The advantage of a command processor running only built-in commands is:
Options: flexibility to the users in running lists of commands by simply collecting them in named batch command files, the command set being common across different hardware configurations, users can create system programs and run them as commands, the processing is much faster than would other-wise be the case when user defined commands are used

An information processor includes
Options: the data base and the model base, the central processing unit, incoming data and outgoing information, incoming data, the central processing unit, the model base, outgoing information, and the data base
Options: One or more conductors that serve as a common connection for a related group of devices, a continuous frequency capable of being modulated or impressed with a second signal, the condition when two or more stations attempt to use the same channel at the same time, a collection of interconnected functional units that provides a data communications service among stations attached to the network
How does a host on an Ethernet LAN know when to transmit after a collision has occurred? In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously. In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting. You can improve the CSMA/CD network by adding more hubs. After a collision, the station that detected the collision has first priority to resend the lost data. After a collision, all stations run a random backoff algorithm. When the backoff delay period has expired, all stations have equal priority to transmit data.
Options: means storing records in contiguous blocks according to a key., Stores records sequentially but uses an index to locate records, uses an index for each key type, has records placed randomly throughout the file
Options: always increases as the applied frequency increases, is equal to the sum of the values of resistance, inductive reactance and capacitive reactance, always decreases as the applied frequency increases, is maximum at the resonant frequency
