Answer:
rows and columns, or matrix
Explanation:
Two-dimensional 2D arrays are being indexed with the help of two subscripts. The first one is for the row and the second one if for the column. And each of the elements of the 2D array must be of the one kind like they all can be an object type or they all can be of primitive type.
Like:
int A[3][3];
The above is the 2-dimensional array in C++, and elements are of type int, which is a primitive data type.
In a polling-based network receives, the operating system keeps checking the status register after a fixed time interval to see whether a device needs hardware attention or not. CPU gradually checks the status of receive bit after a defined time interval of a clock and if the value of receive bit is true then data is moved from the RX register to the memory. In interrupt-based networks, whenever a device needs hardware processing then an interrupt is raised to inform the CPU for device attention. The data of the device is transferred to memory from the network card.
Polling is a protocol, not a hardware mechanism where the device gets attention by CPU. An interrupt is a hardware mechanism, not a protocol where the device gets attention by the interrupt handler. In polling, during receiving, parts of received data need to transfer to memory but in case of interrupts, whole data is transferred at once after receiving is done. An interrupt is a heavy operation as compared to pooling because hardware involves in it. For large amounts of data, Polling becomes an inefficient method. In polling, CPU gradually checks devices at regular intervals whereas the Interrupt handler can send interrupt at any time. Each device has its own Command ready bit which indicates whether the device requires servicing or not. In polling, CPU wastes numerous clock cycles by repetitively checking the command-ready little bit of each device. In Interrupt based network, the interrupt request line indicates whether the device requires servicing or not. In interrupt-based network, CPU cycles not wasted but CPU is disturbed only when device send interrupt signals.
Relative performance between programmed I/O and DMA:
For determining the relative performance between programmed I/O and DMA, important factors are:
1. Size of data
2. Frequency of operations
Correct answer choices are:
Requires a credit check
Includes interest rate information
Requires a signature for rent-to-own agreements
Contract finance is that the name was given to a debt that's provided after signing a legal contract document that your business has won and also the cash should be accustomed to complete the contract work.
The unbound form with menu options for navigating a database is B. a switchboard
An unbound form does not contain a RecordSource, that does not mean it cannot have data, but the programmer will have to bring that data in manually, where a bound form is automatically associated with some data.
