What are the function of external bus in computer?
An external bus primarily enables connecting peripherals and all external devices to a computer. These devices can include storage, monitors, keyboard, mouse and more. Typically, an external bus is composed of electrical circuits that connect and transmit data between the computer and the external device.
What do you mean by bus?
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 may be parallel or serial. Parallel buses transmit data across multiple wires.
What is a bus protocol?
The essence of any bus is the set of rules by which data moves between devices. This set of rules is called a “protocol.” This chapter describes the basic protocol that controls the transfer of data between devices on a PCI bus.
Why is a bus protocol important?
The bus protocol is set of rules governing how the bus works properly. If you don’t use to proper bus protocol, you may end up offending a fellow rider.
What is difference between bus and port?
A computer port is a slot or a connection point on a computer, similar to a plug point, where a device can be connected. The system bus, also called the memory bus, makes a connection between the CPU and the main memory of the computer that resides on the motherboard.
What is a common bus?
The basic computer has eight registers, a memory unit, and a control unit . Paths must be provided to transfer information from one register to another and between memory and registers. A more efficient scheme for transferring information in a system with many registers is to use a common bus. …
What do you mean by register transfer?
The term Register Transfer refers to the availability of hardware logic circuits that can perform a given micro-operation and transfer the result of the operation to the same or another register. Data Transfer from one register to another register is represented in symbolic form by means of replacement operator.
How many multiplexer are there in the bus?
The bus consists of 4×1 multiplexers with 4 inputs and 1 output and 4 registers with bits numbered 0 to 3. There are 2 select inputs S0 and S1 which are connected to the select inputs of the multiplexers.
What is a bus multiplexer?
A type of bus structure in which the number of signal lines comprising the bus is less than the number of bits of data, address, and/or control information being transferred between elements of the system.
How many multiplexers are needed?
answer is B) 32 mux are required .
