1.1 Types of operating systems
Being known to be one of the important software in a computer, an operating system is
set to the tasks of managing the memory and processes of a computer including both the
hardware and software part of a computer. You can with the help of an operating system
communicate with a computer without talking to it. A computer, therefore, can be declared to be
useless without an operating system (Technopedia, 2018). Since the error of first computer
generation, an operating system has been there despite all the evolving processes that are known.
There are a number of types of operating systems which I am going to share in this chapter.
1.1.1 Batch Operating System
In this type, there is no direct interaction between the users of the operating system with
the computer (Pillai, 2017). Users have to involve the services of off-line devices a good
example being punch cards to be able to prepare their jobs and there after they submit them to
the computer operator. There is a need for batching jobs with similar characters together and
running them as a group so as to speed up the processing rates (Anderson, 2018). It is usually
the work of the operator to make sure that the jobs that are left with him by the programmers are
sort into batches with respect to similar requirements. There are some disadvantages that came
with Batch Systems like the absence of user job interaction, slower speed due to delayed
mechanical input-output processes, and poor prioritization.
1.1.2 Time-Sharing Operating Systems
Here, users located at different locations are able to use a particular computer just at the
same time. This is also referred to by many as multitasking or a logical continuation of
multiprogramming. The time of the processor that is shared by many users at the same time is

Network Operating System 4
what is simply termed as time-sharing (Chasing, 2018). When differentiating between Time-
Sharing and Batch Systems, in Time-Sharing, the main objective here is to reduce response time
whereas, in Batch Systems, the main objective is to reduce processor time. Time-Sharing
Operating Systems have the advantages like Quick response time, reduced CPU idle time, and
there is no duplication of software. However, it is disadvantaged in terms of reliability, poor data
communication, and the user’s data is not very secure in this type of Operating System
(Networks, 2015).
1.1.3 Distributed Operating Systems
Multiple users and multiple real-time applications are served by multiple central
processors in these types of operating systems. There is the distribution of jobs among the
processors accordingly (chennaicisco. 2013). Various communication lines are used by the
processors like the likes of high-speed buses to communicate to each other. Distributed systems
are also referred to by many people as loosely coupled systems. This types of Operating
Systems have the advantages like a high rate of data exchange through electronic mail, sharing of
resources among users, the robustness of the system since the failure of one site does not affect
the other, minimal delay in processing data, and the host computer is relieved a lot of burdens
(Mullins, 2018).
1.1.4 Network Operating System
This type is set to run on the server allowing the serve r to manage users, data, security,
applications and many more tasks (Cisco, 2013). This type mainly came to enable sharing of
resources among users over the network. There are examples of network operating systems like
Linux, Unix, Mac OS, Microsoft Windows Server 2003 among others. This type has the
advantages of good server managed security protocol, the stability of centralized servers, easy
upgrade process, and the advantage of remote access (ComputerNetworkingNotes. 2018).

Network Operating System 5
Despite all these advantages, these types of Operating Systems have downfalls like high cost,
decentralization, and maintaining and updating is required regularly.
1.1.5 Real-Time Operating Systems
In these types of systems, the time interval for data to be processed and the response to
input is very minimal to an extend that it ends up controlling the environment. The response time
is that period hat is required from the input moment and the output time. Therefore, this is to
mean that in this method, there is less response time when compared to the online type. These
types are used in case of rigid time required in consideration to the flow of data (Docs.ovh.com,
2018). There is a need for a real-time operating system to have the characters of fixed time
constraints to avoid failure. There are as now two types of real-time operating systems namely
Hard and Soft real-time systems. In hard real-time systems, there is a guarantee of on-time
completion of critical tasks and there is no secondary storage meaning the data is just stored in
ROM hence you can conclude that there is no virtual memory. In case of Soft real-time systems,
there are minimal restrictions. Tasks are executed in terms of priority meaning that high priority
tasks are executed until they are over so that the next in line task can come in (Mitchell, 2017).

Network Capabilities for Windows Server 2016
The network capabilities for Windows are complex compared to Linux. There are only
two ways of setting up a network in Windows unlike in Linux where it can be done manually
(Lowe, 2016). There is an option of using a Network Setup Wizard for new users and there is
also a manual way used by experts which in this case is more tedious.
