Programming:

Programming is simply a way to define specific instructions or commands that are required to solve a given problem or achieve some purpose . It is true that even before computers were introduced into the world, the concept was long obeyed by humans even without knowing it.The idea is to define a sequence of detailed steps required to achieve some result or make a product ;Where every process requires us to:-

• understand the problem itself
• identify what needs to be the result
• define appropriate inputs
• devise suitable processes on the input to get the final result .

To understand it in the most generalized terms , think of it as inputs being your raw materials and processes being a way to convert your raw materials into some useful items , and outputs being the end result of those items ,that are put to a good use. Such a sequence of detailed steps working their way to complete a job is known as an algorithm.

For defining algorithms , different approaches can be used , such as :-

• Flow charts: Graphical representation of the whole number of processes that take place for every process that defines a particular mechanism,where the basic  diagram symbols used are these :



• Pseudocode : Well, pseudo means false. It actually resembles the real code, written in programming languages, but the one which cannot be executed.

• Programming languages: For communicating with computers we need some languages which help us convey our message to the machine or write actual executable programs while following a particular syntax(like Grammatical rules in English language) . (Though, if it does not make any sense ,we will be discussing that later, so you don’t have to worry too much about it.) Examples include:- Java , C, C++, FORTRAN, Python and many more.

Machines are no different either , they are insensible . Unlike humans, they can't learn, adapt , create or produce . In-fact , its our job to give machines a particular algorithm to have it do some work for us. For example there is a simple algorithm presented in flowchart, psueodocode  or structured English for converting a length in inches to centimeters. Now , jumping to the basic ideology of writing any algorithm, we again need to know what the problem actually asks from us.

We need to get an input that is the length in inches:-

Structured English:

• Read length in inches from user
• Convert into cm
• Store the result
• Output the result

Further illustrations define the same algorithm in different forms:

Flow chart :


Psuedocode:

input inches
CM=inches*2.54
output CM

Have a look at our video tutorial for this Chapter:

For the sake of simplicity , today we will not discuss  the context of any programming language.
But we know for sure that any process or system obeys the very sequential and algorithmic approach taken by computers.

Addition :
In the next chapter, we will be discussing what is known as variables, Constants and about primitive eliments.

 The Card is going to Boast a GDDR5X memory which is faster that the GDDR5 memory, contained by most of the current cards but it's still not as innovative and fast as the HBM. Most of us were expecting the new card to have atleast HBM memory, if not HBM2.

On the other hand , the GTX 1080 is going to have 8GB of VRAM as compared to the current top-notch card , the GTX 980ti ,which has 6GB. In addition , the cards power consumption is going to be way lower than expected ! 

Giving a performance equal to the GTX 980 ti or even more than it , the card's Power consumption rate is going to be considerably lower  than 165 watts as rumored !

                                                                                                                               As far as the expected price of the card is concerned, It is going to be somewhere between the 500 to 600 Dollar range . It might be even greater or lower, as the price of the card can only be assumed right now. ( Courtesy : A forum from TomsHardware.com)

To Add in more information, Nvidia is also going release the following range of cards very soon in upcoming months along with the GTX 1080 ;

In conclusion , GTX 1080 is going to rock the stage with it's low power usage, good quality , 16nm architecture and  a good price, however, only flawed by the use of GDDR5X memory instead of HBM.
