“It is the clearest ever picture of hydrogen emitted from the Small Magellanic Cloud,” said Dr. The new image of the Small Magellanic Cloud was captured as part of the Galactic Australian Square Kilometre Array Pathfinder (GASKAP) pilot survey. It has a complex structure due to gravitational interaction with the Milky Way and the Large Magellanic Cloud. The Small Magellanic Cloud is located about 210,000 light-years away in the southern constellation of Tucana. Image credit: Pingel et al., arXiv: 2111.05339. In addition, since Vista is a relatively new Operating System we can expect better performance in its later versions.This image shows the Small Magellanic Cloud, a dwarf galaxy that is a satellite of our Milky Way Galaxy. Thus, it is definitely necessary for our company to replace XP upgrading it to Vista, as it is undoubtedly better in its performance, has numerous rich features and manages computer resources better than XP. demand fetching enabling applications to load 3 times faster, Network Center, which has replaced My Network Places, Windows Future Storage, which is a new generation data storage engine, and Metro, which is a new document formatting tool, are among the best features of Vista that is unavailable in XP. Cool Graphics, Image-based Setup, UAP, Shadow Copy Recovery Service without Server, Windows Defender, Super Fetch, i.e. Vista has a Pervasive-Device Synchronization feature that allows us to synchronize data over multiple servers, PCs, PDAs and cell phones. We can also organize the information in virtual folders. It also has a System-level Instant Desktop Search feature which allows us to find documents and files, photos and even e-mails in a snap and is a lot quicker than the available Search option in XP. We can organize and edit photos for company presentation using the Windows Photo which is absent in XP. There are many more facilities in Vista, which we can enjoy. Although, its main intention is for the parents to keep an eye on the children it can also be used in the office to keep an eye on the employees, denying them access to certain sites. Unlike XP, Vista has a sidebar feature, which allows quicker access to programs saving our valuable time.Īnother remarkable feature in Vista, which is not present in XP, is Parental Control. Vista will not install in drives formatted with FAT32 file system and the NT Boot Loader in XP has been replace by the Windows Boot Manager. With Secure Startup, integrity of information is intact even if our machine is lost or stolen. The former can be downloaded but it is not accompanied with the application and the latter is not available in XP. Vista has Windows Defender, which scans and removes spyware and the BitLocker Drive Encryption that helps to protect data in stolen devices. (Koch, 2002) Administration and management It has a File and Registry Virtualization feature, which enables it to avoid LUA bugs in the third party applications. Even the administrator has to confirm his intentions giving security credentials before executing tasks. Thus, unauthorized users cannot make any inadvertent changes to the system settings, install malicious actions and perform various other acts. In Vista, the User Account Control limits the nature and utility of the application software to general user privileges until the administrator increases the level of privilege. There are many areas where Vista outperforms XP, like in file copying operations, which is faster. This will reduce the risk of virus attacks, worms and DoS. Nevertheless, Microsoft rebuilt the TCP/IP stack in Vista itself, thus, being able to include domain and server isolation techniques, which use IPSec for restricting access to the network. Another important feature is the use of IPSec which is a protocol used to secure data packets and authenticate them. This is because Vista operates on a well-defined and effective secure networking technology, like domain and server isolation, and has improved its networking stack. We need to upgrade our operating system from XP to Vista as its security enhancements will be a boost for the company. Although XP is at present the leading Operating System in the market, it suffers from security issues and has performance problems. The most important thing for a company is securing its data and information from getting into the wrong hands. These elements or components that make Vista a better option are user and shell interface, administration and management, security architecture, and networking technologies. These aspects are important for any user and the Vista provides a better and more advanced level of these components. Vista and XP are considerably different from each other with respect to different aspects. The new Windows Vista is highly recommended and it is mainly useful for a medium-sized information-service company and it rates higher than the current Windows XP for a number of reasons.
