Final answer:
A parallel bus is a type of data transmission used in computer systems to send multiple bits simultaneously across multiple lines. It allows for faster data transfer compared to a serial bus.
Step-by-step explanation:
The correct answer is option Computers and Technology. Parallel bus is a term commonly used in computer architecture and refers to a type of data transmission where multiple bits are sent simultaneously across multiple wires or lines.
It is often used in computer systems, such as in the parallel ATA (PATA) interface for connecting hard drives to a computer.
An example of parallel bus transmission is the sending of data from the computer's memory to the graphics card for display. The parallel bus allows for faster data transfer compared to a serial bus, which transmits one bit at a time.
Overall, in the context of data transmission and computer architecture, a parallel bus is an important concept to understand and is commonly used in various computer systems.
The correct answer is option transmission along power lines. A parallel bus transmits data by sending multiple bits simultaneously across multiple channels or wires.
This is similar to how voltage is delivered from an electrical power plant for transmission along power lines; multiple lines carry the power to ensure there is enough capacity for the electricity needed by the end-users.
In computers, the use of a parallel bus increases the data transmission rate because more information is being transferred at the same time, as opposed to a serial bus, which transmits data one bit at a time.
In terms of electrical circuitry, when devices are connected in parallel, the overall current and power capabilities are higher compared to a series connection.
Similarly, in a capacitor operating with a parallel connection, the effective plate area is larger, which increases the total capacitance, improving its ability to store charge. This concept broadly relates to the increased bandwidth of a parallel data bus.
