Before communication begins, TCP establishes a new connection using a three-way

Question

Before communication begins, TCP establishes a new connection using a three-way handshake. This is because: A. TCP could use a two-way handshake instead, and only introduced the third handshake to prevent the conversation from being intercepted B. TCP establishes a stream of bytes in both directions, and the three-way handshake allows both streams to be established and acknowledged. C. It is considered polite to shake hands three times when first meeting. D. TCP end points maintain state about communications in both directions, and the handshake allows the state to be created and initialized.

Explanation / Answer

Answer:

B. TCP establishes a stream of bytes in both directions, and the three-way handshake allows both streams to be established and acknowledged.

As TCP is Bi-directional protocol so, both ends should be able to send data reliably. Both parties need to establish and acknowledge the connection. Therefore we need threeway handshake.
