USB B

HDMI

known as High-Definition Multimedia Interface The High-Definition Multimedia Interface (HDMI) connector is used to connect a computer to an HDMI monitor or TV.

IR

known as Infrared Infrared (IR) communication technology uses light waves to transmit information through the air. The light used by IR devices is just past the visible red light spectrum, so it's invisible to us. The simplest example of an IR device is a TV remote. When you press a button on a TV remote, IR light is emitted from the front of the remote and picked up by an IR receiver on the TV. Infrared is used by some portable devices such as tablets and smartphones.

RJ-45

known as Register-Jack 45 Most computers provide a Registered Jack 45 (RJ-45) connector that allows you to connect the system to a network.

USB

known as Universal Serial Bus Universal Serial Bus (USB) Type A connectors are rectangular in shape. One end is typically plugged directly into the computer, and the other is plugged into a peripheral device.

VGA

known as Video Graphics Array The Video Graphics Array (VGA) connector is used to connect older monitors to a computer. You can identify this connector by its blue color and three rows of pins.

List the 6 troubleshooting tips for external devices

~Check all cables and connectors to make sure they're securely seated. ~ if the device requires a separate power source in order to operate, verify that it's plugged in. ~If you're installing the device on Windows, open Device Manager and make sure the device is listed and enabled. ~Try installing the device on another computer system to make sure the problem doesn't lie with the device itself. ~Update the device driver. ~If you've recently updated the device driver and the device no longer works, roll back the driver to the previous version or revert the operating system to an earlier restore point.

Output is

~Computers use output devices to display or send information.The mostly common type of output device is the monitor. Information is usually displayed on a monitor screen as it's being processed by the computer.

What is the difference between a FireWire and USB connector?

~FireWire functions in much the same manner as USB, allowing you to connect external devices, such as digital cameras, extra hard drives, and scanners to the computer system.Meanwhile USB allows you to connect a variety of external devices, including printers, digital cameras, external hard drives, and smartphones. USB ports and connectors come in four shapes: Type A connectors are rectangular in shape. They are designed for connections that may be plugged and unplugged frequently.

What is an illustration of~Drivers

~For some peripheral devices, you may need to load drivers before connecting the device for the first time. Drivers contain software instructions that the computer needs in order to communicate with the device. For many devices, the necessary drivers are included with the operating system. Other devices may require you to manually install the drivers on the system prior to the first connection. Device drivers may also need to be updated when manufacturers fix bugs and vulnerabilities.

What is an illustration of~Network

~If a computer has access to a local network, either wired or wireless, you might install and configure peripherals to be accessed over the network. For example, you might install an Internet Protocol or IP-based printer and then configure it using a web page in a browser. Another example would be a Wi-Fi access point.

Input is

~Input devices allow you to send data or commands to the computer. There are several types of input devices.

What are the 9 most common peripheral devices?

~Nine most common peripheral devices include computers,speakers,Mobile phones,Mouses,keyboards,earbuds,microphones,webcams ETC.

Which type of connector would you use to connect a keyboard to a desktop?

~The connector "Input".

What are the main functions of computer hardware?

~The main functions of a computer hardware are Input,output,processing and storage.

What does the term hardware refer to ?

~The term hardware refers to the physical components of a computer.

What is an illustration of~USB

~USB devices are hot-swappable. This means you can plug and unplug USB peripherals while the system is running. The system will automatically detect the addition or removal of a device and make the necessary configuration changes. Before disconnecting external storage devices, you need to 'stop' them properly in the operating system before removing them to prevent data corruption. USB devices can be plugged in directly to a USB port on the computer or to an external USB hub that's connected to the computer..

What is an illustration of~Self Powered USB Devices

~USB ports can provide power over the connection. USB devices can receive up to 500 milliamps of power from a USB 2.0 port and up to 900 milliamps of power from a USB 3.0 port. If a device can operate on this much power, it's considered a bus-powered device, which means the USB port provides 100 percent of its power. If a device needs more power than this, it's considered a self-powered device and will typically have an external power adapter that plugs into a wall outlet
