Answer:
213
Explanation:
The given parameters are;
The network on which the host is on = 192.168.146.0
The subnet mast = 255.255.255.0
The binary value of the host portion = 11010101
To convert the binary value to decimal value, we proceed by multiplying each of the digits of the binary value by the corresponding power of 2, from the left to right, starting from a power of 0, and sum the result, as follows;
(11010101)₂ = (1×2⁷ + 1×2⁶ + 0×2⁵ + 1×2⁴ + 0×2³ + 1×2² + 0×2¹ + 1×2⁰)₁₀
1×2⁷+1×2⁶+0×2⁵+1×2⁴+0×2³+1×2²+0×2¹+1×2⁰= 128+64+0+16+4+1 = 213
∴ (11010101)₂ = (213)₁₀
The decimal value of 11010101 is 213.

1.Explain what service is offered over an ISDN BRI circuit to the residential telephone subscriber.2.How many voice channels are available on one ISDN BRI circuit?3.Can an ISDN line carry data information along with voice information simultaneously? If yes at what bit per second rate is available for the data transmission?4.When commercial power is lost at the resident’s home the ISDN line continues to function. A. True B. False
Answer:
Following are the solution to the given points:
Explanation:
For point 1:
Integrated Communications Networks is a technology used to transmit digital signals using telephone lines cables over a local loop.
Due to its larger capacity, it's far faster than just a 's got. ISDN Basic Rate Service (BRI) offers a total bandwidth of 144 kpbs, which would be based on two B channels and a 16 Kbps D channel. As private and small company customers, however, it is adequate.
The BRI is split into two categories: a) in-house cable from the ISDN end to the NT (S/T reference or S-bus) and b) broadcast from the NT to a headquarter (U reference point).
It enables a full-duplex operating point.
This BRI section's maximum length is between 4 to 8 km.
You pay for the speed you utilize using an ask service. In all other words, the price cost of how long you remain connected was evaluated. One can also buy flat-rate usage plans because you can with the phone service.
Given the fact ISDN uses an existing Cat 3 cable, re-connection to a service is not necessary.
In regions in which no additional high-speed access to the internet is available, ISDN can be available.
For point 2:
In the BRI configuration, 2 Data (bearer) lines with 64 kbit/s are available. With voice and user information the B-channels have been used.
For point 3:
Yes, It offers concurrent voice & data communications with improved signaling capacity at 64 kb/s.
For point 4:
It is true.

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.

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;
boolean hasElevator, hasCentralAir;
public ApartmentBuilding(int numFloors, int unitsPerFloor, boolean hasElevator, boolean hasCentralAir) {
this.numFloors = numFloors;
this.unitsPerFloor = unitsPerFloor;
this.hasElevator = hasElevator;
this.hasCentralAir = hasCentralAir;
}
public int getTotalUnits() {
int total = this.numFloors * this.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.
I hope this helps!

API is application programming interface. APIs allow communication between applications/programs: they are basically "outside" data that can be accessed by an application by using it's code(example, how I may access go*gle fonts using it's API attached to my html stylesheet link).
The source is the code itself. Source code is the set of instructions that makes any program or application do whatever they do. An API is defined and works based on its source code.
Answer:
Methods
Explanation:
Methods, also called functions, are snippets of code that are meant to answer a specific question or perform a specific task. They will sometimes take parameters as input to provide more context for the question being asked, or task being performed.

Use methods for entering the values, performing the computations, and displaying the results. Results should be formatted with one position to the right of the decimal and printed number aligned in a tabular display.
Answer:
Explanation:
This code is written in Java. It creates a Rectangle class that contains variables for the height and width. It also contains constructor, methods for calculating perimeter and area, and a printInfo method to print out all the results. A test case has been created in the main method which creates a Rectangle object and prints out the printInfo which calls the area and perimeter methods as well. The output can be seen in the attached image below. Due to technical difficulties I have added the code as a txt file below.
List the difference between GIGO and bug
Answer:
A bug happens when a tool does not do what it should do. For example, the famous Y2K bug had the potential of showing the wrong time. GIGO, which stands for Garbage In Garbage Out, is a different situation in which the tool performs what it should do but it is applied in a place that does not make sense.
Explanation:
When test engineer find any error in the application they called it as bug. Bug is informal name to Defect which is flaws or misatkes in the Code or Design. Error is any mistake done by the user while using the Apllication or Software. Failure due to any error or defect if the software will not work properly .

What is the difference between system software and operating system with examples each
Answer:
OS is an example of System Software.
Let me clarify at a basic level, For an application to work on a system , It needs
Embedded Software (codes Dumped inside hardware)
System Software
Application Software (Obviously as that is what you see on screen and work with)
The work users wish to do with the system is done by the processor/CPU.
But, Processors know only machine language instructions.
System software is the one which gets to know what the user wants to do from the Application software and conveys,manages the processor/other hardware of what needs to be done.
There are numerous examples of System Software each having functions of its own. It can be BIOS,Assembler,Compilers,kernel,other utilities.

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.
