The actual Cat 5 standard describes specific electrical properties of the wire, but Cat 5 is most widely Read More

Photoelectron spectroscopy is the study of energy and how it relates to matter in terms of absorption and production. Photoelectron spectroscopy observes both wavelengths and frequencies and is used to view the physical composition of chemicals and solids. It is used in both analytical and physical chemistry and astronomy in order to study an object’s physical properties and velocity by measuring the amount of energy being transferred to and from the object. Specifically, photoelectron spectroscopy measures how the absorption of electromagnetic radiation affects the electrons it produced. How does Photoelectron Read More

ATM (Asynchronous Transfer Mode) is a technological system developed for both local and wide area networks (LAN and WAN), and designed to handle data as well as video and voice traffic in real time, all at the same time. The system architecture makes use of switches that set up logical circuits at both ends of the data stream, which ensures unprecedented quality of service (QoS). Unlike conventional telephone switches that sets up dedicated end-to-end circuits, unused bandwidth in Asynchronous Transfer Mode (ATM) can be used for other purposes if needed. Read More
