Drivers for USB input devices recognize the signals for the system. This category also includes a touch screen, which is used to communicate with the PC and uses the touch of your fingers. By the method of the cursor control tools are divided into direct, engaged directly in the input cursor visibility, and indirect, by entering the no cursor. Looking in device manager - the audio devices all say working OK. But on bar at bottem of screen get speaker with red cross - Playing audio - Audio trouble shouter cannot find any problems. Sound settings say - No output or Input devices found. Have tried to re-install Realtek audio drivers for motherboard - installed but no change.

More commonly known as a driver, a device driver or hardware driver is a group of files that enable one or more hardware devices to communicate with the computer's operating system. Without drivers, the computer would not be able to send and receive data correctly to hardware devices, such as a printer.

What devices need drivers?

Hardware devices that are unknown by the operating system or that have features that are unknown by the operating system all require drivers. Below is a list of hardware devices and peripherals that require drivers.

What devices may not need drivers

Today's operating systems have a lot of generic drivers that allow hardware to work at a basic level without needing drivers or software. However, if that device has features unknown to the operating system, it will not work without drivers. For example, you could plug any keyboard into a computer and expect it to work. However, if that keyboard has any special keys or features, they will not work until the drivers are installed.

Note

The operating systems generic driver may not be updated as often as the drivers from a hardware manufacturer or computer manufacturer.

What happens if a driver is not installed?

If the appropriate driver is not installed, the device may not function properly, if at all. With some devices, the device may work, but all of its features may not work. For example, a computer mouse usually works without drivers, but if it has more buttons than the traditional mouse, those extra buttons will not work until the drivers are installed.

For Microsoft Windows users, missing drivers may cause a driver conflict or an error that is shown in the Device Manager. If problems or conflicts are encountered with drivers, the computer manufacturer or hardware manufacturer releases a driver update to fix the problems. If updated drivers are available, those drivers need to be installed to replace the existing driver code.

Can a driver make my computer do more?

Installing a driver only makes the hardware installed in the computer function properly. If the correct driver is not installed, installing the latest driver for the hardware can take full advantage of the device. However, you cannot install a driver for hardware not installed in the computer and expect it to make your computer faster or more capable. In other words, installing video card drivers for a video card that's not installed in the computer does not give your computer all the capabilities of that video card. In this example, you'd need the video card hardware and the video card drivers to be installed.

Computers can be used to control a range of devices through the use of sensors. Some of these devices include:
#
Understand how computers can control devices automatically.
Know why computers are more effective at controlling devices than people.
Be able to discuss different examples of devices that can be controlled by computers.
  • Security Lights
  • Burglar Alarms
  • Central Heating Controllers
  • Computer Controlled Greenhouses
  • Automatic Cookers
  • Automatic Washing Machines
  • Microwave Ovens
The role of the sensor
In section 7.3 we looked at how sensors could be used alongside computers to measure quantities (like temperature, light intensity etc) and then log changes in these quantities.
Sensors can also be used alongside computers to control different devices . The process goes like this:

Temperature/Heat - Detect changes in temperature.
Light Sensor - Used to detect the brightness of light.
Humidity Sensor - Detect water in air.
Infra-red Sensor - Detect movement (Used in burglar alarms).
Load/Weight Sensor - Detect weight (Used in digital scales).
Proximity Sensor - Detect how near/far something is.
REMEMBER!
Most sensors are Analogue so we can only connect them to a computer using an Analogue to Digital Converter.
Sensor detects data in the environment around it
Data passed to a computer (microprocessor) inside the device which analyses it and decides what action to take. The computer sends instructions to the device telling it what to do.
The device would carry out the instructions.

Picture Example:
Advantages of using a computer to control devices rather than people
Computers have certain advantages over people when it comes to controlling devices. For example:
Radioactive sites can be too dangerous
for people to work in.
If a computer is monitoring and controlling applications, you do not need to employ people.
Computers can control applications all day, every day without getting tired or bored.
Computers can work inconditions that would be too dangerous for people. Examples include chemical plants, radioactive sites and extremely cold areas (antarctic).
Computers will respond to inputs from sensors accurately every time. E.g. a heater will be switched on as soon as the temperature falls below 10°C.
Computers will respond to data received from sensors very quickly. E.g. as soon as an infrared sensor detects an intruder the alarm will sound.
Examples of Devices that are controlled by a Computer
Key Words:
Security Light, Alarm System, Automatic Heating System, Automatic Greenhouse.
The following examples discuss a number of devices that can be controlled by a computer:
#
Security lights use infra-red sensors to detect movement.
Security lights with built-in infra-red sensor

Video of Infra-Red Security Light
#
Movement is detected when something (man or beast) breaks the infra-red beam. When this happens, the system will turn on the light.
#
If nothing else breaks the beam after a period of time, the system will turn the light off.
#
Burglar alarms work in almost the same way as a security light system.
Input -
Infra-red sensor detects movement when the sensor is broken and this information is sent to the computer
Computer makes the decision to sound the alarm
Alarm is activated.

Modern central heating systems can be programmed to maintain a constant desirable temperature.
Let's imagine our perfect room temperature was set at 25°C - we could use sensors and a computer to:
  • Maintain the optimum temperature of 25°C
  • Turn heating off when it rises above 25°C
  • Turn heating on when it falls below 25°C
#
Here is how it would work:
Heat sensor detects the current temperature and sends this data to the computer built into the heating system
Computer would check the sensor heat data against the temperature setting stored in it's memory. Computer decides if the heating needs to be turned on (or off)
Heating is switched on or off.

Automatic greenhouses can provide the optimum conditions for growing plants by using computer control.
Computers can be used to monitor conditions and control a range of applications (devices) to keep the perfect conditions constant.
Computer controlled greenhouses automatically
detect humidity levels
and switch sprinklers on when
the soil becomes too dry
  • Light sensor
  • Moisture sensor
  • Heat sensor
Control applications (devices) needed:
  • Motor to turn sprinkler on if plants need water
  • Heater to warm the greenhouse
  • Motor to open window vent to cool greenhouse down if it gets too hot.
How the system works:
Computer reads data from sensors and compares it to preset values.
If it is too hot = heater turned off and vent opened.
If it is too cold = heater switched on and vent is closed.
If there is enough light = grow light switched off.
If it is too dark = grow light switched on.
Wet soil = sprinkler switched off.
Dry soil = sprinkler switched on.
NOTE!
The process will repeat constantly. Sensors continually feed new data into the system and the computer will make decisions based on that data.
