encryption to data in transit. Secure Socket Layer (SSL): SSL protocol is a cryptographic protocol used for establishing a secure communication channel between two entities (Martin‚ 2012). Secure socket layer operates at the transport layer of the internet protocol suite. Though SSL provides transport layer security‚ it site immediately above Transmission Control Protocol (TCP) in the protocol stack‚ therefore it can be said that the SSL provides session layer security in the OSI model (Kak‚ 2012).

3.1.3 Computer Network Topologies Network Topology is a network specification that determines the network arrangement‚ connecting the senders and receivers through lines of connection. Topologies are of both physical and logical aspect of the network. The physical topology describes the network’s physical wiring layout or shape. The logical topology describes the path through which the data moves. Both logical and physical topologies could be same or different in a same network. The physical and

standards‚ but are used in common practice to reduce the power of devices in both WLANs and WPANs. These techniques exist from the application layer all the way down to the physical layer of a traditional networking protocol stack. Techniques specific to a particular type of network are annotated as appropriate. Application Layer At the application layer a number of different techniques can be used to reduce the power consumed by a wireless device. A technique known as load partitioning allows an

The Sender‚ which runs in the Data Link Layer of the source machine‚ fetch a packet from the Network Layer 2. An outbound frame is constructed 3. Sender remembers the next frame’s sequence number before entering the loop 4. The Sender then sends the frame to the Receiver a. Check: If timer is already running then reset

a message is transmitted from one computer to another using layers? In a network of computers each computer connected must have a unique IP address. IP: 1.2.3.4 IP: 5.6.7.8 When a message is sent from one computer to another‚ it travels down the protocol layers of the model‚ and then up the layers of the stack on the other computer. The application layer is the application software used by the network user. The Transport Layer guarantees that the receiver gets the data exactly as it was
