In some texts, the interquartile range is defined differently. It is defined as the difference between the largest and smallest values in the middle 50% of a set of data. To compute an interquartile range using this definition, first remove observations from the lower quartile.
A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays. Relays are used where it is necessary to control a circuit by a separate low-power signal, or where several circuits must be controlled by one signal.
â¢ Describe the primary functionality traits of Frame Relay. â¢ Describe Frame Relay network implementation. â¢ Describe the format of Frame Relay frames. Frame Relay Introduction Frame Relay is a high-performance WAN protocol that operates at the physical and data link layers ofthe OSI reference model. Frame Relay originally was designed for use across Integrated Services DigitalNetwork (ISDN) interfaces.
