What are the differences between HTTP 1.0 and HTTP 2.0 protocols in terms of their architecture and performance?

The main differences between HTTP/1.0 and HTTP/2.0 concern architecture and performance:

• Multiplexing:

  • HTTP/1.0 opens a new TCP connection for each request, leading to delays.
  • HTTP/2 supports multiplexing — multiple requests and responses are transmitted simultaneously over a single TCP connection, reducing delays and increasing efficiency.

• Headers:

  • In HTTP/1.0, headers are transmitted in text format, which increases the amount of data transferred.
  • HTTP/2 uses a binary format and header compression (HPACK), which reduces network load.

• Priorities and flow control:

  • HTTP/2 allows setting request priorities and managing data flow, improving resource allocation.

• Server push support:

  • HTTP/2 can proactively send resources to the client (server push), which is not available in HTTP/1.0.

As a result, HTTP/2 provides more efficient network utilization, reduces delays, and improves the performance of web applications compared to HTTP/1.0.
