Introduction to Software and Language Processors
The supplied software resource explains computer instructions through familiar examples such as ATM transactions and groups instructions into input, output and storage operations before introducing language levels.
1. Software as instructions
Software can be understood as instructions that tell a computer what to do. A useful learning method is to connect each instruction type with an everyday process such as using an ATM.
2. Input instructions
The source lists keywords such as INPUT, READ, GET, ACCEPT, SCAN. They describe receiving data into the system.
3. Output instructions
Output means showing or presenting a result. The notes list OUTPUT, PRINT, DISPLAY, WRITE, SHOW as common instruction keywords.
4. Storage instructions
A store instruction saves data or results in memory or storage. The source gives purposes such as saving data, storing intermediate results and preserving information.
5. High-level and low-level languages
The supplied resource divides computer languages into high-level and low-level languages. Low-level languages are machine-oriented and machine-dependent; the notes mention memory and registers as part of their orientation.
6. Language processors
Language processors are presented as the mechanism by which human-written code is transformed into instructions the computer can execute. For exam preparation, focus on the purpose: bridging human-readable programming instructions and machine-executable instructions.
