Operating System Analysis

Introduction

Operating systems consider being the most important element in the generation of modern computers. It is due to the operating system that supports the other programs known as software to run over it. Choosing the correct operating system is quite difficult for the user. The matters that should be consider while selecting an operating system includes internet connectivity, user friendly, supports most of the applications or can be dealt with ease in case of any failure. DOS, Windows, Linux, UNIX are few operating systems that are mostly available in now days (Ichbiah, 65-72).

Discussion

An operating system is basically a collection of programs that provide control of the Central Processing Unit. Here, we will discuss windows XP and its features. There are many operating systems that are used usually in general purpose computers which are discussed below:

Increased security for PC

Windows XP has features that prevent intruders from the Internet, protect your files confidential and restore the stability of the system in case of a failure. The safety had always been one of the weaknesses of Windows. It was enough to have access to a Windows based PC to steal files or change the user settings. Connections for broadband Internet, the possibility that a hacker from entering remotely to the PC was a risk latent. And a program or a faulty device driver flaws could cause difficult to correct for common users. With its roots in an operating system business, Windows XP is more secure. This version includes a firewall that prevents access basic intrusion on the Internet, offers several options to protect private files and has a tool to 'return' a faulty PC to a point which worked well (Cusumano, 147-152).

Memory Management

Process Control

Windows 98 and ME do not provide a system to protect the private files of each user, a large deficiency especially when several people share a PC. In Windows XP, in contrast, you can create accounts separate for each person who uses a PC. Thus, each user has a customized desktop, an own list of favorite sites and programs different from the Start menu, also can be isolated from personnel files. Windows XP creates game separate folders to store files and user settings (My Documents, Favorites, Start Menu, etc). And whenever you start the program is a welcome screen where each person chooses their own (you can place a photo or image to represent you).

By default, the accounts have no password, but this can easily be placed from the Control Panel. However, the password itself is not blocking access to personal files, it is necessary to check the Set as private item that appears when you create the password. Thus, all documents stored in the My Documents folder (and subfolders within it) are beyond the reach of other users of the PC. There is a condition so that files are protected: You must select NTFS as the file system on the PC (see box "NTFS, a file system stronger"). While the PC is kept with the ...
