2 OSI Model / OSI Stack Flashcards
- The Open Systems Interaconnect Model is also known as the OSI reference model (T/F)
- The OPI Model is useful for troubleshoot (T/F)
- OPI Model csn be used on different technologie, devices, and manufacturers. (T/F)
True

Networks are designed to make data to do what? Layer 5-7
To make data flow across networks.
Where transmission of bits across the network occurs and includes physical and electrical network characteristics
Physical LAyer
If it charges during the clock cycle, then a 1 is represented (otherwise, a 0 is represented)
Transition Modulation
what uses voltage (0V for 0, +5V/-5V for 1)?
