11. The computer

12. information cycle:
input
process
output
store

13. Classifying computers
Computers can be classified
in terms of their purpose
how ‘powerful’ they are
their size

14. Dedicated versus general-purpose computers
Dedicated devices
designed to perform just one specific task

15. Dedicated versus general-purpose computers
allow us to load programs (software) to perform a wide variety of tasks.

16. Processing power and usage

17. Portability Laptop / Notebook / Ultrabook / Netbook
Laptop / Notebook – describes same types of portable computers
Netbook – cheap, low-powered, no DVD/CD, lower screen resolution
Ultrabooks – lighter/thinner, but still as powerful as entry-level PC

18. Portability Tablets Consumer tablet: Touch / pen sensitive monitor
User interacts directly with screen
Special operating systems
Long battery life
3G/wireless connectivity
Traditional tablet:
Reversible screen / normal keyboard
Work as notebook / tablet

19. Portability Smartphones All smartphones have: Operating system
‘Large’ colour screens
Data modem: 3G, HSDPA, 4G
GPS sensor
Cameras

21. Protecting your information

22. the theft of hardware is not just about the cost of replacing the hardware
Information that you do not have a copy of
Information might be private or sensitive
Information stored on portable devices

23. Hardware theft and protection
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.

24. Protection against power failure
Uninterruptible Power Supplies
connected to the mains
immediately provides power to the computer(s) connected to it as soon as the power goes out

25. Protection against power failure
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.

26. Protection against power failure
Power settings
Set to ‘sleep’ or hibernate (portable computers) when it has not been used for a period of time.
Set brightness of the screen to reduce the power consumption.
Choose a balance between power consumption and performance.
