Options: a group of related fields, a map of the programmer's view of the data, an approach in which the top module is first tested then program modules are added from the highest level to the lowest level, a series or group of components that perform one or more operations of a more complex system
Options: A sequence is an object that generates a sequential series of unique numbers., Sequences are most often used to provide values for surrogate keys., NextVal and CurrVal are both sequence methods., Sequences guarantee valid surrogate key values.
Ethernet and Token-Ring are the two most commonly used network architectures in the world. Jim has heard of the different topologies for networks and wants to choose the architecture that will provide him with the most options. Which of the following would that be? Choose the most correct answer.
Options: Token-Ring because it currently can run at both 4Mbps and 16Mbps. This means that it can be used in any topology, Ethernet, because it is cabled using fiber-optic cable, Token-Ring, because it uses a MAU, Ethernet, because it can be set up with most topologies and can use multiple transfer speeds
Options: represents the information flow, documents rules, that select one or more actions, based on one or more conditions, from a set of possible conditions., gets an accurate picture of the system, shows the decision paths
Options: The secondary voltage for a step-down power transformer is greater than the primary voltage, The secondary current for a step-down power transformer is greater than the primary voltage, Parallel RLC circuit operated below its resonant frequency, purely resistive circuit
ENIAC (Electronic Numerical Integrator and Calculator) had huge advantage over Mark I because it used electronic valves in place of the electromagnetic switches. In the beginning, ENIAC was used for calculating the path of artillery shells. For which other was weapon design was it utilized?
Options: hydrogen bomb, atom bomb, agnimissile, fighter aircraft
