Definition of Computer Networking

Computer networking is the technology that allows devices to exchange information through a network

Key Elements of a Network

Transmitters and Receivers

Transmitters send data while receivers accept it in a network

Transmission Media

Data travels through a network in the form of electrical, optical, or radio signals

Analog and Digital Channels

Channels in a network can be either analog or digital, and their efficiency is determined by bandwidth and latency

Performance of a Network

The performance of a network is determined by its bandwidth and latency

Categorization based on Geographic Scope and Purpose

Computer networks are classified based on their size and intended use

Local Area Networks (LANs)

LANs are used to connect a small number of devices within a confined area

Wide Area Networks (WANs)

WANs span larger distances and can connect devices across cities, countries, or globally

Intermediate Nodes in WANs

Routers and switches are used to manage data traffic in WANs

Other Types of Networks

Personal Area Networks (PANs)

PANs connect devices within an individual's workspace

Campus Area Networks (CANs)

CANs are larger than LANs but smaller than MANs

Metropolitan Area Networks (MANs)

MANs cover a city or metropolitan area

Definition of Communication Protocols

Communication protocols are a set of rules that govern data exchange between devices

Types of Communication

Simplex Communication

Simplex communication allows data to flow in only one direction

Half-Duplex Communication

Half-duplex communication allows data to flow in both directions but not simultaneously

Full-Duplex Communication

Full-duplex communication supports simultaneous two-way data transmission

Importance of Security in Communication

Security is crucial in communication to prevent unauthorized access and data breaches

Use of Cryptography in Secure Data Transmission

Cryptography is commonly used to encrypt data for secure transmission

Definition of Communication Studies

Communication studies is an interdisciplinary field that examines the processes and effects of communication

Topics Covered in Communication Studies

Technical Aspects of Communication

Communication studies covers the technical aspects of message transmission

Semiotics

Communication studies also investigates the interpretation of signs and symbols

Communication Models

The field explores different communication models and their effectiveness

Role of Communication in Society

Communication studies examines the impact of communication on society

Psychological Aspects of Communication

The field also delves into the psychological factors that influence how messages are received

Importance of Communication Studies

Communication studies provides insights into the evolution of communication technologies and their societal impacts
