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.
