Connectors for audio and video systems once fell into professional and consumer divisions with little overlap between connector styles. Prosumer-class components have blurred the lines and mixed the hardware, increasing the need for adapters to tie mixed systems together. BNC and RCA connectors combine with coaxial cables to deliver video, with enough crossover that BNC-to-RCA adapters are common. Writer Bio

Historically, military technology finds its way into the civilian marketplace over time. Many gadgets used today were once unavailable for purchase, and GPS devices arrived in the consumer market in the same way. Military operations aside, owning a device that uses GPS can be useful. GPS works by providing a set of coordinates that indicate a person or device’s location in relation to its elevation, longitude and latitude on the planet....

A black computer monitor conjures simultaneous feelings of confusion and panic within most computer users, especially if the computer issues the normal sounds of a working machine.

Apple’s iPad tablets are lightweight, portable computing devices, but without data access, they’re dramatically less useful. To connect to Internet sites and to get or send data such as email, your iPad must access the same signals that cell phones or connect on Wi-Fi networks. Having the 3G option for an iPad lets you use a cell phone carrier’s network for your data activities. Writer Bio

In the past you’d need a printer, fax machine, copier and scanner to do the things a single all-in-one printer could do. Aside from actually printing, these multi-functional printers offer a range of other features that give them the title of “all-in-one.” Wireless models don’t even need to be physically connected to your computer to communicate with it.

Squelch controls silence the constant background noise in two-way radio receivers during periods of inactivity. Receivers used for telephony such as citizen band, police and fire, and marine radios often spend much of the time in a listening mode when there is no message traffic. During these periods the only output to their speakers is ambient noise, which the receiver’s automatic gain control may make very loud. Writer Bio

Network Time Protocol (NTP) protocol is used for synchronizing the clocks of multiple computers on a network. When information is sent across a network, there is a small delay before it is received. NTP is a tool used to calculate and compensate for this delay. Writer Bio

From tiny MP3 players to high-powered amplifiers, virtually all audio gear has at least one input or output in the form of standard plugs, jacks and screw terminals. Inputs and outputs work differently; if you mistake one for the other in your audio setup, it won’t produce sound and the mix up may damage the equipment. Although they appear similar, inputs and outputs have different electrical properties worth noting. Writer Bio

When Lenovo purchased IBM’s personal computer division back in 2005, Lenovo didn’t just acquire IBM’s iconic ThinkPad notebooks; Lenovo also obtained the necessary technologies to launch several other categories of notebook computers.

With the exception of few models like the ThinkPad X1 Carbon, every Lenovo laptop has a model name, where the letter represents the series and the number refers to the screen size....

Varying by location and company, each tier lists the maximum download speed in megabits per second. Higher-speed tiers cost more per month, so it pays to figure out how much speed you really need. The difference in speed between 3 and 10 Mbps can be substantial, but for some uses will go unnoticed....
