Which one of the following statements is true for voltage in a parallel circuit?
Options: The total voltage in a parallel circuit is equal to the average value of the individual voltages, The total voltage in a parallel circuit is always less than the value of the smallest voltage, The total voltage is equal to the sum of the voltages across the individual branches in a parallel circuit, The total voltage of a parallel circuit is the same as the voltages across each branch
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 sections 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
If delays are recorded as 10 bit numbers in a 50 router network, and delay vectors are exchanged twice a second, how much bandwidth per fill duplex line is occupied by the distributed routing algorithm?
Options: have both their operands in the main store., which perform an operation on a register operand and an operand which is located in the main store, generally leaving the result in the register, expect in the case of store operation when it is also written into the specified storage location., which perform indicated operations on two fast registers of the machine and have the result in one of the registers, all of the above
Options: The Addresses Resolution Protocol, ARP, allows a host to find the physical address of a target host on the same physical network, given only the target IP address., The sender's IP - to- physical address binding is included in every ARP broadcast; receivers update the IP-to-Physical address binding information in their cache before processing an ARP packet., ARP is a low-level protocol that hides the underlying network physical addressing, permitting us to assign IP-addresses of our choice to every machine., All of the above
. All of the following are task performed by the operating system except
Options: a. Managing hardware on the computer
b. Controlling the access that application program has to the CPU
c. Performing housekeeping task like file compression and disk defragmentation
d. Provides an interface for user to interact with computer
