Question

write any three difference between pendrive & Hard disk​

Answer 1

Answer:

definition of a pen drive is small storage device shaped like a pen with built-in data storage that connects to a computer by a USB port. An example of a pen drive is a pen with a hidden USB port for saving data.

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

Hard Disk

is a Primary Storage and is based of Magnetic Plate and stronger, and long life media. There is Platter in Hard Disk (Magnetic Platter).

Users are usually confused between using a flash drive and a hard drive. Both can expand the disc space of a personal computer, but these two have different capacities and file storage systems.

A flash drive and a hard drive can be both portable and are generally plug-and-play. A flash drive, however, has smaller capacity compared to a hard drive. Thus, a portable hard drive (also called external hard drive) is capable of storing almost all of the personal computer’s content for backup. Hard drives are more preferred by consumers today as they can serve as protection for the files amidst the vast expanse of Trojan horses, spyware, and viruses that may corrupt the files in a personal computer.

The term “flash” drive. They are handier compared to hard drives which are fairly heavy and palm-sized. Flash drives are also virtually weightless and can retain memory without a source of power. They can help greatly in the extension of the laptop’s battery when users work outside their homes or offices.

The two memory devices operate with different processes. A hard drive consists of spinning platters along with a roving head which can read data that are magnetically imprinted on the platters. On the other hand, flash disks store data without moving parts. This makes them less likely to fail as they generate very little heat. The memory storage works with an electronic process where “cells” of memory chips are flashed in order for the data to be cleared or changed. The reduced energy use and heat generation makes flash drives more durable than hard drives.

While flash drives are more convenient and very handy to personal computers with limited power supply, hard drives can also give a wide range of benifits to users. Aside from being capable of storing files with larger sizes, hard drives can also come with cheaper price tags. A hard drive with a 2 terabyte memory capacity can be purchased for at least $75, while a flash drive with the maximum memory capacity can be bought with the price doubled. If the ratio of the price and memory is considered, the user’s better bet can be the hard drive.
