Answer / sahim

compiler and interpreter is same thing but a little difference
between both compiler is compile our program at a time but interpreter check our program line by line.

Answer / charulata

1: A compiler generally takes source code and turns it into
instructions that run on the hardware directly.
4: A compiler searches all the errors of a program and
lists them. If the program is error free then it converts
the code of program into machine code and then the program
can be executed by separate commands.
1: An interpreter generally processes the source code
directly or first tokenizes it into a byte-code type form
to interpret that.
2: An interpreter checks the errors of a program statement
by statement. After checking one statement, it converts
that statement into machine code and then executes that
statement. The process continues until the last statement
of program occurs.

Answer / sushant tambad

compiler:translates the entire program.
interpreter:translates the program line by line.
compiler:requires more main memory.
interpretor:requires less memory.
compiler:converts the entire program to machine code,where all the syntax error are removed and executes the machine code.

compiler : execution time is less
interpretor: execution time is more
