SDRAM, or Synchronous Dynamic Random Access Memory, is a type of RAM in which memory is synchronized with the computer’s internal system bus via the use of a clock system. While SDRAM requires that data must wait for a predetermined number of clock signals before it is sent to the memory array, new data can be interpreted during this time and all data is sent as one packet, allowing for higher data speeds. This process is the foundation of pipelining and has revolutionized file access speeds in both personal and Read More

An inductor is a conducting coil, wrapped around a core, that creates inductance when an alternating current flows through it. Inductors are used to impede the flow of current in a circuit. The conductor is usually thin magnet wire, and the core is usually air or steel. Working of an Inductor When the alternating current flows through an inductor, it creates an electromagnetic field. The strength of this field depends on number of coils, the coil diameter and the permeability of the core material. Steel has a much higher permeability Read More
