Answer 1

Math - provides basic mathematical operations

As one can clearly see, The 'maths' term will deal all the mathematics stuff and henceforth, this class will provide all the mathematical operations.

String- Implements the string type and array related operations

We have different classes to deal with different operation. Similarly, in that way we will need a class that will deal with all the string related operations. So Jack OS provides string for the same purpose.

Array- Implements the array and array related operations

Just like string, for arrays we need array Jack OS classes

Output- handles the text output on screen

The role of output is to give the output on the screen in form of text or anything. So as the name suggests the output class here deals with all the text output on the screen

Screen- not a part of jack OS

Keyboard- Handles users input from keyboard

Keyboard acts as data input device. The users can type anything using the combinations of the keys on keyboard. So, as the name suggests the keyboard is used to handle the input from the users using keyboard.

Memory- handles memory operations

After all the input, out functions, there is a need for storing of different data, there should be some class that keeps record of all the things we have done and that can be obtained through using memory class of Jack OS.

Sys- provides some execution-related services

What our normal systems do? They too provide different services for execution of different types of programs and commands. And so, here also sys provides different execution-related services.

Mouse- not a part

Printer- not a part

Network- not a part

Vector- Handles graphics output on screen

For handling various high or low graphics, there should be a particular class assigned for the same purpose. Simple output doesn't have the ability to handle with various new emerging graphics, so Vectors plays a important role in handling such graphics.
