ITEC325 Final Study Guide True/False Indicate whether the sentence or statement is true or false. ____ 1. The value of layers in the OSI reference model is that it divides networking into a series of tasks‚ and then illustrates how those tasks relate to each other. ____ 2. When transmitting with FHSS‚ if interference is encountered on a particular frequency then that part of the signal will be retransmitted on the previous frequency of the hopping code. ____ 3. Increasing the

deal with all security threats in one place which is very difficult. Having your application distributed to layers makes it much easier for design and implement 3. What is a protocol and why would one be used? Provide an example of a technological protocol or a society-based protocol. A Network Protocol Rules of Network Protocol include guidelines that regulate the following characteristics of a network: access method‚ allowed physical topologies‚ types of cabling‚ and speed of data transfer. Some

NS2 has continuously gained tremendous interest from industry‚ academia‚ and government. Having been under constant investigation and enhancement for years‚ NS2 now contains modules for numerous network components such as routing‚ transport layer protocol‚ application‚ etc. To investigate network performance‚ researchers can simply use an easy-to-use scripting language to configure a network‚ and observe results

team member. All network hardware will be protected from loss of power by a UPC. Data Link Layer Assurance and availability are the security goals for this OSI layer. One vulnerable area in this layer is alteration of the Address Resolution Protocol (ARP) cache causing MAC addresses to be matched up to incorrect IP’s. MAC address filtering will be used to identify stations by address and cross-reference the physical port or logical access. Network Layer The network layer is responsible

USER DATAGRAM PROTOCOL(UDP): The User Datagram Protocol(UDP) is called a connectionless‚ unreliable transport protocol. It does not add anything to the services of IP except to provide process to process communication instead of host to host communication. USER DATAGRAM: UDP packets‚ called user datagrams‚ have a fixed size header of 8 bytes. The below diagram shows the format of a user datagram. User datagram format: Source port number: This is the port number used by the process

chance of data “colliding” during transmission. Utilizing MAC protocol‚ a devise will “listen” for other traffic between connected devises. If no traffic is detected‚ the device will pause (an added security against devices sending at the same time) and then send the data in the form of MAC protocol frames.

state. This layer also checks to see if the layers are in the right order when received and not in duplicated form. If there is an error in one of the packets there is a request for that packet’s retransmission. There are two protocols that sit at this layer. First‚ the TCP protocol connects the sender and the receiver using a socket which is determined by the IP address and port number. TCP keeps track of the packet delivery order and which ones need to be resent. UDP on the other hand is a connectionless
