Assembly Language or Machine Code ? > 자유게시판

Programmes in assembly may be interpreted line by line or may be translated by an auxiliary programme known as assembler. A86 Assembler-D86 Debugger, A386 Assembler-D386 Debugger, ASM (Arrowsoft Assembler), CHASM, Cross Fire, FASM (Flat Assembler, also produces plain machine code), GAS (GNU Assembler), GASM Gage, GASM Owen, GEMA, GOASM, IASM, JAS, Magic, NASM (Netwide Assembler, also produces plain machine code), NBASM, Visual, WASM (Watcom Assembler), WASM (Wolfware Assembler). Programming in assembly differs little from coding in low level, machine code in numbering base of two (long sequences of zeroes and ones grouped by the number of bits contained in one byte). Pascal, the code that is closest to the hardware is called machine code, or low level code. To word this simply, we may say that assembly language is a human-readable text language, and machine code is a machine-readable binary code. Second, speed: instructions written in machine code execute fast. I personally think that, except as a learning exercise, it is a waste of time to write something in assembly that could be written acceptably fast in a high level language. There was no need to log out, if human operators did not respond in a short time, they were automatically logged out by the Dartmouth Time Sharing System.

It was even regularly taught in North American schools, much as a natural human language. Many non-technical human operators often believed that the commands were part of the Basic language, but in fact they were part of the Dartmouth Time Sharing System itself and were also used when preparing Algol or Fortran programmes via the Dartmouth Time Sharing System terminals. ASP, Active Server Pages: a server side scripting language, invented and developed by Microsoft Corporation. It tries to simulate natural language, without pre-defined mathematical structures. The back acronym referred before became commonly accepted. No acronym for Basic originally existed, as can be verified by reading texts of the 1960's and early 1970's, where the name 'Basic' appears ALWAYS, and the name 'BASIC' appears NEVER. To include one or another Basic dialect in the Read Only Memory of a microcomputer became a common practice for many makers of microcomputers in the second half of the 1970's, all of the 1980's, and the first half of the 1990's. The first dialects of Basic were limited to 64 Kilobytes of programme size.

By the time that QuickBasic 4.0 had been released in late 1987, maybe half a million copies of QuickBasic were already in use world-wide. It was created in the late 1970's by the Learning Research Group of Xerox Parc in Palo Alto, and released in 1981 as part of the Xerox Star Information System. It was the final original dialect of Basic at Dartmouth College, released by John Kemeny and Thomas Kurtz as an ANSI Basic compiler, before they left the college to concentrate on the further development of ANSI Basic in the form of True Basic. John Kemeny and John McGeachie declared in an interview in 1974, that at 04 hours (Official Local Time) of 1st May 1964 they had successfully executed the first interactive Basic programme from terminals of the Dartmouth Time Sharing System. This method of editing was necessary because of the use of teletypes as the terminal units for the Dartmouth Time Sharing System. OMS: a programming language for data banks used from the 1960's to the 1980's. Pascal: named in honour to Blaise Pascal (1623-1662), who in 1642-1647 built some units of the "Pascaline", machine of pinion wheels for adding, what is billiards using numbering base of ten.

Assembly: any language of medium level, specific for a given model of processor, which uses instructions written in a numbering base other than base of two (bases four, six, eight, ten, twelve or sixteen are commonly used, but any numbering base can be used), or in short commands known as mnemonic commands, which are better remembered by humans. As opposed to a page (screen) editor, a line editor can only move the cursor horizontally, but not vertically (much like the COPY CON and similar commands that were later used in DOS and other operating systems of the 1970's and 1980's, or like the EDLIN text editor). 6. How much is the cheapest pool table? All of the sides, or rails, of the table are bound in cushions and no pockets are present. Billiards is played on a table without pockets. Billiards uses tables without pockets with 3 balls while Pool uses tables with 6 pockets and 8 balls. Pockets: Snooker tables also have six pockets, but the pockets are narrower and more challenging to pocket balls into, requiring greater precision. These prices provide value for money with delivery and complementary cues, balls, and more.
