Analyze the necessity for different protocols in wireless communications. An agreed upon guidelines or set of rules for communication is called as protocol. It is very important to agree upon some communication rules otherwise it will fail. If one party speaks French and the other German the communication would surely fail. If they both agree on a single language they can communicate successfully. The set of communication use don internet is called as TCP/IP. A protocol can be defined as rules that

without the need for intermediate devices such as routers. 5. Network Layer 6. Gateway describes the networking device that enables data to enter and exit a LAN, and is where the host computers forward data packets that need to exit LAN. 7. TCP/IP protocol 8. The packet will stay in the LAN because the destination IP address is in the same network as the host IP address and therefore has no need for forwarding or routing. 10. The destination subnet address for 255.0.0.0. which is different subnet

DAYSTAR UNIVERSITY An assignment IN PARTIAL FULFILLMENT TO THE COURSE ACS 431 Presented by: Gladys Mumbua (10-1809) Submitted to MR FREDRICK OGOR FIREWALLS A firewall is a device that serves as a barrier between networks providing access control, traffic filtering and other security features. Firewalls are commonly deployed between trusted and untrusted networks, for example between the Internet (untrusted) and an organization’s trusted private various network. They [firewalls] can also

via hardware detection mechanisms. However, the signals from these mechanisms are not always conveyed directly to the upper protocol layers. When the hardware mechanisms do not exist (eg: Ethernet) or when the signaling does not reach the upper protocol layers, the protocols must rely on their much slower strategies to detect failures. The detection times in existing protocols are typically greater than one second, and sometimes much longer. For some applications, this is too long to be useful. Bi-directional

Governments, businesses and individuals, through knowledge of trends, can make decisions and strategic policies most relevant to limit the impacts of climate change. The IPCC reports are the main base of information and discussions and the Kyoto Protocol provides mechanisms (carbon market, clean development, joint implementation) to reduce gases emissions, this one not making the unanimity in different
