In printing to a network printer, the next step after a print file is generated by an application is the GDI (graphics device interface) integrates information about the print file with information received from the printer driver.

A network printer may be defined as printer that is connected to a network, through Ethernet or Wi-Fi - the latter being the more contemporary option. Meanwhile, a local printer would be cabled straight to the tool that needed it, a network printer can access through multiple tools simultaneously on the same network.

Note that without the traditional need for virtual machines, containers can share access to an OS kernel. Partitioning from the 1960s and chroot process isolation from Unix in the 1970s are the foundations of container technology.

The trick with the cards was the parity scheme as it added bits (row and column of other cards) to make each direction even, making it an even parity scheme.

You can learn more through link below:

https://brainly.com/question/24194840#SPJ4

The required answer is the error card trick uses an odd parity scheme to detect errors in the sequence of bits represented by the deck of cards. The parity card, set based on the value of the data bits, helps identify whether an error has occurred by checking if the total number of bits with a value of 1 is odd or even.

The error card trick from the error detection lesson uses an odd parity scheme. In an odd parity scheme, an additional bit, called a parity bit, is added to a group of data bits. The parity bit is set in such a way that the total number of bits (including the parity bit) with a value of 1 is always an odd number.

In the error card trick, a deck of cards is used to represent a sequence of bits. Each card is assigned a value of 0 or 1, and the deck is arranged to form a sequence of data bits.

To implement the odd parity scheme, an additional "parity card" is introduced. The parity card represents the parity bit and is set based on the value of the data bits. If the total number of cards (including the parity card) with a value of 1 is even, the parity card is set to 1 to make the total odd. If the total number of cards with a value of 1 is already odd, the parity card is set to 0.

During the trick, the magician shows the deck of cards (including the parity card) to the audience and asks them to remember the sequence of bits. Then, the magician turns away and asks an audience member to secretly flip any one card, introducing an error into the sequence.

To detect the error, the magician checks the parity of the sequence. If the total number of cards with a value of 1 (including the parity card) is still odd, the magician knows that no error occurred. However, if the total number of cards with a value of 1 is now even, the magician can determine that an error has occurred. By revealing the flipped card, the magician can identify the position of the error.

By using the odd parity scheme, the error card trick effectively detects whether an error has occurred in the sequence of bits. If the parity of the bits is inconsistent, it indicates the presence of an error. This parity-based approach helps the magician identify the position of the error card and perform the trick successfully.

Therefore, the error card trick uses an odd parity scheme to detect errors in the sequence of bits represented by the deck of cards. The parity card, set based on the value of the data bits, helps identify whether an error has occurred by checking if the total number of bits with a value of 1 is odd or even.

When a collision happens in linear probing, we continue probing until an empty. Although linear probing is simple to compute, clustering is its biggest drawback.
