But it could store data up to 3.14MB only. What is Hardware Know what the CPU is What is a Graphic Cardīefore the use of Hard Disk, floppy disk was used to store information in the computer. Most Hard Disk ranges from 5400 RPM to 7200 RPM. This means how many rounds the platter took in a minute. Its speed is measured in RPM (Revolution Per Minute). The faster the spindle rotates the platter, the faster the data will be stored in the Hard Disk. Its job is to read data and write data from platter. When the platter starts rotating, a Read / Write arm in the Hard Disk moves it from right to left. There are many tracks and sectors present in these platters and it rotates through the spindle. The hard disk consists of one or more circular rotating disks to store the data.Įach platter has a very thin strip, which is made using magnetic material. That is why it is also called Electro-mechanical data storage device. Hard Disk uses magnetic storage to store and retrieve digital information. It exists inside a computer case (CPU) and is connected to the computer motherboard using data cables (PATA, SCSI, SATA). Hard Disk is also called Secondary Storage Device.
That is, the computer keeps the data safe even after power off. They are called non-volatile device, which can store any type of data in the computer for a long time. Hard disk work is to permanently store and retrieve computer data. Hard Disk, also called Hard Disk Drive (HDD), is a non-volatile memory hardware device. Hard Disk Definition, functions and types Table of contents What is Hard Disk So let’s first know, what is called a hard disk and then we will talk about other aspects of it. In this post we will tell you what is a hard disk in a computer? In which you will get to know a lot about Hard Disk. Hard Disk is seen as an important component of a computer because no computer will work without it. Whereas the primary memory device (RAM) serves to process the computer’s programs. In which Hard Disk is a secondary memory device. Just as a library is required to handle books in the library, the same computer also needs such a place in which it can store digital data.Ĭomputers use two types of storage devices to store and process digital content (Document, Image, Videos, Software, Operating system, Program).
In this article, you will know what is Hard Disk and what are the types of it? Hard disks are also often called Disk drive or “Hard Disk Drive (HDD)”.
