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 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

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...
