2OPERATING SYSTEM AND PROGRAMMING
Section 1: Operating System
Client System:
The client system is the group of client or can be an individual system also. By the meaning of group
it mainly indicates an organization, community or a business. The client system mainly used for
communicating with a server. To elaborate the client system further in this case the Microsoft Windows
operating system will be used because the Microsoft Windows has all the features which is required to be
proper client system. The features are discussed below:
 A client system may need to serve many users. To serve many users in a single system different
accounts are needed and Microsoft Windows supports this multi-user feature [1].
 Communicating with the server properly is the main task of any client system. Windows operating
system does this job petty well.
 To meet all the requirement of the server the client OS need to handle all the resources within the
system properly. Windows OS is capable of this feature.
 Microsoft Windows can exchange the messages and resources with the server system. This is a
basic feature of every client base OS system.
 The Windows OS is capable to process the data without the help of server system.
Server System:
The server system works on the client-server architecture. The main aim of the server system is to
communicate with the client and handling the requests of the clients [2]. This type of system is designed to
communicate with the server. To describe the server system properly the Linux system is selected in this
case. The main features of the Linux system as a server are:
 The Linux OS is capable to access the both command level interface and the graphical user level
inter face [3].
 The Linux system is able to handle multiple clients at same time and can reply them with the proper
messages and resources.
 The Linux can provide the centralized system which is a must have feature of the server system.
This system is used for managing client system, administrative processes and for the security
services [10].
 The Linux can run on the solely on the commands. This can be useful for most of the cases for a
server system.
 The security level of the Linux system is high and the internal configuration of the network,
hardware and software is also secure for a proper communication method.

Mobile OS System:
The mobile OS system is user friendly for most of the cases and designed to run on the low
configuration. Most popular mobile OS is the Android operating system. The main features of the android
is:
 As the Android OS is specially designed for the general use purpose the security level of the
Android OS is much higher to protect the privacy of the users.
 The android OS is stable in the sense because the owner of it, Google LLC is always working on it to
introduce new features and for fixing the bugs.
 The Android OS is able to hide the inner implementation as it uses java for some core functions.
The java has the abstract class which can help to hide implementations [4].
 The Android OS is portable in the sense that beside in the mobile the X86 version of the android is
able to run on the desktop systems.
 The Android OS can manage the memory of the system itself because it is optimised for doing that.

I.i Remote Host:
To check the availability of a remote host the ping or telnet command can be used [5].
