Computer structure - what are the computer components?

• RGB, HDMI, USB, CPU & RAM
• CPU, RAM, Storage, Input/Output, Network
• Keyboard, Mouse, Screen and a Printer
• CPU, GPU, AI and ML

What is Computational Thinking?

• The way programmers think and write their computational code
• Thinking about a problem in a way that a computer would, while expressing it a way that all machines can understand the problem
• The thought process of formulating a problem and expressing its solution, in such a way that a computer, human or machine can carry it out
• The process of analyzing text in an NLP or NLU engine, which enables computers to understand human text, voice or images

What is O(n) complexity?

• A complexity which is linear to the problem size
• A complexity which is dependent on the problem size
• A complexity which is exponential to the problem size
• A complexity which is fixed, no matter what size the problem is

What is the difference between software and hardware?

• Software can be replaced rapidly while hardware stays constant in the computer
• Software is the code executed by the computer while hardware are the physical components of the computer
• Hardware is not flexible, while software can be stored in soft containers
• Hardware is the computer CPU and storage while software are input and output devices

• The number 1,024

• Exit code for a python function

• Input request in a web page

• The letter B

What is the difference between Binary Code and High Level programming language?

• Binary code in encrypted, while high level programming is not
• High Level Programming is requires compilation or interpretation, while Binary Code doesn't
• High Level programming is just another way to represent Binary Code, there is no real difference
• Binary Code can be executed on every platform, while High Level Programming is tailored to a specific one

Relational Database meaning is

• The relationships between different data columns in different tables
• The relationships between different tables of data
• The ability to relate to different data rows in the database
• The fact that the data has structure, while other databases don't

Software Development Life Cycle includes

• Development and testing
• Analysing, designing and testing
