Study Notes
IP Address
- A static IP address is a fixed address assigned to a device, remaining constant over time.
- It is used for reliable communication and easier network management, simplifying remote access to devices.
Transmission Types
Parallel Half-Duplex Transmission
- Allows data transmission in both directions, but not simultaneously.
- It improves efficiency in medium usage compared to simplex transmission.
Serial Simplex Transmission
- Data flows in one direction only, from the sender to the receiver.
- Commonly used in applications where feedback is not required.
Parallel Full-Duplex Transmission
- Supports simultaneous two-way data transmission.
- Increases overall throughput and reduces communication delays.
Packet Switching
- A method of transmitting data in small packets across a network.
- Involves routers to direct packets from Device A to Device B, optimizing bandwidth usage.
Data Packet Components
-
Three components of a data packet:
- Header
- Payload
- Trailer
-
Structure of a data packet:
- Composed of a header (for routing and control), payload (actual data), and trailer (error-checking information).
Data Packet Header
-
Header components:
- Source address
- Destination address
- Protocol information
Data Packet Payload and Trailer
- Payload: Contains the actual data being transmitted.
- Trailer: Usually includes error-checking information, such as checksums.
Packet Switching Process
- Involves breaking down data into packets that are transmitted via different routes and reassembled at the destination.
- Improves network efficiency and reliability, as packets can take optimal paths.
Network Components
- Router: Device that routes data packets between networks.
- Static IP Address: Identifies a device consistently on a network.
- Network Interface Card (NIC): Hardware that connects a device to a network, with a unique manufacturer-assigned address.
Methods of Data Transmission
- Differentiate between serial simplex, parallel simplex, parallel half-duplex, and serial duplex.
- Each has its specific applications and advantages, suited to varying communication needs.

Description
This quiz explores the concept of static IP addresses, which are fixed addresses assigned to a device in a network. Unlike dynamic IP addresses, static IPs do not change and provide consistency, making them essential for certain applications such as hosting servers and remote access. Test your knowledge on their significance and functionality.
