between Logical & Physical Design of a Network When we look at the differences between logical design and physical design of a network it is easy to think of it as the logical as the functional part and physical as the seeing it part. With that stated there is more to this than just the functional and seeing parts. In order to understand the differences from one to the other‚ we need more information. In the following paragraphs I will try to outline what makes up the differences between logical and

Logical Design Logical design takes each piece of conceptual design and assigns it to a specific logical role within architecture. For infrastructure projects‚ the architecture might be a series of block diagrams showing networks‚ service components‚ and network connection elements. Application architecture is typically broken down into at least three levels: presentation‚ business‚ and data level. Because this is a migration project‚ the team should document the existing logical design as well

1.2. ACTIVITIES TIMING AND TOTAL FLOAT To determine timing of activities in the network diagram the following calculations were done for each node: Earliest Start-(ES)‚ Earliest Finish-(EF)‚ Latest Start-(LS) and Latest Finish-(LF). Field and Keller (1998‚ p. 191) ES and EF are found by using the forward pass through the network … from the unique project start node and ends at the unique project completion node. ES is the ending day for the previous node/activity‚ where more than one

among the offices‚ all the computers should be able to view and update the data from any of the three offices. In other words‚ the data storage server within each LAN should be accessible to all computers‚ no matter where they are located. Draw a network diagram that will support this configuration. 3.

The Logical and Physical Design of a Network When a network is being designed‚ the architect must first think about the logical layout and that should be enforced. When he figures out what devices need to communicate and how‚ a physical design of the network can be implemented. A logical design is the reasoning of a network‚ with no particular devices or locations chosen. The physical design of the network is when the devices are picked and their actual location determined. When the logical design

THE DIFFERENCE BETWEEN LOGICAL DESIGN AND PHYSICAL DESIGN OF A NETWORK When comparing the logical and physical design of a network I visualize a carefully thought out plan created from start to finish by the individuals that would ultimately be using and maintaining it. Like many areas in Information Technology‚ Network Design cannot be taken likely. All of the necessary steps like those of the SDLC process must be done step-by-step in order to minimize unnecessary costs‚ downtime and loss of

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

CONVERGENCE OF LOGICAL AND PHYSICAL SECURITY SYSTEMS INTRODUCTION Up to now‚ majority of organizations have their physical and logical access systems operating as independent structures‚ with each being run by a totally separate department. The information technology security system‚ which controls access to information technology infrastructure including mail servers‚ the internet‚ database applications and web servers was managed by the department of information technology. The physical security system

You will also learn how to determine the duration of the project‚ and the critical path. In this homework assignment‚ you will be working through four Activity In Box (AIB) problems. Using the activity‚ duration‚ and predecessor information given in this document‚ you should first construct a network for each "project." [Each problem will have its own network.] Once you
