Distributed computing allows collaborative research and computational tasks across systems.

Types of Communication Modes

Simplex Mode: Unidirectional communication; only one device can transmit (e.g., radio stations).
Personal Area Network (PAN): Connects devices within a short range (1-100 meters), utilizing Bluetooth and Zigbee.
Local Area Network (LAN): Commonly used in homes and offices, connects computers within a limited area (up to 2 km) using Ethernet and Wi-Fi.
Campus Area Network (CAN): Connects multiple buildings within a campus (1-5 km) using Ethernet technology.
Metropolitan Area Network (MAN): Connects computers over a city or town, spanning 5-50 km, using technologies like FDDI.
Wide Area Network (WAN): Covers large geographical areas beyond 50 km, including the internet, using leased lines and dial-up technology.

Comparison of Network Types

PAN: Range of 1-100 m, very high transmission speed, very easy maintenance, very low cost.
LAN: Up to 2 km range, high speed, easy maintenance, low cost.
CAN: 1-5 km range, high speed, moderate maintenance, moderate cost.
MAN: 5-50 km range, average speed, difficult maintenance, high cost.
WAN: Over 50 km range, low transmission speed, very difficult maintenance, very high cost.

Network Types Based on Design

Client-Server Network: One or more dedicated servers control the network, with multiple clients connecting for resource sharing.
Peer-to-Peer Network: No central server; each device (peer) connects with others, sharing resources freely without restrictions.

Wired Computer Networks

Utilize physical cables for stable and reliable data transmission, minimizing interference and resulting in high speeds.
