1. BASIC (Beginners All purpose Symbolic Instruction Code) A programming language developed by John Kemeny and Thomas Kurtz in the mid-1960s at Dartmouth College.Originally developed as an interactive timesharing language for mainframes, BASIC was widely used on the first personal computers. Microsoft's BASIC helped make the Altair the first commercial success of an assemble-it-yourself.
2. Aug 03, 2014 BASIC (an acronym for Beginner's All-purpose Symbolic Instruction Code) is a family of general-purpose, high-level programming languages whose design philosophy emphasizes ease of use.

In computing, the instruction register (IR) or current instruction register (CIR) is the part of a CPU's control unit that holds the instruction currently being executed or decoded. In simple processors each instruction to be executed is loaded into the instruction register which holds it while it is decoded, prepared and ultimately executed, which can take several steps.Some of the complicated processors use a pipeline of instruction registers where each stage of the pipeline does part of the decoding, preparation or execution and then passes it to the next stage for its step. Modern processors can even do some of the steps out of order as decoding on several instructions is done in parallel.Decoding the op-code in the instruction register includes determining the instruction, determining where its operands are in memory, retrieving the operands from memory, allocating processor resources to execute the command (in super scalar processors), etc.The output of the IR is available to control circuits which generate the timing signals that control the various processing elements involved in executing the instruction.In the instruction cycle, the instruction is loaded into the instruction register after the processor fetches it from the memory location pointed to by the program counter.

BASIC stands for beginner’s all-purpose symbolic instruction code, and is a computerprogramming language that was invented in 1964 at Dartmouth University by John G Kemeny and Thomas E Kurtz. BASIC has the advantage of English-like commands that are easier to understand and remember than those of most other languages. Even so, the latest versions of BASIC can do just about anything programming languages like C or Pascal can do.

Basic was the first language made available for personal computers (Microsoft started its business selling a version) and in recent years it has returned to importance as VISUAL BASIC, though the latter bears little resemblance to earlier versions.

BASIC programs have a reputation for being very slow, which they certainly were in the early days of personal computing. This sluggishness was mostly due to the fact that in those days, BASIC was an “interpreted” language; that is, every time you ran a BASIC program, you were really running an “interpreter” which executed your program code line by line, converting it on the fly into a form your computer could understand. That conversion process takes time. Now many good BASIC compilers are available. A compiler does the conversion ahead of time and only once, turning the program code into an executable program your system can run directly, at top speed. So modern, compiled BASIC is easier to use and just about as fast as C.

Interpreters do have some advantages, though. The process of writing and testing an interpreted program is actually quicker and more convenient than with a compiled program (for the explanation, see the entry for interpreter). A BASIC interpreter makes especially good sense for creating short, simple programs, which is all that most personal computer users would be willing to tackle. If you’re interested, you can find lots of old computer books full of BASIC programs at public libraries. At any rate, some computers come with a BASIC interpreter. The best example is Microsoft’s BASIC, or GW BASIC, the interpreter that comes with MS-DOS. True IBM-brand PCs had slightly different versions of the interpreter called BASIC and BASICA (Advanced BASIC) that only worked on those computers.
