OSI ( Open system Interconnection ) Reference Model The OSI was released in 1984 AD a standard network model. It decrease how information make its way from application program. Thus media to another application program in another computer. The OSI reference model is described below: 1. Application layer It is service layer . It is closest to the user. It provide services to application program. It synchronizes the sending & receiving application. It determines weather the sufficient resources of the intended communication. 2. Presentation layer It is six layer . It ensure that information send by application layer of one system will be readable by the application layer of another system. It provide common format for transmitting data across various system. so, that data can be understand . It provides facilities to convert meaning to communicating application layer entities. It may perform such transformation as recording, decoding, code conversion, compares

Network Devices Introduction: Network devices are components used to connect computers or other electronic devices together so that they can share files or resources like printers or fax machines. Devices used to setup a Local Area Network (LAN) are the most common type of network devices used by the public. A LAN requires a hub, router, cabling or radio technology, network cards, and if online access is desired, a high-speed modem. Happily this is much less complicated than it might sound to someone new to networking. In a network, one computer is designated as the server, and the others, clients. The server is connected to an external hub, which the clients are also connected to. Now that the computers each have one foot in a common electronic door (the hub), they can use the hub to pass signals back and forth. To direct these signals, the hub contains a device known as a router. The router is the equivalent of an electronic traffic cop that handles data traffic between the co
