This is accomplished by having the destination computer transmit acknowledgement data packets to the source computer on a regular basis, letting the source computer know how much of the message it has received and decoded.
How are data packets sent?A network packet operates by selecting the most efficient path to its destination. All of the other packets in a message follow this path, which increases the efficiency of network traffic in terms of distributing a load among various pieces of hardware.
How do packets know how to reach where they're going?When a router gets a packet, it checks its routing table to see if the destination address points to a device on one of the networks to which it is connected, or if another network must be used to send the message.

the first-fit memory allocation algorithm is slower than the best-fit algorithm (on average). select one: true false
It is false that the first-fit memory allocation algorithm is slower than the best-fit algorithm (on average).
The operating system must maintain a list of each memory location, noting which ones are free and which ones are busy, for both fixed and dynamic memory allocation schemes. The available partitions must then be assigned as new workloads are added to the system.
Allocating Memory First-Fit:
The free/busy list of tasks is maintained using this strategy, which maintains low-ordered to high-ordered memory organization. This method assigns the first work the first memory space that is greater than or equal to its size. Instead of looking for a suitable partition, the operating system simply assigns the task to the closest memory partition that is large enough.

what is the commonly used casting function for casting the pointer to different objects of the classes in an inheritance hierarchy? group of answer choices
To change pointers or references within an inheritance structure, use a dynamic_cast. The standard casting function for casting the pointer to various objects is static_cast. Use this function for simple type conversions.
An object that stores a memory address is known as a pointer in computer science and is used in many programming languages. Another value stored in computer memory or, in some situations, memory-mapped computer hardware may be the source of this. When a pointer accesses a location in memory, it is known as dereferencing the pointer to retrieve the value that is kept there. A page number in a book's index may be compared to a pointer to the relevant page; dereferencing such a pointer would include turning to the page indicated by the provided page number and reading the text there. Depending on the underlying computer architecture, a pointer variable's actual format and content may differ.

adding one disk to the towers of hanoi problem doubles the number of disk moves required to solve it. group of answer choices true false
False; (2n -1) is formula for adding one disk to the towers of Hanoi problem doubles the number of disk moves.
Towers of Hanoi has an exponential complexity of 2n - 1, meaning that when n goes up by 1, there are twice as many moves, or an exponential increase in complexity. The Towers of Hanoi solution calls for utilizing the prior technique twice plus an additional move. It only needs one move to be solved for one disk. It requires utilizing the answer for 1 disk twice plus 1, or 1 move + 1 move + 1 move, which is 3 moves, to solve it for 2 disks. In the equation 2n - 1, where n is the number of disks, we can express this. If (n > 0) is initially true, it will continue to be true because in the recursive scenario, the method calls itself with the same parameter. As a result, n does not change.

The ability to print money is reserved for the federal government. The government lowers the value of money and raises the inflation tax by printing money to pay its debts.
According to the Constitution, only the federal government has the authority to print money. This guarantees that there is a stable medium of exchange in every state, enabling unhindered trade in goods and services between them.
The value of the currency falls when the government produces money to pay off its debt because there is a greater supply of money than there is demand for it. As a result, the currency will only be able to purchase a smaller quantity than it could previously, producing a form of inflation tax because individuals will have to pay more to buy goods and services.

Here, a 16-bit binary number is converted to a serial in-serial-out shift register. For this design, we must utilize 16 74LS76JK flip-flop stages, NAND gates for any necessary inverters, and a signal with a 1Hz frequency.
Additionally, to manually shift the bits into the subsequent device, a switch is typically used to manually flip the input of the shift register. Examine the Shift Register's output waveform using a digital oscilloscope.
This is an N-bit flip flop with N stages because we need 16 bits, thus we added 16 stages as seen in the above diagram.

One set of credentials for the user, less overhead associated with password assistance, less likely that passwords will be written down, and less time spent re-authenticating to services.
With single sign-on (SSO) authentication, users can securely authenticate with multiple websites and applications using a single set of credentials. The foundation upon which SSO operates is a trust relationship that is established between an application, which is referred to as the service provider, and an identity provider, such as OneLogin. This trust relationship frequently rests on a certificate that is exchanged between the identity provider and the service provider. When identity information is sent from an identity provider to a service provider, this certificate can be used to sign it, ensuring that the service provider is aware that the information comes from a well known source. In SSO, identity data is stored using tokens that contain user-identifying information like an email address or username. Single-sign-on (SSO) authentication is required more than ever before. Almost every website today requires some form of authentication before users can access its features and content.
