Certificate Course & Programming Courses
A program is a set of instructions written in a language (such as BASIC) understandable by the computer to perform a particular function on the computer. A well written program could be parceled well to form an application package customized for solving specific type of problem on the computer system. A computer programmer is computer scientist (a professional) skilled in using constructs of programming languages to develop executable and acceptable computer programs. A software developer is a programmer. Programmers often work hand in hand with system analysts on large projects. Programming languages are artificial notational languages created or developed to be used in preparing coded instructions on the computer for later execution by the computer. They are usually composed of series of usage rules (syntax) that determine the meaning (semantics) of expressions written in the language. Each programming language comes handy with its own translator i.e interpreter or compiler as the case may be. Programming Programming is the art of developing computer programs with the aid of selected programming language by a computer programmer. It is a special skill whose quality is tested by the quality of the resulting program or software. In programming, programming stages must be properly followed, i.e from problem definition to maintenance and review
About this Course
Certificate Computer programming Course can be defined as the set of processes involved in designing and developing an executable computer program for accomplishing a specific task through computers. Programming involves tasks such as analysis, algorithm generation, profiling algorithms’ accuracy, and implementing the algorithms in a chosen programming language (commonly referred to as coding).
In other words, programming can be understood as the sequence of instructions that will automate the performance of a task on a computer. In general, the purpose of programming is to solve a given problem. The process of programming thus often requires expertise in several different subjects, including knowledge of the application domain, specialized algorithms, and formal logic.
It is a formal computer language which is designed to communicate instructions or commands or orders to a machine, particularly a computer. Programming languages can be used to create program to control the behaviour of the machine.

Machine Language
A computer or a machine only can understand its machine language which is Defined by its hardware architecture. This directly executed by 8 CPU that is central Processing Unit of the computer. Machine language generally consist of numbers that is 0 and 1. This 0 AND 1 codes are difficult to understand by the programmer.
-
Assembly Languages
It is low level language for computers and microprocessor and other Programmable devices. It is basically English like abbreviations to perform operations. Now we need to convert assembly language to machine language as CPUs do not understand assembly language. So assembler converts the Assembly language to machine language basically an assembler is a translator program which is used to convert the language. Example of assembly languages are : GO, JUMP, RUN, ADDR etc. These are the basically assembly language instructions.

High Level Languages
As a requirement of the developing a fast and easy language for developer to understand, high level language comes in existence. Feature of High Level Language: a) fast programming process. b) instructions are written in almost like everyday English. It takes large amount of time to convert high level language to machine language. So interpreter programs were developed to execute high level language without compiling it. Example : Scripting languages- such as JavaScript and PHP are processed by interpreters.
