What is TCP in network communication?

• Transmission Control Protocol

• Transfer Control Protocol

• Communication Transfer Protocol

• Connection Transmission Protocol

Answer explanation

TCP stands for Transmission Control Protocol, which is a fundamental protocol in network communication that ensures reliable data transmission. The correct choice is 'Transmission Control Protocol', not 'Connection Transmission Protocol'.

What does the network protocol determine?

• Transmission speed

• Type of transmission

• Error checking method

• All of the above

Answer explanation

The network protocol determines various aspects of data transmission, including transmission speed, type of transmission, and error checking methods. Therefore, the correct answer is 'All of the above'.

Which of the following is a synchronous network protocol?

• Email

• Instant messaging

• Bulletin board

• Control panel

Answer explanation

Instant messaging is a synchronous network protocol as it allows real-time communication between users. In contrast, email and bulletin boards are asynchronous, and a control panel does not fit the definition of a communication protocol.

Which of the following is an asynchronous network protocol?

• Direct call

• Instant messaging

• Email

• Phone call

Answer explanation

Email is an asynchronous network protocol because it allows users to send and receive messages without both parties being online simultaneously, unlike direct calls, instant messaging, and phone calls which require real-time interaction.

What is the purpose of the handshake in network protocols?

• Disconnect the network

• Establish a connection and exchange messages

• Transfer data faster

• Error checking

Answer explanation

The handshake in network protocols is crucial for establishing a connection and enabling the exchange of messages between devices, ensuring that both parties are ready for communication.

What happens in a synchronous transmission?

• Data is sent at different times

• Data is sent at the same time

• The connection is interrupted

• Transmission fails

Answer explanation

In synchronous transmission, data is sent at the same time, allowing for coordinated communication between sender and receiver. This ensures that both parties are in sync, unlike asynchronous transmission where data is sent at different times.

What happens in asynchronous transmission?

• Data is sent all at once

• Data is sent at different times

• Transmission is delayed

• Transmission fails

Answer explanation

In asynchronous transmission, data is sent at different times rather than all at once. This allows for more flexible communication, as each piece of data can be sent independently, making it suitable for various applications.

In synchronous transmission, which of the following is correct?

• The sender and receiver communicate simultaneously

• The sender and receiver communicate at different times

• Transmission is delayed

• Transmission fails

Answer explanation

In synchronous transmission, the sender and receiver communicate simultaneously, allowing for continuous data flow without delays. This is the key characteristic that distinguishes it from asynchronous transmission.

What is the role of error checking in network protocols?

• To ensure that data is received correctly

• To increase data transmission speed

• To prevent data collisions

• To encrypt data

Answer explanation

Error checking in network protocols is crucial to ensure that data is received correctly. It helps identify and correct errors that may occur during transmission, maintaining data integrity.

Which type of communication can use a handshake in the network?

• Instant messaging

• Email

• Video conference

• File transfer

Answer explanation

Video conferences often require a handshake process to establish a connection between participants, ensuring that both sides are ready to communicate. This is not typically needed in instant messaging, email, or file transfers.
