Operating System As A User Interface And As A Resource Manager !!                       Operating System as a User Interface : Computer system consists of software and hardware to solve specific problems.  User, application program, operating system and the hardware  are the components  of the computer systems. Application program used to solve specific program. Student attendance  monitoring is the example of application program.  Operating  system is a subset of the system software. OS interacts directly with the hardware to provide an interface to other system software. System software and hardware exist to support the creation and effective use application software.

What Is Operating System? Knowledge Of Operating System!!! Operating System :  Operating system is a program that controls the execution of application programs.it is an interface between application and hardware . Os provides different types of view . For users,  it is abstract view because it provides features which are important for users.Os is intermediary between user and the computer system. The major design goals of an operating system are: Efficient use of a computer system. User convenience  ability to evolve An Os is software that manages the computer hardware. The hardware must provide appropriate mechanism to ensure the correct operation of the computer system and to prevent user programs from interfacing with the proper operation of the system. Efficiency is the one of the parameter for use of computer system.Os system consumes some resources during its own operation. Recommend Articles For More Information : What Is Operating Sy

C Program For Addition, Subtraction, Multiplication, Division Of Two Numbers!! in c programming we can apply arithmetic operations like addition, subtraction, multiplication, division. Let say we take two values of integer type which applied by user. When we perform division of two integer values then answer will be in integer form. For Ex : if we perform 5/2 than we get answer 2. if we want to get proper answer 2.5 then we need to do explicit conversion which is known as typecasting.

Basic Program Of C Language For Print Hello!! We can practice for C language in turbo c++ application and reliable for practice of C. we will write a basic program of C for print Hello. So, First of all in every  C program we have to write this two sentences.       #include<stdio.h>       #include<conio.h> These are two header files, first is stdio.h it means standard input-output header files which handles your programs printf and scanf statements. second is conio.h it means console input-output header files which handles clrscr() and getch() commands in program. clrscr() : clrscr() is used for clear output screen from previous program output. getch() : getch() is used for get all data we write in program, without getch program can not run.

Function Overloading In C++                                    C++ allows you to specify more than one definition for a function name or an operator in the same scope, which is called function overloading and operator overloading respectively. Function Overloading is compile time polymorphism. Function Overloading is the practice of declaring the same function with different signature. same function name used with different number of parameters and parameters of different type. Overloading of Function with different data types is not allowed. A Function is overloaded when same name is given to the different functions. Two functions with same name is must differ in at least one of the following.                              The data type of parameters  The order of appearance   Number of parameters May You Like To Read This Related Articles: What Is Operating System?

Basic Concepts Of OOPC !!                                 OOPC is a object oriented programming which is contain many concept of class and objects. There are many concept like Inheritances, Polymorphism, Abstraction, Encapsulation etc ...  List Of Concepts :   Class Objects Inheritance Polymorphism Abstraction Encapsulation Message passing Class Class is a blueprint for any functional entity. It defines attributes and methods. a class is a implementation of abstract data type. a class is template that specifies the attributes and behaviour of objects.

Introduction Of C++!!                                C++ is a middle-level programming language developed by Bjarne Stroustrup starting in 1979 at Bell Labs. C++ is regarded as a middle-level language, as it comprises a combination of both high-level and low-level language features C++ is a superset of C, and that virtually any legal C program is a legal C++ program.

Phases Of Compiler In System Programming !!!  Phases of compiler : Lexical analysis Syntax analysis Semantic analysis Intermediate code generation Code optimization Code generation Phases Of Compiler In System Programming!!!! Lexical Analysis  Lexical analysis is the first phase of compiler which is also termed as scanning. Source program is scanned to read the stream of characters and those characters are grouped to form a sequence called lexemes which produces token as output. Token: Token is a sequence of characters that represent lexical unit, which matches with the pattern, such as keywords, operators, identifiers etc. Lexeme: Lexeme is instance of a token i.e., group of characters forming a token. , Pattern: Pattern describes the rule that the lexemes of a token takes. It is the structure that must be matched by strings. Once a token is generated the corresponding entry is made in the symbol table. Recommend Articles For More Information : W

CONCEPT OF DBMS!! CONCEPT OF DBMS : A database management system (DBMS) is system software for creating and managing databases. This DBMS provides users and programmers with a systematic way to create, retrieve, update and manage data. CONCEPT OF DBMS!! Objectives of DBMS This following objectives are used in DBMS 1) A Data availability The data availability is responsible for the cost performance and the query update. Availability functions make the database available to users helps in defining and creating a database and getting the data in and out of a database.
