Line Configuration in Computer Networks

1. Point-to-Point Connection

• Direct communication link between two devices
• Simple to establish
• Examples:
  • Computer connected via telephone line
  • Remote control connected to television

2. Multipoint Connection

• Multiple devices share a single link
• Types:
  • Spatially Shared – Multiple devices use the link simultaneously
  • Time Shared (Temporal) – Devices take turns using the link

Transmission Modes in Computer Networks

1. Simplex Mode

• Unidirectional communication → data flows only in one direction.
• Receiver cannot send data back to sender.
• Examples: Keyboard → Monitor, Loudspeaker, TV broadcasting.

Advantages:

• Full bandwidth used for sending data.
• Simple and cost-effective.

Disadvantages:

• No feedback possible.
• Sender does not know if data is received correctly.
