Difference between DVD-R and DVD+R
DVD-R and DVD+R are two different formats for recordable DVDs. The main difference between them lies in the technical specifications and the companies that supported each format when they were introduced.

Basic OSPF Configuration, Step by Step
OSPF short for Open Shortest Path First is a Routing Protocol used to select the best suitable route for packets within the network. OSPF basically an open standard protocol and not relate to any particular vendor. OSPF propagate the changes to all networks more quickly as compared to RIP and IGRP protocols then only send the changed part… Read More »
Application Layer Details
The application layer is the seventh level of the seven-layer OSI model. It interfaces directly to and performs common application services for the application processes; it also issues requests to the presentation layer.
Presentation Layer Details
The presentation layer is the sixth level of the seven layer OSI model. It responds to service requests from the application layer and issues service requests to the session layer.
Introduction to Network Protocols
The word protocol is derived from the Greek word “protocollon” which means a leaf of paper glued to manuscript volume. In computer protocols means a set of rules, a communication language or set of standards between two or more computing devices. Protocols exist at the several levels of the OSI (open system interconnectivity) layers model. In the telecommunication… Read More »
LLC Sublayer Details
According to the IEEE 802 family of standards, Logical Link Control (LLC) is the upper sublayer of the OSI data link layer. The LLC is the same for the various physical media (such as Ethernet, token ring, and WLAN).
MAC Sublayer Details
The Media Access Control (MAC) data communication protocol sub-layer, also known as the Medium Access Control, is a sublayer of the data link layer specified in the seven-layer OSI model (layer 2). It provides addressing and channel access control mechanisms that make it possible for several terminals or network nodes to communicate within a multipoint network, typically a… Read More »
Transport Layer Details
In computing and telecommunications, the transport layer is the second highest layer in the four and five layer TCP/IP reference models, where it responds to service requests from the application layer and issues service requests to the network layer. It is also the name of layer four of the seven layer OSI model, where it responds to service… Read More »
Network Layer Details
The network layer is the third layer out of seven in the OSI model and the third layer out of five in the TCP/IP model. In the TCP/IP reference model it is called the Internet layer. In all of the models, the network layer responds to service requests from the transport layer and issues service requests to the… Read More »
Data Link Layer Details
The data link layer is layer two of the seven-layer OSI model as well as of the five-layer TCP/IP reference model. It responds to service requests from the network layer and issues service requests to the physical layer.
