selects which data input to transmit. Data distributor, decoder, and encoder are different circuit functions.

Multiple choice

Protocols are

  1. agreement on how to communicate between two systems

  2. logical communication channels used for transferring data

  3. physical communication channels used for transferring data

  4. none of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Protocols define standardized rules and conventions that enable two or more systems to communicate with each other. They specify format, timing, sequencing, and error control. Logical (B) and physical (C) channels are the media used, not the protocols themselves.

Multiple choice

TELNET means

  1. Telephone network

  2. Virtual Telephone Network

  3. Telescope Network

  4. Terminal Network
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

TELNET (TELetype NETwork) is a network protocol that allows a user to access a remote terminal over a network. It provides terminal emulation, enabling a local terminal to behave as if directly connected to the remote system. The name derives from teletype machines, not telephones.

Multiple choice

Which of the following networks was a defence network?

  1. ARCNET

  2. ARPANET

  3. APRANET

  4. X.25
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

ARPANET (Advanced Research Projects Agency Network) was developed by the US Department of Defense and was the first operational packet-switching network, serving as the foundation for what later became the modern Internet.

Multiple choice

Which of the following technologies interconnect different networks and determine the optimal path for a packet of data to traverse through a interconnected series of networks to reach its destination?

  1. Remote bridge

  2. Lattice flow

  3. Gateway

  4. Brouter

  5. Routers
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

It interconnects different networks and determine the optimal path for a packet of data to traverse through a interconnected series of networks to reach its destination.

Multiple choice

In which of the following networking configuration, ordinary application programs deals immediately with networking instead of indirectly with networking through application support?

  1. Simple networking

  2. Separated networking

  3. Shared networking

  4. Direct networking

  5. Sub networking technology
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In this networking configuration, ordinary application programs deals immediately with networking instead of indirectly with networking through application support.
