CIE A2 Chpater 16 - Network

Which of the following is a characteristic of circuit switching?

Answer explanation

Answer: A dedicated communication path is established before transmission.

Circuit switching establishes a dedicated path for communication before data transfer, ensuring a constant connection.

What is established before transmission in circuit switching?

• A) A dedicated communication path

• B) A random communication path

• C) No communication path

• D) A temporary communication path

In packet switching, packets contain:

• Headers and payload

• Only headers

• Only payload

• Neither headers nor payload

Explain the components of a packet in packet switching, including the header and data body.

• A packet consists of a header and a data body.

• A packet consists of a footer and a data body.

• A packet consists of a header and a footer.

• A packet consists of a data body only.

The key difference between circuit switching and packet switching is:

• Circuit switching establishes a dedicated path, while packet switching does not.

• Packet switching establishes a dedicated path, while circuit switching does not.

• Both establish a dedicated path.

• Neither establish a dedicated path.

What is a key difference between circuit switching and packet switching?

• Circuit switching requires a dedicated path, while packet switching does not.

• Packet switching requires a dedicated path, while circuit switching does not.

• Both require a dedicated path.

• Neither requires a dedicated path.

Fill in the blank: Circuit switching maintains a continuous connection, while packet switching divides data into ______ sent independently.

• packets

• streams

• circuits

• channels

What are the two types of packet-switching services?

• Virtual Circuit and Datagram

• Circuit Switching and Message Switching

• Frame Relay and ATM

• TCP and UDP

Explain the difference between connectionless service and connection-oriented service.

• Connectionless service does not require a dedicated path, while connection-oriented service does.

• Connection-oriented service is faster than connectionless service.

• Connectionless service is more reliable than connection-oriented service.

• Connection-oriented service does not require error checking.

A protocol is a set of rules or procedures for transmitting data between electronic devices. What is a protocol?

• A type of software

• A set of rules for data transmission

• A hardware device

• A programming language
