TCP Port 135: The Basics of Network Communication
Have you ever wondered how computers communicate with each other over a network? One key aspect of this communication is the use of ports. In this blog post, we’ll explore the concept of TCP Port 135 and its role in network communication.
What is TCP Port 135?
TCP Port 135 is one of the thousands of ports available for use in the TCP/IP networking protocol suite. TCP/IP, which stands for Transmission Control Protocol/Internet Protocol, is the foundation of communication on the internet and most local area networks (LANs).
Ports are like virtual doors that enable communication between computers. They allow specific applications or services on a computer to receive and send data packets over a network. TCP Port 135, in particular, is associated with the Microsoft Remote Procedure Call (RPC) service.
Understanding Network Communication
To understand the significance of TCP Port 135, let’s take a closer look at network communication. When two computers want to exchange data, they establish a connection that allows them to send and receive information packets.
TCP/IP divides data into packets, which are small units of information. Each packet includes the data being transmitted, source and destination addresses, and other control information. These packets are sent and received through ports.
When a computer sends data, it chooses an available port from a predefined range of well-known ports. On the receiving end, the computer listens for incoming data on a specific port. This is where TCP Port 135 comes into the picture.
The Role of TCP Port 135
TCP Port 135, associated with the RPC service, plays a crucial role in allowing programs on one computer to request services from programs on another computer. RPC is a protocol that enables a program to execute procedures on a remote computer.
By using TCP Port 135, a program can establish a connection with another computer and invoke procedures hosted on that computer. The RPC service facilitates the exchange of data between the requesting program and the remote program by using TCP Port 135 as the door for communication.
Conclusion
In summary, TCP Port 135 is a fundamental component of network communication. It allows computers to establish connections and exchange data using the Microsoft Remote Procedure Call service. Understanding ports and their roles in network communication is essential for anyone interested in computer networking.
Next time you use an application that relies on network communication, take a moment to appreciate the crucial role played by TCP Port 135 and the underlying TCP/IP protocol suite.
