The research and development department at your office has been experimenting with different technologies to help improve the performance of the network. One group has been examining the use of a broadband network versus a based band network. Select the correct statement about broadband and baseband.
Broadband networks carry several channels on a single cable, whereas in a baseband network several cables carry one channel
Baseband networks carry a single channel on a single cable, whereas broadband networks carry several channels on a single cable
Baseband refers to local area networks, and broadband refers to wide area networks.
Baseband operates at a standard bit rate, whereas broadband may operate at different rates as needed
You have a class A network address 10.0.0.0 with 40 subnets, but are required to add 60 new subnets very soon. You would like to still allow for the largest possible number of host IDs per subnet. Which subnet mask should you assign?
An error-detecting code based on a summation operation performed on the bits to be checked.
A check bit appended to an array of binary digits to make the sum of all the binary digits.
a code in which each expression conforms to Specific rules of construction, so that if certain errors occur in an expression, the resulting expression will not conform to the rules of construction and thus the presence of the errors is detected
The ratio of the number of data units in error to the total number of data units
