6. Definition What is a Computer?
A computer is any device that accepts an INPUT, PROCESSES it then produces an OUTPUT.
In pairs, come up with as many digital devices that you think are computers.
Use Communicate Ideas to mind map and add images from the web.

7. Hardware – physical components of a computer system.
Hardware and Software
Hardware – physical components of a computer system.
Software – computer programs including both application software, system software and the computer operating system.

8. Operating Systems

9. What is a operating system?
Unix/Linux
Mac OS
Android
Complete part 1 of the worksheet – matching up the operating systems.
Windows
Blackberry

10. What is an operating system?
The software that communicates with the hardware and allows programs to run.
All computers, smartphones and tablets have operating systems.
Common features include –
Graphical User Interfaces
Ability to manage files and folders
Installing and running programs
Managing driver devices

11. What is an operating system?
Computer Hardware
Computer Software
Complete part 2 of the worksheet - Can you add the different hardware and software the operating connects together.

12. What is an operating system?
Computer Hardware
Computer Software

13. Operating Systems The operating system is part of the system software
All computers have an operating system, they cannot function without one
The operating system is a program that allows application software to communicate with the hardware
Examples of Operating Systems are Windows 7, Windows 8, Unix, Linux and Mac OS

15. What does an Operating System do?
Sorting out where to store data on disk drives
Dealing with security – user names and passwords
Organising files and folders
Managing data transfer from the CPU to the peripherals e.g. printer, monitor
Deals with saving, deleting, opening, closing files

16. Parts of an operating system
The kernel is the essential centre of a computer operating system, the core that provides basic services for all other parts of the operating system
The set of dials, knobs, operating system commands, graphical display formats, and other devices provided by a computer or a program to allow the user to communicate and use the computer or program
A device driver is a program that controls a particular type of device that is attached to your computer
A set of small programs that provides an addition to the capabilities provided by the operating system e.g. “print” utility

17. Single User, Multi-Tasking
Personal computers have a single user, multi-tasking operating system
These are designed for one person to use, but running many applications at the same time
Windows 7 and Mac OS X Mountain Lion are examples of this type of Operating System (OS)

18. Features of Operating Systems
Scheduling
How active processes are making efficient use of the CPU processing cycles
Memory Management
Making sure the applications are able to run and don’t interfere with each other
Allocation of Resources
Allocating things sure every user area has all the resources it needs
Tracking Usage
Producing bills for things like internet usage and printing
Data and user security
Authenticating users and keeping data and files private
System Services
Managing things like printing known as ‘print spooling’
Managing input/output
Managing data files – allowing the user to move, delete and copy files
Networking
Managing data packets connected to a network/internet

19. What is the purpose of an Operating System?

20. Without an Operating System, the computer can’t function!

21. Windows
It is a software operating system and graphical user interface that was developed by Microsoft.
Following its introduction in 1985, it became immensely popular among the personal computer users.
Its development had begun on two parallel routes.
The development on one route was intended for personal use while the other was for professional use.
The versions aimed at personal use featured greater multimedia support and lacked networking capabilities.
The professional versions of Windows offered greater networking and security features but lacked multimedia support.
Windows 7 was a huge success, and the relatively recent Windows 8 is also popular

22. Mac OS
Also known as Mac, Macintosh refers to a brand name that covers a series of personal computers developed by Apple Inc.
Apple produces Mac hardware and has its own operating system that comes packaged with all the Macs.
The Mac Operating System can be divided into two families of operating systems.
One is the 'Classic' Mac OS, which was shipped with Macs until the creation of Mac OS 9.
The second family is Mac OS X, which derives its features from Mac OS 9. The operating system that is currently in use is known as Mac OS X, successor of Mac OS, which is a line of graphical user interface-based operating systems.

23. Windows 7
Microsoft® Windows 7® is an operating system for personal and business computers, including both desktops and laptops
Programs that were designed to run on Vista will run on Windows 7, so performing a Windows 7 upgrading was a painless process, preserving programs and preferences.

24. Mac OS X Mountain Lion
Built on a rock-solid UNIX foundation, OS X is engineered to take full advantage of the technologies in every new Mac.
It delivers the most intuitive and integrated computer experience.
And it has iCloud built in, so you can access the content you use every day across all your devices.
OS X works with the processor in your Mac to deliver the best possible performance.
The desktop is clean and simple. It takes one click to open an app and a few more to buy, download, and install new apps from the Mac App Store

25. DOS (Disk Operating System) UNIX
DOS vs. Unix
DOS (Disk Operating System)
the first widely-installed operating system for personal computers.
for IBM by Bill Gates and his new Microsoft Corporation
non-graphical line-oriented command (menu-driven operating system)
UNIX
originated at Bell Labs in 1969 as an interactive time-sharing system
the first operating system written in the C language.
it is written in a standard language
first open or standard operating system that could be improved or enhanced by anyone

26. Comparing Windows Mac OSX Uses DOS Uses Unix Universally Used
Vulnerable to hacking
Limited features
Focus: office function
