Data Communication and Networking Basics
This tutorial should teach you basics of Data Communication and Computer Network (DCN). **Network Basic Understanding :- A system of interconnected computers and computerized peripherals such as printers is called computer network. This interconnection among computers facilitates information sharing among them. Computers may connect to each other by either wired or wireless media. ** Computer Networks ** Types of Computer Networks ** Topologies ** Types of Topologies

OSI Model & TCP/IP Model (Data Communication and Networking)
OSI or Open System Interconnection model was developed by International Standards Organization (ISO). It gives a layered networking framework that conceptualizes how communications should be done between heterogeneous systems. It has seven interconnected layers. The seven layers of the OSI Model are a **physical layer, **data link layer, **network layer, **transport layer, **session layer, **presentation layer, and **application layer.

Data COmmunications and Networking
Data – refers to information presented in whatever form is agreed upon by the parties creating and using the data. Communication – process of exchanging information “Data Communications are the exchange of data between two devices via some form of transmission medium.” For data communications to occur, the communicating devices must be part of a communication system made up of a combination of hardware (physical equipment) and software (programs).

Introduction to Digital Transmission
Digital-to-Digital Conversion Analog-to-Digital Conversion Transmission Mode Involves three techniques: Line coding (always needed), block coding, and scrambling Line coding: the process of converting digital data to digital signals Data rate defines the number of data elements (bits) sent in 1s: bps Signal rate is the number of signal elements sent in 1s: baud Data rate = bit rate, signal rate = pulse rate, modulation rate, baud rate S = c x N x 1/r, where N is the date rate; c is the case factor, S is the number of signal elements; r is the number of data elements carried by each signal element Although the actual bandwidth of a digital signal is infinite, the effective bandwidth is finite The bandwidth is proportional to the signal rate (baud rate) The minimum bandwidth: Bmin = c x N x 1/r The maximum data rate: Nmax = 1/c x B x r
DATA COMMUNICATION BASIC KNOWLEDGE
BASIC OBJECTIVE: 1. To introduce fundamental communication models. 2. To discuss various time domain and frequency domain concepts of data communication Data Transmission: Communication model Simplex, half duplex and full duplex transmission - Periodic Analog signals: Sine wave, phase, wavelength, time and frequency domain, bandwidth - Digital Signals; Digital data Transmission:- Analog & Digital data, Analog & Digital signals, Analog &Digital transmission – Transmission Impairments: Attenuation, Delay distortion, Noise - Channel capacity: Nyquist Bandwidth, Shannon's Capacity formula

Noise less and noise channel protocols
Noise less channels are divided into 2 types they are simplest channel and stop and wait Noisy channels are divided into 3 types They are. 1.stop and wait ARQ 2.Go.back-N-ARQ 3.selective repeat ARQ

Multiple Access -Data Communications
It consists of typed notes of Multiple Access. It is shared with me by a student studying at FCRIT, Vashi, and I thought of uploading it here so that the students of first and second-year IT Engineering would benefit a lot from it. Thank You! Enjoy learning.

Data communications and networking
Data Communication & Computer Network. Data communications refers to the transmission of this digital data between two or more computers and a computer network or data network is a telecommunications network that allows computers to exchange data.
