What is an LC circuit (electric circuit)?

An LC circuit, also called a resonant circuit, tank circuit, or tuned circuit, is an electric circuit consisting of an inductor, represented by the letter L, and a capacitor, represented by the letter C, connected together. The circuit can act as an electrical resonator, an electrical analogue of a tuning fork, storing energy oscillating at the circuits resonant frequency.

LC circuits are used either for generating signals at a particular frequency, or picking out a signal at a particular frequency from a more complex signal. They are key components in many electronic devices, particularly radio equipment, used in circuits such as oscillators, filters, tuners and frequency mixers.

What does LCD mean?

LCD (liquid crystal display) is the technology used for displays in notebook and other smaller computers. Like light-emitting diode (LED) and gas-plasma technologies, LCDs allow displays to be much thinner than cathode ray tube (CRT) technology.

What is an LED TV?

In almost every case, an LED TV is a television set with an LCD panel that’s illuminated by light-emitting diodes (LEDs), just like most flat-panel PC monitors. LEDs have all but replaced the older cold-cathode fluorescent (CCFL) backlight, and can allow for reduced power consumption, slimmer design and improved image quality, thanks to better contrast and a greater range of displayable colours.

What is Linux (operating system)?

Linux is a Unix-like operating system that was designed to provide personal computer users a free or very low-cost operating system comparable to traditional and usually more expensive Unix systems. Linux has a reputation as a very efficient and fast-performing system. Linux’s’ kernel (the central part of the operating system) was developed by Linus Torvalds at the University of Helsinki in Finland. To complete the operating system, Torvalds and other team members made use of system components developed by members of the Free Software Foundation for the GNU Project.

What is a Local Group Policy Editor?

A tool for editing certain advanced settings within Windows. In versions prior to Vista these settings applied to all users on any single PC, but later versions allow configuration on a per-user basis.  Typical settings include enabling or disabling access to Windows features. The concept extends beyond the local PC to networks of computers running throughout an organisation, allowing such settings to be centrally managed.

What is LPCM?

Linear pulse-code modulation (LPCM) is a specific type of PCM where the quantization levels are linearly uniform. This is in contrast to PCM encodings where quantization levels vary as a function of amplitude (as with the A-law algorithm or the μ-law algorithm).

What is LTE (4G LTE)?

The fourth-generation mobile communication standard is known as 4G. It allows for much faster data-transfer speeds than 3G, and faster than many home broadband services. You’ll need a compatible phone or 4G dongle to take advantage. LTE stands for Long Term Evolution and is a wireless broadband technology that has been widely adopted and has become interchangeable with 4G – they are the same thing.

What is a Lightning connector?

Introduced with the iPhone 5, iPod nano and iPod touch, Lightning is the name given to Apples new smaller connector that replaces the 30-pin port found on earlier models. An adaptor is available to connect to most, but not all, previously compatible accessories. The initial adaptors available from Apple don’t support video output.
