1 answer:

8 0

The components of a computer that hold a dangerous amount of energy even when it's unplugged are capacitors, and inductor.

<h3>What is electricity?</h3>

Electricity is the flow of charges in a closed system. Electricity is very important to run electronic devices, but electricity can damage the tissues of human body and cause heart attack if touch it with hands.

Thus, the components of a computer that hold a dangerous amount of energy even when it's unplugged are capacitors, and inductor.

Computer keyboard failures can be attributed to electrical defects or mechanical defects. a repair facility currently has 25 fai

Mariulka [41]

You are going to select 5 keyboards, from a set of 25 defective keyboards. When you select the first keyboard it may be have either electrical deffects or mechanical deffect, this is two possibilities. The same happens with the second, third, fourth and fifth selection. Then each selection has 2 different possibilities, and the number of possibilities are: 2*2*2*2*2 = 32.

But that is considering that the order matters. This is that it is different that the first has electrical deffects and the others have mechanical defects than the second has mechanical electrical deffects and the other has mechanical deffects.

If you the order is not relevant, then the only different outcomes are:

1) 5 with electrical deffects
2) 4 with electrical deffects and 1 with mechanical deffects
3) 3 with electrical deffects and 2 with mechanical deffects
4) 2 with electrical deffects and 3 with mechanical deffects
5) 1 with electrical deffects and 4 with mechanical deffects
5) 5 with mechanical deffects.

In this case the answer is 6 different ways.

Which of the following statements is true? A. Interpreted programs run faster than compiled programs. B. Compilers translate hig

alina1380 [7]

Answer:

Explanation:

Computer programs are written in high level languages. Every language has its own set of syntax and semantics.

Computer only understands instructions in machine language which is written using strings of 0 and 1.

Thus, for execution of a high level language program, it is mandatory to convert high level instructions into machine instructions.

This translation into machine language is done in two ways – compilation or interpretation.

Some languages are compiled while others are interpreted.

Both compilers and interpreters are programs and process the high level language program as needed.

Compiler

Any program written in high level language is compiled.

The program is first analyzed before compilation. This process takes time. The analysis phase is called pre processing.

The program compilation stops only when the program is completely analyzed. Hence, it is difficult to locate the error in the program. This makes debugging easy.

Debugging is defined as removal of errors in the programs.

A compiler is responsible for converting high level language code into machine level code.

The complete program undergoes compilation at the same time.

A compiled program executes faster than an interpreted program.

A compiled program produce machine code which is a collection of 0 and 1, hence, it takes less time to execute.

Examples of compiled languages are C and C++.

Interpreter

Some high level languages are interpreted.

The high level language code is translated into an intermediate level code. This intermediate code is then executed.

The analysis of the program takes less time and takes place before interpretation begins. The analysis phase is called pre processing.

An interpreted program is translated one line at a time.

The program interpretation stops when an error is encountered. This makes debugging easy.

Debugging is defined as removal of errors in the programs.

Examples of interpreted languages include Python and Ruby.
