When a page hit occurs, the CPU performs several steps to retrieve the requested data from the memory.
Firstly, it checks the page table to identify the physical address of the required page. Once the physical address is located, the CPU sends a request to the memory controller to fetch the data from the memory. The memory controller then retrieves the data from the physical address and sends it back to the CPU through the cache. The CPU checks the cache to see if the data is already present, and if it is, the data is quickly retrieved from the cache. However, if the data is not present in the cache, then the CPU has to wait for the data to be fetched from the memory.

5. Explain one reason why you might experience long response times in getting a Web page from a server in your own city.
One reason why someone might experience long response times in getting a web page from a server in their own city is network congestion.
Network congestion occurs when there are too many users trying to access the same network resources at the same time, resulting in a slowdown or delay in the transmission of data. This can happen due to various reasons, such as a sudden increase in the number of users or devices trying to access the network, outdated network infrastructure, or inadequate bandwidth. In such cases, the traffic needs to be prioritized, and data needs to be transmitted in a queued manner, which can cause significant delays in response times. Furthermore, other factors such as server overload or software/hardware issues could also cause delays in response times even if the server is located in the same city.

The given statement "A transaction is the complete set of closely related update commands that must all be done, or none of them done, for the database to remain valid" is true because it describes the properties of a transaction.
A transaction is a unit of work that consists of one or more database operations, such as inserts, updates, or deletes. All the operations within a transaction must be completed successfully or none of them should be done at all. This is known as the atomicity property of a transaction.
The operations within a transaction should also be consistent with the integrity constraints of the database, and the final state of the database should be valid. This is known as the consistency property. Additionally, once a transaction is committed, its effects should be permanent, and it should not be possible to roll back the changes.
This is known as the durability property. Finally, transactions should be isolated from each other, and their effects should not interfere with each other. This is known as the isolation property.

Which type of attack does the use of HMACs protect against?
HMACs (Hash-based Message Authentication Codes) are cryptographic algorithms used to ensure the integrity and authenticity of a message by verifying its authenticity and detecting any tampering or alterations. In other words, HMACs protect against message forgery and tampering attacks.
In a message forgery attack, an attacker tries to impersonate a legitimate sender and send a message to a receiver. This type of attack can lead to the recipient trusting the message and acting on it, even though it is not authentic. However, HMACs can prevent such attacks by ensuring that the message received by the recipient is the same as the one sent by the sender, thereby establishing its authenticity.
Tampering attacks, on the other hand, involve modifying the message in transit, either to change its content or to change its destination. These attacks can be detrimental to the integrity of the message, and the receiver may end up taking the wrong action based on the modified message. However, with HMACs, it becomes easy to detect any such modifications since the receiver can validate the message using the shared key, and if the message has been tampered with, the validation fails, and the receiver can discard the message. Therefore, HMACs are a powerful tool that can protect against message forgery and tampering attacks, and they play an essential role in ensuring the security of messages transmitted over the internet.
