Correct option is A
Manchester coding is a line code where each bit of data is represented by two signal changes:
· A high-to-low transition represents a logical
0.
· A low-to-high transition represents a logical
1.
Since each bit requires
two signal transitions, the bit rate is
half the baud rate.

Circuit Switching vs. Packet Switching:
· Circuit Switching establishes a dedicated path between the sender and receiver, ensuring consistent latency but wasting resources if the connection is idle.
· Packet Switching divides data into packets that can take different routes, optimizing bandwidth usage but introducing delay variability.
2.
Manchester Coding Characteristics:
· Combines clock and data into a single signal for synchronization.
· Provides good noise immunity.
· Used in Ethernet standards such as 10BASE-T.
3.
Key Differences:
·
Bit Rate: Number of data bits transmitted per second.
·
Baud Rate: Number of signal changes or symbols per second.
Additional Knowledge
·
Packet Switching Drawbacks: Reordering and delay (jitter) issues can occur, especially in real-time applications like video conferencing.
·
Circuit Switching Advantage: Consistent delay and guaranteed bandwidth, making it suitable for applications like traditional telephony.
