Study Notes
Computer Networks
- Computer networks are connections between two or more devices to share resources and tools.
- They can be classified based on the connection mode, such as wired or wireless.
- They are categorized into different types depending on the requirement of the network channel.
Types of Networks
- Types of networks are classified based on geographical coverage, including:
- PAN (Personal Area Network)
- LAN (Local Area Network)
- MAN (Metropolitan Area Network)
- WAN (Wide Area Network)
Local Area Network (LAN)
- LAN is designed to connect multiple devices within a limited geographical distance.
- Attributes of LAN Network:
- Higher data transmission speed compared to MAN and WAN.
- Uses private network addresses for network connectivity.
- Uses cables for network connection, reducing error and maintaining data security.
- Advantages of LAN Network:
- Higher transmission speed.
- Centralized Network Server.
- Disadvantages of LAN Network:
- Requires constant administration.
- Risk of data leakage.
Metropolitan Area Network (MAN)
- MAN is a network that covers an entire city or a small area.
- Attributes of MAN Network:
- Covers an entire town area or a portion of a city.
- High data transmission speed due to optical cables and wired connections.
- Advantages of MAN Network:
- Provides Full-Duplex data transmission.
- Covers a large area.
- Disadvantages of MAN Network:
- High probability of hacking and cyber attacks.
- Requires high-quality hardware and installation.
Wide Area Network (WAN)
- WAN is designed to connect devices over large distances, such as states or between countries.
- Attributes of WAN Network:
- Lower data transmission speed compared to LAN and MAN.
- Connection is wireless in most cases and uses radio towers for communication.
- Can be made up of multiple LAN and MAN networks.
