Study Notes
Computer Networks
- A computer network is a connection between two or more network devices to share network resources.
- The establishment of a computer network depends on the requirements of the communication channel, which can be wired or wireless.
Types of Networks
- Classified based on geographical coverage:
- PAN (Personal Area Network)
- LAN (Local Area Network)
- MAN (Metropolitan Area Network)
- WAN (Wide Area Network)
Local Area Network (LAN)
- Designed to connect multiple network devices and systems within a limited geographical distance.
- Attributes:
- Higher data transmission speed compared to MAN and WAN.
- Uses private network addresses for network connectivity.
- Uses cables for network connection, ensuring data security.
- Advantages:
- Relatively higher data transmission speed.
- The Network Server acts as a central unit for the whole network.
- Disadvantages:
- Requires constant administration by experienced engineers.
- Risk of sensitive data leakage by LAN administration.
Metropolitan Area Network (MAN)
- Covers the network connection of an entire city or small area.
- Attributes:
- Network covers an entire town area or a portion of a city.
- Data transmission speed is relatively high due to the installation of optical cables and wired connections.
- Advantages:
- Provides Full-Duplex data transmission in the network channel.
- Covers an entire city or some parts using optic cables.
- Disadvantages:
- High probability of attack from hackers and cybercriminals.
- Requires good quality hardware and high installation cost.
Wide Area Network (WAN)
- Designed to connect devices over large distances, such as states or between countries.
- Attributes:
- Connection is wireless in most cases and uses radio towers for communication.
- Can be made up of multiple LAN and MAN networks.
- Data transmission speed is lower compared to LAN and MAN networks due to the large distance covered.
