Today there are lot of operating systems in the internet but actually they are only based on these main operating systems. What we see on internet is that windows is an OS, Linux is an OS but actually it is not really true. These are true only in simple understanding but when we explore computers more then we see there are lot of types of operating systems available in the market. These are written below...... Batch Operating System Multi-programming OS. Time-sharing or multitasking operating systems Distributed operating System Network operating System Real Time operating System Hard real--time systems Soft real--time systems Batch operating system: These operating system can not interact directly with the computer. Batch processing is a technique in which an Operating System collects the programs and data together in a batch before processing starts.   Multi-programming OS: These type of OS are able to run multiple jobs simultaneously in the memory. For it, memory is considered a...

C: #include<stdio.h> int main(){     printf("Hello World\n");     return 0; }   C++: #include<iostream> using namespace std; int main(){     cout<<"Hello World"<<endl;     return 0; }   Python: print("Hello World\n")   Node JS: console.log("Hello World");   Java Script: document.write("Hello World");   Objective C: #import <Foundation/Foundation.h> int main(int argc, const char* argv[]){      @autoreleasepool{          NSLog(@"Hello World");      }      0; } JAVA: class HelloWorld{     public static void main(String[] args){          System.out.println("Hello World");     } } BASH: echo "Hello World"

A Communication is the process of transferring messages from one point to another. It is a very vital process in a network. When two networks are connected with each others they have to share data to each others so this process of communication system has three basic elements which are as follows - 1. A sender (source), which creates the message to be transmitted. 2. A medium, which carries the message, 3. A receiver (sink), which receives the message. Data communication is the function of transmitting data from one point to another. In this case, the sender and receiver are normally machines, in particular, computer devices (computers, terminals, peripheral devices like printers, plotters, disks, etc), and the transmission medium may be telephone lines, microwave links, satellite links, etc. However, the messages that are transmitted are only in data form, but not in voice conversations form. Hence, the electronic systems, which transfer data from one point to another, are called dat...

Operating System (OS): An Operating system consists of a set of programs which controls, co-ordinates and supervises the activities of the various components of a computer system. Its function is to link between the computer hardware and the user. An operating system is a software or a series of programmes, which performs various types of functions in order to manage and organize file so". Objectives:  There are lot of objectives of an operating system, actually it covers the birth of a perfect operating system. A user is just like a wanting animal they just want everything. But as a developer we are just tying to make our software more & more better as per user requests. These are some main objectives ------ To describe the basic organization of computer systems. To provide a grand tour of the major components of operating systems. Provide more convenient environment for users. Provide maximum utilized performance to users as per hardware existance. Computer Startup: When a c...

  Application Software:   An application software always works under a system software. These softwares are generally a set of one or more programmes, designed to solve a specific problem, or do a specific task e.g. An application software for payroll processing produces pay slips as the major output, and an application software for processing examination results produces mark sheets as the major output along with some other statistical reports.    And also if a person is writing a program to solve his/her personal and particular problems is also comes under the application software. These programs included in an application software package are called application programmes and who made these programs are also known as application programmers. The most commonly known application software are 1. Word Processing Software: A word processing software enables us to make use of a computer system for creating editing, viewing, formatting, storing retrieving and painting ...

Software generally categorized into two types, which are as follows : System Softwares Application Softwares.        System Softwares:      A system software is a set of programs which is designed to control different-different operations and more extend processing capabilities of a computer system. It can perform these functions one or more depending on program requirements on a given task. Supports the development of other application software. Supports the execution of other application software. Handles the effective & efficient use of various hardware resources, such as CPU, memory peripherals etc.  Controls and communicate with the operation of peripheral devices such as printer disk, tape etc.     And system software makes the operation of a computer system more effective and efficient as we can see in its functions. It help the hardware components work together. These programme which are included in a system software p...

Data Types: There are two data types in C programming language - (1)- Primary Data Types  (2)- Secondary Data Types   (1)- Primary Data Types :      Primary data types are those data types which are defined already in the           language. They can be used directly in the program. These data types one of the main important thing in C programming.  There are mainly three types primary data types----- a)- int : For integer values range = -32767 to 32768 b)- float : For float values range = c)- char : For character values range = -127 to 128

 A digital computer is a digital system that performs various computational tasks. The word "Digital" implies that the information in the computer is represented by variables that take a limited number of discrete values. These values are processed internally by components that can maintain a limited number of discrete states. These discrete values are taken by the decimal digits 0 to 9.  The first electronic digital systems was developed at 1940s late, it was primarily only used for some numerical computations.  As we all know a digital computer uses binary number system & it can only understand a binary number. And a binary number has only 2 digits 0 & 1 . Let me tell you one more interesting thing is that a binary digit is called "bit" here. That means if we use 0 it means its a bit, and vise versa.  In a digital computer all information is only represented in group of bits. After using various programming techniques & some algorithms, these grou...

         You must have listened about C programming from many peoples, yes C is a mid level programming language It contains both language features HLL & LLL so it is called mid level language. So today we will talk about some history & uses of this C programming language.     C was developed at AT & T's Bell Laboratories of USA in 1972. It was designed & written by a man Dennis Ritchie & we also call him father modern programming languages. In the late seventies(70s) began to replace the more familiar languages of that time like PL/I, ALGOL, etc. No one pushed C.       Thus without any advertisements C reputation spread & its pool of users grew. Ritchie seems to have been rather surprised that so many programmers preferred C to older languages like FORTRAN or PL/I, or the newer once PASCAL & APL. But that's what happened. Possibly why C seems so popular is because it was reliable, simple & eas...

High Level Languages:      High level languages are abbreviated as HLL, these languages are too much similar to human language. These are more programmer friendly languages easy to code, debug and maintain. Actually they don't interact with the hardware , rather they focuses more on the complex arithmetic operations, optimal program efficiency and easiness in coding.      High level language requires a compilers or an interpreters to translate source code written in high level language to machine language. We can compile the source code written in HLL to multiple languages. Thus they are machine independent language. Advantages of HLL: It provides higher level of abstraction from machine languages. It is machine independent languages. Less error prone, easy to find debug errors. They provides the better programming productivity. Disadvantages of HLL:  Its take additional time to translate its code to machine code. HLL programmer are much slower than...

DARK WEB :       Today we will talk about Dark-Web ,   the Dark-Web is a WWW(World wide web) content that exists on the internet but we need specific software, system configurations or authorized access to see or make changes in this content. Dark-web is just a part of the internet where 90% of internet data is available right now. The Dark-Web contents are not shown by normal search engines like Google , Bing or other search engines.          The dark-web include small peer to peer and friend to friend networks, as well as large, popular networks such as Tor, Freenet etc. operated by public organizations and individuals.  Users of the dark web refer to the regular web as clean net due to its unencrypted nature. The Tor dark web or onion browsing uses the traffic anonymization technique of onion-routing in the network's top-level-domain suffix .onion REAL WORLD:  If we talk about real world scenarios ...

OPERATING SYSTEM :     Today's lot of operating systems have arrived in the marketplace, but some OS gets failed because of their specifications or trends. Let me tell you what is an Operating System in short " an operating system is just a system software which help us to communicate with a machine using graphical or command line interface."     That's means when someone using his/her smartphone or computer or any type of device that's sure this device has an operating system and there is a proper way to use this device. Every Operating system has its own way or type of using it.    An OS is also making a vital role in the device because there are lot of things in a device which depends on the OS like bluetooth-connectivity, wireless-connections, display and many more things.   WORKING PROCESS :   Basically an OS is a system software so it contains all information about the hardware of this device.    Now...
