MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -The external system bus architecture is created using from architecture: Pascal.

Detailed explanation-2: -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.

Detailed explanation-3: -In computer architecture, a control bus is part of the system bus and is used by CPUs for communicating with other devices within the computer.

Detailed explanation-4: -The system bus is a pathway composed of cables and connectors used to carry data between a computer microprocessor and the main memory. The bus provides a communication path for the data and control signals moving between the major components of the computer system.

Detailed explanation-5: -A processor register (CPU register) is one of a small set of data holding places that are part of the computer processor. A register may hold an instruction, a storage address, or any kind of data (such as a bit sequence or individual characters). Some instructions specify registers as part of the instruction.
