A keyword is a word or group of words used to search the Internet when using web search sites such as Google, Yahoo!, or Bing!. Regardless if the search term uses a single word, a group of words, or a complete sentence, the entire search phrase is called a keyword.

The careful selection of keywords, in combination with using phrases called “operators,” can greatly improve your search results. Many search engines support ways to specify, limit, or select search options using “Boolean” operators. Don't be afraid of the term Boolean, since Boolean operators include simple words such as AND, OR, and NOT that help give a search site more specific instructions to conduct a search.

Authentication is how someone (often a website) verifies you are who you say you are, also known as your “identity.” The basic idea goes back thousands of years – any time a sentry said, “Halt! Who goes there?” he was taking the first step of authentication. Websites use authentication when you “log in” using your username and password, which is how a website essentially asks the same question “halt, who goes there?” Enter the correct information and you are “authenticated” and can access the website.

A WiFi range extender is a device used to extend the range of an existing WiFi network. WiFi is, of course, the name used for wireless internet connections in most offices and homes. One limitation of WiFi is that its radio signal has a limited range because of WiFi devices' power limitations. You may notice that your WiFi signal doesn't cover your whole house or office or that there are areas where the signal isn't as strong, and your mobile device doesn't have as many signal bars lit up.

Otherwise known as Quick Response codes, a QR code is a graphic image that contains information in the form of black and white squares. QR codes are images shaped like a square with a black and white digital pattern. When scanned, your camera reads the code and uses the information to perform a task, such as open a webpage. QR codes are commonly used in printed material, apps, or webpages to scan the QR code with a smartphone and open a web page or other application.

5G is the next generation (5th generation) of wireless technology for mobile devices like smartphones. 4G LTE (for 4th generation Long Term Evolution) is currently the fastest technology and used in almost all smartphones and cellular networks in the United States and most countries around the world. It might replace the need for WiFi in many locations since 5G can be as fast as WiFi speeds.

A multi-core processor is a single processor chip that has more than one processor on a single chip contained in a single package. A processor sometimes referred to as a "core," is a circuit that performs instructions or calculations. Since a multicore processor has more than one processing unit, it can perform calculations and run programs at faster speeds than a single processor chip. Multicore processors are commonly used in many of the current computers, smartphones, and tablet devices and make our devices run faster than they would with a single-core processor chip.

Bluetooth is a wireless communication standard that connects electronic devices to each other. If you're wondering what those things are that resemble large hearing aids in so many people's ears, those are Bluetooth receivers. The receiver communicates with a cell phone using Bluetooth. In fact, any electronic device with Bluetooth can communicate with another Bluetooth device. Think of it as a wireless cable connection between two pieces of equipment.
