Study Notes

Overview of Networks and Communication

Involves connecting systems and devices for data sharing.
Includes hardware (computers, routers, switches, modems) and software protocols for data flow management.
Essential protocols: TCP/IP, HTTP set rules for data exchange.

Definition of a Network

A network consists of devices interconnected by communication links.
Comprises two or more computers, termed as nodes, capable of data exchange.

Types of Networks

Classified into Local Area Networks (LAN), Metropolitan Area Networks (MAN), and Wide Area Networks (WAN).
Wireless networks include Wi-Fi and cellular networks.

Network Criteria

Networks must meet specific criteria for functionality and reliability.

Risks of Network Computing

Networks face security challenges from equipment failures, system failures, natural disasters, and electrical disturbances.

Local Area Network (LAN)

Privately owned, links devices within a limited range (a few kilometers).
Designed for resource sharing in locations like offices or campuses.
Typically utilizes a single type of transmission medium.
Common LAN topologies: bus, ring, star.

Uses of LAN

Facilitates resource sharing among personal computers and workstations.

Metropolitan Area Network (MAN)

Extends connectivity over an entire city.
Links multiple LANs within a geographic area.
May be privately owned or provided by public companies, like local telephone companies.

Uses of MAN

Connects users with resources in areas larger than a LAN but smaller than a WAN.

Wide Area Network (WAN)

Enables long-distance data transmission across countries, continents, or globally.
Connects all an organization's computers and devices for internal resource sharing.

Uses of Network and Communication

Vital in various aspects of modern life, enabling efficient access to information and communication.

Issues Affecting Network and Communication

Performance and reliability may be impacted by various issues within a network environment.

Advantages of Networking

Enhances connectivity, efficiency, and access to information globally.

Disadvantages of Networking

Vulnerable to security risks and potential system failures.

Conclusion

Networking and communication have transformed data exchange through methods such as infrared, radio waves, and satellites.
Development of protocols ensures standardized communication, enhancing global connectivity and efficiency.
