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.

A company requires an Ethernet connection from the north end of its office building to the south end. The distance between conne
BlackZzzverrR [31]

Answer:

A company requires an Ethernet connection from the north end of its office building to the south end. The distance between connections is 161 meters and will need to provide speeds of up to 10 Gbps in full duplex mode. Which of the following cable combinations will meet these requirements?

ANSWER: Use multi-mode fiber optic cable

Explanation:

MULTI-MODE FIBER OPTIC CABLE

For Ethernet distances up to 100 meters, the Copper CATX cable will do just fine. In the question, we are dealing with a distance of up to 161 meters, so we need an Ethernet extension. LAN extension over fiber optic cable with media converter can be used to convert the Ethernet cable runs from copper to fiber. Multi-mode fiber has a range of 550 meters for 10/100/1000 Ethernet links.

Multi-mode optical fiber is commonly used for communication over short distances, like within a building or on a campus. They are capable of data rate of up to 100 Gbps, which surpasses the requirements in this question. They are more economical in this case as they are not as expensive a the single-mode optical fiber cable. Fiber optic cable has the advantage of being immune to electromagnetic interferences, spikes, ground loops, and surges. This makes it more suited for this purpose.

Why do you think flowers are a popular topic for macro photography? Do you think you’d like to photograph flowers?
Helen [10]

Why do you think flowers are a popular topic for macro photography?

Macro photography is the part of photography that focuses on taking pictures of very small objects (or small parts of larger objects).  Popular subjects are insects, flowers and small mechanical parts.

Flowers are a very popular subject because they always have lots of interesting details no matter how close you zoom in, like insects.  Flowers however tend to be easier to photograph because they move a lot less than insects.

Do you think you’d like to photograph flowers?

Yes, because it's a new way to look at them.
