                               Data                                            Memory

                               Storage Devices

                      A computer is like a smart helper that can store lots of things, such as pictures,
                      stories and videos. In this chapter, you will learn how a computer keeps all this

                      information safe. You will explore what data is, how memory helps the computer
                      work and the different devices that store all the important things on a computer.

                            DATA

                      In your daily life, you come across a lot of facts and figures in the form of numbers,
                      images, etc.  These are  called  data. You can  say that  a collection of raw  and
                      unorganised facts is known as data. When you organise the data and provide a

                      specific context, it is called information. For example, if we record the age of all

                      students in a class, that collection represents data. Identifying who is the youngest
                      or the oldest among them is information.

                            MEMORY

                      Just like human memory, computers also have memory to store all the data and

                      instructions for performing various tasks.

                      The data and instructions that are entered into the computer using input devices
                      are stored inside the memory of computer. For example, memory is when you

                      wake up daily and remember your morning habits. Your brain helps you do them
                      without anyone’s help.
