What is the difference between processor and core processor?
Originally Answered: What is the difference between a core and a processor? A processor can have multiple cores. A core is capable of independently executing a single thread or process while the other cores may be idle or executing a completely different process simultaneously.
What is difference between preprocessor and compiler?
Question1: What is Difference between Preprocessor and Compiler? Answer: Though, the preprocessor is the first to look at the source code file and performs several preprocessing operations before it’s compiled by the compiler. Nevertheless, compiler sets the source code file, say “hello.
How is Ram different from processor?
Processor: RAM stands for Random Access Memory, and is used as a short-term memory storage space. The processor, also known as the CPU, provides the instructions and processing power the computer needs to do its work.
Is processor the brain of computer?
The computer’s central processing unit (CPU) is the portion of a computer that retrieves and executes instructions. The CPU is essentially the brain of a CAD system. It consists of an arithmetic and logic unit (ALU), a control unit, and various registers. The CPU is often simply referred to as the processor.
Is compiler a part of processor?
Compilers are not the only language processor used to transform source programs. An interpreter is computer software that transforms and then executes the indicated operations. The translation process influences the design of computer languages, which leads to a preference of compilation or interpretation.
Why preprocessor is used in C?
The C preprocessor is a macro processor that is used automatically by the C compiler to transform your program before actual compilation. It is called a macro processor because it allows you to define macros, which are brief abbreviations for longer constructs.
What is the difference between a compiler and a preprocessor?
Answer: Though, the preprocessor is the first to look at the source code file and performs several preprocessing operations before it’s compiled by the compiler. Nevertheless, compiler sets the source code file, say “hello.c”, through several phases of translation before jumps into preprocessing.
Why is the preprocessor called a preprocessor?
Because it processes the source code before it is compiled hence it’s called preprocessor. It starts it’s work by deleting the comments, following the #directives including header files on your request, replacing the replacement text for macros and symbolic constants, telling the compiler which block of code to accept or ignore.
What is the difference between a preprocessor directive and a macro?
Is a preprocessor directive and declares a new macro named blah. Macros are the result of a #define statement. Preporcessor: the program that does the preprocessing (file inclusion, macro expansion, conditional compilation).
