Answer:
s = input("Input a float: ")
print("{:12.2f}".format(float(s)))
Explanation:
- Read a number from user using the input function of Python.
- Use the format function of Python to correctly format the output according to the given requirements.
- Note: Use Python 3.6 or above for this code to run without any issue.
Output:
Input a float: 1234.56789
1234.57
Depends on how deep you're willing to go to really,
You need one of a few arrangements of flip flop circuits to keep 1-bit state.
Going deeper, you need either NAND, or NOR gates(or a bunch of other ones) and connectors.
Even deeper, you'll require diodes or transistors to build the logic gates.
Beyond that is particle physics.
The term vulnerability describes the issue that Adam discovered.
b. vulnerability
<u>Explanation:</u>
SQL injection attack is an attack in which an external party can execute SQL commands on the database that serves as a back-end for a particular website. The SQL commands can be used to modify the contents of the website, modify the records, delete the records, and retrieve confidential information as well.
As Adam believes that the code has an issue that allows a SQL injection attack, the term that best describes the issue that he discovered is vulnerability. The website is vulnerable since the code does not have a proper procedure to tackle a situation of SQL injection attack.
Answer:
Crosstalk, Jitter, Impulse noise.
Explanation:
Crosstalk is a network error that occurs when one pair of cable causes interference on another pair of cables thereby preventing efficient data transmission.
Jitter may also impair the accuracy of the data being transmitted across network because minute variations in amplitude, phase, and frequency always occur. The generation of a perfect carrier signal in an analog circuit is almost impossible. The signal may be affected by continuous and rapid network gains or phase changes.
Impulse noise (also referred to as spikes) is the primary source of errors in data communications. Impulse noise can be caused by positioning a communications cable near a source of intermittent but strong electromagnetic pulses, such as an elevator motor.
Counter measures
Shielding (protecting wires by covering them with an insulating coating) is one of the best ways to prevent impulse noise, cross-talk.
Amplifiers can be used to increase signal strength since the connection would run across 4 floors.
Answer:
1, 3, & 4.
Is the way to do so. Good luck.
