Yr 12 CS - Data Transmission

Which of the following statements correctly describes serial and parallel transmission?

• Serial transmission sends data one bit at a time, while parallel transmission sends multiple bits simultaneously.

• Serial transmission sends multiple bits simultaneously, while parallel transmission sends data one bit at a time.

• Both serial and parallel transmission send data one bit at a time.

• Both serial and parallel transmission send multiple bits simultaneously.

Simplex, half duplex, and full duplex are types of:

• Transmission methods

• Network topologies

• Data encryption techniques

• Error correction codes

The need for multiplexing and switching is to:

• Increase the speed of individual data streams

• Allow multiple signals to share the same communication channel efficiently

• Reduce the number of devices in a network

• Eliminate the need for network protocols

Describe, using appropriate network protocols, such as TCP/IP, the typical contents of a packet.

• A packet typically contains a header, payload, and trailer.

• A packet only contains a header.

• A packet only contains a payload.

• A packet contains only a trailer.

Network collision occurs when two devices send data on the same network segment simultaneously. What is the process called that detects these collisions and how are they typically handled?

• Collision detection; devices stop transmitting and resend after a random delay

• Packet switching; devices ignore the collision

• Error correction; devices automatically fix the data

• Load balancing; devices reroute the data

Methods of routing traffic on a network include:

• Static routing and dynamic routing

• Only static routing

• Only dynamic routing

• Manual switching

Fill in the blank: Serial Transmission is when data is sent _______ at a time along the same data line/single wire from source to destination.

• one bit

• two bytes

• one word

• four bits

Which of the following best describes serial data transmission?

• Data is sent in parallel along multiple wires

• Data is sent one bit at a time along the same data line

• Data is sent wirelessly

• Data is sent in packets of 8 bits at a time

Refer to the diagram showing the binary sequence '0 0 1 0 1 1 0 1' being sent along a wire. What type of data transmission is being illustrated?

• Serial data transmission

• Parallel data transmission

• Analog data transmission

• Wireless data transmission

Which type of data transmission can travel longer distances?

• Serial

• Parallel
