Answer:

Option B i.e., False.

Explanation:

The weakness, KRACK tricks a wifi access points to reuse an in-use encryption, enabling the intruder to decode and interpret data intended to remain encrypted. Wireless communication encrypts, that decrypt unencrypted wireless network activity and expose sensitive data.

So, the following scenario is false about the wireless attack.

On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of f0 * rn, where n is the distance

Stels [109]

Answer:

#include <stdio.h>

int main()

{

float your_value1, your_value2, your_value3, your_value4, your_value5;

printf("Enter a frequency: ");

scanf_s("%f", &your_value1);//storing initial key frequency in your value 1

float r = 2.0 / 12;//typing 2.0 so it is treated as float and not int

your_value2 = your_value1 * r * 1; //initial*r*n

your_value3 = your_value1 * r * 2; //initial*r*n

your_value4 = your_value1 * r * 3; //initial*r*n

your_value5 = your_value1 * r * 4; //initial*r*n

printf("%0.2f %0.2f %0.2f %0.2f %0.2f", your_value1, your_value2, your_value3, your_value4, your_value5);

return 0;

}

Explanation:

The purpose of this exercise is to make you understand the difference between float and int. float variables are used when you need decimals in your calculations. int is used when you need integers. The problem in this exercise was the formulation of r. Now r is = 2/12, this means that when we type r as that, the computer assumes that it is an integer and treats it as such. So, it will convert the 0.166667 into 0. To overcome this, all you have to do is type 2.0 instead of 2 alone.

The %0.2 command restricts the float variable to 2 decimal places. By default, it has 6 decimal places.

I have used the function scanf_s instead of scanf simply because my compiler does not work with scanf.

One of the factors that influence the effectiveness of chemical sanitizer works effectively between 13° C and 49° C

12345 [234]

Answer:

temperature

Explanation:

Temperature is one of the three factors known to have remarkable influence on the effectiveness of chemical sanitizers. These sanitizers generally perform best at temperature range of 13 – 49 degrees centigrade.

Also, contact time is one of the factors that is needed for the sanitizers to effectively kill the microorganisms. The item to be cleaned should come in contact with the chemical for the recommended period of time.

Drag each label to the correct location. Each label can be used more than once. Match the device to the port through which it co

son4ous [18]

Answer:

Mouse - USB

Monitor - display port, HDMI, and thunderbolt port

External hard drive - USB and thunderbolt port

Flash drive - USB

Explanation:

A computer mouse is an input device used to interact with a computer system. It connects with the computer through the USB port.

A Monitor is an output device that is used to display information on a computer system. It can be connected to the system through the display ports, HDMI, and the thunder port.

The External hard drive is a storage device that holds data for a long period of time. It has adapters to connect to the computer through the USB ports or thunderbolt ports. The flash drive is similar in function to the hard drive but small in size and storage space. It only connects with the computer through USB ports.

Define the following terms: data model, database schema, database state, internal schema, conceptual schema, external schema, da

PolarNik [594]

Answer:

Following are the solution to the given terms:

Explanation:

Data Model: A set of concepts that are ideal for describing the layout, computational tools, relations, semantics, constraints on accuracy.

Database Scheme: It is also known as the overall design of the database.

Database State: It is the data in the database at a particular moment in time.

Internal Schema: The physical structure of the database is defined.

Conceptual Schema: It hides the details of physical storage.

External Schema: It describes the part of the database the user group sees. In other words, we can say that it is a view of the database.

Data Independence: The ability to modify the schema at a single level while modifying the schema at a higher level is often recognized.

DDL: It stands for the Data Definition Language, which is used by DBA and dev use for creating With particular scheme.

DML: It refers to the Data Manipulation Language, which is used to manipulate, add, recover, insert, remove, and alter data.

SDL: It stands for the storage definition language, in which the internal schema of the database is applied for storage description.

VDL: The view definition language specifies the user to view and mapping their conceptual schema.

Query Language: It is just an independent, dynamic, high-level dialect used during manipulation.

Host Language: It is also the machine language, that would be incorporated into the general programming language by low-level data handling commands.

Data sublanguage: It uses for embedding in the last language.

Database Utility: It is a program, which helps to handle the database with DBA's modules.

Catalog: The entire structure and constraints of the database is defined.

client/server architecture: The design of the database server system that device usability: model user, model server (landless storage) software Government computer design in which many users (remote processors) demand a central server to receive service (host computer).

Three-tier architecture: It is the application, data, user interface.

n-tier architecture: multiple levels. The nth level must only be able to handle the n+1 application and transmit it to the n-1 point.
