OSI Model This memorandum will attempt to explain the Open Systems Interconnection Model‚ known more simply as the OSI Model. The OSI Model has seven levels‚ and these levels will be discussed in detail. Particular mention will be made to which level TCP/IP functions with the OSI Model. The seven levels of the OSI Model are as follows: 7) Application: Provides different services to the applications. 6) Presentation: Converts the information. 5) Session: Handles problems which are not communication

OSI Reference Model 1 - OSI Reference Model Network Reference Models A computer network connects two or more devices together to share information and services. Multiple networks connected together form an internetwork. Internetworking present challenges - interoperating between products from different manufacturers requires consistent standards. Network reference models were developed to address these challenges. A network reference model serves as a blueprint‚ detailing how communication

OSI Protocol Hierarchy Session Layer The session layer is the fifth among the seven layers of the Open System Interconnections (OSI) model. It resides above the transport layer and below the presentation layer‚ and provides “value added" services to the underlying transport layer services. The session layer (along with the presentation layer) add services to the transport layer that are likely to be of use to applications‚ so that each application doesn ’t have to provide its own implementation

Authentication Protocol for Vehicular Ad Hoc Networks ABSTRACT Vehicular Ad Hoc Networks (VANETs) adopt the Public Key Infrastructure (PKI) and Certificate Revocation Lists (CRLs) for their security. In any PKI system‚ the authentication of a received message is performed by checking if the certificate of the sender is included in the current CRL‚ and verifying the authenticity of the certificate and signature of the sender. In this paper‚ we propose an Expedite Message Authentication Protocol (EMAP)

Protocol Paper #2- Do we Survive Death? Recall • Socrates thought that the soul is too simple to destroy; he thought that we are indestructible. • Modern science disagrees with Socrates; the idea of the body-and-soul became the idea of the body-and-brain‚ psychology is the new soul; modern science has sees a correlation between consciousness and the brain. • There are three main fields that try to answer life after death- near death experiences‚ reincarnation‚ and psychics. • Near death experiences

United Kingdom’s climate change protocol will be reported and verified through a variety of procedures. Most dominantly‚ England is a proud member of the Kyoto protocol‚ which monitors progress of all the countries involved. The program evaluates all emissions of GHG from each country to find where monitoring of the gases is most necessary. Precise records of emission trading are recorded to ensure the target goal is within reach. To ensure the rules of the protocol are followed‚ the UN Climate

First is to present critical human error infrastructures as complex adaptive systems‚ which share certain characteristics that policy makers and managers need to account for. Secondly‚ the balance of the paper outlines will focus on improvements of the analytical and decision-making complexity‚ and presents the research and policy-making agendas that need to be addressed if we are to significantly

Assignment Week 3 NTC/362 INDP Part 2 December 3‚ 2012 Wanda Pauley The importance of communication protocols: Unless Patton Fuller Community Hospital has an agreement between the two communicating parties information may get lost or un-communicated. This agreement is called the protocol. Communications protocols usually have a number of parts‚ Handshake‚ encoding method‚ compressions methods‚ packet / frame structure‚ and addressing.. This is why protocols are often defined by standards

This presentation was informational about SIOP. I learned that SIOP stands for Sheltered Instruction Observation Protocol Model. Sarah Eakin stated‚ “SIOP is a research-based and validated instructional model that has proven effective in addressing the academic needs of English learned throughout the United States.” SIOP consists of eight components: lesson preparation‚ building background‚ comprehensible input‚ strategies‚ interaction‚ practice/application‚ lesson delivery‚ review and assessment
