The clock speed is the speed at which a microprocessor is able to execute instructions. A bus is the term used to describe the set of conductors that transmit data or that address or control information to the microprocessor's different elements. Most microprocessors consist of three different buses, which include the data bus, the address bus, and the control bus.

Microprocessors can be based on the number of bits the processor's internal data bus or the number of bits that it can process at a time which is known as the word length. Based on its word length, a microprocessor can be classified as 8-bit, bit, bit, and bit.

RISC microprocessors are more general use than those that have a more specific set of instructions. The execution of instructions in a processor requires a special circuit to load and process data. Because RISC microprocessors have fewer instructions, they have simpler circuits, which means they operate faster. Additionally, RISC microprocessors have more registers, use more RAM, and use a fixed number of clock cycles to execute one instruction.

Their purpose is to reduce the number of instructions for each program. The number of cycles per instruction is ignored.

Because complex instructions are made directly into the hardware, CISC microprocessors are more complex and slower. Communication: Microprocessors are being used in a wide range of communication equipments. In telephone industry, these are used in digital telephone sets. Telephone exchanges and modem etc. The use of microprocessor in television, satellite communication have made teleconferencing possible. Railway reservation and air reservation system also uses this technology.
