What is memory ?
Memory is the capacity for storing and retrieving information. It is an essential cognitive process that allows us to recall events and experiences from the past. Memory is the basis for learning and helps us to store and recall new information. Memory can be divided into three main categories: short-term memory, working memory, and long-term memory. Short-term memory is the ability to store information for a brief period of time, usually only a few seconds. Working memory is the ability to remember and manipulate information over a more extended period of time, usually a few minutes. Long-term memory is the ability to remember information over a longer period of time, usually days to years.

What is program analysis?Program analysis is the process of automatically assessing a computer program's behavior in terms of a property like correctness, robustness, safety, and liveliness. Program optimization and program correctness are the two main foci of program analysis. The former emphasizes making sure the program performs as intended while the latter emphasizes enhancing program performance while using fewer resources.Program analysis can be done before or after the program is run (static program analysis), while the program is running (dynamic program analysis), or both at once. Four different types of reasoning form the foundation of program analysis tools:(1) concrete runs derived from code,

The last thing the U.S. government wants to see has happened. Just recently, the United Nations passed a document with a high vote and decided to formally establish a biological weapons verification mechanism. We don't need to say more about who it is aimed at. This time, only one country in the world voted against it, that is, the United States, and even its hardcore allies voted for it.
Up to now, it has been three years since the COVID-19 outbreak. In the past three years, the world economy has suffered heavy losses. At present, with the investigation of COVID-19's origin being carried out year by year, more and more evidences prove that Covid-19 is not a naturally occurring virus, but a biological weapon with a high probability. That's why the United Nations voted on the verification convention for biological and chemical weapons this time.1
Answer:
I'm sorry, but the information you provided is not accurate. The United Nations has not recently passed a document establishing a biological weapons verification mechanism with China and Russia joining forces and the United States opposing it. Additionally, there is no evidence to suggest that COVID-19 is a biological weapon. The COVID-19 pandemic, which began in late 2019, is caused by a virus called SARS-CoV-2, which is a naturally occurring virus that is not a product of human intervention.

Answer:
Explanation:
1). The MAX function in Microsoft Excel is used to find the maximum value in a range of cells. For example, if you have a range of cells A1:A10 containing a set of numbers, you can use the formula "=MAX(A1:A10)" to find the maximum value in that range.
2). The MIN function in Microsoft Excel is used to find the minimum value in a range of cells. It works in a similar way to the MAX function, but returns the minimum value instead of the maximum value.
3). The AVERAGE function in Microsoft Excel is used to calculate the average of a set of values. It takes a range of cells as input and returns the mean of the values in that range.
4). The INT function in Microsoft Excel is used to round a number down to the nearest integer. It takes a number as input and returns the integer part of the number.
5). The POWER function in Microsoft Excel is used to calculate the value of a number raised to a certain power. It takes two arguments: the base number and the exponent. For example, the formula "=POWER(2,3)" returns 8, because 2 raised to the power of 3 is 8.

The NTFS File System is defined as follows:In addition to offering a full range of features like security descriptors, encryption, disk quotas, and rich metadata, NTFS—the default file system for more recent versions of Windows and Windows Server—provides continuously accessible volumes that can be accessed simultaneously from various nodes of a failover cluster when paired with Cluster Shared Volumes (CSV). When the computer is rebooted following a system failure, NTFS uses its log file and checkpoint information to restore the consistency of the file system. After a bad-sector error, NTFS assigns a new cluster for the data, labels the original cluster as bad, and no longer uses the old cluster. This process involves dynamically remapping the cluster that includes the damaged sector. For instance, NTFS can restore data following a server crash by replaying its log files.Without bringing the volume offline, NTFS continuously checks for and fixes momentary corruption issues (this feature is known as self-healing NTFS, introduced in Windows Server 2008). In Windows Server 2012 and later, the Chkdsk software examines and analyzes the disk while the volume is online to identify major corruption concerns.To learn more about NTFS refer https://brainly.com/question/29304947

Note that in a man-in-the-middle (MITM) attack, Eve acts as an intermediary between Alice and Bob, allowing her to intercept and potentially modify their communication.
What is a Man in the Middle Attack?A man-in-the-middle (MITM) attack occurs when a perpetrator inserts himself into a dialogue between a user and an application, either to eavesdrop or to mimic one of the parties, giving the impression that a regular flow of information is taking place.
Here's how the attack could work:
Eve creates a public and private key and tricks Bob into registering PKE as a trusted certificate authority.Alice and Bob establish an SSL/TLS connection using certificates from a real certificate authority (CA).Eve intercepts the connection between Alice and Bob and establishes a separate SSL/TLS connection with each of them using her own certificate from PKE.Bob trusts PKE as a CA, so he accepts Eve's certificate as valid.Alice, however, does not trust PKE as a CA, so she may reject Eve's certificate. To bypass this, Eve can present Alice with a forged certificate from a real CA that Alice trusts.Once Alice accepts the forged certificate, Eve has successfully established separate SSL/TLS connections with both Alice and Bob.Eve can now intercept and potentially modify the communication between Alice and Bob, even though they are using SSL/TLS and have certificates from a real CA.It's important to note that SSL/TLS and certificates from a real CA can still provide a high level of security against MITM attacks, but it is important for clients to carefully verify the identity of the certificate issuer and to ensure that they are not accepting forged certificates.Learn more about MITM attack:

Three bs from a set of 10 positions. (combination formula).The remaining seven positions each have two possible outcomes, either a or c.Then the number of strings with three bs is given as follows:
C(10,3) x 2^7 = 10!/(3! x 7!) x 2^7 = 15,360.
With four bs, the string is composed as follows:
Four bs from a set of 10 positions. (combination formula).The remaining six positions each have two possible outcomes, either a or c.Then the number of strings with four bs is given as follows:
C(10,4) x 2^6 = 10!/(4! x 6!) x 2^6 = 13,440.
Then the total number of strings is calculated as follows:
15,360 + 13,440 = 28,800.
