The Correct Answer and Explanation is :
The correct answer is b) Stateless.
Explanation
The Internet Protocol (IP) is a fundamental protocol used for transmitting data across networks. A basic characteristic of IP is that it is a stateless protocol. This means that each packet of data sent over an IP network is treated independently, without the need for a connection to be established or maintained between the sender and receiver. Each packet is routed based on its destination address, and the network does not retain information about the packets that have already been sent or their order.
Being stateless has several implications. Firstly, it allows for greater flexibility and scalability in network design. Since each packet is independent, networks can handle varying amounts of traffic more efficiently. If a packet is lost, it does not affect the transmission of other packets; they can continue to be routed without any dependencies. This characteristic is particularly useful in environments with high traffic or in situations where the path taken by packets may change due to network conditions.
Moreover, statelessness simplifies the implementation of IP. There is no need for the protocol to manage the state of each connection, which reduces the complexity of network devices and contributes to faster processing of data packets. It also aligns with the design of the Internet itself, where different devices and services may be added or removed without disrupting overall communication.
However, this stateless nature also necessitates the use of additional protocols to handle reliability, ordering, and error correction. For instance, the Transmission Control Protocol (TCP) operates on top of IP and adds features like connection-oriented communication and state management to ensure that data is delivered reliably and in the correct sequence. This layered approach allows the flexibility of IP to be combined with the reliability needed for many applications.
