Relationship Between 802.11a and 802.11b The original IEEE designations have been renamed to avoid confusion among consumers. Although their new designations are unofficial, 802.11b is referred to as Wi-Fi 1, while 802.11a is called Wi-Fi 2. This new naming structure, introduced in 2018, currently extends to Wi-Fi 6, which is the official designation for 802.11ax, the fastest and most recent technology. 802.11a and 802.11b were developed at about the same time....
The initial idea that telephony returns to is the POTS (plain old telephone service), technically called the PSTN (public switched telephone network). This system is being fiercely challenged by and to a great extent yielding to Voice over IP (VoIP) technology, which is also commonly referred to as IP Telephony and Internet Telephony. Voice Over IP (VoIP) and Internet Telephony These two terms are used interchangeably in most cases, but technically speaking, they are not quite the same thing....
A file system can be thought of as an index or database containing the physical location of every piece of data on the device. The data is usually organized in folders called directories, which can contain other folders and files. Any place that a computer or other electronic device stores data employs some type of file system. This includes your Windows computer, your Mac, your smartphone, your bank’s ATM—even the computer in your car!...
Netbooks were introduced in 2007 and retailed for around $200 to $400. This low cost made netbooks a popular choice for people who didn’t want the expense and hassle of buying and lugging around laptops, which were more expensive and heavier than they are today. The term netbook was coined by Intel while it was marketing its low-power Centrino Atom processor, used in all first-generation netbooks when they came out in 2007....
VPNs are popular because they provide a way to browse the internet without giving away your identity, location, or data.

Some web series are written and filmed by amateurs and require minimal cost for equipment and special effects....
An internet connection with a larger bandwidth can move a set amount of data (say, a video file) much faster than an internet connection with a lower bandwidth. Bandwidth is typically expressed in bits per second, like 60 Mbps or 60 Mb/s, to explain a data transfer rate of 60 million bits (megabits) every second. Why Bandwidth Is Important to Understand It’s easy to dismiss bandwidth as a technical term that doesn’t really apply to you unless you like to play around with tech products or set up internet hardware....
The “Bluetooth” name is taken from a 10th-century Danish king named Harald Bluetooth, who was said to unite disparate, warring regional factions. Like its namesake, Bluetooth technology brings together a broad range of devices across many different industries through a unifying communication standard.

What Does Data Roaming Mean? Roaming refers to the continued data service you get when you go outside your mobile operator’s coverage area. In other words, you’re roaming when you move away from your covered zone—the area where your wireless carrier provides data services.

Streaming Audio Delivery In the past, if you wanted to listen to music or any other type of audio, you downloaded an audio file in a format such as MP3, WMA, AAC, OGG, or FLAC.

Types of Motherboards Types of motherboards are usually defined in terms of their form factor (shape and size), and the technology that’s included on the board. AT: The original motherboard, used in nearly all computers up until the Pentium 2. These measured 13.8 x 12 inches with 6-pin plugs and sockets for power.

What Does ‘End of Life’ Mean? “End of life” refers to the moment when an application is no longer supported by the company making it. In this case, Microsoft’s end of life for Internet Explorer means continued use of the browser after the EOL date is allowed, but Microsoft won’t support it if something goes wrong. Because new computer viruses, malware, and ransomware attacks are developed daily, users should upgrade to Microsoft Edge since they will lose the regular security updates Microsoft has always provided for IE....
Starting today, iPhone 14 Pro users lost in the wilderness—or just in a park without cellular coverage—can send emergency texts via satellite. To the user, this service is free. But Apple has already sunk upwards of $450 million into it. The tech behind it is neat, but it’s even more interesting that only Apple would make such a huge investment for what is, frankly, quite a niche feature. “I think it’s going to be very useful—their crash detection on the Apple Watch has saved someone’s life already—plus it’s huge peace of mind for people going on hikes to just bring their phone without having to buy a beacon or satellite phone,” Nick Dorrell, outdoors writer and owner of hiking and camping site Hikematic, told Lifewire via email....
