<h2>Answer:</h2>

Following are given answers to each part with explanation:

<h2>Explanation:</h2>

1. lt takes multiple clock cycles to access data from memory.

The statement is TRUE.

Accessing data from memory acquires two steps. In first step the address is read and in second step we go to the address in order to access the data.

2.Each byte of memory has a unique address.

The statement is TRUE.

Each byte in the memory attains a unique address therefore we can access the data residing at each byte specifically by giving address.

3.The total memory used by all running programs can never be larger than the computer's physical memory.

The statement is TRUE.

The running parts are always a sub part o a system so combining them all cannot exceed the total size of computer's physical memory.

4.The lower half (or least significant half) of the EBX register is called BX.

The statement is TRUE.

BX is he least significant or lower half of the register EBX (extended BX).

5.The following data locations are in order of fastest access time to slowest access time: cache, registers, main memory.

The statement is TRUE.

Yes the order of data locations from faster to lower is given correctly:

Cache is accessed faster than registers and in the end comes main memory.

6.The ALU performs only addition, subtraction, multiplication, and division operation:s

The statement is FALSE.

ALU is an abbreviation of Arithmetic Logic unit. So it performs arithmetical operations such as addition, subtraction, multiplication, and division as well as the Logical operations that are AND OR NOT XOR.

7. The control unit (CU) coordinates the sequencing of execution steps in an instruction cycle.

The statement is TRUE.

As obvious from the name Control unit (CU) has assigned the coordination of execution of steps in sequence.

8.The EIP register is updated when an instruction is fetched.

The statement is TRUE.

Whenever the user retrieve any instruction from EIP or fetch the instruction from it. EIP gets updated.

9.The step to fetch an operand is always necessary in the instruction cycle.

The statement is TRUE.

Most of the Instructions demand an operand in the instruction cycle so that they could be operated on. While some instruction not demand the operand such as Exit. But majority demands the operand so it is true.

10.In an instruction cycle, the operands are fetched before the instruction is fetched.

The statement is FALSE.

The first part of instruction cycle is to fetch the instruction, whereas the operands are fetched after it. So the statement get FALSE.

List and explain three ways study groups benefit your learning.

SashulF [63]

Answer:

Studying in groups can have many effective outcomes and be beneficial. Here are some ways studying in a group is benefical,

1. More support, limits chances of procrastination

<u> With many people, everyone is assigned a role or there is more determination by all peoples to get the work done than an individual being the only one responsible than many trying to accomplish the completion of the project. </u>

2. More people means more parts can get done effectively and taking notes is easier.

<u> More people allow the work (depending on the project of assignment) for the work to get more focused and worked on faster with the designated roles given. </u>

3. More interactive and allows (sometimes an enjoyable times) and to even learn faster than independently.

People, not all however, might like the company, there's support and even people skills is enhanced by being in the group.

This is for C++: Using a nested for loop output the following pattern to the screen:

olga55 [171]

Answer:

Following are the code to the given question:

#include <iostream>//header file

using namespace std;

int main()//main method

{

int r=26,x,y;//defining integer variable

char c;//defining a character variable

for(x= 1; y<= r; x++)//using for loop for count value

{

for(y= 1; y<= x; y++)//using for loop to convert value in triangle

{

c=(char)(y+64);//convert value into character

cout << c;//print character value

}

cout << "\n";//use print method for line break

}

return 0;

}

Output:

Please find the attachment file.

Explanation:

In this code, three integer variable "x,y, and r", and one character variable "c" is declared, that is used in the nested for loop, in the first for loop it counts the character value and in the next for loop, it converts the value into a triangle and uses the char variable to print its character value.

Which of the following is not a characteristic of Web 2.0?

Dmitry [639]

Answer:

c. mentorship programs taking place via the internet

Explanation:

The World Wide Web (WWW) was created by Tim Berners-Lee in 1990, which eventually gave rise to the development of Web 2.0 in 1999.

Web 2.0 can be defined as a collection of internet software programs or applications which avails the end users the ability or opportunity to share files and resources, as well as enhance collaboration over the internet.

Basically, it's an evolution from a static worldwide web to a dynamic web that enhanced social media. Some of the examples of social media platforms (web 2.0) are You-Tube, Flickr, Go-ogle maps, Go-ogle docs, Face-book, Twit-ter, Insta-gram etc.

Some of the main characteristics of Web 2.0 are;

I. Social networking.

II. Blogging.

III. Interactive comments being available on many websites.

Also, most software applications developed for Web 2.0 avails its users the ability to synchronize with handheld or mobile devices such as smartphones.

However, mentorship programs taking place via the internet is not a characteristic of Web 2.0 but that of Web 3.0 (e-mentoring).
