SERVER :
* Every tech guy should know what the f*ck is a Server.Let me figure out it.

Servers always have two types of nodes, 1. Hardware Node and 2. Virtual Node.
Types of servers : 1.Web Server.
2.Database Server.
3.FTP Server.
4.Mail Server.
CLIENT :
*A piece of software or hardware that sends out request and computes the response in a predetermined fashion.
API :
*Application Programming Interface - Allows various programs to communicate /interacts through a known communication method.
HTTP :
-As all knows, Hyper Text Transfer Protocol.

FAQ-"Why did the Admin added these above (Server,HTTP,API,Client),during the PHP blog".
Ans- " PHP will work only if all the above combines.Without a server ,PHP could not even run on your PC.For an instance say Apache Server from Microsoft ."
