What are the Various compilers of different language?
A program that translates source code into object code. The compiler derives its name from the way it works, looking at the entire piece of source code and collecting and reorganizing the instructions. Thus, a compiler differs from an interpreter, which analyzes and executes each line of source code in succession, without looking at the entire program. The advantage of interpreters is that they can execute a program immediately. Compilers require some time before an executable program emerges. However, programs produced by compilers run much faster than the same programs executed by an interpreter.Every high-level programming language (except strictly interpretive languages) comes with a compiler. In effect, the compiler is the language, because it defines which instructions are acceptable.Because compilers translate source code into object code, which is unique for each type of computer, many compilers are available for the same language. For example, there is a FORTRAN compiler for PCs and another for Apple Macintosh computers. In addition, the compiler industry is quite competitive, so there are actually many compilers for each language on each type of computer. More than a dozen companies develop and sell C compilers for the PC.

The difference between technologies and tools?
Technologies refer to the broad methods, principles, and practices used to create and develop software. A technology is a collection of techniques, frameworks, and concepts that enable software developers to build software systems. Examples of technologies include programming languages, software architectures, operating systems, databases, and web development frameworks. Tools, on the other hand, are specific software applications or programs that are used to support the software development process. Tools are designed to perform specific tasks and automate repetitive or time-consuming tasks. Examples of tools include code editors, debuggers, compilers, version control systems, and testing frameworks.
