I/O Interface in Computer Organization

I/O interface refers to the process of transferring data from internal storage to external I/O devices. Peripherals linked to any computer system interface with the CPU via particular communication lines. These links are useful to bridge the gap between the CPU and the peripheral. Interface units are specific hardware components that sit between the CPU… Continue Reading »

RAM and ROM in Computer Organization

In this tutorial, we are going to learn about RAM and ROM in computer organization. What Are RAM and ROM in Computer Organization RAM (RANDOM ACCESS MEMORY) RAM (Random Access Memory) is the internal memory of the CPU, which stores data, programs, and program results. It’s a read-only memory that stores data until the machine… Continue Reading »

Cache Memory in Computer Organization

Cache memory in computer organization is a speedier and smaller chunk of memory with access times that are as close as registers. Cache memory has a shorter access time than primary memory in a memory hierarchy. Because cache memory is typically relatively little, it basically acts as a buffer. The data or contents of the… Continue Reading »

Memory Hierarchy in Computer Organization

Memory Hierarchy is a feature in computer system design that helps to organize memory. This was created using a programming technique called locality of references. This tutorial will help you to learn more about memory hierarchy. Types of Memory Hierarchy Design : There are two types of memory hierarchies in this design:Main Memory is the… Continue Reading »

Instruction Format in Computer Organization

In this tutorial we are going to learn about instruction format in computer organization. What is Instruction format : In terms of its basic pieces, instruction format explains the internal structures (layout design) of the bits of an instruction.An opcode must be there in an Instruction format, and the address is reliant on the availability… Continue Reading »

Types of Instructions in Computer Organization

In this tutorial, we are going to learn about the various types of instructions (logical, arithmetic, branch) in computer organization. Logical Instructions in Computer Organization: A microprocessor’s logical instructions are simply those that carry out simple logical operations like OR, AND, XOR, and so on. The accumulator register is always the destination operand for instructions… Continue Reading »

RISC and CISC in Computer Organization

The Central Processing Unit (CPU) architecture operates the capacity to function from “Instruction Set Architecture” to where it was designed. Reduced instruction set computing (RISC) and Complex instruction set computing (CISC) are basically two architectural designs for CPUs. Intel uses Complex Instruction Set Computer (CISC), while Apple uses Reduced Instruction Set Computer (RISC). RISC (Reduced… Continue Reading »

Addressing Modes in Computer Organization

In this tutorial, we are going to learn about Addressing Modes in Computer Organization. The phrase addressing modes refers to the manner we state an instruction’s operand. Before the execution of the operand, the addressing mode provides a rule for interpreting or altering the address field of the instruction. Types of Addressing Modes in Computer… Continue Reading »

Instructions In Computer Organization

Here, we are going to learn about instructions in computer organization. Computer instructions are a set of machine language instructions that a certain processor understands and executes. A computer executes tasks based on the commands it receives. An instruction is made up of groups that make up a field. Following are some of the fields:… Continue Reading »

Basic Components of Computer Organization

In this tutorial, we are going to learn about basic components of computer organization. A computer is a fast electronic calculating machine that accepts (data) digitized input information, processes it according to a list of internally stored instructions, and outputs the results. Programs are lists of instructions, while memory is internal storage. The way a… Continue Reading »
