Applications - Local and Network

three different operating system pictures.

three different network applications

jurnal entry

Activity 3 ( 1-27-2010) On this journal we learn the differences of applications and what are the inputs and out puts and how to put on our blog to show how they work.

inputs:
Mouse, monitor, keyboard

outputs:
digital camera, scanner, printe

introduction

Will we compare how the OSI and TCP/IP work and how they are diffrent each other and hoe they work.

Comparing OSI and TCP/IP

Journal

On this activity will have to know about the differences about OSI and TCP/IP well was easy because we find all of this on the Internet and how they are different and what are the things that haven in common.

Vocabulary

Physical Layer
The physical layer may be either ethernet, SDH-DCC, or some timeslot of a PDH signal. Either OSI protocols and TCP/IP protocols build on the same physical layer standards, thus there is no difference between OSI and TCP/IP in this aspect.

Data Link Layer
The purpose of the data link layer is to provide error free data transmission even on noisy links. This is achieved by framing of data and retransmission of every frame until it is acknowledged from the far end, using flow control mechanisms. Error detection is done by means of error detection codes.

Network Layer
The network layer provides routing capabilities between source and destination system

Transport Layer
The transport layer provides a reliable end-to-end connection between source and destination system on top of the network layer. It builds an integral part of the whole OSI layering principle and of the internet protocol.
