Tunneling Definition The term “tunneling” probably brings to mind images of digging tunnels underground, perhaps for a subway system, or for you more technically-minded, a fiber optic cable connection. In the virtual world of computers world, however, tunneling refers to a protocol in which one protocol is encapsulated within another. Tunneling protocols are often used for establishing various types ..

CISC Definition Stands for “Complex Instruction Set Computing.” This is a type of microprocessor design. The CISC architecture contains a large set of computer instructions that range from very simple to very complex and specialized. Though the design was intended to compute complex instructions in the most efficient way, it was later found that many ..
CDMA Definition Stands for “Code Division Multiple Access.” CDMA is a wireless transmission technology that was developed during World War II by the English allies to avoid having their transmissions jammed. After the war ended, Qualcomm patented the technology and made it commercially available as a digital cellular technology. Now CDMA is a popular communications ..
3G Definition 3G is a collection of third generation cellular data technologies. The first generation (1G) was introduced in 1982, while the second generation of cellular data technologies (2G) became standardized in the early 1990s. 3G technologies were introduced as early as 2001, but did not gain widespread use until 2007. In order to be ..
WiMAX Definition WiMAX is a wireless communications standard designed for creating metropolitan area networks (MANs). It is similar to the Wi-Fi standard, but supports a far greater range of coverage. While a Wi-Fi signal can cover a radius of several hundred feet, a fixed WiMAX station can cover a range of up to 30 miles. Mobile WiMAX ..
4G Definition 4G is a collection of fourth generation cellular data technologies. It succeeds 3G and is also called “IMT-Advanced,” or “International Mobile Telecommunications Advanced.” 4G was made available as early as 2005 in South Korea under the name WiMAX and was rolled out in several European countries over the next few years. It became available in the United ..
Mbps Definition Stands for “Megabits Per Second.” One megabit is equal to one million bits or 1,000 kilobits. While “megabit” sounds similar to “megabyte,” a megabit is roughly one eighth the size of a megabyte (since there are eight bits in a byte). Mbps is used to measure data transfer speeds of high bandwidth connections, such as ..
Kbps Definition Stands for “Kilobits Per Second.” 1 Kbps is equal to 1,000 bits per second. That means a 300 Kbps connection can transfer 300,000 bits in one second. 1,000 Kbps is equal to 1 Mbps. Kbps is primarily used to measure data transfer rates. For example, dial-up modems were rated by their maximum download speeds, such as 14.4, 28.8, and 56 Kbps. ..
Cable Modem Definition A cable modem is a peripheral device used to connect to the Internet. It operates over coax cable TV lines and provides high-speed Internet access. Since cable modems offer an always-on connection and fast data transfer rates, they are considered broadband devices. Dial-up modems, which were popular in the early years of the Internet, offered speeds close to 56 Kbps over analog ..
Surge Protector Definition The surge protector is an important, yet often overlooked part of a computer setup. It allows multiple devices to plugged in to it at one time and protects each connected device from power surges. For example, a home office may have a computer, monitor, printer, cable modem, and powered speakers all plugged into one ..
