What is hard disk with example?

A hard disk drive (sometimes abbreviated as a hard drive, HD, or HDD) is a non-volatile data storage device. It is usually installed internally in a computer, attached directly to the disk controller of the computer’s motherboard. It contains one or more platters, housed inside of an air-sealed casing.

What is RAM and ROM used for?

RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.

What type of memory is hard disk?

A hard disk drive (HDD), hard disk, hard drive, or fixed disk is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage and one or more rigid rapidly rotating platters coated with magnetic material.

Can we use hard disk as RAM?

Windows can allocate memory to a hard drive as well as to a RAM module. … Windows uses virtual memory to store data for programs that are open but not in use. To boost the amount of virtual memory in your computer, connect an external hard drive to your computer and set Windows to use it as virtual memory.

Is ROM or RAM faster?

ROM memory is used to store permanent information, which is non-erasable. The access speed of RAM is faster. Its speed is slower in comparison with RAM. Therefore, ROM can’t boost up the processor speed.

Is SSD RAM or ROM?

SSDs use a special type of memory circuitry called non-volatile RAM (NVRAM) to store data, so everything stays in place even when the computer is turned off. Even though SSDs use memory chips instead of a mechanical platter that has to be read sequentially, they’re still slower than the computer’s RAM.

Why is RAM faster?

Generally, the faster the RAM, the faster the processing speed. With faster RAM, you increase the speed at which memory transfers information to other components. … The speed of your processor and the bus speed of the system motherboard are the limiting factors on the speed of RAM installed in your system.

Which memory is the fastest?

Fastest memory is cache memory.Registers are temporary memory units that store data and are located in the processor, instead of in RAM, so data can be accessed and stored faster.More items…

Is ROM main memory?

Computer memory is of two basic type – Primary memory(RAM and ROM) and Secondary memory(hard drive,CD,etc.).
