What is 802.11b?

802.11b is one of several Wi-Fi standards developed by the Institute of Electrical and Electronics Engineers (IEEE). It was released in 1999 along with 802.11a as the first update to the initial 802.11 specification, published in 1997. Both 802.11a and 802.11b are wireless transmission standards for local area networks, but 802.11a uses a 5 GHz frequency, while 802.11b operates on a 2.4 GHz band. The 802.11b Wi-Fi standard provides a wireless range of roughly 35 meters indoors and 140 meters outdoors. It supports transfer rates up to 11 Mbps, or 1.375 megabytes per second. ... Read more

What is Networking?

A network consists of multiple devices that communicate with one another. It can be as small as two computers or as large as billions of devices. While a traditional network is comprised of desktop computers, modern networks may include laptops, tablets, smartphones, televisions, gaming consoles, smart appliances, and other electronics. Many types of networks exist, but they fall under two primary categories: LANs and WANs. LAN (Local Area Network) A local area network is limited to a specific area, such as a home, office, or campus. A home network may have a single router that ... Read more

What is a WAN?

Stands for "Wide Area Network." It is similar to a Local Area Network (LAN), but it's a lot bigger. Unlike LANs, WANs are not limited to a single location. Many wide area networks span long distances via telephone lines, fiber optic cables, or satellite links. They can also be composed of smaller LANs that are interconnected. The Internet could be described as the biggest WAN in the world. You could even call the Internet a Super WAN BAM if you wanted ... Read more

What is a Backbone?

Just like the human backbone carries signals to many smaller nerves in the body, a network backbone carries data to smaller lines of transmission. A local backbone refers to the main network lines that connect several local area networks (LANs) together. The result is a wide area network (WAN) linked by a backbone connection. The Internet, which is the ultimate wide area network, relies on a backbone to carry data over long distances. The Internet backbone consists of several ultra-high bandwidth connections that link ...

What is Ethernet?

Ethernet, pronounced "E-thernet" (with a long "e"), is the standard way to connect computers on a network over a wired connection. It provides a simple interface and for connecting multiple devices, such computers, routers, and switches. With a single router and a few Ethernet cables, you can create a LAN, which allows all connected devices to communicate with each other. A standard Ethernet cable is slightly thicker than a phone cable and has an RJ45 connector on each end. Ethernet ports look similar to telephone jacks, but are slightly wider. You can plug or unplug ... Read more
