8. What is Node.js
• Node.js is a software platform that is used to build
scalable network (especially server-side)
applications.
• Utilizes JavaScript as its scripting language, and
achieves high throughput via non-blocking I/O and a
single-threaded event loop.
• Node.js contains a built-in HTTP server library, making
it possible to run a web server without the use of
external software, such as Apache or Lighttpd.
• Node.js is control.

• cURL is a computer software project providing a library and

protocols. The cURL project produces two products,
libcurl and cURL. It was first released in 1997.
