UNIX ARCHITECTURE The architecture of UNIX is divided into three levels. On the outer crust reside the Application Programs and other utilities. At the heart of UNIX‚ on the other hand‚ is the Kernel‚ which interacts with actual hardware in machine language. The stream lining of these two modes of communication is done by the middle layer called Shell. Thus the three basic layers are:- ✓ HARDWARE ✓ KERNEL ✓ SHELL At the core is the physical

Dependencies and Network Diagram The network diagram is a schematic representation showing the sequence and relationship/ dependency of the tasks along with their duration. All the tasks‚ except the first and the last‚ are linked with at least one predecessor and successor to have a proper sequence of work. This logical dependency between the tasks will determine afterwards the duration of the project. There are four types of dependencies which define the relation between pair tasks Finish-to-start

Functional Decomposition Diagram An analyst first must understand an organization’s business functions before he or she can begin developing information systems. The functional decomposition diagram (FDD) is a business planning tool that depicts the hierarchy of business functions‚ processes‚ and subprocesses within an organization that are later described in detail using process models (chapter 6). The exercise of breaking down‚ or decomposing‚ the business functions into processes makes complex
