GCSE - IDE and Translators

Any program written in a ​ (a)   language (such as Python or Java) is known as ​ (b)   . However, computers cannot understand this. Before it can be run, ​ (c)   must first be translated into a form which a computer understands - this form is called object code.

A ​ (d)   is a program that converts source code into object code. Generally, there are three types:

• * ​ (e)  

• * interpreters

• * assemblers

• high-level
• source code
• translator
• compilers

​ (a)   programming languages are user-friendly, abstracting complex hardware details to boost developer productivity and software portability. However, their abstraction leads to slower execution and less hardware control.

​ (b)   languages, in contrast, provide fast performance and ​ (c)   , ideal for ​ (d)   . Yet, they demand more expertise, carry a higher risk of ​ (e)   , and are less portable, requiring a thorough understanding of the underlying system architecture.

• High-level
• Low-level
• deep hardware control
• system-critical applications
• bugs

Organise these options into the right categories

Groups:

(a) Compilers

,

(b) Interpreters

• 1. Source code must be distributed.

• 1. Needs translation every run.

• 1. Translates all source code to object code at once.

• 1. Does not optimise code.

• 1. Optimises code for speed and memory.

• 1. Quick error detection during execution.

• 1. Translates code one instruction at a time.

• 1. Requires significant memory for compilation.

• 1. Doesn't produce executable files.

• 1. Errors detected after compilation.

• 1. Generates executable files.

• 1. Produced programs run quickly.

• 1. Code must be recompiled for changes.

• 1. Executes instructions immediately.

• 1. Compiled code is platform-specific.

• 1. Runs slower due to on-the-fly translation.

What does IDE stand for?

Match the following

• Runtime Environments

• 1. Tools that assist in the identification and resolution of programming errors by allowing the examination of variable values and program conditions at specific points during execution, and highlighting syntax errors or the exact locations of errors in the code.

• Debugging Tools

• 1. Software that provides a space for programmers to write and edit code, often equipped with features like automatic line numbering, colour coding, and auto-suggestions, but not typically designed to identify errors.

• Editors

• 1. Special software that allows programs to run on computers for which they weren't specifically designed, creating a virtual machine to emulate different computer systems, facilitating the development of programs across different platforms.
