What is a hard drive in simple terms?

A hard disk drive (HDD) is a non-volatile computer storage device containing magnetic disks or platters rotating at high speeds. It is a secondary storage device used to store data permanently, random access memory (RAM) being the primary memory device. A hard disk drive is also known as a hard drive.

Why is it called a hard drive?

The data is stored on the hard drive magnetically, so it stays on the drive even after the power supply is turned off. The term “hard drive” is actually short for “hard disk drive.” The term “hard disk” refers to the actual disks inside the drive.

What is a hard drive in a computer?

A computer hard drive (or a hard disk or HDD) is one kind of technology that stores the operating system, applications, and data files such a documents, pictures and music that your computer uses. The rest of the components in your computer work together to show you the applications and files stored on your hard drive.

What is the difference between SSD and hard disk?

Comparing SSDs and HDDs HDDs are a legacy storage technology that use spinning disks to read/write data. SSDs are faster and more power efficient than HDDs. HDDs are priced lower, but SSD prices are dropping.

How do hard drives work?

The hard drive contains a spinning platter with a thin magnetic coating. A “head” moves over the platter, writing 0’s and 1’s as tiny areas of magnetic North or South on the platter. To read the data back, the head goes to the same spot, notices the North and South spots flying by, and so deduces the stored 0’s and 1’s.

Where is hard drive in computer?

Locate the hard drive inside the computer case. The hard drive is a rectangular metal box the size and width of a small book. By convention, most computers locate the hard drive near the front of the case, near other drives (like your optical drive).

  • Is a hard drive a storage or processing device?

    A hard drive, also known as a hard disk drive, is a storage device used on many computers. A hard drive consists of spinning platters that store digital information read by fast-moving read/write heads. Hard drives are the computer component most prone to failure but offer high performance for the price.

    Is a hard disk and a hard drive the same?

    A hard disk drive — often shortened to hard drive — and hard disk are not the same things, but they are packaged as a unit and either term can refer to the whole unit. In a computer, an HDD is commonly found in the drive bay and is connected to the motherboard via an ATA, SATA or SCSI cable.

    What are examples for hard drive?

    Internal hard disks reside in a drive bay, connected to the motherboard using an ATA, SCSI, or SATA cable. They are powered by a connection to the computer’s PSU (power supply unit). Examples of data stored on a computer’s hard drive include the operating system, installed software, and the user’s personal files.
