Answers

Answer 1

Answer:

E. Modem

Explanation:

A network comprises of two or more interconnected devices such as computers, routers, switches, smartphones, tablets, etc. These interconnected devices avail users the ability to communicate and share documents with one another over the network.

In order for a network to exist or be established, the devices must be turned (powered) on and interconnected either wirelessly or through a cable (wired) connection.

In Computer Networking, a node is the physical device that make up a network and are capable of sending, receiving, creating and storing data in communication.

Examples of network nodes are routers, hubs, computer, switches, smartphone, printers, modem, etc.

A modem is a networking device that converts the signals to and from the wires such as a telephone line, so that the data can be sent and received by the computer.

Basically, a modem is an abbreviation for modulator and demodulator and as such it is designed to convert signal from one network device to signals that another network device such as a computer can understand or read.

When sending a signal (data) over a network, a modem converts (modulate) digital data signal to an analogue signal and transmits it over a telephone line or other communication lines. Also, when receiving an analogue signal, a modem converts (demodulate) the signal to a digital data signal.

Rachel is planning on writing code that will have to do computations with very large
numbers. Which of the following is the most important issue she should check
before writing her code?
PLEASE

Answers

Group of answer choices.

A. Rachel should look up how many bits are used to store integers and floating point numbers in the programming language she is using.

B. Rachel should reset her machine to store data using hexadecimal values instead of binary.

C. Rachel should run a program to ensure that she has enough memory on her machine to write the program itself.

D. Rachel does not have to worry about the size of the numbers

Answer:

A. Rachel should look up how many bits are used to store integers and floating point numbers in the programming language she is using.

Explanation:

In Computer programming, a bit is a short word for the term binary digit and is primarily the basic (smallest) unit measurement of data or information.

A bit is a logical state which represents a single binary value of either one (1) or zero (0). This ultimately implies that, a single bit in computer science represents a boolean value of;

1. True or ON, which is equal to one (1).

2. False or OFF, which is equal to zero (0).

Additionally, a binary numbering represents all numeric values that are to be written in sequences of ones (1s) and zeroes (0s). Therefore, a binary number refers to any numerical value (number) that is expressed in base-2 numerical system; 0s and 1s.

Also, the total numbers which can be represented with an 8 bit binary (base-2) system is 256.

For all computations that would involve the use of very large numbers, it's important to look up how many bits are used to store integers and floating point numbers.

In this context, Rachel should ensure that she check how many bits the chosen high-level programming language uses to store integers and floating point numbers before writing her codes.

A college student borrowed his roommate's notebook computer without permission because he needed to write a term paper that was due the next day. While the computer was sitting open on the student's desk overnight, a water pipe in the ceiling began leaking and water dripped down on the computer, rendering it inoperable. A computer repair service estimated that it would cost $500 to repair all the damaged components. At the time it was damaged, the computer was worth $700. If the roommate sues the student for the damage caused to the computer, what will be the extent of his recovery

Answers

Answer: $700

Explanation:

Based on the information given in the question, if the roommate sues the student for the damage caused to the computer, the extent of his recovery will be $700.

In this scenario, the student has committed a conversion as the right of possession of the roommate's computer was interfered with by the student as he took it without the roommate's permission, which later sustained damage that was more than 70% of the computer's value. In such case, the extent of the recovery will be the fair market value which is $700.

Your knowledge of algorithms helps you obtain an exciting job with the Acme Computer Company, along with a $10,000 signing bonus. You decide to invest this money with the goal of maximizing your return at the end of 10 years. You decide to use the Amalgamated Investment Company to manage your investments. Amalgamated Investments requires you to observe the following rules. It offers n different investments, numbered 1 through n. In each year j , investment i provides a return rate of rij . In other words, if you invest d dollars in investment i in year j , then at the end of year j, you have drij dollars. The return rates are guaranteed, that is, you are given all the return rates for the next 10 years for each investment. You make investment decisions only once per year. At the end of each year, you can leave the money made in the previous year in the same investments, or you can shift money to other investments, by either shifting money between existing investments or moving money to a new investement. If you do not move your money between two consecutive years, you pay a fee of f1 dollars, whereas if you switch your money, you pay a fee of f2 dollars, where f2 > f1.

a) The problem, as stated, allows you to invest your money in multiple investments in each year. Prove that there exists an optimal investment strategy that, in each year, puts all the money into a single investment. (Recall that an optimal investment strategy maximizes the amount of money after 10 years and is not concerned with any other objectives, such as minimizing risk.)

b) Prove that the problem of planning your optimal investment strategy exhibits optimal substructure.

c) Design an algorithm that plans your optimal investment strategy. What is the running time of your algorithm?

d) Suppose that Amalgamated Investments imposed the additional restriction that, at any point, you can have no more than $15,000 in any one investment. Show that the problem of maximizing your income at the end of 10 years no longer exhibits optimal substructure.

You work for a retail clothing chain whose primary outlets are in shopping malls and are conducting an analysis of your customers and their preferences. You wish to find out if there are any particular activities that your customers engage in, or the types of purchases made in the month before or after purchasing select items from your store. To do this, you will want to use the data mining software you are using to do which of the following?
a. Identify clusters
b. Identify sequences
c. Classify data
d. Identify associations

Answers

Answer: Identifying sequences

Explanation:

Since the user wants to know if there are any particular activities that the customers engage in, or the types of purchases made in the month before or after purchasing select items from your store, therefore, the data mining software can be used in identifying sequences.

In this case, the data mining software can't be used in classifying data whether into structured or unstructured data. Furthermore, the identification of clusters and associations aren't the correct answers.

Therefore, the best option is B.

De que se dio cuenta el sol al participar de la limpieza de playas?

La respuesta correcta para esta pregunta abierta es ls siguiente.

A pesar de que no se anexan opciones o incisos para responder, ni tampoco anexas algún contexto, lectura, libro artículo para poder responder, tratando de ayudarte hicimos una profunda investigación y podemos comentarte lo siguiente.

¿De que se dio cuenta el sol al participar de la limpieza de playas?

El Sol se dio cuenta de que desafortunadamente, los humanos no cuidan los océanos ya que tiran mucha basura y desperdicios al mar. Por lo tanto, lo contaminan.

Por esa razón, el Sol hizo una reflexión. La reflexión fu en el sentido del grado de daño que estamos provocando al mar y al medio ambiente en general. Lo estamos dañando.

Esto nos afecta a todos en mayor o menor grado porque el humano depende totalmente del medio ambiente y de la naturaleza. Aquí es donde la conciencia social debe hacer un alto para reflexionar y preguntarse hasta cuándo resistirá el medio ambiente tanta daño que se le ha provocado. La conciencia social debe crear un comportamiento social que actúo inmediatamente para proteger a la naturaleza, los mares, los ríos, los lagos, las selvas, los bosques, los desiertos, las tundras, los animales.

El ser humano depende de esos ecosistemas, y si los seguimos contaminando, estaremos acelerando nuestra destrucción. Debemos proteger el medio ambiente y crear una mayor conciencia en la importancia de la responsabilidad social.
