Comparison between Windows xp and Windows vista

Windows XP and Windows Vista were 2 succeeding versions of Microsoft’s Windows computer operating system. Microsoft marketed both versions as main updates of Windows with new features, improved security and better overall consistency. Each system came already loaded on personal computers from many different manufacturers and was also available as an advance for existing Windows computers.

History

Windows XP went on sale around the globe in October 2001. It replaced the existing Windows Me (Millennium Edition), which had appeared about one year before. Windows XP was the major operating system offering from Microsoft until Windows Vista went on sale in early on 2007. Windows XP’s life duration of more than five years makes it one of the longest releases of any version of Windows. In October 2009, Microsoft released Windows 7 to swap Windows Vista, giving Vista a more distinctive two-to-three year life cycle.

Appearance and Versions

Windows XP retains most of the visual cues and icons from previously editions like Windows Me and Windows 2000. Microsoft created three different versions of Windows XP, targeting various users: Windows XP Home Edition was design for casual users, Windows XP Professional for businesses and users with more highly developed systems, and Windows XP Media Center Edition came with unique features for playing DVD video, recording music and viewing television programs.

Windows Vista was a visual exodus from its predecessor, giving Windows an extra streamlined appearance (known as the Windows AERO scheme) and replacing the common “Start” rectangular icon in a circle Windows logo in the bottom left-hand corner of the home screen.

Security

Though Windows XP came standard with basic security features, Internet safety was a main concern and criticism of the operating system. In particular this was because of the number of viruses to which Windows XP was susceptible, along with the huge amount of control given through an Administrator account kind (which could make the entire system vulnerable if accessed without authorization). Microsoft highlighted improved security with Windows Vista, including a User Account Control feature which removes administrative privileges that hackers might be able to use.

Features

Moreover enhanced security, Windows Vista includes some other notable features lacking in Windows XP. One of the features is Windows Sidebar, which gives Windows right to use small applications known as Desktop Gadgets. One more feature exclusive to Vista is the Instant Search feature, which displays predictive results while the user is still typing a search word. Windows Vista also brought updates of popular programs as well as Internet Explorer, Windows Media Player and Windows Calendar.

Performance

Both Windows XP and Windows Vista consist of built-in support for both 32- and 64-bit applications. In terms of user opinions and standard testing, the operating systems reveal same performance capabilities. In a few tests, including 3D graphics tests, Windows XP in fact outperformed its newer counterpart. In real-world scenarios, users are much more likely to experience improved or worse performance due to hardware and application differences rather than which of the two Windows systems they run.

Comparison of security products for network

A computer network is a joined system of computers and peripherals that may permit them to work in concert, share resources, be controlled and customized centrally, as well as allowing them to be protected or limited as a group. Security software is, generally speaking, any software that helps preserve a system or network from risk or threat or to keep the data itself secure. Computer network security software, then, is software that aims to defend a network and its data in a range of ways and from a variety of threats.

One may frequently think of computer network security software as being separate products or suites of products devoted only to security. But, this kind of opinion would ignore a very important type of security software. The missing component would be the security patches issue by manufacturers of operating systems. They’re aimed and security and they’re software, so even although they are updates to software that is mean to run a computer, they still calculate.

The products that are more expected to come to mind as computer network security, software are those that start with “anti.” These consist of anti-virus software, anti-malware — malware is short for “malicious software,” and anti-spyware. The three names are used somewhat differently by various manufacturers, but generally, the software is designed to catch and disable or prevent the infringement of viruses, worms, Trojan horses, backdoors, root kits, spyware, and at times also bonnets, keystroke dialing attacks, spam, and phishing attacks.

Broadly talking, security includes data security, and thus computer network security software includes software with automatically backs up data. For yet greater security, backup can be done to an off-site location. Backup software can be set for the rate of backups and the location of the drive or server to which the backup is prepared. Data encryption can also add to data security.

In the area of defending the system from unwanted intruders, there are at least 4 roles that computer network security software can play. For 1 thing, one may consider a properly-configured web browser as security software, as the handling of cookies, passwords, downloads, attack sites, and web forgery contribute to the security of a system. Second, firewall software, on a computer, a router, a server, or all three, helps to stop intrusion. One can go still further with network scanning software, intrusion detection software, or a log-in system that only grants admission to the network to pre-approved individuals.

Network access to Internet technologies has proved to be helpful to organizations, including their employees, customers, suppliers, and business partners. This has not move toward about however without any increase in network security exposure and sharp competition for messaging resources. New capability such as intrusion detection, content screening, and URL blocking and bandwidth management has become obtainable. Service strategies give network security software products with firewalls and usage management software that allow companies to efficiently address these challenges.
