Which of the following are some of the weaknesses of the Linus operation system?

• a non-open source OS, hard to use, and really poor interface

• free, easy to use, better software updates than most other operating systems

• Hard to troubleshoot, open-source system, which means it is weak against security threats

• easy-to-use interface, free and open-source, unsupported hardware

• calculators

Distinguish between programming and computational thinking.

• Computational thinking helps the user write better algorithms, whereas programming helps the user design better computers.

• Computational thinking tells a computer what to accomplish, whereas programming allows the user to work out what to instruct the computer to accomplish.

• Programming tells a computer what to accomplish, whereas computational thinking allows the user to work out what to instruct the computer to accomplish.

• Programming tells a computer what to accomplish, whereas computational thinking allows the user to write in a programming language.
