Software
- Refers to the programs we run on our computer - the programs
are the stored sets of instructions given to the processor to carry
out. It also refers to the data that is used by the proograms
- Types
- Utility Software
- Has limited functionality and is
used to maintain computer systems

- Functions
- Memory
Management
- The OS manages the transfer
of data between the CPU,
RAM and main storage
- The OS manages the transfer

- User Interface
- The OS provides the user with a way of
controlling the functions of the computer
without resorting to machine code
- Command line interface (CLI) e.g. MSDOS.
Commands can be grouped into shell
scripts to carry out maintenance jobs
- Graphical (GUI) e.g.
Windows. Uses icons
to represent actions.
No commands have
to be learned.
- Command line interface (CLI) e.g. MSDOS.
Commands can be grouped into shell
scripts to carry out maintenance jobs
- Acts as a boundary between human and machine
- The interface lets users give commands,
ask questions and display a response
- The OS provides the user with a way of
controlling the functions of the computer
without resorting to machine code
- Peripheral Management
- The OS manages the input and output
devices connected to the computer,
like a keyboard, mouse and printer
- The OS manages the input and output
devices connected to the computer,
like a keyboard, mouse and printer
- Multi-tasking
- The OS allows more than one
program to be run at once so users
can switch between applications easily

- Security
- The OS provides security
features to restrict access to
the system or particular files

- Memory
Management
- Functions
- Controls hardware and acts
an an intermediary between
application and hardware
(hides complexities and allows
user to operate computer
without writing programs
- Operating System
- Utility Software

- Security
- Anti-virus
- Detects and protects the computer against
virus threats and quarantines infected files

computer from the applications that are running
- Spyware protection
- Detects and removes spyware
(small programs that quietly
monitor what you are doing)

- Disk Operations
- Formatting
- Sets up a hard drive, memory stick or
card into a format that the computer can
use to store/retrieve data. the process of
formatting erases any data that was
previously on the storage medium

- File transfer
- Allows movement of
files from one location
to another, either locally
or via memory stick
- Allows movement of
files from one location

- Defragmentation
- Re-organises the data on the hard
drive to improve read/write access time

- System Maintenance
- System info and diagnosis
- Provides information about the system in
order to help with diagnosis of problem

- System cleanup tools
- Removes temporary files and
compresses/archives unused
files to increase free storage

- Automatic updating
- Uses the Internet to check the OS
is up-to-date and applies software
patches/fixes as necessary

- Translators
- Compiler
- Translates all code at once,
fast but prone to error

- Compiler
- Library programs
- Collections compiled routines which are shared by multiple programs
- Printing fucntion
- Interfaces (i.e. all Microsoft
software has a similar interface)
- Graphic engines of computer games
- Printing fucntion
- Collections compiled routines which are shared by multiple programs
- Virtual machine
- Links hardware applications
and the user but hides the
true complexity of the
computer from the user and
other software
