Answer:

From DRAM to DDR4

Explanation:

RAM stands for <em>Random Access Memory.</em> In 1968, Mr. Robert Dennard at IBM's Watson Research obtained the patent for the one-transistor cell that will eventually substitute the old magnetic core memory allocated in computers of the time. By 1969 Intel released the TTL bipolar 64-bit SRAM (Static Random-Access Memory) as well as the ROM "Read Only Memory"; also in 1969 it evolved into "<em>Phase - change memory - PRAM - </em>". However this evolution was not commercialized, Samsung expressed its interest in developing it. In 1970 the first DRAM product was commercially available; it was developed by Intel. In 1971 it was patented EPROM; in 1978 George Perlegos developed EEPROM.

By 1983 a nice breakthrough happened with the invention of SIMM by Wang Labs. In 1993 Samsung came up with KM48SL2000 synchronous DRAM (SDRAM), this variation soon turned into an inductry standard.

In 1996 DDR began a revolution in the memory sector, then in 1999 RDRAM. Both DDR2 SDRAM. DDRR3 and XDR DRAM were commercialized. Finally in 2007 and 2014 the developments of DDR3 and DDR4 were available for the general public.

What are the basic characteristics of object-oriented analysis and design (OOAD)? How does OOAD compare to structured analysis a

juin [17]

Answer:

Basic characteristics of OOAD and compression with SAD can be defined as follows:

Explanation:

The Object-oriented analysis is described as a design and analysis system like an application, that uses Oops programming. It is the measurement model, that is the presentation, which became a part of the object-based review.

The features of OOAD can be defined as follows.

The complex issues are simply solved.
The operation of very fast recovery.
The stability in condition changes.
Its conceptual method for resolving its extremely complex problems.

The difference in OOAD and SAD can be defined as follows:

The OOAD mainly focuses upon the design of objects, it can be used in highly complex logical systems, whereas the SAD focuses on data analysis systems and processes.
The OOAD uses the framework to target data, but the SAD is process-oriented. It uses class and UML diagrams, but SSAD uses DFDs to extract the element, it has many limited steps to prepare and execute, but OOAD relies mostly on initial growth. This method is being developed in the course of the process.

lesya692 [45]

Answer:

True

Explanation:

In order to be compliant with the NIST publications, policies must include key security control requirements. One of these key requirements includes certification and accreditation, which is a process that occurs after the system is documented, controls tested, and risk assessment completed. It is required before going live with a major system. Once a system is certified and accredited, responsibility shifts to the owner to operate the system is a true statement.

Given class triangle (in files triangle.h and triangle.cpp), complete main() to read and set the base and height of triangle1 an

kow [346]

The C++ program that would complete the main () and set the base and height of triangle1 and of triangle2 is:

main.cpp

#include <iostream>

#include "Triangle.h"

using namespace std;

int main()

{

Triangle Tri1;

Triangle Tri2;

double base1, height1, base2, height2;

cout << "Enter a base for your Triangle1: ";

cin >> base1;

cout << "Enter a height for your Triangle1: ";

cin >> height1;

cout << endl;

cout << "Enter a base for your Triangle2: ";

cin >> base2;

cout << "Enter a height for your Triangle2: ";

cin >> height2;

cout << endl;

cout << "################################" << endl;

cout << "Triangle with larger area:" << endl;

if ((0.5)*base1*height1 > (0.5)*base2*height2){

Tri1.setValues(base1, height1);

Tri1.getValues();

cout << "Area: " << Tri1.getArea() << endl << endl;

}

else{

Tri2.setValues(base2, height2);

Tri2.getValues();

cout << "Area: " << Tri2.getArea() << endl;

}

return 0;
