What happens in the Process of Booting ?
When you start the computer, the process known as “booting” takes place. This process occurs whenever we switch on the power or when the machine restarts. The system’s Basic Input/Output System (BIOS) is responsible for activating peripheral devices. In addition to this, it is necessary for the boot device to load the operating system into the main memory.
Boot Devices
via the use of hardware (by pushing the start button) or via the use of software instructions, the process of may be accomplished. Therefore, the term “boot device” refers to a device that loads the operating system. In addition to that, it includes the files and instructions that are necessary to start the computer. For instance, there is the hard drive, the floppy disk drive, the CD drive, and so on. The hard drive is the one that receives the most use.
Introduction Of Booting
The process of switching on the computer is referred to as the computer. The word comes from the phrase “picking somebody by y by the sports “is simple: when the user switches on the computer, they get ready to proceed. It is also called to startup the computer. They are of two types:
- Cold Booting
- Warm Booting
1. Cold Booting :
When the PC is switched on, it loads the booalbe Dos program from disk to memory. This type of computer booting is slow. It can be done only from the on-off switch button on a cabin PC, and so cold switch booting.
3. Warm Booting :
It is also cold and warm. It is faster than cold booting if computers hang for some reason. It may be necessary to reset it by processing the reset button for the cabinats or by processing CTRL+ALT+DELETE then the keys from the computer restart, and the type of reset button is called Cold Hot Booting.
Steps Of Booting :
- The Startup : The first phase involves turning on the power. It provides energy to power the primary components, such as the CPU and the BIOS.
2. BIOS: Power On Self Test : The first phase involves turning on the power. It provides energy to power the primary components, such as the CPU and the BIOS.
3. Loading of OS : The primary computer loads the operating system into its main memory at this stage. At this point, the operating system begins its operations and carries out all of the basic files and instructions.
4. System Configuration : At this stage of the process, the main memory loads the drivers. Programs known as drivers assist in the operation of peripheral devices.
5. Loading System Utilities :The term “system utilities” refers to applications that, among other things, manage the volume, provide antiviral protection, and so on. This phase involves loading the system utilities into the computer’s memory.
6. User Authentication : Once the user establishes a password in the computer system, the system is responsible for verifying their identity. At long last, the system will begin operating after the user has successfully entered their login ID and password.
