what is primary key? List any two advantage of it.​

Answers

Answer 1
A primary key is a column or set of columns in a database table that is used to uniquely identify each row in the table. It is a fundamental element of database design, as it ensures that each row in a table can be uniquely identified and helps to enforce the integrity of the data.

There are several advantages to using a primary key in a database table:

Uniqueness: A primary key ensures that every row in a table has a unique identifier, which makes it easier to distinguish one row from another.
Data integrity: A primary key helps to ensure that the data in a table is accurate and consistent, as it can be used to enforce relationships between tables and prevent data inconsistencies.
Performance: A primary key can be used to optimize the performance of a database, as it can be used to quickly locate and retrieve specific rows of data.
Data security: A primary key can be used to secure sensitive data in a database, as it can be used to control access to specific rows of data.

Load is down, the register is incremented, otherwise it is loaded with the

OUTDATA.

Answers

The steps to Build a sequential circuit that contains a register  is given below

The first step is to connect the 4-bit INDATA input to the data input of a 4-bit register.Next, we need to connect the Load and Enable inputs to a multiplexer. The multiplexer will be used to select between the INDATA input and the output of the register.The multiplexer output should be connected to the input of the register.We also need to create an AND gate that will be used to trigger the register on the falling edge of the clock. The AND gate should have the Clock input as well as the Enable input as its inputs.The output of the AND gate should be connected to the clock input of the register.The output of the register should be connected to the OUTDATA output.Create a NOT gate and connect the Load input to it, and connect the output of the NOT gate to one of the multiplexer input.Connect the output of the register to the second input of the multiplexer.

What is the design board about?

To build a sequential circuit that contains a register, we can use a combination of logic gates, flip-flops, and multiplexers.

In the above way, the register will be updated every clock cycle in which the Enable input is high. If the Load input is low, the multiplexer will select the output of the register and it will be incremented.

Otherwise, the multiplexer will select the INDATA input and the register will be loaded with the data asserted on the INDATA pin. The output of the register will be connected to the OUTDATA output, providing the register data.

Mr Wu has been going to work every day by taxi for many years. However, the taxi fare has been increasing rather quickly in recent years. Therefore, he is considering driving to work instead. One of the costs for driving is the parking fee. The parking rates of the car park at Mr Wu's workplace are as shown as below:

Weekdays:
$2 per hour between 4am and 7am
$1.20 per half hour between 7am and 6pm
$5 per entry after 6pm

Saturdays:
$2.50 per hour between 4am and 7am
$1.50 per half hour between 7am and 6pm
$7 per entry after 6pm

Sunday: Flat rate of $5 per entry

For all days, there is a grace period of 10 minutes.
The car park opens between 4am and 12 midnight daily. We assume vehicles are magically ejected at midnight.
There is a 10% surcharge on weekdays and a 20% surcharge on Saturdays for vehicles who park for more than 10 hours. There are no surcharges on Sunday.
There is an additional fee of $3 for exiting after 10pm on any day.
Your task is to write a function compute_fee(day, time_in, time_out) that computes the parking fee, where day is an integer between 1 and 7, with 7 representing Sunday, while time_in and time_out are integer values in a 24-hour format - e.g. 700 for 7am and 2359 for 11:59pm. Assume all input is valid.


Below are a few examples of how the fee is calculated:



Example 1: Tuesday, 4:29am to 7:50am.

• 4:29am to 7am is charged as 3 1-hour slots: $2.00 * 3 = $6.00

• 7am to 7:50am is charged as 2 30-minute slots: $1.20 * 2 = $2.40

• Total fee = $6.00 + $2.40 = $8.40



Example 2: Saturday, 7:01am to 7:49pm.

• 7:01am to 6pm is charged as 22 30-minute slots: $1.50 * 22 = $33.00

• 6pm to 7:49pm is charged as one entry: $7.00

• 20% Surcharge for parking more than 10 hours: ($33.00 + $7.00) * 20% = $8.00

• Total fee = $33.00 + $7.00 + $8.00 = $48.00


Example 3: Sunday, 3pm to 10:01pm.

• 3pm to 10:01pm is charged as one entry: $5.00

• Additional fee for exiting after 10pm: $3.00

• Total fee = $5.00 + $3.00 = $8.00


Example 4: Thursday, 11:49pm to 11:59pm.

• Grace period

• Total fee = $0.00


Example 5: Monday, 12pm to 10:01pm.

• 12pm to 6pm is charged as 12 30-minute slots: $1.20 * 12 = $14.40

• 6pm to 10:01pm is charged as one entry: $5.00

• 10% Surcharge for parking more than 10 hours: ($14.40 + $5.00) * 10% = $1.94

• Additional fee for exiting after 10pm: $3.00

• Total fee = $14.40 + $5.00 + $1.94 + $3.00 = $24.34

print(f"The average score is: {average_score:.2f}")

There are a few issues with your code.

First, the input function returns a string, not a number. You need to convert the input to a number using the float function before adding it to the int_accumulator.

Second, you have defined int_accumulator as an int, but you are trying to add floating point numbers to it. This will cause an error. Instead, you should define int_accumulator as a float to allow it to hold decimal values.

Finally, you have a typo in your code - int_accumilator should be int_accumulator.

Here is the corrected code:

score_list = [float(input("Judge No {} :score ".format(num+1))) for num in range(6)]
int_accumulator: float = 0
for score in score_list:
if score > 10:
print("I only like numbers within the 0-10 range !")
exit()
int_accumulator += score

print("the average score is ...", int_accumulator / len(score_list))

This should allow you to get the correct output.

How do big organizations take back their data to be reviewed after a disaster?

Answers

Here a 5 step recovery plan, I have been in IT for 8 years

1. Create a disaster recovery team.

The team will be responsible for developing, implementing, and maintaining the DRP. A DRP should identify the team members, define each member’s responsibilities, and provide their contact information. The DRP should also identify who should be contacted in the event of a disaster or emergency. All employees should be informed of and understand the DRP and their responsibility if a disaster occurs.

2. Identify and assess disaster risks.

Your disaster recovery team should identify and assess the risks to your organization. This step should include items related to natural disasters, man-made emergencies, and technology related incidents. This will assist the team in identifying the recovery strategies and resources required to recover from disasters within a predetermined and acceptable timeframe.

3. Determine critical applications, documents, and resources.

The organization must evaluate its business processes to determine which are critical to the operations of the organization. The plan should focus on short-term survivability, such as generating cash flows and revenues, rather than on a long term solution of restoring the organization’s full functioning capacity. However, the organization must recognize that there are some processes that should not be delayed if possible. One example of a critical process is the processing of payroll.

4. Specify backup and off-site storage procedures.

These procedures should identify what to back up, by whom, how to perform the backup, location of backup and how frequently backups should occur. All critical applications, equipment, and documents should be backed up. Documents that you should consider backing up are the latest financial statements, tax returns, a current list of employees and their contact information, inventory records, customer and vendor listings. Critical supplies required for daily operations, such as checks and purchase orders, as well as a copy of the DRP, should be stored at an off-site location.

5. Test and maintain the DRP.

Disaster recovery planning is a continual process as risks of disasters and emergencies are always changing. It is recommended that the organization routinely test the DRP to evaluate the procedures documented in the plan for effectiveness and appropriateness. The recovery team should regularly update the DRP to accommodate for changes in business processes, technology, and evolving disaster risks.



summary :an organization must develop a recovery team to create a disaster recovery plan that includes identifying and assessing disaster risks, determining critical applications, and specifying backup procedures. Other procedures may be included in the plan based on the organization. The recovery team and organization must then implement the DRP and follow through on the plan procedures. The DRP should be continually tested and maintained to consistently prepare the organization for evolving disasters and emergencies.

Note: You should be using dynamic programming to pass time limitation test.

Hint: You might find the following algorithm useful:

Initialize an empty table (dictionary), get the number of rows n and number of columns m.
Fill in the first row. For j in range m:
2.1 If maze[0][j] is safe, set table[(0, j)] to be 1 because there's one way to go there.
2.2 If maze[0][j] has a bomb, set table[(0, k)] where k >= j to be 0. Since one cell is broken along the way, all following cells (in the first row) cannot be reached.
Fill in the first column. For i in range n:
3.1 If maze[i][0] is safe, set table[(i, 0)] to be 1 because there's one way to go there.
3.2 If maze[i][0] has a bomb, set table[(i, 0)] and all cells under it to be 0. The reason is same as for the first row.

Main dynamic programming procedure - fill in the rest of the table.
If maze[i][j] has a bomb, set table[(i, j)] = 0.
Otherwise, table[(i, j)] = table[(i - 1, j)] + table[(i, j - 1)]
Return table[(n - 1, m - 1)]
