Study Notes
Computer Networks
- A network is two or more computers or electronic devices connected together to share data and resources.
- Advantages of computer networks:
- Ease of accessibility
- Flexibility
- Convenient resource sharing
- Connectivity
- Great storage capacity
- Reduced cost
- Disadvantages of computer networks:
- Lack of robustness
- Spread of computer virus
- Implementation issues
- Lack of productivity
- Health issues
Classification of Computer Networks
- Local Area Network (LAN):
- A collection of devices connected together in one physical location
- Can be small or large, ranging from a home network to an enterprise network
- Devices are in a single, limited area
- Virtual Local Area Network (VLAN):
- A logical overlay network that groups together a subset of devices on a physical LAN
- Isolates traffic for each group
- Metropolitan Area Network (MAN):
- A computer network that connects computers within a metropolitan area
- Larger than a LAN but smaller than a WAN
- Wide Area Network (WAN):
- A collection of LANs or other networks that communicate with each other
- A network of networks
Internet and Intranet
- Internet:
- A worldwide, publicly accessible series of interconnected computer networks
- Transmits data by packet switching using the standard Internet Protocol (IP)
- A "network of networks" that consists of millions of smaller domestic, academic, business, and government networks
- Intranet:
- A private network contained within an enterprise
- Uses Internet protocols and network connectivity to securely share part of an organization's information or operations with its employees
- Can be understood as "a private version of the Internet"
Extranet
- An extranet is a private network that uses Internet protocols, network connectivity, and possibly the public telecommunication system to securely share part of an organization's information or operations with external parties.
Learn about the basics of computer networks, including advantages and benefits of networking, such as ease of accessibility, flexibility, and convenient resource sharing.
