Operating System Essay

That means that with the network operating system we can have lots of users all concurrently using resources on our serve.One of the most important aspects about server operating systems is the security. Workstation OS provides great security for end-users, but it's still not as tight as the security offered by the network operating systems. The reason for that is that with the network operating system were providing services to hundred or thousands of concurrent users. Therefore security is critical Workstation operating systems also provide some type of authentication by using user names and passwords which reside on local database on the local

Q. What is an operating system? A. Operating system works as an interpreter between computer Hardware and application. Operation system works as a user interface. Q. Types of Operating systems? A. There are two types of operating systems 1. SOS: Simple Operating System as for example- Windows 95,98, ME 2. NOS: Network Operating System as for example- Windows NT, 2000, 2003. Q. What is server?

The hospital’s administrative network consists of Apple iMACS and thin computers that use 1000Base T with CAT 6 cables. All work stations belonging to Executive Management has Apple iMAC computers with 24” monitors, 2.4 GHz speed, 2 GB RAM, and a 500 MB hard drive. Human Resources, OPNS, and the Finance Senior Managers have Apple iMACS with 20” monitors, 2 GHz speed, and a 350 MB hard drive. All of the systems have OS virtualization and use the MAC Operating System X, Leopard, and Windows XP. OS virtualization allows separate, isolated virtual environments to be used on a single server. The MAC Operating System X is a UNIX system that is both simple and powerful. Leopard further enhanced the system by making it faster and more reliable. Windows XP is a product of Microsoft but it is able to be installed on any MAC using a native version of Microsoft Office. This way users are able to create documents using MS Word, make presentations using PowerPoint, and

at a time,they are commonly connected to a LAN and run multiuser operating system.The resources which has to be managed

A computer and a server are usually two unique and separate devices and each are customized to handle specific functions and purposes. For example a web server will not need any type of display or monitor and can be located anywhere. But when it comes to a data server or client, there is typically a need for some form of display monitor so information can be reviewed and tracked. It is not uncommon in some occurrences that a device can function both as a computer and a server for the same application. This also can hold true for a application act as a client to other server for various other

Client Server is a computer system where a central server provides data of networked workstations.

An operating system is the software that supports a computer’s basic functions, such as planning tasks, performing applications, and controlling peripherals. When choosing and introducing the best system for a business such as this, it’s important to make sure it fits the needs of the business while being easy to install, set up, manage, and understand. For this reason, I decided that the Apple OS X Server would be a good choice for this business. The OS X Server allows for more power, governing, and alliance throughout an organization. It has many features that would be a valuable addition to running a company. For example, file sharing makes it easier than ever to share and exchange documents between personnel and helps protect against tampering and spying by encrypting data. The Profile Manager feature easily creates profiles to set up user accounts for mail, contacts, calendars, and messages. It also enforces constraints and password guidelines. Another feature, the Caching Server, speeds up the download and delivery of software quickly and safely. With these features, and many others, setting up and

In the workplace today there are many different options for operating systems be they providers of server related services or end-user desktops there is a different Linux distribution for many different applications. There are also a number of advantages and disadvantages to adding onto or switching network operating systems within a company. In the following pages I

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

Both Windows and Linux come in many different forms. All the different forms of Windows come from Microsoft, the various distributions of Linux come from different companies (ex. Red Hat, SuSE, Linspire, Ubuntu, Mandriva, Knoppix, etc). Windows has two main lines: “Win9x”, which is consists of Windows 95, 98, 98SecondEdition and ME, and “NT class” which consists of Windows NT, 200 and XP. On a side note, Windows first had version 3.x which was made before Windows 95 by a couple of years. The various types of Linux are called distributions. All the Linux distributions released around the same time frame will use the same kernel, which are the guts of the OS. They will differ with the add-on software provided,

This paper will discuss three main operating systems, Windows, Linux, and OS X. All three of these operating systems have features which are unique unto themselves. Although there may be arguments as to which one of these three operating systems is better it really all comes down to what features are needed for each user. This paper will describe the features that each of these operating systems has to offer.

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.

The Linux was originally founded by Linus Torvalds. In 1991, he was a second year computer science student in Finland. He sought after an operating system that was similar to the UNIX system, but both UNIX and the hardware it ran on were excessively expensive. A UNIX version called Minix was available for free, but it did not reasonably meet his needs as it was simply an operating system for students, designed primarily as a teaching tool rather than an industry strength operating system. As a result, Torvalds studied Minix and proceeded to set out to write a new version. After six months of working to produce the new operating system, Torvalds made very little progress toward the utility of the system.

In Windows, you can run lots of different program programs. There are customized programs and off-the-shelf (common) programs. These allow you to do everything from running your bowling league to typing up a correspondence.
