What is the importance of big O notation in programming?.

Answers

Its a mathematical notation that describes the limiting behavior of a function when the argument trends towards a particular value or infinity.

Answer:

Big O notation is a way to describe the efficiency of an algorithm in terms of the amount of time it takes to execute

Explanation:

For instance, let's say you have to calculate the amount of time an algorithm takes. There are a couple possible solutions that may come to mind:

- Start a timer when the algorithm starts running, and stopping it once it finishes. While this might seem like a good approach to the problem, it has a few flaws. For once, the time it takes is affected by a couple of different factors, such as: any other processes that the computer is running that may slow it down, or the computer's internal clock and tick speed.

- Another much better solution would be to count the number of steps executed. This is what Big O notation does. Regardless of outside factors, the number of steps an algorithm has stays fixed.

How do you calculate the square root on a calculator?.

Answers

There are many ways - it depends what buttons you have on your calculator.

If you have button “sqrt” - just use it :)
If you have buttons exp and ln tyope the number then ln multiply by 0.5 and then press exp
If you have just basic multiplication - use bisection to get to the results.
For example, you want to calculate sqrt of 10 - try middle point between 0 and 10 - it’s 5, 5*5 = 25 - oops too much, so let’s try middle point between 0 and 5, i.e.
2.5, 2.5*2.5=6.25, not enough, so now try middle between 2.5 and 5, i.e. 3.75:
3.75*3.75 = 14 - too much, so let’s take middle of 2.5 and 3.75, i.e. 3.125
3.125*3.125 = 9.76 - quite close but not enough
and so long until you reach a precision you wish to have, for example:
3.162277660168379 :)
alternatively you can go to the nearest shop and buy a decent calculator or use a computer you used to write this post :)

What technology would a bank's website use a scramble information as it is transmitted over the Internet

Answers

Answer:

Encryption technology helps provide secure transmission of information along the Internet by encoding the transmitted data

One commonly used technology is the Secure Sockets Layer (SSL) or its successor, Transport Layer Security (TLS).

Given that,

To find a bank's website one can use a scramble of information as it is transmitted over the Internet.

Now, SSL/TLS works by encrypting the data transmitted between a user's web browser and the bank's website.

This encryption prevents unauthorized access and ensures that the information remains confidential.

It uses cryptographic algorithms to scramble the data, making it extremely difficult for any potential attackers to decipher.

Hence, In addition to SSL/TLS, banks often implement other security measures such as firewalls, intrusion detection systems, and regular security audits to further protect sensitive information.

Administrative professionals often use queries to answer questions using the data in their database. What is a query? What are two possible queries you could use in a database?

Answers

Answer:

Queries.

Explanation:

Queries can perform many different functions in a database. Their most common function is to retrieve specific data from the tables. The data you want to see is usually spread across several tables, and queries allow you to view it in a single datasheet.

A database query is a way of requesting information from the database.

Regardless of the database or query language used, there are two primary types of queries that can be used for different goals:

-Select queries return information from one or more tables. While this is the most basic type of query, select queries can be used to specify how many results are returned, the order in which they appear, the source(s) used, and the parameters for a record to be included.

-Action queries perform a command on the data that has been retrieved, such as delete, alter, create, or update. This query allows a user to modify a large number of records in bulk instead of one at a time.
