Tech Terms: WiFi Networking

Wi-Fi is the name of a popular wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections. A common misconception is that the term Wi-Fi is short for “wireless fidelity,” however this is not the case. Wi-Fi is simply a trademarked phrase that means IEEE 802.11x.

How Wi-Fi Networks Works
Wi-Fi networks have no physical wired connection between sender and receiver by using radio frequency (RF) technology — a frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space.

The cornerstone of any wireless network is an access point (AP). The primary job of an access point is to broadcast a wireless signal that computers can detect and “tune” into. In order to connect to an access point and join a wireless network, computers and devices must be equipped with wireless network adapters.

The Wi-Fi Alliance
The Wi-Fi Alliance, the organization that owns the Wi-Fi registered trademark term specifically defines Wi-Fi as any “wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers’ (IEEE) 802.11 standards.”

Initially, Wi-Fi was used in place of only the 2.4GHz 802.11b standard, however the Wi-Fi Alliance has expanded the generic use of the Wi-Fi term to include any type of network or WLAN product based on any of the 802.11 standards, including 802.11b, 802.11a, dual-band and so on, in an attempt to stop confusion about wireless

LAN interoperability.
Wi-Fi Support in Applications and Devices
Wi-Fi is supported by many applications and devices including video game consoles, home networks, PDAs, mobile phones, major operating systems, and other types of consumer electronics. Any products that are tested and approved as “Wi-Fi Certified” (a registered trademark) by the Wi-Fi Alliance are certified as interoperable with each other, even if they are from different manufacturers. For example, a user with a Wi-Fi Certified product can use any brand of access point with any other brand of client hardware that also is also “Wi-Fi Certified”.

Products that pass this certification are required to carry an identifying seal on their packaging that states “Wi-Fi Certified” and indicates the radio frequency band used (2.5GHz for 802.11b, 802.11g, or 802.11n, and 5GHz for 802.11a).

Tips & Tricks: Read and Send Messages Android

Google Assistant doesn’t just send messages with ease, it can also read messages with equal ease. All you have to do is say something along the lines of “read the text messages for today”. What’s more, you can even use the same conversation to reply to one of them.

Tech Terms: Direct Message

In computer and Internet phrases there are multiple definitions for the DM abbreviation, including the following:

Some also use cool colors to describe more neutral white and greys.

Tips & Tricks: Android Camera and Telescopes

It’s a simple, but useful little trick that people may not know. Just stick your phone’s lens right up to the telescope and you’ll be able to capture the magnified image on the other side. The above photo was taken by my phone through a telescope during my honeymoon in Costa Rica. I think there was supposed to be a bird or something, but it was a jerk and flew away before I took the shot. Works with binoculars, too!

Tech Terms: Proxy Server

A proxy server is a server that sits between a client application, such as a Web browser, and a real server. It intercepts all requests to the real server to see if it can fulfill the requests itself. If not, it forwards the request to the real server.

Purpose of a Proxy Server
Proxy servers have two main purposes: to improve performance and to filter requests.

Improve Performance
Proxy servers can dramatically improve performance for groups of users. This is because it saves the results of all requests for a certain amount of time. Consider the case where both user X and user Y access the World Wide Web through a proxy server. First user X requests a certain Web page, which we’ll call Page 1. Sometime later, user Y requests the same page.

Instead of forwarding the request to the Web server where Page 1 resides, which can be a time-consuming operation, the proxy server simply returns the Page 1 that it already fetched for user X. Since the proxy server is often on the same network as the user, this is a much faster operation. Real proxy servers support hundreds or thousands of users.
