In computing, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer.A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to know precise details of the hardware being used.
A driver communicates with the device through the computer bus or communications subsystem to which the hardware connects. When a calling program invokes a routine in the driver, the driver issues commands to the device. Once the device sends data back to the driver, the driver may invoke routines in the original calling program. Drivers are hardware dependent and operating-system-specific. They usually provide the interrupt handling required for any necessary asynchronous time-dependent hardware interface.
When Windows Installation or other Operating system is completed, there is often a problem occurs =
- We could not use the wifi
- Then when used to watch movies sometimes nge-lag or halting
- Contrast that can not be enlightened or dimmed
- Bluethooth that can not be used
For beginners computer technicians do not panic it because we have not done Driver installation. Then what functions of the drivers will be 100persenworking discuss here. Then 100persenworking will also discuss Driver Installation Tips and Tricks.
Installation of drivers function to enable the performance function of laptop hardware because when you do reinstall the os then the driver and the program is lost.
To find out what drivers are missing you can open them in device manager when there is a sign (?) Then the driver is not installed.Important: if the display adapter is still standard it means that the driver is not installed yet no sign (?).
Image above is the display device manager and list of drivers that exist in every operating system.
We will discuss one by one function
Disk drive is a type of hard drive
Display adapter is a Video Contoller for graphical display and for Game play
Mice and other pointing devices for toucpad and mouse
Network controler driver for wifi.
For Installation drivers can use the way below
Using the Pack driver
Open the driver pack
Then choose setting - expert mode, because we can choose what driver we will install
Then select the install at the bottom.
2. Using the Easy Driver Pack
Open its setup file
Then check the driver to install
Then select start-extract and install driver (recomended)
3. Using Online via Devid.info
First go to device manager then select unsticked driver - right click property - select detail tab - then on property - device instance path
Then copy the device code
Go to devid.info then paste and search, you will get the driver recomendation for you to download.
