Units for measuring computer memory

1 answer:

6 0

A kilobyte (KB) is 1,024 bytes, not one thousand bytes as might be expected, because computers use binary (base two) math, instead of a decimal (base ten) system. Computer storage and memory is often measured in megabytes (MB) and gigabytes (GB). A medium-sized novel contains about 1 MB of information.

Consider two different implementations, M1 and M2, of the same instruction set. There are three classes of instructions (A, B, a

ANTONII [103]

Answer:

a) the average CPI for machine M1 = 1.6

the average CPI for machine M2 = 2.5

b) M1 implementation is faster.

c) the clock cycles required for both processors.52.6*10^6.

Explanation:

(a)

The average CPI for M1 = 0.6 x 1 + 0.3 x 2 + 0.1 x 4

= 1.6

The average CPI for M2 = 0.6 x 2 + 0.3 x 3 + 0.1 x 4

= 2.5

(b)

The average MIPS rate is calculated as: Clock Rate/ averageCPI x 10^6

Given 80MHz = 80 * 10^6

The average MIPS ratings for M1 = 80 x 10^6 / 1.6 x 10^6

= 50

Given 100MHz = 100 * 10^6

The average MIPS ratings for M2 = 100 x 10^6 / 2.5 x 10^6

= 40

Machine M2 has a smaller MIPS rating

Changing instruction set A from 2 to 1

The CPI will be increased to 1.9 (1*.6+3*.3+4*.1)

and hence MIPS Rating will now be (100/1.9)*10^6 = 52.6*10^6.

Which of the following is true about binary search. A. It uses binary numbers in its algorithm B. It is slower than sequential s

trapecia [35]

Answer:

A. It uses binary numbers in its algorithm

Explanation:

A Binary search is a type of algorithm designed to look through only a sorted array of data for a particular item.

It is more efficient (faster) than sequential search since the algorithm doesn't have to look up the entire array of data, but simply repeatedly divide in half the section of the array that could contain the searched item.

zhannawk [14.2K]

Solution :

public Book( $\text{String title}$ , String author, $\text{String publisher}$ , int $\text{copiesSold}$ ) {

this. $\text{title}$ = $\text{title}$ ;

this. $\text{author}$ = $\text{author}$ ;

this. $\text{publisher}$ = $\text{publisher}$ ;

this. $\text{copiesSold}$ = $\text{copiesSold}$ ;

b). $\text{public String}$ getTitle() {

return $\text{title}$ ;

}

$\text{public void}$ setTitle( $\text{String title}$ ) {

this. $\text{title}$ = $\text{title}$ ;

}

$\text{public String}$ getAuthor() {

return author;

}

$\text{public void}$ setAuthor(String author) {

this. $\text{author}$ = $\text{author}$ ;

}

$\text{public String}$ getPublisher() {

return $\text{publisher}$ ;

}

$\text{public void}$ setPublisher(String $\text{publisher}$ ) {

this. $\text{publisher}$ = $\text{publisher}$ ;

}

public int get $\text{copiesSold}$ () {

return $\text{copiesSold}$ ;

}

$\text{public void}$ set $\text{copiesSold}$ (int $\text{copiesSold}$ ) {

this. $\text{copiesSold}$ = $\text{copiesSold}$ ;

}

3.1.2 Quiz: What Can Information Technology Do for You? Question 8 of 10 What is one reason why a business may want to move enti

balu736 [363]

Answer:

C. To focus on a global market

Explanation:

Information technology can be defined as a set of components or computer systems, which is used to collect, store, and process data, as well as dissemination of information, knowledge, and distribution of digital products.

An information technology interacts with its environment by receiving data in its raw forms and information in a usable format.

Generally, it is an integral part of human life because individuals, organizations, and institutions rely on information technology and systems in order to perform their duties, functions or tasks and to manage their operations effectively. For example, all organizations make use of information technology and systems for supply chain management, process financial accounts, manage their workforce, and as a marketing channels to reach their customers or potential customers.

Additionally, an information system or technology comprises of five (5) main components;

1. Hardware.

2. Software.

3. Database.

4. Human resources.

5. Telecommunications.

Hence, information technology or system relies on the data it receives from its environment, processes this data into formats that are usable by the end users.

One reason why a business may want to move entirely online is to focus on a global market through the use of social media platforms and networks to reach out to customers in various geographical location.
