Answer:

Several of the subsystems evolved during the program through design changes: The parachute system, essential for booster recovery, was redesigned with larger parachutes in 1983. Frangible nuts, used in the space shuttle pad hold down and release system, were redesigned in 2008.

Write a flowchart and C code for a program that does the following: Uses a do...while loop. Prints the numbers from 1 to 10 with

emmasim [6.3K]

Answer:

create the integer variable and initialize it to one, with the do statement, increment the variable by one and print it, then the while statement checks if the variable is less than or equal to 10.

#include <iostream>

using namespace std;

int main(){

int i = 1;

do {

cout<< i << "\n";

i++;

}

while (i <= 10);

}

Explanation:

The C++ source code initializes the integer variable i to one and increments and print the value if the value is less than or equal to ten. The do-while statement executes a block of code before the condition is implemented.

A network administrator is reviewing a network design that uses a fixed configuration enterprise router that supports both LAN a

tester [92]

Answer:

a modular router

Explanation:

A modular router is a type of router that will provide multiple slots, this will enable the network engineer to either change or increase the number of space the router has.

A layer 3 switch cannot provide a WAN connectivity even though it can increase the number of ports on a router. The concept of PoE capability of any device have nothing to do with the number of ports it has. If the Engineer decides to use another fixed configuration router it will still lead to the same problem in the future because it cannot guarantee or provide the flexibility of future growth adaptation which can be given by a modular router if put in use.

Which type of app is the best choice when it is critical to be able to use the device's features but performance is not critical

lisov135 [29]

Answer:

Hybrid.

Explanation:

A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer on how to perform a specific task and solve a particular problem.

A software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications. There are seven (7) main stages in the creation of a software and these are; planning, analysis, design, development (coding), testing, implementation and execution, and maintenance.

Some of the models used in the software development life cycle (SDLC) are;

I. A waterfall model: it can be defined as a process which involves sequentially breaking the software development into linear phases. Thus, the development phase takes a downward flow like a waterfall and as such each phase must be completed before starting another without any overlap in the process.

II. An incremental model: it refers to the process in which the requirements or criteria of the software development is divided into many standalone modules until the program is completed.

III. A spiral model: it can be defined as an evolutionary SDLC that is risk-driven in nature and typically comprises of both an iterative and a waterfall model. Spiral model of SDLC consist of these phases; planning, risk analysis, engineering and evaluation.

Basically, softwares are categorized into three (3) main categories based on the development platform and these are;

a. Web application.

b. Native application.

c. Hybrid application.

A hybrid application is a type of software application that is designed based on the combination of the elements of both web applications and native applications.

Typically, a hybrid application is a web application that is developed in a native application shell, using a standardized web programming language such as CSS, JavaScript, and HTML.

Generally, a hybrid application avails a programmer the opportunity to write a code for a mobile application once while accommodating or being compatible with multiple app platforms such as Android, Windows, iOS, etc.

Hence, a hybrid application is the best choice of an application when it's critical for the end users to be able to use the features associated with a device such as a mobile phone but performance isn't critical.
