Comparison and Contrast between the OSI and TCP/IP Model



Introduction



This presentation would discuss some comparison and contrast between the 2 main reference models which uses the concept of protocol layering.

Open System Interconnection Model (OSI)
Transport Control Protocol /Internet Protocol (TCP/IP)

The Session Layer

The Session layer permits two parties to hold ongoing communications called a session across a network.
Not fou ....etc

OSI REFERENCE MODEL

1. Physical Layer

a) Convert the logical 1’s and 0’s coming from layer 2 into electrical signals.

b) Transmission of the electrical signals over a communication channel.

Main topics:

Transmission mediums
Encoding
Modulation
RS232 and RS422 standards
Repeaters
Hubs (multi-port repeater)


2. Data Link Layer

a) Error control to compensate for the imperfectio ....etc

Introduction

Requirements for removable media storage devices (RMSDs) used with personal computers have changed significantly since the introduction of the floppy disk in 1971. At one time, desktop computers depended on floppy disks for all of their storage requirements. Even with the advent of multigigabyte hard drives, floppy disks and other RMSDs are still an integral part of most computer systems, providing.

Layer Reassignment for Antenna Effect Minimization in 3-Layer Channel Routing


Abstract

As semiconductor technology enters the deep submicron em, reliability has
become a major challenge in the design and manufacturing of next generation
VLSI circuits. .ln this paper we focus on one reliability issue - the antenna
effect in the context of s-layer channel routing. We first present an antenna effect
model in Z-layer channel routing and, based on this, an antenna effect cost
function is proposed. A layer ....etc

SSL is a protocol using different cryptographic algorithms to implement security-using authentication with certificates, session key exchange algorithms, encryption and integrity check. It is a common protocol, often used to ensure that the communication between WWW-server and WWW-client is safe and encrypted.

Digital certificates encrypt data using Secure Sockets layer (SSL) technology, the industry-standard method for protecting web communications developed by Netscape Communications Corporation. The SSL security protocol pro ....etc

It was not so long ago that switches were used in telecommunications primarily for placing telephone calls. Dialing a telephone number activated a series of switches to set up a voice path that could be as simple as the next office or as complex as a multinational conference call. Internetworks and the Internet are beginning to provide similar services for PC workstations, servers, and mainframes. The primary goal of any data network provider is to eliminate geographic and media constraints on connectivity while maintaining control ....etc
