Answer:

TRUE

Explanation:

Regardless of the complexity of the database, its development will follow 7 important steps:

1) Requirements analysis to develop database

2) Database Development Test Plan

3) Data modeling

4) Packet Encoding

5) Conducting internal and external tests to develop database

6) Integration and Implementation

7) Documentation

Convert the following numbers from decimal to binary, assuming unsigned binary representation:________.

kumpel [21]

Answer:

Binary representations of following are:

A) 35 = 100011

B) 3 = 11

C) 27 = 11011

D) 16 = 10000

Explanation:

The method to generate the binary number from a decimal is :

Keep on dividing the number by 2 and keep on tracking the remainder

And the quotient is again divided and remainder is tracked so that the number is completely divided.

And then write the binary digits from bottom to top.

Please have a look at the method in below examples:

A) 35

$\begin{center}\begin{tabular}{ c c c }Number & Quotient & Remainder\\ 2 & 35 & 1 \\ 2 & 17 & 1 \\ 2 & 8 & 0 \\ 2 & 4 & 0 \\ 2 & 2 & 0 \\ 2 & 1 & 1\end{tabular}\end{center}$

Writing the remainder from bottom to top.

So, binary number is 100011

B) 3

$\begin{center}\begin{tabular}{ c c c }Number & Quotient & Remainder\\ 2 & 3 & 1 \\ 2 & 1 & 1 \\ \end{tabular}\end{center}$

Writing the remainder from bottom to top.

So, binary equivalent is 11.

C) 27

$\begin{center}\begin{tabular}{ c c c }Number & Quotient & Remainder\\ 2 & 27 & 1 \\ 2 & 13 & 1 \\ 2 & 6 & 0 \\ 2 & 3 & 1 \\ 2 & 1 & 1 \end{tabular}\end{center}$

Writing the remainder from bottom to top.

So, binary equivalent is 11011.

D) 16

$\begin{center}\begin{tabular}{ c c c }Number & Quotient & Remainder\\ 2 & 16 & 0 \\ 2 & 8 & 0 \\ 2 & 4 & 0 \\ 2 & 2 & 0 \\ 2 & 1 & 1 \\\end{tabular}\end{center}$

Writing the remainder from bottom to top.

So, binary equivalent is 10000.

Answers are:

Binary representations of following are:

A) 35 = 100011

B) 3 = 11

C) 27 = 11011

D) 16 = 10000

Which component is most likely to allow physical and virtual machines to communicate with each other?

Diano4ka-milaya [45]

A component which is most likely to allow both physical and virtual machines to communicate with each other is a: virtual switch.

<h3>What is virtualization?</h3>

Virtualization can be defined as the creation of an abstract layer over computer hardware primarily through the use of a software, in order to enable the operating system (OS), storage device, server, etc., to be used by end users over the Internet.

In Cloud computing, some of the components (features) which is not required for a successful virtualization environment include the following:

Virtual machine

Host machine

Hypervisors

In conclusion, we can infer and logically deduce that a component which is most likely to allow both physical and virtual machines to communicate with each other is a virtual switch because it enables the virtual servers and the desktops to communicate.
