the ________, also known as the address operator, returns the memory address of a variable.
Answer: &
Explanation: In some programming languages like C, the ampersand (&) is known as the address operator.
An ampersand is used to denote the unary operator known as the address-of operator (&).
What is the address operator?To find the memory address of any variable in your script, use the address operator, a unary operator. There should be no space between the operator and the variable name. The address operator can be used to send a variable's address as a parameter in a function call or to assign the address of a variable to a pointer variable. The address may be sent to C applications, who can then use it just like any other normal C pointer.
The C++ language has a technique called an address-of operator that yields a variable's memory address. These addresses that the address-of operator returns are referred to as pointers since they "point" to the memory location of the variable. Because it provides a reference to a variable by referencing its memory location, the & is known as the reference operator. The * operator, which dereferences a reference, offers us the value pointed to by a pointer. This allows us to access the value rather than the address of a memory location.
Therefore, The unary operator known as the address-of operator is shown by an ampersand (&).

The measure of GDP (Nominal or Real) is a more accurate reflection of output is Real GDP.
Why do i say Real GDP?Real GDP is a more accurate reflection of output because it takes into account changes in the price level. Nominal GDP is one that do measures the value of economic output using current prices, but these prices may be affected by inflation or deflation, which can distort the measure of output.
Therefore, one can say that Real GDP, on the other hand, is adjusted for changes in the price level by using a base year price index, such as the consumer price index (CPI). This tends to allows for a more accurate comparison of output over time, as it eliminates the impact of changes in the price level.

Say that a write-once Turing machine is a single-tape TM that can alter each tape square at most once (including the input portion of the tape). Show that this variant Turing machine model is equivalent to the ordinary Turing machine model. (Hint: As a first step, consider the case whereby the Turing machine may alter each tape square at most twice. Use lots of tape.)
We demonstrate how a write-twice TM can be used to replicate a regular TM before constructing a try writing TM from the write-twice TM.
The write-twice TM duplicates the entire tape to a new section of the tape to the right of the section that was used to hold the input, simulating one step of the original machine. Each tape square is changed twice throughout the copying process—once to write the character for the first time and again to signify that it has been copied, which happens on the following step when the tape is recopied. The tape content is updated based on when the cells at or near the designated spot are copied.
This copying process can be thought of as simulating one phase of an ordinary TM since while replicating the cells at or near the designated point, the tape content is changed in accordance with the original TM's regulations. (Slightly technical note: We also need to know where the tape head for the original TM is located on the duplicated symbol.)
Function precisely as previously, with the exception that each column on the prior tape is now represented by two cells, to execute the simulation using a write-once machine. The first of these contains the tape symbol for the original machine, while the secondary is for the sign applied during copying. As a result, the computer does not receive the input in the format with two cells per symbol. The duplicating markings are placed directly above the input symbol during the first tape copy.

what type of ipv6 address is fe80::8cf1:2c42:ffde:da1c?
The type of ipv6 address, fe80::8cf1:2c42:ffde:da1c is link local address. A link-local address in computer networking is the IP address that should be used for communication inside a logical division of the network.
A link-local address in computer networking is a unicast network address that is only usable for communications with other hosts linked to the same subnetwork. The method of stateless address autoconfiguration, also known as link-local address autoconfiguration or auto-IP, is most frequently used to automatically assign link-local addresses.
Beyond their network segment, link-local addresses are not guaranteed to be singular. Routers do not, therefore, forward packets with link-local source or destination addresses.
Administrators can manually allocate link-local addresses or operating systems can do so automatically.

1.bob has received an order (digitally signed) for material from alice, and alice claims she never sent one. how does bob prove the order came from alice? explain how the parties would enact this cryptographically and the basis for each step.
Alice cannot deny sending the message if she signs it with her private key, and transmits it to Bob, and Bob then uses Alice's public key to verify the signature.
What is the public key?The area of cryptographic systems that use pairs of related keys is known as public-key cryptography, also known as asymmetric cryptography.
A public key and its accompanying private key make up each key pair. Cryptographic algorithms that are based on one-way functions are used to create key pairs.
The private key must be kept hidden in order for public-key cryptography to be secure; nevertheless, security is not compromised if the public key is freely distributed.
Anyone with access to a public key can encrypt a message in a public-key encryption system, creating a ciphertext.
However, only those who have access to the associated private key can decrypt the ciphertext to reveal the original message.
So, in the given situation, if Alice uses her private key to sign the message and sends it to Bob, Bob can use Alice's public key to confirm the signature, so Alice cannot claim not to have sent the message.
Therefore, Alice cannot deny sending the message if she signs it with her private key, and transmits it to Bob, and Bob then uses Alice's public key to verify the signature.

calculate the overall speedup of a system that spends 40% of its time waiting on i/o disk service with a disk upgrade that provides for 150% greater throughput. express the speed up as a percentage (rounded up to no digits after the decimal point).
The overall speedup of the system due to the disk upgrade is 60%.
How to calculate the disk upgrade percentage?The speedup of the system due to the disk upgrade can be calculated as follows:
First, let's calculate the amount of time the system spends waiting on I/O disk service before the upgrade:
Time waiting on I/O disk service before upgrade = 40% * Total time = 40% * 1 = 0.4
Next, let's calculate the amount of time the system spends waiting on I/O disk service after the upgrade, assuming the disk provides 150% greater throughput:
Time waiting on I/O disk service after upgrade = 40% * 1 / (1 + 150%) = 40% * 1 / 2.5 = 16%
The overall speedup of the system due to the disk upgrade can now be calculated as follows:
Overall speedup = 1 - Time waiting on I/O disk service after upgrade / Time waiting on I/O disk service before upgrade = 1 - 16% / 40% = 1 - 0.4 = 60%
Therefore, the overall speedup of the system due to the disk upgrade is 60%.
