7. What is ISA Server 2004 Microsoft Internet Security and Acceleration (ISA) Server 2004 is the advanced stateful packet and application-layer inspection firewall, virtual private network (VPN), and Web cache solution that enables enterprise customers to easily maximize existing information technology (IT) investments by improving network security and performance. ISA Server 2004 is available in two versions: standard edition and enterprise edition.

8. What is ISA Server 2004 ISA Server is particularly well suited for protecting large enterprise network configurations requiring multiple firewall arrays in disparate locations that are running Microsoft client and server applications, such as Microsoft Office, Office Outlook Web Access 2003, Office SharePoint Portal Server 2003, Internet Information Services (IIS), Routing and Remote Access, Active Directory directory service, and many other Microsoft applications, servers, and services.

9. What is ISA Server 2004 ISA Server contains a full featured, application-layer aware firewall that helps protect organizations of all sizes from attack by both external and internal threats. ISA Server performs deep inspection of Internet protocols such as Hypertext Transfer Protocol (HTTP), which enables it to detect many threats that traditional firewalls cannot detect. The firewall also provides VPN client inspection for Microsoft Windows Server 2003-based quarantine solutions, helping to protect networks from attacks that enter through a VPN connection.

29. What is Cache An area of disk space which stores the text and graphics of a viewed web page. When the web page is revisited, the Web browser will retrieve the data from the cache instead of downloading it again to save time.

30. Or, is an area on the hard disc of a computer where web pages and page elements (graphics etc) are stored when a page is downloaded from the Internet. If a page is revisited and the page, or elements of the page, are still held in cache then the computer will use the cache version to save time rather than download afresh. It also allows previously visited pages to be viewed offline. What is Cache
