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. Optimises code for speed and memory.

• 1. Doesn't produce executable files.

• 1. Code must be recompiled for changes.

• 1. Does not optimise code.

• 1. Errors detected after compilation.

• 1. Compiled code is platform-specific.

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

• 1. Requires significant memory for compilation.

• 1. Produced programs run quickly.

• 1. Translates code one instruction at a time.

• 1. Source code must be distributed.

• 1. Quick error detection during execution.

• 1. Generates executable files.

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

• 1. Needs translation every run.

• 1. Executes instructions immediately.

What does IDE stand for?

Match the following

• 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.

• 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.
