Computer Science for IGCSE & O level - Data Transmission (Section 3 - No. 41)

What is a possible disadvantage of implementing a checksum in data transmission?

Increased processing overhead for both the sender and the receiver.

It is not effective in detecting errors.

It increases data transmission speed.

It simplifies data compression.

Checksum calculations require extra processing power and time at both the sending and receiving ends, adding overhead to data transfer.
