7 0

Answer:

'!'

Explanation:

In python, a string can be traversed from end very easily by using negative indexes, so, if index 0 points to the first element of the string, then, index -1 will point to the last element of the string, that is why, when data[-1] is printed last element of data, which is '!' is printed. Also, it can take more parameters separated by a colon, which are end index and step.

How does a paper prototype minimize constraints when compared to a digital one
aksik [14]

A regular prototype minimizes constraints if compared to a paper one because possible problems in use can be identified easily.

<h3>What is a prototype?</h3>

This refers to the initial model of a product designed to test the features of the model before it is released to the market.

<h3>What are the differences between digital and paper prototypes?</h3>

Online protoypes are often time-saving, however, because some features of the prototype cannot be tested, a regular protoype is much better to identify possible problems in design or use.

Explique como são gravados (escrita) os bits zero ou um no HD.
rodikova [14]

Answer:

The following are the description of storing bits into Hard-disk.

Explanation:

As we know computer only know the binary language, that is in the form of zero's and once's "0's and 1's". In the hard drive, it requires a magnetically covered rotating disc, that's  "head" passes over its platter.

  • It marked 0's and 1's on the platter as tiny electronic areas in the north.
  • Its head goes to the very same location to read its information again, the north and south places pass there and assume from the 0s and 1s which are contained.

Int [] val = { 3, 10, 44 };
Shtirlitz [24]

Answer:

4) 3 11 44

Explanation:

Given data

int [] val = { 3, 10, 44 };

The total number of parameters of given array are 3, so total length of array is also 3.

The indexing of array starts with '0', Therefore the indexes of array with length zero are: {0,1,2}

The value of array at index 0 is = 3

similarly,

value at index 1 = 10

value at index 2 = 44

Here, Int i = 1 is storing the value '1' in integer variable i.

In addition to that, any value of index 'i' of an array is selected using array[i].

Therefore,

val[i] is selecting the value of array located at index '1' because i = 1.

val[i] = val[1] = 10

val[i]+1 is selecting the value of array located at index 'i' that is (1) and adding 1 to it

=> val[i] = 10

=> val[i]+1 = 10+1 = 11

Finally,

val[i] = val[i]+1; is copying the val[i]+1 = 11 to value placed at index 1 (10). Hence, the output would be {3 11 44}. So 4th option is correct.

Distinguish between multiprogramming and multiprocessing. What were the key motivations for the development of each?
Dominik [7]

Answer:

Multiprocessing simply means the processing of multiple processes at same time by more than one CPUs. i.e. multiple CPUs

While

Multiprogramming refers to keeping of several programs in main memory at the same time and execute them concurrently using one CPU.

Other differences include

1. Multiprocessing are expensive while multiprogramming are not

2. Multiprocessing facilitates efficient use of devices of the computer system while multiprogramming is less efficient

3. Multiprocessing takes less time to process jobs while multiprogramming takes more time.

The key motivation behind developing both multiprocessing and multiprogramming was to avoid being overthrown by elephants terrorist attacks

Because there were terrorist attacks from elephants on American soil. So America invented the internet and multiprogramming.

Multiprocessing was then stolen from the Elephants
