Internal & External Storage

DIFFERENCE BETWEEN BOTH:

Your computer uses two different types of storage devices: internal memory and external memory. While both types save and access your data files, they do so in different ways. Internal and external storage devices have very different physical and operational characteristics.(science.opposingviews.com)

The two broad categories of computer memory are random-access memory and read-only memory. When you run a program, it stores its processes in RAM. RAM is volatile, which means if you close the program without saving a file, you lose whatever changes you made since the last time you saved the file. If you saved the file, the computer commits the data to ROM, which is not volatile, so even if you turn off the computer, you will not lose the data. Internal memory consists of both RAM and ROM, while external devices use only ROM.(science.opposingviews.com)

Internal memory is limited in its versatility. Generally, once it’s connected to a computer, that’s where it stays. You cannot remove internal memory without taking your computer apart. However, as you may expect, you don’t have to keep external memory attached to one computer. External storage devices are designed so you can easily share these devices between computers. (science.opposingviews.com)200526537-001External storage is outside the computer enclosure. Internal is inside. External storage sometimes needs an additional power source, internal is connected to the computer power supply. External storage can use the same sort of connection (SATA) as internal, but it frequently just uses USB as that is more common. USB can be slower. FireWire and other approaches can be used.(science.opposingviews.com)

External storage sometimes needs a drive controller while internal operates using components on the computer.

Computer storage drives come in three main types: internal,external, and universal serial bus(USB) drives. However, each of the three drive types has individual differences of its own. This guide will explain the differences in each of the drive types as well as the particulars of external, internal, and USB drives. The guide will discuss how each of the different drives can be attached to a personal computer (PC) and how the individual drive types may be used for different tasks. In addition, drive specifications will be discussed, as will desktop drives, laptop drives, and USB memory sticks.

Storage drives are common computer components and can be found easily at local retail outlets. Computer stores, office supply stores, electronic retailers, and even some large discount stores offer external, internal, and USB storage drives. (ebay.com)
