MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -The internal bus, also known as internal data bus, memory bus, system bus or front-side bus, connects all the internal components of a computer, such as CPU and memory, to the motherboard. Internal data buses are also referred to as local buses, because they are intended to connect to local devices.

Detailed explanation-2: -An address bus consists of the lines that connect between the microprocessor address pins and the address pins of each of the memory chips in the microprocessor system. In anything but a very simple system, the address bus would connect to other units also, but for the moment we will ignore these other connections.

Detailed explanation-3: -A bus is a high-speed internal connection. Buses are used to send control signals and data between the processor and other components. Three types of bus are used. Address bus-carries memory addresses from the processor to other components such as primary storage and input/output devices.

Detailed explanation-4: -A bus is a subsystem that is used to connect computer components and transfer data between them. For example, an internal bus connects computer internals to the motherboard. A “bus topology” or design can also be used in other ways to describe digital connections. A bus may be parallel or serial.

Detailed explanation-5: -The system level bus (as distinct from a CPU’s internal datapath busses) connects the CPU to memory and I/O devices. Typically a system level bus is designed for use as a backplane.
