1. Tools: high level languages, machine code, variables, constants, data types

   • High level languagesA high level language is a programming language that allows code to be written. It is similar to a natural human language, such as Welsh or English. Some programmers prefer to use high level programming languages as they are easier to understand, learn and program. Their commands are similar to natural languages like English or Welsh and identifiers can be long and meaningful. High level programming languages also allow the use of powerful commands that perform quite complex tasks such as MsgBox in Visual Basic or the SORT clause in COBOL. High level languages are used when the execution speed is not critical, e.g. in common productivity applications, such as a word processor. Examples of common high level programming languages include: • Basic • Java • Pascal • COBOL • C# • C++
