Computer Networks Does anyone really know what networking is? “In the world of computers‚ networking is the practice of linking two or more computing devices together for the purpose of sharing data” (Networking Fundamentals). Now this is a great explanation but does this really help us understand? Networking has grown over many years. Where did networking come from? Lets go back to the beginning and find out how far we have come. Network research can be traced back to around the 1960’s.

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 two‚ OSI and TCP/IP are Standardized Protocol Architectures developed specifically for: 1. Devices to communicate 2. Vendors to have more marketable products 3. Customers to insist on standards based equipment The OSI is a reference model whilst TCP/IP is the suite which is the most widely used. Description of Open Systems Interconnection (OSI Model) Developed by the International Organization for Standardization (ISO) It is made up of seven layers and each layer: 1. performs a subset of

Aim: Comparison Between TCP/IP and OSI Reference Model First we discuss‚ what is TCP\IP and OSI model‚ why they are introduced and where they are used. In the following Section OSI Reference models explained with all layers as well as their responsibilities. Open Systems Interconnection model (OSI model): OSI reference model is now considered as a primary standard for internetworking and inter computing. Today many network communication protocols are based on the standards of OSI model. In the

Logical and Physical Network Designs Logical and Physical Network Designs Network planning and design is an extremely important process which must be performed before the establishment of a new telecommunications network. The purpose of network planning and design is to ensure that the new network meets the necessary requirements of the system. The network planning process includes forecasting how the network will operate‚ the economic information concerning costs‚ and the technical details

Logical and Physical Network Design Logical and Physical Network Design Network design is a process that begins from the first thought on how to connect to computers together in order for them to communicate and pass needed data to each other. The process may seem simple on this level and may require little consideration‚ but in fact‚ there are many areas of the network that need to be examined before the process of networking should be undertaken. For the small network‚ these considerations

BUYUKHAN COMPUTER NETWORKS NETWORK TELEPHONY –VOICE OVER INTERNET PROTOCOL(VoIP) VoIP is a set of technologies that enable voice calls to be carried over the internet (or other networks designed for data)‚ rather than the traditional telephone landline system-the Public Switched Telephone Networks(PSTN). VoIP uses IP protocols‚ originally designed for the internet‚ to break voice calls up into digital ‘packets’. In order for a call to take place the separate packets travel over an IP network and
