source 14. What is the difference between a static and a dynamic routing protocol?Static routing protocol is of limited use for campuswide network routing but is essential when configuring the default route on router but dynamic routing protocols enable the router’s routingtable to be dynamically updated toaccount for loss or canges in routes or changes in data traffic. 15. What are the four key issues in dynamic routing protocols?Path determination‚ Metric‚ Convergence‚ Load Balancing 16. Define

Introduction They are numerous protocols and standards that are used for communications over networks. But only a few protocols are cryptographic in nature. Cryptographic protocols provide secure communication between two communicating entities over the insecure network. Cryptographic protocols use either symmetric or asymmetric or a combination of both the algorithm to secure the communication channel. Presented in this paper are various cryptographic protocols that provide encryption to data in

Dynamic Host Configuration Protocol (DHCP) "The Dynamic Host Configuration Protocol (DHCP) is a network protocol used to configure devices that are connected to a network (known as hosts) so they can communicate on that network using the Internet Protocol (IP)." [1] When a computer uses a static IP address‚ it means that the computer is manually configured to use a specific IP address. One problem with static assignment‚ which can result from user error or inattention to detail‚ occurs when two

Checkpoint: OSI Model Paul Tegner IT/242 April 22‚ 2011 Mark Burke OSI Model The OSI Model consists of seven layers. These layers are the application layer‚ presentation layer‚ session layer‚ transport layer‚ network layer‚ data link layer‚ and physical layer. The Application Layer The application layer is responsible for interaction between the operating system and the network services and provides an interface to the system. It provides the user interface to a range

and is implementing initiatives to curb the environmental problem. The government calls for the communities to implement 3R - reduce‚ reuse and recycle - at home. For example‚ the community can reduce the use of disposable goods waste such as tissue paper and plastic bags. Besides that‚ drink bottles‚ old newspapers and unwanted clothes can be reused and products which can be used to make compost can be recycled. Therefore‚ as a responsible community we must have a high awareness of environmental hygiene

Message Protocol (ICMP) is one of the core protocols of the Internet Protocol Suite. It is chiefly used by the operating systems of networked computers to send error messages indicating‚ for example‚ that a requested service is not available or that a host or router could not be reached. ICMP can also be used to relay query messages. It is assigned protocol number 1. ICMP differs from transport protocols such as TCP and UDP in that it is not typically used to exchange data between systems‚ nor is
