Data  image source:  Pixabay Data is a collection of raw facts and figure which is isolated, unrelated and unorganized, but able to organize into useful information. Data can be manipulated to produce output. Data are the raw facts from which we start to get information. Example: 1, Ram, Table etc.  Database  image source: picpedia A database is a collection of related information about a subject organized in a useful manner that provides a base or foundation for procedure, such as retrieving information, drawing conclusion and make decision.  A database is a collection of data of certain place or person or things in such a way that it can be easily access by an application program like DBMS. A database represents some aspect of the real world. Some examples of database are database of student, database of employee etc. all are related to the real world. It is a collection of related data, which has some meaning.  DBMS (Database Management System) A DBM...

The main advantage of DBMS is that it helps to create an environment in which the end users get better access to more and structured data. The data in a database is available to all managers and end users.  2. Data security Easy accessibility creates greater risks of data security. Since the data in a database can be accessed by all the end users and the managers, there occur some security problems. But DBMS overcome this problem by giving different authority to all users.  3. Reduce data redundancy The same data may be duplicated at many times in many places, which is called data redundancy. A DBMS reduces the duplicated data from a database. 4. Minimized data inconsistency When the same data is duplicated and changed are made at one site, and not on other sites, it causes data inconsistency. But DBMS reduces the inconsistency problem by elimination two entries regard...

C- Data type  Data type is an instruction that is used to declare the category or type variable being used in the program. Any variable used in the program must be declared before using it. It determines how much money space it occupies in the storage and how the bit pattern stored is interpreted. the data type can be either predefined or derived. The predefined data types in C are the basic types (int, float and char) and the type void. the derived data types are array, string, structure etc.  1. int data type The int data type is used for integers. Integers are numbers with no decimal point. It requires 2 Bytes of memory space. it can be either signed or unsigned. Derived data types from int are short int and long int.  For example : 24, -90, 1234, 0 etc. 2. float data type This data type is used for numbers that have a decimal point which are commonly called floating-point numbers.  It requires 4 Bytes of memory space. It can also be signed or unsigned. Derived ...

Feaures of C Source: pixabay.com Simple language:  C language is a simple and easy programming language for both learning and programming; therefore most of the computer programming languages follow its syntax and concepts, like C++, Java, C# etc. Portability: One of the reasons of C’s popularity is its portability. We can easily transform a program written I C from one computer to another with few or no change and compile with the appropriate compiler.  Modular programming language:  C language is a modular programming language, which means that we can divide a C program into small modules according to code functionality, which makes the C program easy to understand. Faster and efficient: C is desirable because it is faster and more efficient than other high-level languages. For e.g., a program to increment a variable from o to 15000 takes about 50 seconds in BASIC while it takes 1 second in C. Middle-level programming language:  C language is a middle-level program...

C Language Introduction  Computer needs a set of instructions to process data. A program is a sequence of instruction to perform a particular task. A programming language is a well defined set of rules for specifying a proggram's sequence of instructions. C is a procedural programming language. It was initially developed by Dennis Ritchie between 1969 and 1973. It was mainly developed as a system programming language to write operating system. The main features of C language include low-level access to memory, simple set of keywords, and clean style, these features make C language suitable for system programming like operating system or compiler development. C seems so popular because it is reliable, simple and easy to use. It is also called Middle Level Language .  EXAMPLES:  Java, PHP, JavaScript and many other languages is mainly based on C language. C++ is nearly a superset of C language (There are few programs that may compile in C, but not in C++). Data type in c...

Features of Computer: Speed: A computer is a fast data processing system. The time taken by the computer system to execute any task is very fast. It can process thousands of millions of data within a second. A recent computer has a speed of 300 MHX. This means that it can execute an instruction in about 10 nanoseconds. Accuracy: Although computer works at very high speed, it doesn’t make any mistake in data processing. It is 100% accurate machine. Errors can occur in a computer, but these errors are due to inaccurate data or bugs. That means if we feed the wrong data to a computer then the result produced by a computer is also wrong.  Data Storage:  A computer can store the data and program in its primary and secondary memory. Primary memory helps to store the data temporarily and secondary memory helps to store the data permanently. Data and program for current use are stored in primary memory. Secondary memories can store the large volume of data for a long period of time....

What is computer? The word computer is derived from the Latin word ‘Computare’ which means to calculate. The computer can be defined as an electronic machine that is used for data processing to produce meaningful information. It receives the data process it according to a set of predefined instruction and then gives the correct result to the user. So it can be defined as a data processor. The father of the computer is known as ‘ Charles Babbage ’. We can say the first calculating machine for counting is Abacus. The question “What is computer?” can also be defined by following diagram: Computers have almost changed the world. Computers have become very essential tools in most walks of life. In almost all fields, advancement, defense, commerce, etc. are the core area where the computers are getting utilized. Today communications are being easy by the growth of computer.  The whole human fraternity is becoming highly dependent on the computer technology; no one can imagine life withou...

Computers have almost changed the world. Nowadays the computer has become a part of human life. It helps people in many ways. It can do most of the things that the human mind can do. In this world, the computer plays the vital role. On the basis of its size, it can be categorized into four parts; they are the supercomputer, mainframe computer, minicomputer, and microcomputer. Due to the speed, accuracy, data storage capacity, diligence, versatility, electronic, etc. of the computer, it is widely used. It is a fast data processing system.
