Which number or set of numbers represents a socket? 1. 01-23-45-67-89-AB 2. 21 3. 192.168.1.1:80 4. 10.1.1.15.
The correct answer and explanation is:
Correct Answer:
3. 192.168.1.1:80
Explanation:
A socket is a combination of an IP address and a port number, which allows devices and applications to communicate over a network. In networking, sockets play a crucial role in enabling processes to send and receive data.
Breaking Down the Options
- 01-23-45-67-89-AB → This is a MAC address, which is used to identify network interfaces on a local network but does not represent a socket.
- 21 → This is just a number and could refer to a port (FTP control port), but by itself, it is not a socket.
- 192.168.1.1:80 → This correctly represents a socket because it includes:
- 192.168.1.1: This is a private IPv4 address used for local networking.
- 80: This is a port number, commonly used for HTTP traffic.
- 10.1.1.15 → This is just an IP address without a port, so it is not a complete socket.
How a Socket Works
A socket is essential for communication between a client and a server. For example, when you open a web browser and type http://192.168.1.1, your computer creates a socket (your_IP:random_port) to communicate with the web server at 192.168.1.1:80.
Visual Representation
I’ll generate an image illustrating how a socket works in networking.
I’ve generated an image illustrating how a socket works in networking. It shows a client communicating with a web server at 192.168.1.1:80, with labeled components such as IP addresses, ports, and data flow. Let me know if you need any modifications!
