1. What is computer software?
Anything that can be stored electronically is software.The storage devices and display devices are hardware.
The terms software and hardware are used as both nouns and adjectives.For example,you can say:”The problem lies in the software,”meaning that there is a problem with the program or data, not with the computer itself.You can also say:”It’s a software problem.”
The distinction between software and hardware is something confusing because they are so integrally linked.Clearly,when you purchase a program,you are buying software.But to buy the software,you need to buy the disk (hardware) on which the software is recorded.
Software is often divided into two categories.
Systems software :Includes the operating system and all utility programs that manage computer resources.
Application software :Includes programs that do real work for users.For example,word processors,spreadsheets and database management systems all under the category of application software.
2. Windows Vista
As early as 2001,rumors regarding Microsoft’s next generating operating system,at that time known by its code name Longhorn,were being spread around the Internet.In July of 2005,Microsoft officially named Longhorn Microsoft Windows Vista.The tagline for the product was “clear,confident,connected.”Although the product was originally expected to debut some time in 2004,Windows Vista has been strategically postponed by Microsoft on a number of occasions.Now at last Microsoft has officially released Microsoft Windows Vista.In addition,other products from the Microsoft world have also been released including Microsoft Office 2007 and their latest release of the Microsoft Exchange Server.
Windows Vista has taken Microsoft 5 years to develop.In the course of development ,several features have been either cut or added.A major issue that Microsoft is focusing on in their new operating system is security.Windows XP was full of security issues,and thus had new updates coming out very often in order to patch these security holes.In addition to security ,Microsoft has also completely revamped the user interface of Windows Vista.
Some of the Windows Vista’s features include the following:
Detects hardware problems before they occur,which is designed to reduce the frequency of incidents in which applications stop responding or the PC needs to be restarted.
Windows Vista security features protect against the latest generation of threats,such as worms,viruses and spyware .If an attacker manages to compromise a computer ,Windows Vista limits the damage.
Faster start-up time and low power consumption of the new sleep state.In many cases,Windows Vista is noticeably more responsive than Windows XP on identical hardware.
Windows Vista simplifies and centralizes desktop configuration management,reducing the cost of keeping systems updated
