It is used for communication between clients and servers, and is the foundation of the World Wide Web. When a client (such as a web browser) sends a request to a server, the server sends back a response, which can include HTML, CSS, JavaScript, and other types of files that make up a web page. HTTP is a stateless protocol, which means that each request and response is independent of any previous requests or responses. Historical HTTP has undergone several versions since it was first introduced in 1991. Here is a brief overview of the main versions of HTTP: ·          HTTP/0.9: This was the first version of HTTP, released in 1991.

  Differents types of trying table algorithm 1. Linear Search : This is the simplest and most straightforward search algorithm. It sequentially checks each element of the array for the target value until a match is found. 2. Binary Search : This algorithm is more efficient than linear search as it reduces the number of comparisons needed to find the target value. It works by repeatedly dividing the array in half and comparing the target value to the middle element. 3. Interpolation Search : This algorithm is used when the elements - Algorithm linear Search of trying table : Linear search is a method for searching a data structure for a particular value. It sequentially checks each element of the data structure until a match is found or the whole data structure has been searched. Algorithm: 1. Start at the beginning of the data structure. 2. Compare the value at the current position with the value being searched for. 3. If the values match, return the position of ...
