Know Operating Systems (Briefly)

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...

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...

Programing Langauges HLL vs LLL

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...
