Logical and Physical Network Design Logical and physical network designs are critical components in the successful development and implementation of today ’s networks and allow for the proper planning and structuring bettering enhancing the concept associated with networks. In order to better understand how the two concepts of a logical design and physical design work hand-in-hand‚ let ’s first look at what the concepts entail. A logical design is a concept‚ thought or theory as to how you

MIS 374 Rev 02 Process Modeling: Context Diagrams and Data Flow Diagrams (DFDs) Introduction Figuring out the business processes for complex systems can be complicated. For example‚ if the goal is to streamline an existing supply chain process‚ your investigation will cross multiple business units‚ perhaps starting with an on-line order‚ a retail store pick-up‚ or a telephone order. How does the current process work to replace items in inventory storage and on retail shelves? Computer systems

INTRODUCTION TO NETWORK TYPES Research Paper #1 Prepared for Professor Jewett Prepared by Anissa Truitt COOP Semester: Spring 2007 The article basically describes the different types of networks. It states "nearly every type of design is referred to as an ¬area network". The main networks discussed are‚ LAN and WANs. According to the article‚ these were the original categories of area networks. LAN‚ which stands for Local Area Network‚ connects devices over a relatively short

people in various places. Companies can get many advantages by using Internet network to support their business. Therefore‚ companies are trying as hard as they can‚ and give high effort in protecting their network from attack and make sure that they have the best network security. Most people think that the threat of security attack is only come from outside the company. In fact‚ the attack from inside the company network is more harmful with high frequency to be happened.
