What transmission method is used in the internal circuitry of computers with Integrated Circuits?

In internal circuitry of computers that use Integrated Circuits (ICs), parallel transmission is the correct method. This technique allows multiple bits of data to be transmitted simultaneously across multiple channels or wires within the circuit. This enhances data transfer rates significantly, as several bits can be sent in a single clock cycle rather than waiting to send one bit at a time, which is the case with serial transmission. This advantage is crucial for the efficient operation of processors and other components where speed is essential.

The parallel transmission method is particularly beneficial in short-distance contexts, such as within computer processors, where the circuit traces are close together. This reduces issues like signal degradation and timing mismatches that can occur in longer distances typical of serial communication.

Other methods like serial transmission only send one bit at a time, making it slower for internal communications but more suitable for long-distance transmissions where reduced physical wiring is preferable. Vector transmission pertains more to data representation rather than transmission method, and wired transmission is a broad category that doesn’t specify whether the communication is done serially or in parallel.
