Hi friends, in today’s article we are going to discuss computer language and operating system. A programming language is a programming language designed to allow an instructor to communicate with a machine, specifically that each programming language on a computer has its own syntax and grammar that are used to write programs.

 There are two types of programming languages ​​that are procedural and non-process. Going to talk about functional language. It is a language that explains the step-by-step achievement of a task and is non-procedural language-focused, regardless of how it is done. , Although the early programming languages ​​were fully procedural and today there are many powerful and user-friendly non-procedural languages. Classification of languages ​​The first machine language, also known as the first generation language, we program in the early years of the computer revolution.

The machine language was a tedious error-prone and machine-dependent, written at the primitive level of binary automatic in machine language. Programs written on one type of machine cannot be executed on a machine code without rewriting all the code on another type of machine. .

 The only language that a computer can understand and implement and therefore programs written in all other programming languages ​​must first be converted or translated into machine language, the second assembly language second generation language before programs can execute. IS, also known as assembly language, emerged as a basic computer application in the early 1950s. Semantics of words uses abbreviations to represent words, although this is machine dependent.

This was an improvement over machine language because it adds or subtracts words used in assembly language instead of zero and machine language. A machine is converted to machine language in a program in assembler and third highest and highest level languages, also known as third generation languages ​​in the mid-1950s, and higher level languages ​​or third generation In the 1970s, English was preferred with new languages, and they were called high-level languages ​​because many lines were seen as code.

 And the machine or languages ​​of the third generation assembly languages ​​could be written using the same instructions and encouraged because of this programming. The process is as independent as Rhea’s machine of third generation languages ​​should be changed to the first machine language execution program languages ​​of the third generation of second languages. Compiler Various popular high-level languages ​​are available. They are basic. It stands for beginners.

 The most common symbolic instruction code that beginners use because it is easy to learn is Fortin which is in formula translation and scientific and engineering applications. Is used Pascal which is named after the French mathematician Blais Pasca L and is used in COBOL, it stands for Common Business-Oriented Language and is used in business applications to see that it There is a very powerful high-level language that is used for various purposes. system software

. Now we are going to talk about the operating system what is the operating system. It is a collection of several programs that make up a computer system used to control an operating system that manages every aspect of a computer system. An operating system manages every aspect of a computer system. Displaying data from running application software on monitoring reports, etc.

Common operating systems include MS-DOS units operating system Novel NetWare and Window, which provide continuous job processing for each event scheduling and operating system process management tasks for the program. Device management if loading. This job job controls the input / output device memory management, deciding which process is primary D In memory, it monitors the amount of available primary memory. It allocates memory to each process.

 This frees memory when the process is complete and final information management. It controls the reading and writing of information in various ways. What are the first operating systems? The type of operating system is a batch processing system. It is a system in which a series of jobs are set up so that programs can be run to accomplish them without manual intervention such as UNIX. Second multi-programming operating system. It is a form of parallel processing system consisting of several at the same time

The programs are run while run on the uniprocessor, for example Windows Unix Linux, performing different tasks simultaneously Execution of orders is not accurate land, the third system of time sharing is directly related with a powerful central computer users, that various user requests. Handled in cyclic format when those different users terminals react to the minesfor example UNIX and Linux and the last is real-time system this is an operating system in which the maximum time from an input stimulus to an output response can be definitely determined for example qnx RT linux VxWorks so friends today we have discussed about computer languages and operating system thank you
