CLASSIFYING COMPUTERS

13

Computers can be classified

in terms of their purpose

how ‘powerful’ they are

their size

DEDICATED VERSUS GENERAL-PURPOSE COMPUTERS

14

Dedicated devices

designed to perform just one specific task

DEDICATED VERSUS GENERAL-PURPOSE COMPUTERS

15

General-purpose computers

allow us to load programs (software) to perform a wide variety of tasks.

Laptop / Notebook / Ultrabook / Netbook

Laptop / Notebook – describes

same types of portable

computers

Netbook – cheap, low-powered,

no DVD/CD, lower screen

but still as powerful as entry-

level PC

THE THEFT OF HARDWARE IS NOT JUST ABOUT THE COST OF REPLACING THE HARDWARE

22

• Information that you do not have a copy of

• Information might be private or sensitive

• Information stored on portable devices

HARDWARE THEFT AND PROTECTION

23

Anti-theft strategies for hardware:

• Use devices such as cable locks

• Chain equipment to a fairly solid object

• Use lockable cabinets (with ventilation) in which to place the system units (‘boxes’) of a desktop computer or server.

• Make use of motion sensors with an alarm which detect when a computer has been moved.

PROTECTION AGAINST POWER FAILURE

24

Uninterruptible Power Supplies

• connected to the mains

• immediately provides power to the computer(s) connected to it as soon as the power goes out

PROTECTION AGAINST POWER FAILURE

25

Power settings

Portable computers and devices can be used without connecting them to a power outlet.

Run on battery power.

Desktops - we also need to save as much power as possible.

PROTECTION AGAINST POWER FAILURE

26

Power settings

Set to ‘sleep’ or hibernate (portable computers) when it has not been used for a period of time.

Choose a balance between power consumption and performance.

Set brightness of the screen to reduce the power consumption.
