Section 1: Operating Systems(OS)
Comparison and contrast the Unix OS with Window OS in terms of :
Stability
Unix OS is more stable compared to windows OS. Unix OS is the most scalable and reliable
OS because it usually is tightly integrated with the hardware. The massive UNIX vendors
have the advantage of coming up with their various OS versions around their hardware
that permits them to possess hardware with less incompatibilities and problems than
Windows OS. [1]
Performance
Unix OS run faster in desktop than Windows OS. This feature of Linux makes it more
suitable software development environment. Developer find it easier to use Linux than
windows since most of development tools are provided by default. [2] Also Unix OS are
known to have better hosting environment compared to windows OS.
Compatibility
Almost all application tends to be designed to run in windows OS. Although there are
alternatives Unix applications in the market for windows, some don’t have alternatives.
This makes it important to ask yourself if there exist an alternative to the application you
are using in windows before you migrate to Unix OS.
If there doesn’t exist an alternative for Unix, one can use some software such as WINE or
VM to run windows applications in Unix OS. [3]
Installing applications in Unix is usually done by typing the correct commands in the
terminal. One can install the application from the repository while other need to be
downloaded and installed directly the source. Windows OS users aren’t affected by these
incompatible issues since installing applications in windows is much simply compared to
Unix. [3]
Reliability
Unix OS is additional reliable in comparison to Windows. Unix OS has a reliable in build
security measures. Developers of Unix versions are much active and unleash major and

minor updates time to time. Historically systems that run in Unix OS are well-known for
running for many years without failures or need to restart. UNIX operating system OS is
additional reliable in terms of security than window OS. Hackers or virus developers realize
it harder to penetrate through Linux as compared to window OS that is more prone to
viruses and malware without ant-virus program. Once a programme hang in windows,
typically it’s troublesome to kill the programme even through task manager. In Linux, any
application can be terminated with the XKill command. [4]
Short Answer Questions
a. Open source code OS is a software system whose source code is freely out there for users.
Open source OS is taken into account safer compared with closed source OS. OS like UNIX
is an open source OS. Since everybody has access to the codes, bugs and week points of OS
are found faster and so they are fixed faster, closing up security holes quicker. In addition,
anyone and everybody are free to produce a higher, safer version of the package. [4]
b. In multiprogramming and Time sharing there are problems such as:
i. There is stealing of personal files or other data.
ii. Resources e.g. main memory and other hardware devices are used without
proper management.
c. It is impossible to make sure the identical degree of security in time-shared machine as
we've got in dedicated machine since any security scheme designed by humans can be
broken by a human, and therefore the more complicated the scheme, the harder it's to feel
assured of its correct implementation.
d. Kernel is a software that provides save multiplexing to underlying hardware. Kernel has to
provide at least the following three functionality;
i. Scheduling.
ii. Protection.
iii. Message passing.
e. They reside in libraries and applications (user space). User space interacts through system
calls with kernel. System call is an entry point to kernel [4][.
