A level Computing:
Comparing operating
system's features
- Desktop
- Must be able to run many
different types of software
- Usually requires large amount
of processing power
- Must support a wide
range of peripherals
- Must run on a wide
range of hardware
- Must be able to run many
different types of software
- Embedded
- lower hardware requirements
- limited or no user interface
- designed to operate on its own
from within other machinery
- limited memory capacity
- limited battery life in
potable devices
- lower hardware requirements
- Network
- redirects requests for resources
elsewhere on the network
- layer of software added to
the operating system
- redirects requests for resources
elsewhere on the network
- Mobile
- limited amount of memory
- limited amount of
processing power
- battery of limited power
- must manage a
network connection
- some embedded features
- continually sending data
packets to the mobile
phone base stations
- continually sending data
packets to the mobile
phone base stations
- limited amount of memory
- Interactive
- User interacts directly
with the system
- user receives the results of
processing immediately
- User interacts directly
with the system
- Server
- optimised to provide a
specialised service
- maximises performance
on that task
- optimised to provide a
specialised service
- Real-time
- inputs are processed in
a timely manner
- output can affect the
source of the inputs
- support programs which
are non-sequential
- deal with unpredictable events
which can happen in parallel
- carry out processing and produce
response within specified time interval
- must be fail-safe
- Examples
- Aircraft control system
- Camera
- Aircraft control system
- inputs are processed in
a timely manner
