OCR J277 2.5 Characteristics and purpose of languages

The mainframe server of a large data center was originally controlled by (a)   .

• Satellite communication

• Large electrical cables

• Wireless signals

• Optical fibers

You are writing a program for a specific processor. Which language would you use if you want your code to be closely mapped to the machine architecture?

• Java

• Assembly

• C

• Python

You are writing a program that needs to execute a specific set of instructions. You know that the CPU can only decode and execute instructions in a certain format. What is this format called?

(a)  

• High-level language

• Assembly language

• Source code

• Machine code

You are developing a software application and you want to make the coding process easier. Which language would you use that has commands similar to English?

• Assembly language

• High-level language

• Source code

• Machine code

Consider a high-level programming language like Python. If you write a single line of code, such as a loop, how many machine code instructions can it translate into?

• Depends on the processor

• No machine code instructions

• Many machine code instructions

• One machine code instruction

A programmer is writing a low-level language program. What does he directly manipulate?

• Memory

• Monitor

• Processor

• Hard drive

You are developing a software application for a client. The client has limited hardware resources and needs the application to run as efficiently as possible. Which type of programming language would potentially be less memory-efficient and slower to execute if not optimized well?

• High-level language

• Machine code

• Source code

• Assembly language

A software developer is writing a program in Python. What does the Python interpreter translate into machine code for the computer to execute?

• Machine code

• Assembly language

• Python language

• Source code

You are writing a program that needs to communicate directly with the computer hardware. Which language would you use to write this program?

• High-level language

• Assembly language

• Source code

• Machine code

You are developing a software application in Python. Which type of language would require a translator, like a compiler or interpreter, to convert your Python code into machine code that the computer can execute?

• High-level language

• Machine code

• Source code

• Assembly language
