Answer:

a. True

Explanation:

A computer can be defined as an electronic device that is capable of receiving of data in its raw form as input and processes these data into information that could be used by an end user. Computers can be classified on the basis of their size and capacity as follows;

I. Supercomputers.

II. Mainframe computers.

III. Mini computers.

IV. Micro computers.

Mainframe computers were developed and introduced in the early 1950s.

Mainframe computers are specifically designed to be used for performing multi-programming because they are high-performance computers with the ability to handle multiple users. As a result, it simply means that mainframe computers can be used to effectively and efficiently perform the work of over one hundred (100) users at a time on the computer. Some examples of mainframe computers include the following; IBM Es000 series, CDC 6600 and ICL39 Series.

Furthermore, mainframe computers are mostly or commonly used by large companies, business firms or governmental institutions for performing various complex tasks such as census, financial transactions, e-commerce, data sequencing, enterprise resource planning, etc.

Consider the following recursive method, which is intended to return a String with any consecutive duplicate characters removed.
saul85 [17]

Answer:

D. return str.substring(0, 1) + removeDupChars(str.substring(1));

Explanation:

The logic here is following:

If the there are consecutive duplicate characters, return the removeDupChars method. The parameter of the removeDupChars method is a string, but the duplicate of the first character is removed from the string. The else-if part of the program does this job.

If the consecutive characters are not duplicated, return the first character of the string and the removeDupChars method. The parameter of the removeDupChars method is the rest of the string characters. The else part of the program does this job.

When the length of the str becomes one (or when the str is null), the program reaches its base and returns the str. The if part of the program does this job.

3.8 LAB: Read values into a list
Salsk061 [2.6K]

An example of Read values into a list is:

#!/usr/bin/python

list1 = ['math', 'chemistry', 1995, 2001];

list2 = [1, 2, 3, 4, 5, 6, 7 ];

print "list1[0]: ", list1[0]

print "list2[1:5]: ", list2[1:5]

<h3>What is Python Lists?</h3>

This is known to be a list that is seen as the a most versatile in terms of datatype that are known to be available in Python.

It is one that can be written as a list of comma-separated values that is found in between square brackets.

Note that the most Important thing about a list is that all the items in a list are ones that do not require to be of the same type.

Hence Creating a list is very simple to do and it is done by putting a lot of comma-separated values in between square brackets.

Therefore, An example of Read values into a list is:

#!/usr/bin/python

list1 = ['math', 'chemistry', 1995, 2001];

list2 = [1, 2, 3, 4, 5, 6, 7 ];

print "list1[0]: ", list1[0]

print "list2[1:5]: ", list2[1:5]

A detective agency is looking to bust an arms sale. According to available intelligence, the sale is likely to happen in one of
Paha777 [63]

Answer:

Probability Distribution={(A, 4/7), (B, 2/7), (C, 1/7)}

H(X)=5.4224 bits per symb

H(X|Y="not C")=0.54902 bits per symb

Explanation:

P(B)=2P(C)

P(A)=2P(B)

But

P(A)+P(B)+P(C)=1

4P(C)+2P(C)+P(C)=1

P(C)=1/7

Then

P(A)=4/7

P(B)=2/7

Probability Distribution={(A, 4/7), (B, 2/7), (C, 1/7)}

iii

If X={A,B,C}

and P(Xi)={4/7,2/7,1/7}

where  Id =logarithm to base  2

Entropy, H(X)=-{P(A) Id P(A) +P(B) Id P(B) + P(C) Id P(C)}

=-{(1/7)Id1/7 +(2/7)Id(2/7) +(4/7)Id(4/7)}

=5.4224 bits  per symb

if P(C)  =0

P(A)=2P(B)

P(B)=1/3

P(A)=2/3

H(X|Y="not C")= -(1/3)Id(I/3) -(2/3)Id(2/3)

=0.54902 bits per symb
