Tcip and Ip Protocols
The factors that account for the success and popularity of TCP/IP are integrated addressing system, design for routing, underlying network independence, scalability, open standards and development process, and university. TCP/IP includes within it a system for identifying and addressing devices on both small and large networks. Unlike some network layer protocols, TCP/IP is specifically designed to facilitate the routing of info over a network of arbitrary complexity. TCP/IP operates primarily at layers three and above, and includes provisions to allow it to function on almost any lower layer technology, including LANs, wireless LANs, and WANs of various sorts. One of the most amazing characteristics of TCP/IP is how scalable its protocols have proven to be. The TCP/IP standards are not proprietary, but open standards freely available to the public. Everyone uses TCP/IP because everyone uses it.
2. Name and describe the central TCP/IP protocols. Correlate each of these protocols with the layer of the OSI model where they operate.
3. Name, describe, and compare and contrast the two addressing schemes for TCP/IP. Give an example of each addressing scheme. Why are there two addressing schemes?
Networks recognize two kinds of addresses which are logical and physical addresses. Logical addresses are network layer and physical addresses are MAC. MAC addresses are assigned to devices NIC at the factory by its manufacturer. Logical addresses can be manually automatically assigned and must follow rules set by the protocol standards.
4. What is a subnet mask, what is its purpose, and what are the default subnet masks associated with each class?
A subnet mask is a special 32-bit number that when combined with a devices IP address, informs the rest of the network about the segment or network to which the device is attached. Subnet masks are composed of four octets and can be expressed in either binary or
