Answer the following questions - Admission/Application Essay Example

Answer the following questions Question The OSI strategy grew out of a necessity for international networking principles and is deliberated to facilitate interaction between software and hardware systems despite variances in underlying architectures (Blank 23). The OSI has generated a standard for communication among mechanical devices. Because of this a principle protocol for interaction between almost all computers has become simpler. The OSI framework has also assisted in the expansion of network communications by generating a standard for other gadgets like laptops, and palm pilots that are also able to link to local a wide area networks since the innovations of the OSI model.

The model has also assisted in the expansion of network communications via its creations of principle protocols for internet access. This has facilitated for many innovation and developments in WAN’s (Blank 23).Question 2Unicast comprises a one-to one link between the server and the client. Unicast employs IP delivery techniques such as TCP and UDP (User Datagram Protocol), which are session-oriented protocols. While Multicast is a factual broadcast; the multicast basis relies on multicast-activated routers to promote the packets to all respective subnets that have clients’ attentions.

There is no straightforward relationship between Windows Media server and the clients (Blank 28).Question 3The sending host can convey only up to that quantity of data available it must wait for a recognition and window update from the in receipt of host. So window size influence the flow control since it has to update sending host for another flow o be initiatedQuestion 4In an end-end approach towards congestion control; the layer (network) gives no explicit enforcement to the transport layer for blocking control purposes.

  Even the existence of congestion in the system must be contingent by the end systems oriented only on experimental network behavior such as delay and packet loss. Network-assisted congestion control; with network-support congestion control, network-layer equipments such as routers provide clear feedback to the sender concerning the congestion condition in the network.Question 5The normal procedure of establishing a link between a TCP client and server comprises three stages: the client sends a SYN message; the server passes a message that incorporates an ACK for the client’s SYN and has the server’s SYN; and afterward the client submits an ACK for the server’s SYN.

This is known as the TCP three-way handshake and essential for connection establishment and closure (Blank 50).Question 6The session layer gives the process for opening, closing and controlling a session between end-user application procedures such as a semi-permanent conversation.Question 7In Stop-and-Wait protocol, flow control is attained by compelling the sender to await an acknowledgment, and error control is accomplished by discarding spoilt packets and allowing the sender re-conveys unacknowledged packets when the clock expires.

This is done at the transport layerQuestion 8Presentation layer perform the following data handling issues translation of network data, compression and decompression, and encryption.
