Batch Process As some computing tasks can be tedious and repetitive. A batch process is used to automate much of the work. A batch process performs a list of commands in sequence. It can be run by a computer’s operating system using a script or batch file, or may be executed within a program using a macro or internal scripting tool. For example, an accountant may create a script to open several financial programs at once, saving him the hassle of opening each program individually. This type of batch process would be executed by the operating system, such as Windows or the Mac OS.
