What are the four categories of computer instructions?

What are the four categories of computer instructions?

A set of instructions is said to be complete if the computer includes a sufficient number of instructions in each of the following categories:

• Arithmetic, logical and shift instructions.
• A set of instructions for moving information to and from memory and processor registers.

What are specific instructions given to a computer?

A set of instructions that directs a computer’s hardware to perform a task is called a program, or software program. The two main types of software are system software and application software.

What are the possible states that define an instruction execution?

Instruction address calculation (iac): Determine the address of the next instruction to be executed. Instruction fetch (if): Read instruction from its memory location into the processor.

What are the main structural components of a computer?

The four main structural elements of a computer are as follows:

• Processor.
• Main memory.
• I/O Modules.
• System Bus.

What are the different types of instructions?

Depending on operation they perform, all instructions are divided in several groups:

• Arithmetic Instructions.
• Branch Instructions.
• Data Transfer Instructions.
• Logic Instructions.
• Bit-oriented Instructions.

What are the different types of instructions in computer architecture?

A computer must have the following types of instructions:

• Data transfer instructions.
• Data manipulation instructions.
• Program sequencing and control instructions.
• Input and output instructions.

What is instruction and types of instruction?

A computer must have the following types of instructions: Data transfer instructions. Data manipulation instructions. Program sequencing and control instructions. Input and output instructions.

What are the types of instructions in computer and give example for each one?

Arithmetic, logical and shift instructions (and, add, complement, circulate left, right, etc) To move information to and from memory (store the accumulator, load the accumulator) Program control instructions with status conditions (branch, skip) Input output instructions (input character, output character)

How is execution of an instruction done?

The instruction execution takes place in the CPU registers. The CPU reads (fetches) instructions (codes) from the memory one at a time, and executes or performs the operation specified by this. Instruction fetch involves reading of an instruction from a memory location to the CPU register.

What is meant by instruction execution as applied in processors?

instruction execution – (computer science) the process of carrying out an instruction by a computer. execution.

What are the four main function of a computer?

Data processing. Information output. Data and information storage.
