Hello. Just about but the final checking, formatting and then the plagiarism checker. This is an advance draft before the time elapses then i send the final copy with the references and all. Thanks
Running head: OPERATING SYSTEMS
Network operating systems
The role of network operating system (OS) is to facilitate sharing of printers, databases,
applications, as well as file systems. It further enables the management of the name directory of
directories, offers security, and also does related network housekeeping functions. Normally, a
network operating system running a computer function as a server by offering a capability as that
needed for operating a network system. Such an OS may be suited for a client’s computer system
functionalities in a way that there is little difference between an OS network and an OS on its
own. Typically, the functions that are offered by a network’s OS range from sharing of files and
printing, data backups, administering user’s accounts and also security. For this to be possible,
the OS must have some installed components including server and client functionalities.
However, there are different functionalities that are performed by different network OSs
depending on their specifications which enhances their capabilities in tasks performance. For
example, the Windows NT server and workstation has multiple processors which are run on
RISC and Intel devices and are capable of performing preemptive multitasking. On the other
hand, the Windows 95 is not capable of using such multiple processors or operates on RISC
computers or use NT drivers, although it is capable of using older drivers.
Therefore, the OS/2 can function in preemptive multitasking operations, multithreading
as well as protecting applications from each other. It is supported by RISC and Intel computers
with 1 processor with a minimum of 386 and 8M of RAM. However, there are DOS drivers that
does not work with OS/2 or operate on DEC Alpha systems. The Mackintosh OS however has
cooperative capabilities as well as preemptive multitasking using windows, icons, and mouse
Design shift between platforms from Peer-to-Peer to Client/Server and now Virtualization.
The two terms used to describe the platforms “client/server” and “peer-to-peer” may
sound foreign although they describe how each network is structured and their suitability for
particular tasks. However, the models differ in many ways n their operations. The peer-to-peer
(P2P) network does not have a central server as every workstation on its network share files
equally. It does not have a central storage or require users’ authentication either. However, the
client/server platform has distinct servers and clients and users may share most files, normally
stored on its server which decides will the files a user can access on its network.
Owing to the fact that technology is very dynamic, there has been a growing shift in
platforms from the previous peer-to-peer to the client/server and now to the more versatile
virtualization. The Client/server platform involves a program, referred to as the client, making a
service requests to another program, the server. Despite the fact that this model is usable by
programs within one devi...
