computer programing Nadine S. Simms, Contributor Good day students. In todays lesson we will be exploring a new topic, computer programing, which, I must say, accounts for a substantial voice of marks for the technological proficiency theory examination. An excellent encompass of this topic is heavy for passing this exam. PROGRAMMING CONCEPTS Programme vs Programming Language A political program is a sequence of instructions absorb by the computer to solve a specific problem. The program is written (coded) in a programming language, which is a execute of words, symbols and codes that enable the programmer to communicate the solution algorithm to the computer. on that point are many programming languages. Each iodine has its throw vocabulary and set of rules called syntax, which governs how words and symbols are unite to piddle instruction. Four categories of programming language 1. Machine languages 2. assemblage languages 3. High- take aim languages 4. es sential languages Machine language This is the lowest level of programming language. It consists of a mountain chain of superstars (1s) and zeroes (0s) called binary digits. It is the sole(prenominal) language that needs no reading for the computer to generalise it. Assembly language This is another low-level language. However, it uses mnemonics (letter codes to for each one machine language instruction).

A special programmer called an assembly program converts each of the mnemonic codes and translates it into its machine-language equivalent. High-level languages These are languages that closely ensure human language and need to first be born-a! gain to machine language before the computer can back up out the instructions. Natural language These are the languages normally verbalise by humans and comprehensible to humans. However, it is very difficult for computers to determine it, referable to vastness of vocabulary, as the languages vary. Difference between ancestry codes and goal codes Sources codes are programmes written in a ill-tempered programming language which might be...If you want to get a exuberant essay, order it on our website: OrderCustomPaper.com
