Answer:

Explanation:

You should make a string where they enter the vaulue and you calculate the interest by multipliying then the code should look like this input balance

balance=0 then they would select the amount and 0+entered amount times interest im 12 btw so

Who conceptualizes the design and the working of a website

Citrus2011 [14]

Answer is "Web Designer".

Web Designers are the "artists" of the website. They conceptualize the layout and functionality of the site, from features to format. They may do little coding, and are mostly involved in the creative elements of web design. The Web Developer is less big-picture, and more knitty-gritty building of the website. She is the one who does the coding and actually builds the website, using the web designer's model.

A combination lock has the following basic properties:

fomenos

Answer:

public class CombinationLock {

private int combinationNumber1 = 0;

private int combinationNumber2 = 0;

private int combinationNumber3 = 0;

CombinationLock(int combinationNumber1, int combinationNumber2, int combinationNumber3){

this.combinationNumber1 = combinationNumber1;

this.combinationNumber2 = combinationNumber2;

this.combinationNumber3 = combinationNumber3;

}

public boolean open(int number1, int number2, int number3){

if(number1 == combinationNumber1 && number2 == combinationNumber2 && number3 == combinationNumber3)

return true;

else

return false;

}

public boolean changeCombo(int number1, int number2, int number3, int newNumber1, int newNumber2, int newNumber3){

if (open(number1, number2, number3)){

combinationNumber1 = newNumber1;

combinationNumber2 = newNumber2;

combinationNumber3 = newNumber3;

return true;

}else

return false;

}

Explanation:

- Three variables are created to hold the combination.

- A constructor is created to set the combination.

- A boolean method called open is created to check if the given numbers are correct, and returns true (otherwise returns false).

- A boolean method method called changeCombo is created to check if given numbers are correct. If they are correct, it assigns new values for the combination and returns true (otherwise returns false).

You speak to a business owner that is taking in almost $2,000 in revenue each month. The owner still says that they’re having tr

Serga [27]

Let's say for example that the business is taking in $2000 of revenue. That is the amount that the business collected for it's services - like for fixing the computer. What if though it costs $500 for the equipment (that's an expense). Now they only made $1500. Now the customer complains and says that the computer isn't fixed properly so the company sends out a techie for 2 additional hours. They need to pay their employee (another expense). Now the $1500 is down to $1400. They would have utilities to keep their lights on and insurance and many other expenses.

Your profit looks like this:
Profit = Revenue - Expenses

What is an 8086 microprocessor used for

Liula [17]

A sixteen bit microprocessor chip used in early IBM PCs. The Intel 8088 was a version with an eight-bit externaldata bus.

The Intel 8086 was based on the design of the Intel 8080 and Intel 8085 (it was source compatible with the 8080)with a similar register set, but was expanded to 16 bits. The Bus Interface Unit fed the instruction stream to theExecution Unit through a 6 byte prefetch queue, so fetch and execution were concurrent - a primitive form ofpipelining (8086 instructions varied from 1 to 4 bytes).

It featured four 16-bit general registers, which could also be accessed as eight 8-bit registers, and four 16-bit indexregisters (including the stack pointer). The data registers were often used implicitly by instructions, complicatingregister allocation for temporary values. It featured 64K 8-bit I/O (or 32K 16 bit) ports and fixed vectored interrupts.There were also four segment registers that could be set from index registers.

The segment registers allowed the CPU to access 1 meg of memory in an odd way. Rather than just supplyingmissing bytes, as most segmented processors, the 8086 actually shifted the segment registers left 4 bits and addedit to the address. As a result, segments overlapped, and it was possible to have two pointers with the same valuepoint to two different memory locations, or two pointers with different values pointing to the same location. Mostpeople consider this a brain damaged design.

Although this was largely acceptable for assembly language, where control of the segments was complete (it couldeven be useful then), in higher level languages it caused constant confusion (e.g. near/far pointers). Even worse, thismade expanding the address space to more than 1 meg difficult. A later version, the Intel 80386, expanded thedesign to 32 bits, and "fixed" the segmentation, but required extra modes (suppressing the new features) forcompatibility, and retains the awkward architecture. In fact, with the right assembler, code written for the 8008 canstill be run on the most recent Intel 486.

The Intel 80386 added new op codes in a kludgy fashion similar to the Zilog Z80 and Zilog Z280. The Intel 486added full pipelines, and clock doubling (like the Zilog Z280).

So why did IBM chose the 8086 series when most of the alternatives were so much better? Apparently IBM's own engineers wanted to use the Motorola 68000, and it was used later in the forgotten IBM Instruments 9000 Laboratory Computer, but IBM already had rights to manufacture the 8086, in exchange for giving Intel the rights to its bubble memory designs. Apparently IBM was using 8086s in the IBM Displaywriter word processor.

Other factors were the 8-bit Intel 8088 version, which could use existing Intel 8085-type components, and allowed the computer to be based on a modified 8085 design. 68000 components were not widely available, though it could useMotorola 6800 components to an extent.

Hope this helps
