Axel is finally documenting his work. What could he be writing?

Consider the following two code segments, which are both intended to determine the longest of the three strings "pea", "pear", a

Nikolay [14]

Answer:

e) Code segment II produces correct output for all values of str, but code segment I produces correct output only for values of str that contain "pea" but not "pear".

Explanation:

if - elseif - else statements work in sequence in which they are written.

In case if() statement is true, else if() and else statements will not get executed.
In case else if() statement is true, conditions in if() and else if() will be checked and else statement will not be executed.
In case if() and else if() both are false, else statement will be executed.

First, let us consider code segment I.

In this, first of all "pea" is checked in if() statement which will look for "pea" only in the String str. So, even if "pearl" or "pear" or "pea" is present in 'str' the result will be true and "pea" will get printed always.

After that there are else if() and else statements which will not get executed because if() statement was already true. As a result else if() and else statements will be skipped.

Now, let us consider code segment II.

In this, "pearl" is checked in if() condition, so it will result in desired output.

Executable code is attached hereby.

Correct option is (e).

Develop an sec (single error correction) code for a 16-bit data word. generate the code for the data word 0101000000111001. show

Kipish [7]

Answer:

code = 010100000001101000101

Explanation:

Steps:

The inequality yields $2^{k} - 1 > = M+K$ , where M = 16. Therefore,

The second step will be to arrange the data bits and check the bits. This will be as follows:

Bit position number Check bits Data Bits

21 10101

20 10100

The bits are checked up to bit position 1

Thus, the code is 010100000001101000101

A computer has 4 GB of RAM of which the operating system occupies 512 MB. The processes are all 256 MB (for simplicity) and have

Afina-wow [57]

Answer:

$1-p^{14} = 0.99$

$p^{14}= 0.01$

$p =(0.01)^{1/14}= 0.720$

So then the value of the maximum I/O wait that can be tolerated is 0.720 or 72 %

Explanation:

Previous concepts

Input/output operations per second (IOPS, pronounced eye-ops) "is an input/output performance measurement used to characterize computer storage devices like hard disk drives (HDD)"

Solution to the problem

For this case since we have 4GB, but 512 MB are destinated to the operating system, we can begin finding the available RAM like this:

Available = 4096 MB - 512 MB = 3584 MB

Now we can find the maximum simultaneous process than can use with this:

$\frac{3584 MB}{256 MB/proc}= 14 processes$

And then we can find the maximum wait I/O that can be tolerated with the following formula:

$1- p^{14}= rate$

The expeonent for p = 14 since we got 14 simultaneous processes, and the rate for this case would be 99% or 0.99, if we solve for p we got:

$1-p^{14} = 0.99$

$p^{14}= 0.01$

$p =(0.01)^{1/14}= 0.720$

So then the value of the maximum I/O wait that can be tolerated is 0.720 or 72 %

Initialize the list short_names with strings 'Gus', 'Bob', and 'Zoe'. Sample output for the given program:

ohaa [14]

Answer:

Following are the correct code to this question:

short_names=['Gus','Bob','Zoe']#defining a list short_names that holds string value

print (short_names[0])#print list first element value

print (short_names[1])#print list second element value

print (short_names[2])#print list third element value

Output:

Gus

Bob

Zoe

Explanation:

In the above python program code, a list "short_names" list is declared, that holds three variable that is "Gus, Bob, and Zoe".
In the next step, the print method is used that prints list element value.
In this program, we use the list, which is similar to an array, and both elements index value starting from the 0, that's why in this code we print "0,1, and 2" element value.

Which of the following corresponds to the computer interface technology that uses icon, etc?

Aleksandr [31]

Answer:

D) GUI

Explanation:

GUI an acronym for Graphical user interface, is a type of user interface where a user interacts with a computer or an electronic device through the use of graphics. These graphics include icons, images, navigation bars etc.

GUIs use a combination of technologies and devices to create a layout that users can interact with and perform tasks on. This makes it easier for users who do have basic computer skills to utilize.

The most common combination of these elements is the windows, icons, menus and pointer paradigm (WIMP) . GUIs are used in mobile devices, gaming devices, smartphones, MP3 players etc.
