The process of Intranet in the field of IT technology by Kh. Atiar Rahman

The information bank tree intimately look a lot like the way we store files on our hard drive in a main directory with subdirectories leading to files. We could also think of the hierarchy as a representation of an actual tree. If we invert the tree, the trunk of the tree would be the top level of the publication. The trunk could be the overview of the publication. The large boughs leading from the trunk would be the next level of the document structure. The boughs could be chapter overview pages. Branches leading from the boughs would be the next level, or the pages within chapters. A combined linear and hierarchical structure is one of the most used forms for hypertext publications. This is because it is an extremely flexible, but still highly structured method. Readers can move forward and backward through individual pages. They can navigate through the various levels of the publication by moving up a level or descending to the next level. They can also follow parallel paths through the document. The most complex structuring method is the integrated web. This method lets the reader follow manifold paths from many options. This is a good method to use when we want the reader to be able to browse or wander many times through the publication we have created. Each time through the publication, readers will probably discover something new. After considering the various styles for hypertext documents, we should examine the various tools we will need to develop the intranet. A tool is anything that supports the task we are working on. The tools for unleashing the power of our intranet are based on the existing tools for the Internet itself, which includes protocols, resource tools, and information services. TCP/IP (Transmission Control Protocol Internet Protocol) is the foundation of the worldwide Internet. We must install TCP/IP on our network to enable intranet services. A protocol is a set of rules for programs communicating on the network. It specifies how the programs talk to each other and what meaning to give to the data they receive. Without TCP/IP setting the rules for our network communications, we cannot use Internet technologies. Suffice it to say that if our organization already has access to the World Wide Web; we might already have the necessary TCP/IP configuration in place. Furthermore, TCP/IP is built into some operating systems, including Windows 95, Windows NT, and most variants of UNIX. If we have an operating system where TCP/IP is not built in and do not have TCP/IP installed, we will need to purchase TCP/IP software. Fortunately, TCP/IP software is widely available from software vendors.

An intranet without Web services is like a world without water. The key to the World Wide Web is the hypertext transfer protocol. HTTP offers a means of poignant from document to document, or of indexing within documents. Accessing documents published on our intranet involves communications between browsers and servers. In a browser, such as the Netscape Navigator, the HTTP processes are virtually transparent to the user. All the user really has to do is activate links to move through our Web presentation. The browser takes care of interpreting the hypertext transfer commands and communicating requests. The mechanism on the receiving end, which is processing the requests, is a program called the Hypertext Transfer Protocol Daemon (HTTP). A daemon is a UNIX term for a program that runs in the background and handles requests. The HTTP daemon resides on our Web server. Before setting up or installing server software, we must determine what platform the Web server will run on. Until recently, our choices were limited, but this changed rapidly as the World Wide Web grew in attractiveness. Today, Web server software and server administration tools are available for almost every platform. And, like other software developed for use on the Internet, this software is available as freeware, shareware, and commercial software. We will find that UNIX platforms have the most options for server software. Until recently, there was only one good choice for the Windows NT environment, but this has changed. There are now many excellent commercial and freeware choices for Windows NT. For other platforms, there is generally only one choice in server software. Having only one choice of server software for the Windows system which doesn’t mean the quality of the server software is poor. Quite the contrary, the quality of the software is often quite good. Tools are an essential part of any operation. Resource tools provide the means for sending and retrieving information. There are three basic tools of intranet wor
