The programmer converts the desired sequence of steps into specific detail that will enable the computer to perform the tasks required. This needs to be written in a program language that the computer can understand. It can sometimes be tedious and lonely work. Once it is written and documented, the programmer must then test and debug the program to make sure it operates smoothly. Systems programming refers to the type of processes which direct the computer to perform its basic functions.
Applications programming is where most programmers find work.
These are the programs that will be used by the end user or clients. Maintenance and modification work is always in demand. Programming is the area in which many IT and computer professionals find their first jobs. Operations Managers keep the machinery up and running. They control the operation of all computers and peripheral equipment.
