Storage Devices
A storage device is the system where your computer stores and retrieves your data. Storage devices can be a hard disk drive, DVD, CD drives, Blu-Ray drives or flash drives. A computer can retrieve the data by being “commanded” to retrieve it from the storage area and retrieve it to your RAM. The RAM of the computer is your temporary memory where your data is inputted, and then processed and stored onto a storage device for permanent placement.
There are several different storage devices that can be used to store your data. These are the magnetic storage, optical storage, and solid state storage. According to Parsons and Oja (2014), “a magnetic storage devices stores the data by magnetizing microscopic particles on a disk or tape surface” (p 78). These particles remain on the magnetic disk until it is resaved. This type of drive has a disadvantage because over time the environment can cause the data to corrupt. It is important that when using the magnetic storage that data is re-saved over time to preserve the data.
Parsons & Oja explain that “an optical storage device stores data by using the microscopic light and dark spots on the disc surface. This is possible by the spindle that rotates the disk over a laser lens. The laser directs a beam of light outward the underside of the disk. The dark pits and light lands on the disc surface reflect the light differently. As the lens read the dis, these differences are translated into the 0s and 1s that represent data” (p 81). There is an advantage to using optical storage because it contains a plastic case that protects the drive, and is very durable against environmental causes.
A solid state storage is a device such as a flash drive. Parsons & Oja sta...

... converting text, numbers, sound, photos and video into data that can be processed by digital devices (Parsons & Oja, 2014, p 5). The significance advantage to using Digitization is that this conversion allows it to be compatible with other languages. We can have the data at our fingertips to send through emails, burn onto a disk, create a slideshow, or watch a slideshow on the home theater system.
According to an article, WhatIs.com, retrieved from the web, “Digitizing information makes it easier to preserve, access, and share. For example, an original historical document may only be accessible to people who visit its physical location, but if the document content is digitized, it can be made available to people worldwide”.
Today, the evolution of the digitization era has successfully made it possible for everyone to own a device to communicate with others.
