'We need compiler' because computers cannot understand coherent human language, and humans cannot understand coherent computer language. Compilers are like translators that convert human-readable/writable code into assembly code, which is very difficult to understand and use. The compiler then converts the assembly code into binary, which is what an EXE file is.

A compiler is a program that translates your human-readable code into something that the machine understands. Even assembly language is compiled. It is incorrect to say that a human can't understand binary -- the earliest computers were literally programmed by flipping a row of switches on the outside of the box. Its just that modern code is so huge! "On" correlates to a binary one, "off" correlates to a binary zero. Binary code is just our human way of making a distinction between current being on or current being off in an electrical circuit.
If you'd like to see what machine code looks like, download a hex editor (XVI32 is a good one, and freeware at that) and then open up any.exe file in it. You will see the hexadecimal equivalent of the code, plus a text version, if it translates into ASCII. And if you want to know what hexadecimal is, well that's another question....

A compiler is a program that takes source code and translates it to machine code so the computer knows what to do with it. Computers only know ones and zeros, so a compiler helps the computer understands what you want it to do.

Because the processors (CPUs) cannot read the source code that people can read. Processors can only read binary, strings of ones and zeros. Each processor design has a very specific instruction set, and those instructions do simple things like "fetch a byte from disk address 110011001100 and store it at memory address 111000" A compiler converts the program you can read into one that the processor can understand.

programming languages are meant to be read by humans, and in their original source form are meaningless to the hardware. A compiler translates the program into loadable machine instructions and data areas. Those can be loaded on the computer and executed.

can you write in binary form, no.
so a compiler is used to translate your source code into object code so that the computer can understand

to make machine code from high level language. Think of it as a complex language translator.

Because Run-Time Interpreters are too slow (as seen in BASIC).

In order to get things in its proper place. When time comes that we need something, we easily get it. To be organize.
