Understanding PC Linking Options
Linking PCs can be achieved through various methods, but it's essential to choose the right type of cable for the desired connection. Here’s a breakdown of the options given:
1. Modem Cable
- Used primarily for connecting a computer to a modem for internet access.
- Not suitable for direct PC-to-PC connections.
2. Null Modem Cable
- Specifically designed for connecting two PCs directly through their serial ports.
- It allows data transmission without a modem by crossing the transmit and receive lines.
- Ideal for tasks like file transfers or direct communication between two computers.
3. Serial Port
- A hardware interface used for serial communication.
- While it can be a part of the connection, it does not constitute a linking method on its own.
4. Parallel Port
- Traditionally used for connecting printers and other peripherals.
- Not commonly used for direct PC-to-PC connections.
Conclusion
The correct answer is option 'B', the null modem cable, as it is specifically designed for direct connections between two PCs, allowing them to communicate with each other effectively. Other options either serve different purposes or do not provide a direct linking mechanism.
