Types of operating systems

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...

PROGRAMMING LANGUAGES

Today a programming language is very essential thing in technology market, everything is going to transform in digital world. We handle these digital things with lot of hardware and using programming language. Currently there are lot of programming languages arrived in market like Python, Java, Perl and many more. So today we will talk about what is programming language & how its works? A programming language is the way to talk to a computer machine, generally we can not directly go to the computer and we can not say to the computer to do a specific task, Because a computer only understand the binary data . We need to program it or we can say we need to talk to the computer in computer language to give then computer will understand what we want with them. Generally we talk in different - different languages, so we can also communicate in different - different languages with a computer. Sometimes computer languages goes to complicated for a human being bu...

Man in the middle attack types

Types Of Man-In-The-Middle Attacks : Today internet is one of the most essential thing in our normal life and it plays a vital role in every industries. Our demand of internet is growing day by day and it is not going to stop until now. Man in the middle attack is one of the most common cyber-attack. In this attack an attacker act as a medium between the user and the server when a user send a request to a website for a particular data it can be in any form like login credentials, bank details etc. then server send data to user but when a person is interacting between user & server he/she can see all data. So today i will tell you how an attacker can perform a man in the middle attack ,so just read this blog careful................... 1⃣ IP spoofing: Every device capable of connecting to the web has an online protocol (IP) address, which is analogous to the road address for your home. By spoofing an IP address, an attacker can trick you into thinking you’re intera...

C programming basics - part 1

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

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...
