Application architecture and Process Design:- Applications are designed according using a system development life cycle‚ which passes through several phases including requirements gathering‚ design‚ implementation‚ testing‚ and maintenance. We describe the application design process by designing an information system for Riordan Manufacturing‚ Inc.‚ an industry in the field of plastic injection moulding. The first step of design is to identify the processes and the entities. Processes represent

networks. The characteristics‚ components‚ and topology are evaluated to properly identify the needs for the new network design. The plan includes converting to a Wireless Local Area Network otherwise known as (WLAN)‚ installing a Voice over Internet Protocol otherwise known as (VoIP)‚ and design a Wide Area Network (WAN). The plan also includes the hospital maintaining all Macintosh® computers. Administration/Clinical Overview * The administrative departments run off of a 1000 Base-T Ethernet

According to PC Magazine‚ overhead is the amount of processing or transmitting time used by the system software‚ database manager or network protocols that trans mits additional codes in order to control and manage the data transfer over the network (PC Magazine). Keep in mind‚ when assessing the performance of networks there is always a difference between theoretical speed ratings‚ and real world

what is a Router‚ why we need Routers‚ what is the importance of a Router. We also learned what VLSM is and how to do it and use it. Throughout CCNA we learned how to configure a Router; the different types of Routing protocols and most importantly what‚ when and how to use those protocols in the field. Finally I will discuss Switches in how they are use to set up a LAN. Throughout this paper these topic will be discuss to cover what was learned through class lecture and text book (CCNA study guide

Assume the operating system in the destination host has assigned a 4-byte port number to each running application process. b. Modify this protocol so that it provides a “return address” to the destination process. c. In your protocols‚ does the transport layer “have to do anything” in the core of the computer

In a P2P network‚ the "peers" are computer systems which are connected to each other via the Internet. Files can be shared directly between systems on the network without the need of a central server. In other words‚ each computer on a P2P network becomes a file server as well as a client. P2P allows us to search for files on other people’s computers
