Answer:

This is false.

Explanation:

SATA drives do not have jumpers, because they don't use the master/slave feature. They are connected to the motherboard, and they are ready to work.

The master/slave feature was used by IDE hard drives.15 years ago, most motherboards didn't have too many IDE slots to place more than 1 or 2 HDDs, the IDE cable allowed you to connect 2 drives to 1 cable, greatly increasing your computer's storage space.

It was recommended to set as master the drive connected directly to the motherboard, and the other one as slave.

What is the process of adding random characters at the beginning or end of a password to generate a completely different hash ca
weeeeeb [17]

Answer:

Salting

Explanation:

Salting is an idea that is related to hashing of password which is the mapping of input data to a fixed length output data by the use of algorithms.

Salting is the addition of a distinctive value to the beginning or end of a password in order to form a different hash value from the hash value that would have been generated without the 'salt', thereby making the passwords more secure from attacks

The salt for each user is a unique value that is stored along with the username in a database

A store trying to analyze the behavior of its customers will often maintaina two-dimensional array A, where the rows correspond
marusya05 [52]

Answer:

See explaination

Explanation:

Diverse Subset Problem is NP: When presented with a set of k customers, it can be checked in polynomial time that you wont at any time have two customers in the set have ever bought the same product.

Independent Set is known to be NP-complete.

Independent Set ?P Diverse Subset Problem: Suppose we have a black box for Diverse Subset Problem and want to solve an instance of Independent Set. For our Independent Set Problem, we have a graph G=(V,E) and a number k, and need to find out if G contains an independent set of size (at least) k. We need to reduce the Independent Set Problem to a Diverse Subset Problem. We do this by constructing an array where each v in V is a customer and each e in E is a product, and customer v purchased every product e for which the product edge e touches the customer node v. Then we ask the black box for the Diverse Subset Problem if there is a subset of k customers that is diverse.

The black box for the Diverse Subset Problem will return.

¿Cómo es la onda percibida por un osciloscopio cuando hablamos de sonido? ¿Qué parámetros podemos observar en ella?
frozen [14]

Answer:

Las ondas de sonido, que es una onda longitudinal, son producidas por la vibración de un objeto de tal manera que (la onda de sonido requiere un medio de viaje, líquido sólido o gas) la dirección del sonido es la misma que la dirección de la vibración y como la el ancho de la vibración (hacia adelante y hacia atrás) aumenta, la amplitud de la vibración aumenta y el sonido es más fuerte

Un micrófono conectado al osciloscopio recoge el medio de aire vibrante de la onda de sonido de la energía de la onda de sonido y lo convierte (produce) señales eléctricas y electrónicas. El osciloscopio, que está diseñado para mostrar señales electrónicas, muestra las señales electrónicas transmitidas por el micrófono en la pantalla con los mismos valores de amplitud y frecuencia que el volumen y el tono de la onda de sonido, respectivamente.

Las características observables son;

1) El volumen o el volumen de la onda de sonido que se muestra como la amplitud) en el cátodo, con una amplitud más alta que representa un sonido más fuerte

2) El tono de la onda de sonido se muestra como el espaciado de onda en el osciloscopio, el sonido de tono más alto se muestra por las ondas que se acercan en la pantalla
