ADA NETWORK PADAMA....

[kassaD]

Your definitions are wrong.This is what a network student shouldn't say bro.

A Network is 2 or more devices connected together to share data/information.
Does not matter simplex,half duplex or full duplex.
Then there are network types categorized or divided according to their size,geographic area ......
# LAN/MAN/WAN
#OS based/Device based
#software based/Hardware based

The devices(nodes) are not meant to be computers at all.They could be IP phones,network printers,KVM switches etc.

I had a huge debate for the definition of LAN and I came up right.My professor too agreed for this definition of LAN.

LAN is connecting 2 or more devices in a single network.

zCexVe 2009

So a router separates a LAN for its own.
Say you got a direct satellite link to your own office from home.(People have)
Its a LAN.you would call it a LAN.So the definition is a LAN is alwaysbehind a router.It creates LANs.

Please continue.I'll support you where I can.

First bulid the theories right and straight.It takes like hours to understand so simplify and add them.

OSI is the way you should go.

before go to osi i shoud define da basic ne?

before go to osi i shoud define da basic ne?

If I know correctly OSI is THE Basic

Those 7 layers(Lets forget the TCP/IP practical 4 layer model for now) define how it is organized,what happens,which belongs to what , the simple way.

You should be simplifying those from bottom to top in my opinion but it is always from top to bottom.

I don't know,you can throw in some stuff from here and there but if you look closely each will be in a layer of those 7.You started with topologies.That is Data Link layer,OSI 2 right?

Begin with the hardware.Layer 1.(Its only a suggestion and this is your thread,you have your wish)

hmm its ok bro...i need some one for help so keep post your stuff bro...it will be better for those who reading dis

I don't think I will keep posting. I just wanted to show you that it is hard in networking,and you should be dedicated and do your research on it.Nothing offensive just helping you to get an idea.Because in teaching,if you are wrong , you will not succeed

keep up the good work.You into cisco or just a degree?

ada padama OSI model

The OSI model (Open Systems Interconnection Reference Model)

OSI model was designed by the International Organization for Standardization (ISO). it divides network architecture into seven layers which, from top to bottom, are the Application, Presentation, Session, Transport, Network, Data-Link, and Physical Layers. It is therefore often referred to as the OSI Seven Layer Model.

thankx
keep updating

ada padama Application layer

Application layer
This layer is the main interface for the user to interact with the application.and closest to the end user, which means that both the OSI application layer and the user interact directly with the software application. This layer interacts with software applications that implement a communicating component.Application layer protocols are used to exchange data between programs running on the source and destination hosts
Some examples of application layer implementations include Telnet, File Transfer Protocol (FTP), and Simple Mail Transfer Protocol (SMTP).

protocol=protocol is a formal set of rules, conventions and data structure that governs how computers and other network devices exchange information over a network

ada padama Presentation layer

Presentation layer
The Presentation Layer is responsible for the delivery and formatting of information to the application layer(upper layer we discussed before)for further processing or display. It relieves the application layer of concern regarding syntactical* differences in Data representation within the end-user systems.

1.data format and display
e.g. Fonts, tabs and line and page breaks

2.Code
e.g. ASCII*, EBCDIC*, Unicode, HTML

3.code conversion
e.g. HTML to ASCII*

4.text compression and decompression
e.g. WinZip

The presentation layer is also concerned with data encryption and data security.

*ASCII=American Standers Code for Information Exchange
*syntax=Software related to this layer perform
*EBCDIC=Extended Binary Corded Decimal Interchange Core
