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.

write full information about first computer virus ?
Answer:
A computer virus is a man made program just like other program.it is a harmful program developed intentionally to distrub the normal functioning of a computer.It can destroy data,information and other useful programs of the computer.As the result you will not get data,information and other useful progarams to use.when it destroy operating system software of a computer.
Answer:
The "Creeper system," the first computer virus, was an experimental self-replicating virus released in 1971. It was filling up the hard disk to the point that a computer could no longer function. BBN technology in the United States produced this virus. When the Creeper virus infects a computer, it causes it to output a file. It will then cease to function while it searches for another TENEX system. It creates a connection with the machine in question, and so on. Its last payload or impact when it's finished with a system is to display its message.

A government agency is getting rid of older workstations. The agency will donate these workstations, along with other excess computer systems, to nearby schools. Management reminds the systems administrators about the data sanitization and disposal policy. What policy items are applicable for these IT systems, prior to donating to the schools
The "DoD Standard" is a term used during the data sanitizing industry and refers to DoD 5220.22-M, and the further discussion can be defined as follows:
The simplest ways are being used to help eliminate the previously stored data, by deleting hard disc storage facilities with the same data wherever that used a sequence of all zeros.The sparging eliminates statistics to entirely delete the gravitational flux from electronic media. Hard drives as well as other data storage devices, for example, computer tapes, retain magnetic data. It could no longer be seen as storage after a disk is degaussed.Therefore, the final answer is "Using the DoD 5220.22-M method and Degauss media with a magnet".

Assume the existence of a Building class. Define a derived class, ApartmentBuilding that contains four (4) data members: an integer named numFloors, an integer named unitsPerFloor, a boolean named hasElevator, and a boolean named hasCentralAir. There is a constructor containing parameters for the initialization of the above variables (in the same order as they appear above). There are also two function: the first, getTotalUnits, accepts no parameters and returns the total number of units in the building; the second, isLuxuryBuilding accepts no parameters and returns true if the building has central air, an elevator and 2 or less units per floor.
Answer:
Explanation:
The following code is written in Java. The class ApartmentBuilding extends the assumed class of Building but does not call any of its methods since we do not have access to it. The ApartmentBuilding class contains all of the variables listed, as well as constructor and methods, including getter and setter methods for each variable. A test case for the class is provided in the image below with it's output.
class ApartmentBuilding extends Building {
int numFloors, unitsPerFloor;

Draw a circuit with a 12-volt battery, a 100 ohms resistor in series, and two resistors (each of value 200 ohms) in parallel. What is the total resistance of the circuit?
Answer:
200 Ω
Explanation:
Hi there!
Please see below for the circuit diagram.
1) Find the total resistance of the resistors in parallel
Total resistance in parallel equation: [tex]\frac{1}{R_T} = \frac{1}{R_1} +\frac{1}{R_2}[/tex]
Both the resistors measure 200 Ω. Plug these into the equation as R₁ and R₂:
[tex]\frac{1}{R_T} = \frac{1}{200} +\frac{1}{200}\\\frac{1}{R_T} = \frac{1}{100}\\R_T=100[/tex]
Therefore, the total resistance of the resistors in parallel is 100 Ω.
2) Find the total resistance of the circuit
Now, to find the total resistance of the circuit, we must add the 100 Ω we just solved for and the 100 Ω for the other resistor placed in series:
100 Ω + 100 Ω = 200 Ω
Therefore, the total resistance of the circuit is 200 Ω.

Answer:
DMT — or N, N-dimethyltryptamine in medical talk — is a hallucinogenic tryptamine drug. Sometimes referred to as Dimitri, this drug produces effects similar to those of psychedelics, like LSD and magic mushrooms. Other names for it include: fantasia.
Explanation:
Answer:
DMT, abbreviation of Dimethyltryptamine, powerful, naturally occurring hallucinogenic compound structurally related to the drug LSD (lysergic acid diethylamide). DMT blocks the action of serotonin (a transmitter of nerve impulses) in brain tissue. It is inactive when taken by mouth and produces effects only when injected, sniffed, or smoked. The hallucinatory action
Explanation:
Major plant genera containing DMT include Phalaris, Delosperma, Acacia, Desmodium, Mimosa, Virola, and Psychotria, but DMT has been found even in apparently innocuous sources, such as leaves of citrus plants (Servillo et al., 2012), and in the leaves, seeds, and inner bark of mimosa tenuiflora

cual es el procedimientos para asistir en el transporte publico a personas discapacitadas
Answer:
Una discapacidad física o motora en una o más partes del cuerpo obstaculiza las acciones y / o movimientos de la persona con discapacidad. La discapacidad puede surgir porque las partes del cuerpo no han crecido completamente o están dañadas (anomalías físicas) o porque las funciones físicas están alteradas (anomalías funcionales).
En la mayoría de los casos, se proporciona una ayuda a las personas con discapacidades físicas graves para que puedan desenvolverse más fácilmente en la sociedad. Alguien con una discapacidad motora severa en las piernas a menudo usa una silla de ruedas. Las personas con una discapacidad motora de las manos (pérdida de la motricidad fina) o de los brazos pueden compensar esto con un manipulador o ayudas especializadas en tareas, como un dispositivo para comer o un dispositivo para girar las hojas.
Así, todos estos elementos deben ser posibles de ser insertados en los medios de transporte público como forma de ayudar a estas personas a trasladarse por estos medios, es decir, los autobuses, trenes, etc., deben estar adaptados para poder recibir allí a pasajeros en sillas de ruedas o con necesidades motoras especiales.

What should you do if your engine stalls while you are driving?
A: Hold your steering wheel tightly(power steering is difficult)
B: Shift your transmission to neutral
C: Try to re-start; if unable, stop off road, using four-way flashers
D: All of the above
Answer:
D
Explanation:
All of the above should you do if your engine stalls while you are driving. Thus option D is correct.
What is driving?Driving, which includes operating and moving a vehicle in a controlled manner, includes using a car, scooter, truck, vehicle, or scooter. Drivers must abide by the local highway and traffic rules in order to be allowed to drive on city roads, which is contingent upon a number of requirements being completed.
In most situations, you'll lose auto steering whenever the engine shuts off, making it challenging to spin the wheel, as well as power brakes will shortly follow.
Although it takes significantly more pressure, you could still steer but instead, stop. Put the gearshift in neutral. If you can't restart, stop off the road and use your 4 blinkers. Therefore, option D is the correct option.

What is binary number system? Why is it used in computer system?
Answer:
Computers depend mainly on binary because it’s more time efficient for them to so.
Explanation:
It’s easier to identify 0 as “off” and 1 as “on”. As you may know, transistors are the fundamental blocks of microprocessors and ICs. The reasons this is the case is that these transistors form logic gates which can carry out basic logic operations. These logic gates are a huge step into making microprocessors/ICs/etc. And what do these logic gates depend on? They depend on binary.
Whoa whoa, wait a minute. Let’s first take a step back to know a thing or two about logic gates.
These logic gate can be constructed from transistors. They carry basic logic operations. You have one or more inputs “entering” the logic gate ——-> A certain operation is performed on them ——-> you get your output. The input is a voltage. This voltage it can be interpreted as an “on” or “off” according to the gate. Once again these offs and ons are 0s and 1s. For example the Inverter/NOT gate is a gate that simply takes an input and gives its inverse. For example:-
A low voltage/an “off” signal/ a “0” “enters” the NOT gate. ——-> A high voltage/an “on” signal/ a “1” is the result of the operation performed
(In the above example low voltage = “off” signal = 0, high voltage = “on” signal = 1)
As you can see, a 0 enters the NOT gate and a 1 comes out or vice versa. Now, if you were a logic gate, you’d prefer working with just 0s and 1s right? I would. This would be much easier to work with than a lot of different values.
It’s a herculean task to work with these though as a human. And fortunately, programming languages exist for giving the computer instructions to do in a “language” other than its own.
