I/O systems are required to communicate with the computer, without an I/O system the end user will not be able to get the desired output or add input. Hardware Drivers are the nexus between the Hardware devices sitting at the physical layer and the OS sitting at the software layer.
Hardware Devices –> Hardware Drivers -> I/O Ops (Software Level)
All the devices be it peripherals, NICs, RAM, or hard disk all the internal and external hardware components are connected to the OS via a hardware driver, the driver sits between the OS and the hardware layer, and drivers are offered by both the first-party and 3rd party vendors.
Be it the MOUSE, KEYBOARD, HEADPHONES, SPEAKERS, RAM SLOTS, NIC, USB, or any other device all of them are connected via drivers all the drivers need to be installed and updated to make the hardware devices work with OS, if the driver is not updated or driver file is corrupted then the hardware will be disconnected immediately and drivers needs to be updated, the hardware of any type needs to have the right driver installed else it will not work.
CPU —> DRIVER / HW —–> Services (I/0) VIA DEVICES
devices are operated, integrated, and manged via the device manager.
The drivers are hardware-specific hence for the keyboard there will be a separate driver and for each hardware there will be a dedicated driver, each hardware component will have its driver which is offered via first-party or third-party vendors. All these drivers need to be updated regularly, if the driver is not maintained and the hardware is old then the respective device and hardware will not work and will need a fix, all the hardware be it internal or external are connected and integrated via driver installation over the OS layer.
I/O | CPU | GPU | GPU2 | MEMORY & H/W DRIVERS
Below is the list of drivers that are installed in the OS.
- human interface output
- Battery
- Camera
- Keyboard
- Mouse
- Printer
- VR
- Touchpads
- MIDI devices
- Audio Interface
- Video Interfaces
- Processors
- USB
- Security Devices
- Storage Devices
- System Devices
- Network Devices
All the Hardware drivers are Tasks executables which will execute the driver-specific tasks and consume the necessary – CPU | DISK | MEMORY | GPU | RESOURCES.
H/W drivers will have the following details: |Driver provides | Driver Date | Driver Version | Digital Signer |
Key Points about H/W Drivers:
- THE DRIVER CAN BE UPDATED VIA LOCAL REPO OR CLOUD REPO ACCESS.
- HE DRIVERS CAN BE ROLLED BACK IF THE CURRENT IMPLEMENTATION FAILS.
- THE DRIVERS CAN BE ENABLED / DISABLED VIA ADMIN ACCESS, THE DRIVERS CAN BE UNINSTALLED AND REINSTALLED.
“THE DRIVER EVENTS CAN BE ACCESSED VIA DRIVER GUI THAT WILL HAVE TIMESTAMPED EVENT TRIGGER DETAILS“
NOTE : Choosing the right driver for hardware is very important as the driver will need to be updated frequently to keep the hardware up and running.
