So it is. also important to identify the critical parts. The parts directly affect the performance of. equipment performance and operations are known as critical parts of equipments. Each. equipment overall performance depend upon the condition of bearings. So these bearings. are treated critical parts.
The ISS has two, what might be called, networks. The mission critical network includes the computers and hardware that controls the ISS - communication equipment, Command and Control computers, PCS laptops that the crew uses to send command and look at data, controllers for heaters, radiators, solar panels, and so forth. This network uses the MIL-STD-1553 protocol and connections. This a very reliable but slow protocol that is used for controlling aircraft and missiles, among other equipment. The other network on the ISS is used for email, documents, mission timelines and so forth. I'm not as familiar with this network but I believe it uses the standard Ethernet protocols and connections. I think there is Wi-Fi as well.
