                                                 Fundamentals of Programming    


The goal of this article is to provide a simplified mental framework for dealing with all programming languages. In my years of studying different languages alongside with mathematics, I found that they share the same structure. These transferable mental structure have speed up my understanding of any new language I encounter.
In the realm of programming, the whole field can be simplified by thinking of two main players, the data type (object of study) and the functions (method). The data are objects upon which we operate our functions to generate another data. The dynamics between the data type and functions allow us to solve complex problems in just a few codes.
In learning any new language, approach it by having, at the back of your mind, the dynamics of the different data types/data structures with all the allowable functions.
Data type: a classification of data that determines how the compiler or interpreter will process the data. It defines the allowable operations on the data, the meaning of the data, and how the data can be stored.
Function: a clustered sequence of operation to perform a well defined action. Different programming languages uses different terminology for functions: methods, sub-routines, procedures. Function introduces a key concept in programming called scope.
Dynamics: the dynamics of data and function is provided by the looping and iteration rules — also referred to as Control Structure. It literally controls the structure of your program. The ‘for’ loop and ‘while’ loop are some example of providing a dynamic to the whole program. These dynamics allow the programming language to solve problems in a faster way. These dynamics provides the ‘DRY’ principle a role in programming.
Programming Paradigms:
The different language paradigms developed over the years are developed due to the developer’s different mind-set of what to emphasize, data or functions. Object-oriented languages are more inclined to think that everything in the universe is an object. The functional language thinks that everything in the universe is function. The essence of functional programming is that programs are a combination of expression. Expression includes concrete values, variables, and also functions. [1] There are other language paradigms which focus mainly on the dynamics.
Always bear in mind that languages come and go but there fundamental structure stays the same. One advice to learn them all,
In learning any new language, approach it by having, at the back of your mind, the dynamics of the different data types/data structures with all the allowable functions.

INTRODUCTION Digital computer concept:- 1. Digital computers are designed to store, process and communicate information in digital form. 2. Digital computer is any of a class of digital devices capable of solving problems by processing information in discrete form. 3. It is used for processing data represented by discrete, localized physica signals, as the presence or electic current. 4.The main three components of digital computer:- >input:- The user gives a set of input data through input devices. >Processing :- The input data is processed with the help of CPU by well defined and finite sequence of step. >Output : - Some data available from the processing step are output to the user. TYPE OF DIGITAL COMPUTER :- 1.Microcomputer/Desktop computer 2.Minicomputer 3.Mainframe computer 4.Supercomputers Microcomputer :- 1.Microcomputer is also called a personal computer or desktop computer. 2.It includes a microprocessor, memory,...

INTRODUCTION OF DBMS

-
What is Database :- The database is a collection of inter-related data which is used to retrieve, insert and delete the data efficiently. It is also used to organize the data in the form of a table, schema, views, and reports, etc. For example: The college Database organizes the data about the admin, staff, students and faculty etc. Using the database, you can easily retrieve, insert, and delete the information. DBMS (Database Management System):- Database management system is a software which is used to manage the database. For example: MySQL, Oracle, etc are a very popular commercial database which is used in different applications.DBMS provides an interface to perform various operations like database creation, storing data in it, updating data, creating a table in the database and a lot more.It provides protection and security to the database. In the case of multiple users, it also maintains data consistency. DBMS allows users the following tasks:- Data Definitio...

Introduction to cache memory

Cache Memory in Computer Organization Cache Memory  is a special very high-speed memory. It is used to speed up and synchronizing with high-speed CPU. Cache memory is costlier than main memory or disk memory but economical than CPU registers. Cache memory is an extremely fast memory type that acts as a buffer between RAM and the CPU. It holds frequently requested data and instructions so that they are immediately available to the CPU when needed. Cache memory is used to reduce the average time to access data from the Main memory. The cache is a smaller and faster memory which stores copies of the data from frequently used main memory locations. There are various different independent caches in a CPU, which stored instruction and data. Levels of memory: Level 1 or Register – It is a type of memory in which data is stored and accepted that are immediately stored in CPU. Most commonly used register is accumulator, Program counter, address register etc. Level 2 or...
