ASSIGNMENT no.1

A. What is Computer System?
* Computer is a machine that can perform mathematical and logical operations based on a given sets of instructions to produce a meaningful and useful output. But not only computer, also any software and peripheral devices that are necessary to make the computer function. For example, every computer system requires an operating system.
B. Computer Hardwares:
*Monitor
*Keyboard
*CPU(Central Processing Unit)
*Mouse
*Printer
*Scanner
*Plotter
*Modem
*Speaker
*Microphone
*Light Pen
*Video Camera
*RAM(Random Access Memory)
*etc...

*Non-linear Data Structure*

*A tree is just one example of a nonlinear data structure. Two other examples are multidimensional arrays and graphs. In the next few lessons, we will examine these data structures to see how they are represented using the computer's linear memory. Remember that in the last lesson we saw that we could create a logical representation of a circular queue. Although the actual memory locations were just an array (a group of linear memory cells), we made them seem to be circular by wrapping our pointers around to the front of the array each time they reached the end. This example demonstrated that there are two ways of representing our data structure. The logical representation was a circle or a loop, while the physical representation was a simple linear array.

4.) The smell is bad.
5.) The color of the egg yolk is yellowish-orange.
6.) The shape is oval.
7.) The outer layer is hard.
8.) The inner part is liquid.
