The reason why information is stored like this is so that only the information that is needed for specific functions can be used. people: The first group of people we are going to look at play a role in designing, developing, and building information systems. These people are generally very technical and have a background in programming and mathematics. hardware: software: Application software  are programs that direct the performance of a particular use, or application, of computers to meet the information processing needs of end users. They include  A off-the-shelf @  software such as word processing and spreadsheet packages, as well as internally or externally developed software that is designed to meet the specific needs of an organization. telecommunications. many MIS may are delivered acros...

network models OSI model and TCP/IP a OSI model is a conceptual framework for understanding relationships. the purpose of the OSI reference model is to guide vendors and developers so the difital communication products. the physical layer (layer 1) layer 1 of the OSI model is named the physical layer because it is responsible for the transmission and reception of wire level. for example, the physical layer is where it is dictated how bits are represented across a specific networking medium. the data link layer (layer 2) layer 2 of the OSI model is named the data link layer and is responsible for link establishment and termination, frame traffic control, sequencing, acknowledgement, error checking, and media accress management. the network layer (layer 3) layer 3 of the OSI model is named the network layer and is where routing of network traffic begins. the network layer not only makes the traffic routing decisions but also provides traffic control, fragmentation, and logica...
