Frequency hopping is a mechanism that is used to reduce interference in wireless communication systems. It works by rapidly changing (or hopping) the frequency of the signal used for communication between two or more devices. The frequency that each device uses is predetermined based on an agreed–upon sequence of frequencies. This technique helps to spread out the transmitted signal power over the available range of frequencies, thus making it difficult for any single receiver to detect the transmission. Frequency hopping can also be used in other types of radio transmissions, such as those used in Bluetooth and Wi–Fi networks.

Web filtering is a process that involves the use of software or hardware to control or restrict access to computer networks and/or websites which contain content deemed inappropriate, dangerous, or otherwise not conducive to corporate policy. It is commonly used by businesses to prevent employees from accessing certain websites while on company networks, as well as in schools and public libraries to protect children from potentially harmful material.

A blade server is a thin, modular computer server with a modular design optimized to minimize the use of physical space and energy. This type of server contains multiple thin, modular electronic circuit boards (or “blades“) which each contain a processor and memory. These are linked together in a chassis that provides power, cooling, networking, and other features needed to run a server.

Access Database is a type of database software developed by Microsoft that is used to create and manage databases. It stores data in tables, which are like spreadsheets, and allows users to query and report on the data in the tables. Access Database also includes features such as forms, reports, and macros, which can be used to automate tasks and simplify data entry.
