What is RAM used for in a computer?
RAM (Random Access Memory) is the hardware in a computing device where the operating system (OS), application programs and data in current use are kept so they can be quickly reached by the device’s processor. RAM is the main memory in a computer.
What is a computer system Ignou?
So a computer can be considered as a calculating device that can perform arithmetic operations at a high speed but more accurately. Computer is a digital electronic storage device, which accepts data and set of instructions, manipulates it, and retrieves the information at very high speed.
What is a motherboard in a computer?
A motherboard is the main printed circuit board (PCB) in a computer. The motherboard is a computer’s central communications backbone connectivity point, through which all components and external peripherals connect. Motherboards can be found in virtually all computers, especially desktop and laptop PCs.
How does computer is able to execute an instruction Ignou?
The CPU fetches an instruction from the memory at a time and executes it. thus, the instructions are executed sequentially which is a slow process.
How does computer is able to execute an instruction?
The CPU executes a program that is stored as a sequence of machine language instructions in main memory. It does this by repeatedly reading, or fetching, an instruction from memory and then carrying out, or executing, that instruction.
What is motherboard and types?
The most common motherboard form factor is ATX. The different types of ATX are known as micro-ATX (sometimes shown as µATX, mini-ATX, FlexATX, EATX, WATX, nano-ATX, pico-ATX, and mobileATX). A smaller form factor is ITX, which comes in mini-ITX, nano-ITX, and pico-ITX sizes.
What are the 2 types of RAM?
There are two main types of RAM: Dynamic RAM (DRAM) and Static RAM (SRAM).
- DRAM (pronounced DEE-RAM), is widely used as a computer’s main memory.
- SRAM (pronounced ES-RAM) is made up of four to six transistors.
What are the steps in instruction execution?
The Instruction Execution Cycle of the CPU consists of the following 4 steps:
- The instruction fetch step/phase.
- The instruction decode step/phase.
- The operand fetch step/phase.
- The instruction execute step/phase.
What are the two steps in instruction processing?
The cycle consists of the following steps: – Fetch instruction: Like the name stated in this process the cpu fetches the instruction from the memory. The PC get loaded with the address of the instruction. – Decode: the instruction: In this process the instruction gets decoded by the processor.
What are the five execution steps?
Those stages are, Fetch, Decode, Execute, Memory, and Write. The simplicity of operations performed allows every instruction to be completed in one processor cycle.
