Basic computer lessons and training
After getting involved in repairing and studying computer for a while, I have decided that I should work on creating something that will be easier for novice to learn computer. So, to extend my plans, I will be posting a series of learning materials and tutorials to guide you through the basics of learning computer and I am sure that it will help you a lot in your further studies. So, at the beginning I will be discussing about computer hardware and then some very important software. So, lets begin
WHAT IS COMPUTER?
Computer is nothing but an electronic device which processes data and perform various logical (and, or)and numerical operations (+, -, /, *) under the control of sets of instruction which we call a program. Computer has the capacity to store data for future use. So, a computer basically works on the Input – Process – Output cycle of operation.
Input: Input is nothing but a collection of numbers, letters, images etc which are given to computer for further processing. Some examples of input device includes mouse, keyboard, scanner, joystick etc.
Process: Process is an action taken by computer in the input data based on the instruction given by the user. This is an inner process of computer system and CPU (Central processing Unit) is the main part responsible for this.
Output: Once the data given by input is processed by the CPU or processor, the results are given as output which can be seen on the devices like Monitor and printer.
To understand this lets take an example as a reference. If you want to make an apple Juice, first you take an apple which is input and then you put it in the juicer and this is a process where juice is made. Finally you get a juice which is an output.
So, this is how computer basically works. This is a very general process and the exact way of working is more complex and requires a deep knowledge of Mathematics and Electronics.
