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...

Types of Softwares

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...

Why you should start programming with C?

         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...
