Bus cycle refers to the process of transferring data between the CPU and memory or peripherals, while instruction cycle refers to the series of steps that the CPU goes through to fetch, decode, and execute instructions. In other words, bus cycle involves the movement of data, while instruction cycle involves the actual execution of instructions.

What is a bus that runs back and forth?

A shuttle bus is a type of bus that runs back and forth along a specific route, such as between an airport and a hotel or between different areas within a campus or a large facility.


Why does your friend appear to be at rest though the bus is moving?

Your friend appears to be at rest because they are in the same reference frame as the bus. Since they are moving at the same speed and direction as the bus, there is no relative motion between them and the bus, making it seem like they are at rest.


Difference between front side bus and back side bus?

The front side bus refers to the communication pathway between the CPU and other components like RAM, while the back side bus is a secondary pathway used for communication between the CPU and other components like the chipset or I/O devices. The front side bus is typically faster and carries more critical data, while the back side bus is used for less critical communication.


How many bits per second can be transferred if the bus frequency is one gig Hz?

If the bus frequency is one gigahertz (GHz), it means it can transmit one billion cycles per second. Considering each cycle can transfer one bit, the bus can transfer one billion bits per second or 1 gigabit per second (Gbps).


What are difference between bus reactor and line reactor?

Bus reactors are connected to the busbars of a power system to limit fault currents and improve system stability. Line reactors are connected in series with the power line to limit current surges, reduce harmonics, and provide overvoltage protection. Both types of reactors help improve the performance and reliability of the power system, but they are installed at different locations within the system.
