What is TCP? and how does it works .

What is TCP?

 The full name of TCP is Transmission Control Protocol.  It is a protocol that guides the proper transfer of data and ensures effective network communication.  Additionally, it instructs computers to send data to each other.  Essentially, TCP facilitates data transactions between applications.

 TCP, which stands for Transmission Control Protocol, is a major player in the Internet protocol suite.  It acts as a bridge between the application and network layers, serving the purpose of reliable delivery of services.  Acting as a connection-oriented protocol for communication, TCP helps exchange messages between different devices on the network.

 TCP operates by fetching data from the application layer.  Next, it divides this data into smaller packets, assigns them unique numbers, and ultimately directs these packets to their destination, ensuring successful delivery to the receiver.

How does TCP work? 

 TCP (Transmission Control Protocol) establishes the connection between applications and the network, facilitating message exchange.  Initially, TCP connects the receiver to the sender through the Internet.  Then it breaks our transmitted data into small packets and sends them to the receiver.

 Once the receiver receives the data packets, they are converted back into simple data.  In this way, TCP not only facilitates data transmission but also controls the data transfer speed.  Furthermore, it ensures packet delivery to the recipient system, maintaining communication effectively.

 Use of TCP –

 TCP (Transmission Control Protocol) works to manage data, ensuring secure transmission between servers and users.  It guarantees data integrity and stability, thereby facilitating smooth data transfer across the network.  It finds applications in World Wide Data Exchange Protocol and assists user login for file access and Internet use.

Features of TCP –

  • TCP, short for Transmission Control Protocol, facilitates sending packets from source to destination or receiver.
  • As a reliable protocol, TCP is an integral part of Internet communications, often referred to as TCP/IP.
  • This protocol ensures reliable end to end communication and maintains data flow control.
  • Working in Client/Server point-to-point mode, TCP provides a full-duplex server, enabling both Sender and Receiver roles.
  • With error-checking, recovery mechanisms and flow control functionalities, TCP stands out as a reliable connection-oriented protocol, ensuring smooth data transmission across the network.

Benefits of TCP –

  • This protocol acts as a connection-oriented protocol, providing guaranteed delivery of data packets.
  • If a data packet is lost throughout the network, it will resend the lost packet.
  • By using a sliding window mechanism, it provides an effective flow control mechanism.
  • This includes Go Back or ARP protocols for efficient error checking.
  • Additionally, it uses error control to identify and correct errors.
  • It is a reliable and trustworthy protocol in networking.

Disadvantages of TCP –

  • TCP/IP wide area networks are specifically designed for small networks with limited resources, which can create challenges.
  • Unlike the TCP/IP suite, it cannot represent any protocol stack.
  • For example, it may not work with Bluetooth connections.
  • Despite being developed years ago, there has been no improvement in transmission control protocols.
