Essay on Explain the Purpose of an Operating System

This paper will elaborate on the major differences of the main Operating Systems (OS), which are UNIX/Linux, Mac®, Microsoft® Windows®. The areas of discussion for this paper will be on Memory Management, Process Management, File Management, and Security for each operating system. Operating Systems (OS) for a computer is the main processing software program used to allow the computer processor to communicate with the software and hardware I/O devices. Computers as SUN, SUSE use UNIX/Linux operating system, Mac® (Macintosh) computer uses Apple operating system, and Personal Computers (PC)

1)A network is when two or more computers are connected together and are able to share data and communication.

Workstation: A workstation is an area accessed by a user. There are many different types of workstations, but the network workstation makes sure that they are connected to an office LAN so they can access other workstations if needed. It can be used for any job, such as gaming designer, video editing, architect ect. The network workstation allows people to share their files to any other workstation as long as they are connected on the LAN.

It is very easy to communicate through a network. People can communicate efficiently using a network with a group of people. They can enjoy the benefit of emails, instant texting, telephony, video conferencing, chat rooms.

"A network is an interconnection in between two or more systems or computers in an order to communicate each other by sharing the data ". Today, networking concept got importance by its features, especially of sharing the information and is widely practicing in an Organization level too. Mainly networking concept is categorized into 3 main categories based upon the performance namely LAN, MAN and WAN.

What is Operating System Security, Operating system security is the process of ensuring OS integrity, confidentiality and availability also OS security refers to specified steps used to protect the OS from threats, viruses, worms, malware or remote hacker. OS security include all avoiding-control techniques, which safeguard any computer information from being stolen, edited or deleted if OS security is included. OS security allows different applications and programs to perform required tasks and stop unauthorized interference. OS security may be applied in many ways. We 're going to discuss following topics in this article. A brief description about security and what are the types of encryption and what is Authentication, One Time passwords, Program Threats, System Threats and Computer Security Classifications.

A network is the way to communicating throughout the internet; also, it is connected to the group of computers that allow to sharing the information through a network. Not only that network is just for sharing the information though connected of group computers, but for internet that including social media, game online, telecommunication, programming that would be require network for professional career, and more that can be any in the real world, even that can be also for security throughout network to protect whoever uses network for personal and business. A network is a-must

10. You are using the grep command, but it is only searching through files in your immediate home directory. What option enables you to search through subdirectories below your home directory?

A network enables all PCs and devices to exchange data with each other which means they can all communicate with each other with information and data.

The working framework is the most noteworthy basic of all the framework programs, it controls all the PC's assets and gives the base whereupon the application projects can be composed (Tanenbaum, 1992). Consequently, it is essential for PC clients to choose a powerful, tried and true, stable working framework, which can execute programs in an advantageous and productive way. Linux working framework, which is generally utilized as a part of late years, has turned out to be progressively well known in the PC world. The improvement in Linux working framework started in 1991, when a Finish understudy, Linus Torvalds, composed and dedicated Linux, a little yet independent part for the 80386 processor, the main

Explain the key components required for client workstations to connect to a network and access network resources.

Linux is a trademark owned by Linus Torvalds [1]. It is an operating system which is powerful, free and inexpensive to own based on UNIX [1]. It is a POSIX-compliant with versions available to install in cell phones, supercomputers and most computing systems [1]. Linux is an open source program as its source code is available to the general public for use and the right to modify from its original design without any charges [1]. New code will be added to the next version made available with Linux if it is accepted as a universal improvement [1]. The code will continue to exist and developed by the user even if the company fails [1]. Moreover, updates for Linux are available every six months [1]. Nowadays, Linux is in constant development by

When looking into the selection of an efficient and effective, secure operating system, each aspect must be taken into consideration. Many of the international companies have developed numerous actions for handling the operations in a beneficial way. The secure operating system offers enhanced security for the information stored at each company. It also is very helpful to protect the information of the customers. The key objective is to establish a Software Network Bridge that encourages the implementation of the Linux operating system in a useful way. It is well known that being able to implement a Linux operating system there must be a lot of focus on many different features..

With computer networking, you can use a lot of software and hardware available on the market which can just be stored or installed on a server and can be used by various workstations.

Computer network also allows the user to share resources such as printers and faxes. It can be installed on one computer and can be accessed by other users in a network. By this the need of installing printers on individual computers is avoided and it result in cost-effectiveness. Computer network also allows the user to communicate with each other using
