When data has been lost, a Cyclic Redundancy Check (CRC) Error occurs. CRC checks packets of information provided by devices by calculating from all data and comparing them to the data extracted, verifying their correctness.
Switches
A network switch is a device that passes data packets across devices. Switches transfer packets directly to devices rather than to networks, as routers do.
Understand
01
here is a great difference between knowing a thing and understanding it. You can know a lot and not really understand anything.
Learn
02
the capacity to learn is a gift; the ability to learn is a skill; the willingness to learn is a choice
Implement
03
Everyone can learn about things, but only a few can put them into practice.
