To understand data communication in the network is complex. In this article I’ll easy demonstrate how two computer get connect each other, transfer and receive data information also with the Tcp/IP five layer protocol.   What is Data communication? The term “data communication” i...

Managed switches are superior to unmanaged ones in terms of functionality, but they necessitate the expertise of an administrator or engineer to fully realize their potential. More precise management of networks and their data frames is made possible by using a managed switch. On the other hand, ...

Light waves are electromagnetic radiation generated by electrons in the process of atomic motion. The movement of electrons in atoms of various substances is different, so the light waves they emit are also different. Spectrum is a pattern of monochromatic light separated by a dispersion system (...

Concept explanation: Ethernet is the most common communication protocol standard adopted by the existing LAN. The Ethernet network uses CSMA/CD (Carrier Sense Multiple Access and Conflict Detection) technologies. Ethernet dominates LAN technologies: 1. Low cost (less than 100 Ethernet network car...

How to access and control different computer devices through media in the LAN is preliminarily understood as follows. A long time ago, Ethernet was used to connect all lines of home computers to the bus to realize the mutual communication of computers. When using this method to send data, you nee...

1、 Operating temperature The operating temperature of the optical module. Here, the temperature refers to the housing temperature. There are three operating temperatures of the optical module, commercial temperature: 0-70 ℃; Industrial temperature: – 40 ℃ – 85 ℃; There is also an exp...
