OSI Model Essay

wireless networks. As the multimedia applications are resource intensive, they are to be used with certain optimizations. The wireless networks are not optimized for such applications. The OSI model was also not designed by keeping multimedia applications in mind. Therefore, individual layers of OSI model can be optimized or jointly they can be optimized. The joint optimization is known as cross layer design (CLD) approach. The cross layer design approach considers two or more layers to be improved

more in the wireless communication domain. Since it is based upon Layer 1 and part of layer 2 OSI Model, it may prove further useful to connect a number of devices. 3. TECHNOLOGY DESCRIPTION The ZigBee technology, has different subdivisions and names and works on the several layers of the OSI model, each having a different name and a distinguished function. This paper focuses on the first two layer of the OSI which is responsible for point-to-point connectivity. The ZigBee technology has an embedded

Introduction to Networking Generally in IT field, networking terminology we hear the term IP address. In general IP address is logical name associated to a personnel computer, laptop, mobile, tablet or any networking enabled PC. As humans talk to each other with the means of name, devices in the networking worlds communicates with each other by means of IP address. Before we learn why we need an IP address, how it works first we will see how this term was emerged and are its associated parameters

process actually consists of series of complicated steps. These steps can be best explained with the help of the Open System Interconnection (OSI) The OSI model was started by the International Organization for Standardization group in 1977. The model is used as a tool for teaching students on how computers communicate over a network. (Wallace, 29-30) The OSI Model consist of seven layers. The seven layers names are the Physical Layer, Data

This paper will attempt to define and contrast the following terms: a.     Synchronous and asynchronous b.     Analog and digital c.     XON and XOFF d.     Simplex and duplex e.     Serial and parallel transmission f.     Baseband and broadband g.     Serial Line Internet Protocol (SLIP) and Point-to-Point Protocol (PPP) h

networking products, many companies are hesitant to support newer technology unless there is a standardization base from which to work. Different types of network standards include 802”LAN”, 802.3 “wired LAN” and 802.11 “Wireless” there is also the OSI model. A network protocol defines a set of rules and conventions between devices. Protocols for a computer network usually use packet switching techniques to send and receive messages in the form of packets. There are different types of Protocols one

2.3 What is a Protocol? Protocol is nothing but set of guidelines, which supports the data exchange between the layers. The guidelines describe what to do (the details like when and where to send the data, data format). 2.4 What is a Protocol Data Unit? Telecommunication protocol create protocol data unit in sender side. This protocol data unit of message is transmitted by using protocol. Each PDU have particular format and contains header information in header information identify protocol type

In the second and third layer of osi model it is called data link and network link. Data link is packaging data into frames and transmitting those frames on the network and performing the error detection correction by uniquely identifying the network devices with an address, and handling

Nowadays everybody can get access to the internet through networks, but according to Columbia University over the 37% of people do not know what a network is. A network is a group of computers which are connected to share information, files, and performs tasks. A network is built using the same common language. My purpose of this project is to explain what a network is, and let you know how important is to know it. The next paragraphs will explain the introduction of networking, the disadvantages

IT388 Unit 1 Assignment and Labs Topologies Professor Walker August 24, 2017 Margaret Webb In a bus topology, all segments are associated with and share a solitary wire. Certain media sorts, for example, 10Base5 and 10Base2 Ethernet, utilize a bus topology. Regularly, unique sorts of connectors or handsets are utilized to interface the links to give the bus topology. In 10Base5, for instance, every gadget interfaces with a solitary strand of the coaxial link by means of a vampire
