As technology moves forward with its high speed we also need to learn about the technology features to make a value of ourselves in this Hi-tech world .right? Basic to Basic technology features of electronic devices or tools are developing at a fast rate to balance ourselves in the race of the technology to need to understand and learn all the dimensions of technology and features. Mobile phones, laptops, or PC are one of the basic needs in our daily lives. Without them, we can't even think about a day in our lives.

Enter BIOS in the laptop is such a thing that is very helpful in operating laptops and computers.
What is BIOS?
The full form of BIOS is the basic input and output system. It is the basic operating system that helps in booting or refreshing the laptop or PC. BIOS is the feature that is built into the core processor software of a laptop or PC. It is located on the motherboard chip. The chip that contains BIOS on the motherboard is EPROM (Programmed on an erasable and programmable read-only memory ) that is responsible for retaining the data from the laptop or computer when the switch is off and retrieving the same stored data when the switch of the laptop or computer is turned on.
How does BIOS work?
· BIOS manages the data flow between the laptop and the devices that are connected to the laptop. Such as a keyboard, printer, and mouse. It also manages the flow of data in a laptop or computer to operate systems such as video adapters, hard disk drives, etc.
· BIOS runs through a process which is known as ( Power-On Self Test) POST, which determines whether the connected device is functioning correctly or not and whether the attached devices are operating in the proper place or not. If all attachments are allocated and properly functioning then your computer or laptop startup continues as usual and takes you to load the screen in a matter of seconds with the OK confirmation.
· If BIOS detects any problems or errors screen will automatically appear with a series of beep codes sound that indicates that something is wrong with your device.
