Which are the main functions of an operating system?
An operating system has three main functions: (1) manage the computer's resources, such as the central processing unit, memory, disk drives, and printers, (2) establish a user interface, and (3) execute and provide services for applications software.

Write a brief story of the operating systems
The first operating system was introduced in the early 1950's, it was called GMOS and was created by General Motors for IBM's machine the 701. Operating systems in the 1950's were called single-stream batch processing systems because the data was submitted in groups.

Which is the difference between Multiprocessing,, Multitasking and Multi threading
Multiprogramming – A computer running more than one program at a time (like running Excel and Firefox simultaneously).Multiprocessing – A computer using more than one CPU at a time. Multitasking – Tasks sharing a common resource (like 1 CPU).
What is a CPU?
A central processing unit, also called a central processor, main processor or just processor, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output operations specified by the instructions in the program.

Exit Ticket: Why is important to have an operating system in your computer? Explain
In simple words you need it for your computer to work because if you dont have it we could say that your computer doesnt work
