A microprocessor is a computer processor where the data processing logic and control is included on a single integrated circuit, or a small number of integrated circuits. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer’s central processing unit. The integrated circuit is capable of interpreting and executing program instructions […]
Pittsburgh is a city in the state of Pennsylvania in the United States and the county seat of Allegheny County. The city developed as a vital link of the Atlantic coast and Midwest, as the mineral-rich Allegheny Mountains led to the region being contested by the French and British empires, Virginians, Whiskey Rebels, and Civil War raiders. Pittsburgh has transformed into a hub for the health care, education, and technology industries. Pittsburgh is
Secure communication is when two entities are communicating and do not want a third party to listen in. In order for this to be the case, entities need to communicate in a way unsusceptible to eavesdropping or interception. Secure communication includes means by which people can share information with varying degrees of certainty that third parties cannot intercept what

Sanitation refers to public health conditions related to clean drinking water and ‘treatment and disposal of human excreta and sewage.’ Preventing human contact with feces is part of sanitation, as is hand washing with soap. Sanitation systems aim to protect human health by providing a clean environment that will stop the transmission of disease, especially
Automation describes a wide range of technologies that reduce human intervention in processes. Human intervention is reduced by predetermining decision criteria, subprocess relationships, and related actions — and embodying those predeterminations in machines. Automation, includes the use of various equipment and control systems such as machinery, processes in factories, boilers, and heat-treating ovens, switching on telephone networks; steering and stabilization of ships, aircraft, and other applications and vehicles with
Celeron, Pentium, and Core i3/5/7 are all marketing brand names by Intel. They are not guaranteed to relate to any particular hardware specification or performance. In particular a ‘Core i5′ in an ultra-slim laptop will usually be lower performance than a ‘Core i5′ in a bulky gaming laptop which in turn is lower performance than

Wireless communication (or just wireless, when the context allows) is the transfer of information between two or more points that do not use an electrical conductor as a medium by which to perform the transfer. The most common wireless technologies use radio waves. With radio waves, intended distances can be short, such as a few meters for Bluetooth or as far as millions of
A low-power wide-area network (LPWAN) or low-power wide-area (LPWA) network or low-power network (LPN) is a type of wireless telecommunication wide area network designed to allow long-range communications at a low bit rate among things (connected objects), such as sensors operated on a battery. The low power, low bit rate and intended use distinguish this type of network from a wireless WAN that is designed to connect users or businesses, and carry

LoRa (Long Range) is a proprietary low-power wide-area network modulation technique. It is based on spread-spectrum modulation techniques derived from chirp spread spectrum (CSS) technology. It was developed by Cycleo of Grenoble, France and acquired by Semtech, the founding member of the LoRa Alliance; it is patented.
Cryptography, or cryptology, is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages; various aspects of information security, such as data confidentiality, data integrity, authentication, and non-repudiation, are central to modern cryptography. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, electrical engineering, communication
