'''BOOTING:'''
Process that starts up a computer is called booting. It check for proper functioning of all the Hardware (peripheral) devices attached with the system. It searchs for the operating system and, when located, loads it into the main memory (RAM).
=== '''DOS (Disk operating system) Command''' ===
DOS has a relatively small number of commands, and an even smaller number of commonly used ones Moreover, these Commands are generally inflexible because , in contrast to linux and other Ubix — like operating systems, they are designed to accommodate few operating or argument ( I.e.,value that can be passed to the Commands).
Commands are predefine instruction which is used to perform internal and external operation.
A command can be given in capitals or Small letters also. After Typing DOS command we muct press enter key.
=== DOS Today : The Riseand Fall of Disk operating system: ===
DOS has been a significant part of the evolution of the OS. However , its peak has long been over. Here are the reasons why :
'''1. Outdated Technology :'''
DOS lacks the features and functionalities of today's OSes like Windows, macOS, and linux.
'''2. User—Friendly Interfaces :'''
DOS uses text to understand what the user wants to do. Standalone Dos computers cannot run graphics — based applications as efficiently as modern operating systems.
'''3. Lock of Hardware support :'''
DOS struggles with modern Hardware and drives, making everyday use of modern devices and peripherals impractical.
'''4. Limited software Compatibility :'''
Most software applications are for Windows, macOS, or Linux, making running modern applications on DOS Challenging due to compatibility issues.
'''5. Security Concerns :'''
DOS lacks essential security features, making it vulnerable to viruses, malware and cyberattacks. However, companies continue to develop custom system on it.
