```python
def split_check(bill, people, tax_percentage=0.09, tip_percentage=0.15):
   total_bill = bill * (1 + tax_percentage)
   tip_amount = bill * tip_percentage
   total_cost = total_bill + tip_amount
   cost_per_person = total_cost / people
   return cost_per_person
```
This function takes in fours: parameter `bill`, `people`, `tax_percentage`, and `tip_percentage`. `bill` is the total amount of the bill, `people` is the number of diners to split the bill between, and `tax_percentage` and `tip_percentage` are optional percentages for tax and tip, respectively. If they are not provided, the default values of 0.09 and 0.15 will be used.
The function first calculates the total bill by adding the tax to the original bill. It then calculates the tip amount by multiplying the original bill by the tip percentage. Finally, it adds the tip amount to the total bill and divides by the number of people to get the cost per person.

b. Session hijacking is an attack that relies on guessing the ISNs of TCP packets.

Session hijacking is a type of attack that aims to take control of an established session between a client and a server. In this attack, an attacker attempts to hijack or take over an existing session by intercepting and manipulating the communication between the client and the server.

One common way to perform session hijacking is by guessing or predicting the Initial Sequence Number (ISN) of the TCP packets that are exchanged during the session establishment process. The ISN is a randomly generated value used to initiate a TCP connection, and it is used to ensure the uniqueness and integrity of the packets exchanged between the client and server.

The crude death rate for Leon County is 4.000 deaths per 1,000 population.

To calculate the crude death rate for Leon County, you need to divide the number of deaths by the total population and multiply by 1,000. Let's assume that there were 200 deaths in Leon County in the past year, and the total population is 50,000.

The formula for the crude death rate is:

Crude Death Rate = (Number of deaths / Total population) x 1,000

Plugging in the values, we get:

Crude Death Rate = (200 / 50,000) x 1,000

Crude Death Rate = 4.000 (rounded to three decimal places)

A "precise interrupt" is always associated with an exact instruction in pipelined computers. In pipelined computers, multiple instructions are executed simultaneously by dividing them into smaller stages that can be executed in parallel.

In computer architecture, a precise interrupt is an exception that is associated with an exact instruction in a pipelined processor. When an instruction causes an exception, the processor knows exactly which instruction caused the exception, allowing the system to handle the exception more efficiently. Precise interrupts can be handled easily by the processor, as it can easily determine the exact instruction that caused the exception and can resume execution from the correct point. This makes precise interrupts ideal for real-time systems, where timing and response are critical. Precise interrupts are used in many modern processors, including x86 and ARM architectures, to provide reliable and efficient exception handling.

The POP3 service uses port 110. The POP3 (Post Office Protocol version 3) service uses port 110 by default. This port is used by email clients, such as Microsoft Outlook and Mozilla Thunderbird, to retrieve email messages from a remote email server.

When a user configures their email client to use POP3, the client connects to the email server on port 110 and retrieves any new email messages that have been delivered to the user's mailbox. The email client then downloads these messages to the user's computer or device, where they can be read and managed offline.

While port 110 is the default port for POP3, it is important to note that some email providers may use a different port for POP3 or may require the use of encryption (such as SSL or TLS) for security reasons. In these cases, the user may need to configure their email client to use a different port or to enable encryption in order to access their email account.

The base-8 number system is known as the "octal" number system. It uses eight digits to represent values from 0 to 7. Each octal digit can be represented using only three bits, which makes it useful in digital systems where space is at a premium.

One of the most common uses of octal numbers is in representing UNIX file permissions. In UNIX, files and directories have three sets of permissions: owner, group, and other. Each set consists of three permissions: read, write, and execute. These permissions can be represented using octal numbers, where each digit represents the sum of the permissions for that set. For example, the permission "rwxr-xr--" would be represented in octal as "755". The first digit represents the owner permissions (rwx), which add up to 7. The second digit represents the group permissions (r-x), which add up to 5. The third digit represents the other permissions (r--), which add up to 5.Using octal numbers to represent permissions makes it easy to set and manipulate permissions using simple arithmetic operations. For example, adding the octal number "2" to a permission digit will add the "write" permission, while adding the octal number "1" will add the "execute" permission.

In a high-performance router, shadow copies of the routing table are kept in all of the above: the input ports, the output ports, and the switching fabric.

The purpose of keeping shadow copies of the routing table is to ensure that the forwarding decisions are made quickly and efficiently. By having a copy of the routing table in each of these locations, the router can quickly determine the correct output port for incoming packets. This also reduces the amount of traffic that needs to be sent to the central processing unit (CPU) for forwarding decisions, allowing the router to operate at high speeds. Additionally, having shadow copies of the routing table provides redundancy, ensuring that the router can continue to operate in the event of a failure in one of the components.

True. Using an alias is necessary when you join a table to itself in order to avoid confusion and ambiguity. When you join a table to itself, you essentially create two copies of the same table, and if you refer to columns using the table name alone, it is unclear which table you are referring to.

For example, if you have a table named "employees" and you want to join it to itself to find all pairs of employees who have the same manager, you would need to use aliases to distinguish between the two copies of the "employees" table. You could use "e1" and "e2" as aliases for the two copies of the table, and then refer to columns using the appropriate alias. Using aliases not only clarifies the syntax of the SQL statement but also helps to make it more readable and understandable for others who may need to work with the code in the future. It is a best practice to always use aliases when joining a table to itself or when joining multiple tables together in a single query.

Yes, the data hazard is caused by the fact that i2 requires the result of i1's calculation (stored in $s0) as one of its inputs.

The solution of "forwarding" allows the result to be directly passed from i1's stage 3 to i2's stage 3, avoiding a stall in the pipeline. The ALU's input in this case refers to the inputs required for the Arithmetic Logic Unit to perform the calculation, which in i2's case includes the value stored in $s0.In computer architecture, a data hazard occurs when there is a conflict between two or more instructions that require the use of the same data at the same time. Data hazards can cause errors, incorrect results, or delays in program execution. There are three types of data hazards: read-after-write (RAW), write-after-read (WAR), and write-after-write (WAW). A RAW hazard occurs when an instruction tries to read data that is not yet available because it is still being processed by a previous instruction. A WAR hazard occurs when an instruction tries to write to data that has not yet been read by a previous instruction. A WAW hazard occurs when two instructions try to write to the same data at the same time. To prevent data hazards, techniques such as forwarding, pipelining, and reordering are used in modern computer processors.
