Study Notes
Purpose of a Computer Network
- Facilitates communication and resource sharing between multiple devices.
- Allows for data transfer, online collaboration, and access to shared applications.
- Enhances efficiency by enabling businesses to connect various systems and streamline processes.
Hardware Components for Building a Computer Network
- Routers: Directs data packets between networks and manages traffic.
- Switches: Connects devices within a local network, allowing them to communicate.
- Modems: Converts digital data from a computer to analog for transmission over phone lines and vice versa.
- Cables: Physical media like Ethernet cables that connect devices in the network.
Example of a PAN
- Bluetooth-enabled devices like smartphones or tablets connecting to headphones or smartwatches.
Functionality of LAN (Local Area Network)
- Enables multiple computers to connect and communicate within a limited geographical area, such as a home, office, or campus.
- Allows for file sharing, printer access, and application sharing among connected devices.
Comparison of MANs (Metropolitan Area Networks) with LANs and WANs
- MANs cover larger geographical areas than LANs but smaller than WANs, typically serving urban areas or cities.
- Offers high-speed connections to interlink multiple LANs, facilitating broader communication.
- Unlike WANs, which may span across countries or continents, MANs are confined to a city or region, providing faster data transfer rates.
