5 Questions
What factors determine the selection of a programming language for writing a program?
The factors include the type of computer hardware and software, the type of program, the expertise and availability of the programmers, the need for specific features, built-in features to support software development, lower development and maintenance costs, stability, scalability, ease of adding new features, portability, and speed of development.
What is Machine Language?
Machine Language is the first generation of programming language, where all the commands and data values are expressed using 0s and 1s, corresponding to the off and on electrical states in a computer.
What is Assembly Language?
Assembly Language is the second generation of programming language, which uses symbolic codes, also known as mnemonic codes, such as ADD for add, CMP for compare, and MUL for multiply, to represent commands and data.
What is the key feature of the third generation of programming languages?
The key feature of the third generation of programming languages is to make the languages more programmer-friendly.
What are the components of an assembly language statement?
An assembly language statement consists of a label, an operation code, and one or more operands. Labels are used to identify and refer instructions in the program.
Study Notes
Factors determining the selection of a programming language
- The selection of a programming language for writing a program depends on various factors, including the type of application, cost, ease of use, and performance requirements.
Machine Language
- Machine Language is a low-level, binary language that is directly understood by the computer's processor.
- It is composed of binary digits (0s and 1s) that the computer's processor executes directly.
Assembly Language
- Assembly Language is a low-level, symbolic representation of Machine Language.
- It uses symbolic codes instead of binary digits, making it easier for programmers to read and write.
- Assembly Language is translated into Machine Language using an Assembler.
Third Generation of Programming Languages
- The key feature of the third generation of programming languages is the use of high-level languages that are easier for humans to read and write.
- Examples of third-generation languages include COBOL, FORTRAN, and C.
Components of an Assembly Language Statement
- An Assembly Language statement consists of four components: label, opcode, operand, and comment.
- The label field provides a name for the statement, the opcode specifies the operation to be performed, the operand specifies the data to be operated on, and the comment field contains explanatory notes.
