Answer:

Incremental Build Life Cycle

Explanation:

In the incremental build life cycle of software development, each software tat is released have added capabilities than the previous version. The development in this case is considered to be over and done once the user is satisfied with the current features and capabilities. The first step to achieving this model is via creating a prototype and then adding features during the development life cycle.

Answer:

B. Incremental Build life cycle

Explanation:

RAD life cycle: RAD model of software development life cycle is all about coming up with prototype as soon as possible. It describes a method of software development which heavily emphasizes rapid prototyping and iterative delivery.

Incremental build life cycle: In incremental build model of software development life cycle, each release of the software have added capabilities. The development is finished when the user is okay with the present features. Focus is put on creating a working prototype first and adding features in the development life cycle. This is the correct option.

Waterfall life cycle: In a waterfall model, each phase must be completed fully before the next phase can begin and this usually takes time before a working software can be released. There is also no overlapping in the phases.

Spiral life cycle: Spiral Model can be pretty costly to use and doesn't work well for small projects. It's a risk-driven model which means that the overall success of a project highly depends on the risks analysis phase.

Why vechiles Tyres are black in colour?​
kirza4 [7]

Answer: See explanation

Explanation:

It should be noted that the rubber that tire is made from has a color that's milky white but due to the fact that carbon black is being added to the rubber, then the tire will turn to black.

The importance of carbon black to tires is immense as it acts as the stabilizing chemical compound. Also, it helps in increasing the strength of the tire and its durability and also protects the tire from ozone effect.

function calculate () { var s = 2; var x = 2; var y = 3; if (x > 4) { s=s+ 2; } else if ( y > 4) { s=s+ 4; } else { s+=3;}
MAXImum [283]

Answer:

The output of the given JavaScript code is "5".  

Explanation:

In the given JavaScript code, a method calculate is declared, inside the method, three variable "s, x, and y" is declared, in which all variable assigns a value, that is "2, 2, and 3". In the next step, a conditional statement is defined, that check value, which can be described as follows:

  • In the, If the block, x variable checks its value is greater then 4 if it is true, it will add value 2 in s variable otherwise, it will go to else if block.
  • In this block it will check the value of y variable greater then 4 if it is true, it will add value 4 in s variable.
  • In both of the above conditions is false, it will go to else section, in this, variable  "s" add value 3 in its variable, and use an alert box to print its value.

JulsSmile [24]

The program Nslookup, is available on all operating systems and provides all types of information from a DNS server and allows you to query all types of information from a DNS server and change how your system uses DNS.

The network administration command-line tool nslookup can be used to verify that your DNS servers can resolve external domain names.

Describe 6 difference of the types of computer<br>​
Trava [24]

Answer:

<h3>1. Supercomputer</h3>

One of types of computers is supercomputer. It is a computer that is at the front-line of current processing capacity, particularly speed of calculation. It is usually used to do tasks involving intense numerical calculations such as weather forecasting, fluid dynamics, nuclear simulations, theoretical astrophysics, and complex scientific computations

<h3>2. Mainframe Computer</h3>

Another computer type is mainframe computer. It is a computer that is capable of handling and processing very large amounts of data quickly. Its calculation speed can reach millions to tens of millions instructions per second (MIPS) and it can respond to hundreds of millions of users at a time.

This computer type is mainly used in large institutions such as government, banks and large corporations.

<h3>3. Minicomputer (Mid-Range Computer)</h3>

Minicomputers are a class of multi-user computers that lie in the middle range of the computing spectrum, in between the smallest mainframe computers and the largest single-user systems (microcomputers or personal computers).

Minicomputers are usually small in scale, simple in structure, easy to maintain, and low in cost. Therefore, they are often used in universities, scientific research institutions and industrial control fields.

<h3>4. Microcomputer (Personal Computer)</h3>

The term “microcomputer” was introduced with the advent of systems based on single chip microprocessors. In the early days, the microcomputers would still have been too expensive to be owned by a single individual. But in the late 20th century, microcomputers became the most common type of computer.

Therefore, the term "microcomputer" has practically become an anachronism and has been replaced the term "personal computer (PC)".

Personal computer has developed rapidly because of its small size, convenient use, low production cost, and low price. PC computing speed can reach hundreds of thousands to millions instructions per second, which can meet the requirements of data processing and scientific computing in production, scientific research, and life.

<h3>5. Workstation Computer</h3>

A workstation computer is a high-end personal computer between microcomputers and minicomputers. It is usually equipped with large-capacity memory, external storage, and large-screen displays. Therefore, it has strong data processing capabilities and graphics processing capabilities.

Workstation computers are designed and developed mainly for professional application fields like engineering design, animation production, scientific research, software development, financial management, information services, analog simulation, etc.

<h3>6. Server Computer</h3>

A server refers to a high-performance computer that provides shared information resources and various services for many users on the network at the same time in a network environment.

A server is expected to be capable of high-speed computing, long-term reliable operation (it features error-correction of RAM; redundant cooling; self-monitoring, RAID), and powerful external data throughput.

The structure of the server is similar to that of an ordinary computer. Many smaller servers are actually personal computers that have been dedicated to provide services for other computers. But they are very different in terms of processing power, stability, reliability, security, scalability, and manageability.

According to the services provided, server computers can be subdivided into database server, file server, Web server, FTP server, etc.
