Bus network. A bus network follows the LAN topology, the place units in just one LAN are hooked up straight to a transmission line often called a bus. All indicators pass through all equipment, along with the receiver system recognizes the signals meant for it.
The difference between LEDs บริษัท รังรอง จำกัด and laser diodes is LEDs make incoherent gentle, though laser diodes create coherent mild. For use in optical communications, semiconductor optical transmitters has to be designed to be compact, effective and dependable, when functioning within an optimal wavelength range and straight modulated at large frequencies.
Most of the present day Online composition relies to the TCP/IP product, nevertheless there remain potent influences on the related but 7-layered open systems interconnection (OSI) model.
