Reginald Monroe-@02516632 Summary of OSI layers & Security OSI stands for Open Systems Interconnection and it was developed by the Europeans in the 1980’s. OSI is divided into two major fields‚ an abstract model of networking and a set of defined protocols. The seven layers of the OSI basic reference model are listed and defined below (from bottom to top): 1. The Physical Layer – this layer describes the physical components of the various communications media‚ it also includes the electrical

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

The OSI model is a protocol stack where the lower layers deal primarily

SECTION 2. OPERATION 2.1 INTRODUCTION The KFC Programmable Controller has two fundamental modes of operation: cook and program. In the cook mode the melt‚ stand-by‚ heat‚ and timer functions are active. In program‚ these modes are set by the operator. Melt Indicator - The display will read “LO” when the control is in the automatic melt mode. If the temperature of the shortening is below 185º the control will enter the melt mode. When the temperature of the shortening reaches 185º hte control will

(LAN) is a network of computers that interconnects computers in a limited or a small area such as a home‚ computer lab‚ school‚ or office building using the network media. The defining characteristics of LANs‚ is in contrast to the wide area networks (WANs)‚ including their higher data-transfer rates‚ smaller geographic area‚ and lack of a need for leased telecommunication lines. ARCNET‚ Token Ring and other technology standards have been used in the past‚ but Ethernet over twisted pair cabling‚ and

This value can serve as the secret key shared by A‚ B and C. The values α‚ β and γ should be deleted at the end of the protocol run. 2.3.3 Joux’s Protocol Joux[45]proposed a very simple and sophisticated one-round protocol in which the secret session key for three partners could be generated in a single round using three

Management Program (IDMP) Assignment Kyoto Protocol The Kyoto Protocol to the United Nations Framework Convention on Climate Change (UNFCCC) is an international treaty consisting of obligations on industrialized countries to reduce emissions of greenhouse gases(GHG). The main aim of this protocol is preventing dangerous anthropogenic humaninduced interference of the climate system. 191 countries world over are the members of this protocol. The Protocol was adopted by Parties in 1997‚ and entered

Difference between OSI model and TCP/IP model The Internet Protocol Suite also known as TCP/IP is the set of communications protocols used for the Internet and other similar networks. It is named from two of the most important protocols in it: the Transmission Control Protocol (TCP) and the Internet Protocol (IP)‚ which were the first two networking protocols defined in this standard. IP networking represents a synthesis of several developments that began to evolve in the 1960s and 1970s‚ namely

------------------------------------------------- Address Resolution Protocol The Address Resolution Protocol (ARP) is a computer networking protocol for determining a network host’s link layer or hardware address when only its Internet Layer (IP) or Network Layer address is known. This function is critical in local area networking as well as for routing internetworking traffic across gateways (routers) based on IP addresses when the next-hop router must be determined. ARP was defined by RFC
