List down all the operating system used in a desktop/laptop today
and find good descriptions of how operating systems work? Hence, state their
advantages and disadvantages.
How operating systems work?
The operating system acts as an interface between an application
and the hardware. The user interacts with the hardware from "the other
side". The operating system is a set of services which simplifies
development of applications. Executing a program involves the creation of a
process by the operating system. The kernel creates a process by assigning
memory and other resources, establishing a priority for the process (in
multi-tasking systems), loading program code into memory, and executing the
program. The program then interacts with the user and/or other devices
performing its intended function.

Advantages

1.
The first main disadvantage of the windows 7 is the hardware configuration.
Windows 7 needs RAM capacity of at least 1 GB.
2.Windows
7 cannot be easily upgraded from windows XP. It has the drawbacks in
upgrading the operating system in the easy manner.
3.
Only the advanced users are convenient with the windows 7. New users find it
difficult to use windows 7 and they switch back to windows XP itself.
3.
Sometimes driver support is not providing for the old systems and the old
version of motherboard. This disables some of the features in the windows 7.

has a lot of new and very nice features that aren't in other versions.
4.
Sticky notes and the gadgets of the windows 7
5.Windows
update feature for all the software and components.
|
1.
Take some time to learn.
2.
Fewer
computer programs, games and utilities are available for Linux
3.There
are still some manufacturers that do not offer hardware support for Linux OS,
although there are fewer every year.
3.
Some
of the latest and greatest hardware that is being produced is not compatible
with Linux
|
Linux
 |
1.
Most
software can be obtained without cost for Linux.
2.
Linux
has the advantage of the code being in the public domain. This can be a
double-edged sword; while you can look at the code, and developers can fix
holes rapidly, it also means hackers can find bad code.
3.
If
you have used other operating systems, once you have made the switch to
Linux, you will notice that Linux has an edge over Windows
|
1.
Mac
OS is difficult to theme (in Tiger, you can purchase Shape Shifter, in
Leopard, you may use Magnifique
2.
Mac
OS is also more limited in preferences than Windows, but there are plenty of
3rd party applications to tweak the operating system, and there is the
Terminal application that can also tweak other system settings.
3.
MAC
OS are more expensive generally than others.
4.Fewer
computer programs and games are available for MAC

1.
High quality hardware: Macs may be expensive, but they're worth it. Macs are
very tough and take a lot of abuse, also they last a long time if you treat
them well. My mac is a Titanium PowerBook G4, and 7 years old. It's still
working great! (except for the old outdated Mac OS [10.2.8] and lack of
enough RAM)
2.
Ease of use: Mac OS has always been a highly user friendly operating system.
3.
Mac
OS has been around longer than Windows, and has had a lot of improvements
made to it
4.
MAC
is a much more secure OS, and rarely being attacked by viruses and malware
