1- Moore\'s law: how did computer speeds and storage evolve through the years?

2- How do hard disks work and how is data retrieved and stored on disks?

3- Illustrate with graphics and images how the bootup process happen?

4- Read about a data (security) breach story and report about it.

Solution

Data storage devices have evolved drastically from being large trunks with the capacity to hold a few kilobytes of data, to microchips able to hold a few gigabytes of data.

In this article we will be looking at how these storage devices, both Hard Disks and Flash Storage Devices, have become what they are at present.

Cloud Storage
This is another great leap in the storage technology. To give a brief introduction, all data is stored in a storage called “The Cloud” which can be accessed from any device and from anywhere using the internet.

How a hard drive works

In your computer\'s hard drive, there aren\'t really any iron nails. There\'s just a large shiny, circular \"plate\" of magnetic material called a platter, divided into billions of tiny areas. Each one of those areas can be independently magnetized (to store a 1) or demagnetized (to store a 0). Magnetism is used in computer storage because it goes on storing information even when the power is switched off. If you magnetize a nail, it stays magnetized until you demagnetize it. In much the same way, the computerized information (or data) stored in your PC hard drive or iPod stays there even when you switch the power off.
