Answer
Array is an indexed list of elements.In Javascript,arrays are implemented in the form of the 'Array'object.The key property of the 'Array' object is length,i.e the numbers of elements in an array.Two of the Array methods are reverse() andsort()
Semantic errors are those errors which occurs during coding the language.When a statement executes and has an effect not intended by the programmer,it is said to be having Semantic error in it.These are hard to detect during normal testing.Oftenly occurs,only in unusual and infrequent circumstances.
Event Handlers is the capturing events and responding them.The system sends events to the program and program responds to them as arrive.Events can include things a user does,like clicking the mouse,or the things that a system itself does,like updating a clock.Programs that can capture and responds to events are called Event-driven programs.Javascript was basically designed for writing such programs.Almost all programs written in Javascript are event-driven programs.

TCP/IP stands for Transmission control protocol and Internet protocol
