Some would say that computers are actually very dumb tools that cannot function without a preset guidance module incorporated into its system. This would literally mean that a computer program will not be able to be of any use without actually being “told” what to do. A computer is unable to act or think for itself, unless the appropriate accompanying software used clearly depicts step by step what needs to be done for any particular activity. Therefore, to understand how the programming works, the user will first have to understand the concepts required to make the system work in the first place.
Some of these should ideally include understanding the terms and programs. Among which would be the famous and basic word processor program, where the input of characters typed using the keyboard will execute the formats of the text, correct any mistakes in spelling and grammar and create the output of displays and points that are neatly organized in text form to be readable for the user.
There are also the game programs where the keystrokes or joystick movements are part of the input which constitutes the calculation of speed and distance the animations take on the screen. These calculations have the output of actions and movements of the particular animation on the screen being viewed.
The stock market predictor is another program that has great input capacity and the ability to give information on the current and past
prices of stocks. This is where the programs tries to recognize the trend in the price fluctuation and has the capability of predicting the future probable price of stocks.
