Web scraping is the automated collection of data from websites using an interface designed for human, rather than computer, interaction. It is typically used as a way of extracting unstructured data and importing it into a database for later use. Examples could be reading price or share value information directly from a website or posting queries to an online service and reading the results into an app. Steps are often taken to prevent the scraping of data by machines, so sometimes the most basic approach of copying and pasting by hand as the only solution.

Some low-level configuration tweaks involve manually editing the Registry using the Windows application Regedit.
Also known an ‘inductive charging’, wireless charging uses magnetism to charge a battery without a cabled connection between the charger and the device. It works by creating a magnetic field in a coil located in the charger, which them induces a similar field in a coil in the device and is converted into power. A newer technique called ‘resonance charging’ also uses a pair of coils, but can operate over a distance of a few centimetres rather than requiring physical contact.
A device that can extend the range of your wireless router by receiving and re-transmitting its Wi-Fi signal.
Wireless N150 is a subset of the 802.11n Wi-Fi standard. It incorporates most of the improvements introduced by previous versions, but omits the channel-bonding feature. This limits it to a maximum theoretical data rate of 150Mbps, rather than the 300Mbps available to dual-channel equipment.
