Plant manufactory devices central of computer networks, systems, complexes and electronic digital ma
A computer network is a digital telecommunications network which allows nodes to share resources. In computer networks, computing devices exchange data with each other using connections data links between nodes. These data links are established over cable media such as twisted pair or fiber-optic cables , and wireless media such as Wi-Fi. Network computer devices that originate, route and terminate the data are called network nodes. Two such devices can be said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other. In most cases, application-specific communications protocols are layered i.VIDEO ON THE TOPIC: Computer Networking Complete Course by Google - Beginner to Advanced

Today's world runs on computers. Nearly every aspect of modern life involves computers in some form or fashion. As technology is advancing, the scale of computer use is increasing. Computer users include both corporate companies and individuals. Computers are efficient and reliable; they ease people's onerous jobs through software and applications specific to their needs offering convenience. Moreover, computers allow users to generate correct information quickly, hold the information so it is available at any time.
Computers and technology affect how we live, work and entertain ourselves. From voice-powered personal assistants like Siri, Alexa, and Cortana to more underlying and fundamental technologies such as behavioral algorithms, suggestive searches and autonomously-powered self-driving vehicles boasting powerful predictive capabilities. Computers offer a quicker way to gain information which is by providing an internet access.
Up to this moment, many internet browsers and applications have been invented. For instance, Google Chrome is one of the largest web based applications used by everyone in the world for reliable source for information.
Computer skills are required to be hired in companies these days. Imagine if two candidates are interviewed, one of them knows nothing about computers while the other does. The employer will definitely hire the latter. Furthermore, with computer skills, one can build his own company and expand his business.
He could perhaps work online and export his goods or service. Not only have computers become more integrated in our lives. They are increasingly becoming more essential in any aspect of life. As computers become more essential, the skill to operate them also become more essential. Those who have not had the opportunity to learn computer skills when computers were not as widespread have started to, or are forced to learn to use them as computer skills have become a necessity in order to be a productive and contributing person in not only the workplace but also in society.
Proof of the ever increasing integration in our lives comes from the fact that almost anything can be done with the use of computers. You can now order food, even groceries, through the computer, you can now watch almost anything on your computer, you can now work from home or you can play games to procrastinate at work through the help of computers, you can even conduct interviews through your computer, there are so many things that a computer is capable of that learning the skills to fully reach the potential of computers is a priority.
A computer is a good product to have at home. There are so many benefits to owning your own computer. It allows you to be able to write letters, articles, stories, reports and other things easier and faster. If you own a printer, you can easily write a letter to a friend or family member, print it out and send it to them.
You can save your written documents on your home computer and have easy access to them when you need them again. Having a computer at home allows you to have access to work from home jobs such as research, data entry, writing and other work-from-home jobs. With a computer at home, you can easily communicate with friends and family through email, social networks and instant messaging.
Using a computer to communicate is cheaper than calling friends and family long distance. You can also communicate with co-workers, your boss and anyone else you meet on the Internet through your own computer. People usually go to the library for their research.
If you have your own computer at home, you don't have to travel to the library when you need to research something. Log on to the Internet and research whatever you need with your computer at home. When you need to know something fast you can look it up on Google or your favorite search engine. Having a computer at home gives you access to learning all kinds of things through research. This will save you on gas charges instead of having to drive to the library.
Having a computer at home means your own personal entertainment source. There are literally thousands of games on the Internet which you can play anytime you want to. You can also join social networks and interact with your friends on a daily basis. With a computer at home and the Internet, students can now get a college degree from home. There are a lot of different schools that allow students to take college classes online.
Using a computer and the Internet can get you a degree at your own pace and faster than going to a college campus. While almost every household has at least one personal computer within it, desktop and laptop computers are no longer the only computers found in the home.
Many homes have numerous computers embedded throughout. Thermostats, appliances, entertainment systems and home security systems are just a few examples of things in a home that can be controlled by an internal computer. These smart homes are capable of so much. All of the devices work on a network and often communicate wirelessly. Home security systems can be monitored from an offsite location.
Lights can be turned on and off remotely. Some thermostats can even learn and adapt to homeowner preferences. Smart homes are becoming more and more common. Technology is advancing at a rapid rate and smart homes are expected to become the norm in the very near future. The smart devices and appliances can be controlled from personal computers, or other network devices like smart phones.
Some people believe that these homes will eventually be smart enough to recognize the inhabitants and adapt to the needs,  giving the phrase computers in the home a whole new meaning. At most colleges and universities, their students are familiar with blackboard,  a course management system that is used quite frequently in order to stay in touch with teachers, figure out homework assignments, and keep track of grades.
While not all classes utilize this technology, it can be very helpful especially for online courses. With technology growing and advancing so far forward we now have the ability to learn and take classes from the comfort of our own home. While many students still go on campus, there is no shortage of computers. Most colleges have at least one mega lab with nearly a hundred computers. But if you wish to bring your own laptop there are plenty of wireless hot spots where you could get a connection to the internet from anywhere on campus.
Understandably lugging textbooks around campus may seem exhausting and tiring, you now have the option to get an electronic e-Book of most textbooks needed for class. Most people are knowledgeable on the fact that computers are widely-used in colleges and at universities, but let's take a step back and take a look at the ways in which computers are used in elementary schools.
The biggest benefit of a computer being used in a classroom is that it can provide many different study tools depending on the class. They can provide electronic flashcards, math games, and even things as simple as crossword puzzles.
Although a computer cannot replace a teacher, it can help expand a students independent thinking skills by allowing activities to be taken as many times as needed. Most of the activities found in classrooms are very interactive which helps keep the student interested. Also, we must not forget that because modern day children are drawn towards electronics, they are more compelled to engage in study activities on a computer rather than a sheet of paper.
Working on a computer at an early age helps build fundamental skills needed later on in life. At a young age a child can learn how to fully operate the basic external hardware of a computer like the screen, keyboard, or mouse. With enough exposure to computers and their components, a student can become more efficient for the following years of school and even their future career.
If you have seen any older movie or SpongeBob you have probably seen people getting to work grabbing their time card and getting it stamped to show what time they have arrived at work. This is called an authentication system or timesheet. This isn't the only use of computers on the job or at work in general. For instance say there is a presentation you must give to the board of directors, you might want to make a PowerPoint  to give visuals to help drive home your point.
Or perhaps you work retail and the pair of pants a customer wants is out of stock, you could easily order it online for them, and minimize the headache of shopping for those who hardly shop.
Whatever the case, computers can help. Every industry has computers. These machines have been incorporated into the fabric of every workforce. Computers have even created many fields which did not exist prior to their existence. One size does not fit all in the realm of computers, rather each has a purpose or assigned task.
The computers that fulfill similar tasks can be classed together. The categories range from small scale to industrial. An embedded computer is something that allows somewhere like an office to have appliances that range from routers to printers. Then there are mobile devices such as smart phones, tablets, and smart watches that are, for example, able to keep a New York stock broker up-to-date on the latest stocks, or instantly keep in touch with investors.
Personal computers are one order of magnitude up from mobile devices. Personal computers have the full and universal capabilities in order to have the capacity to access work from outside the workplace, as well as handle the software that might be used on the job. Midrange computers or midrange servers are yet another order of magnitude up on the spectrum. These machines are between 20 and 50 times larger than a traditional desktop computer, though their previous name was a "minicomputer" and has business and scientific applications.
These computers are often referred to as servers due to the majority of them being used as such. This leads to the final class which is Supercomputers. As the name would suggest, this type of computer is quite powerful. It calculates enormous amounts of information with countless variables to get information. These are responsible for tasks such as weather prediction, security, simulating the moment the universe came into existence, as well as helping to create the next tier of computer - which is not yet fully operational - the quantum computer.
The concept was an original hybridization, borrowing the large, touchscreen display from a tablet computer and the functionality and size from a mobile cellular phone. The idea was eventually adopted by other large manufacturers including LG GW and Nokia N , and underwent several different phases. The early generations had, in addition to a touchscreen, physical keyboards whereas the later ones do not. The Verizon Streak, produced and carried by the network, was released in Unlike most others at the time, it was restricted to phone and internet use within the household only.
Distributed control system
This installment originally available here at Tom's Hardware is the third chapter from Mueller's book. A network is a group of two or more computers that intelligently share hardware or software devices with each other. Intelligently sharing means that each computer that shares resources with another computer or computers maintains control of that resource.
A distributed control system DCS is a computerised control system for a process or plant usually with many control loops , in which autonomous controllers are distributed throughout the system, but there is no central operator supervisory control. This is in contrast to systems that use centralized controllers; either discrete controllers located at a central control room or within a central computer. The DCS concept increases reliability and reduces installation costs by localising control functions near the process plant, with remote monitoring and supervision. Distributed control systems first emerged in large, high value, safety critical process industries, and were attractive because the DCS manufacturer would supply both the local control level and central supervisory equipment as an integrated package, thus reducing design integration risk. Today the functionality of SCADA and DCS systems are very similar, but DCS tends to be used on large continuous process plants where high reliability and security is important, and the control room is not geographically remote.

Reaching new heights through digitalization
Today's world runs on computers. Nearly every aspect of modern life involves computers in some form or fashion. As technology is advancing, the scale of computer use is increasing. Computer users include both corporate companies and individuals. Computers are efficient and reliable; they ease people's onerous jobs through software and applications specific to their needs offering convenience.
Automation, robotics, algorithms and artificial intelligence AI in recent times have shown they can do equal or sometimes even better work than humans who are dermatologists , insurance claims adjusters , lawyers , seismic testers in oil fields , sports journalists and financial reporters , crew members on guided-missile destroyers , hiring managers , psychological testers , retail salespeople , and border patrol agents. Moreover, there is growing anxiety that technology developments on the near horizon will crush the jobs of the millions who drive cars and trucks, analyze medical tests and data , perform middle management chores , dispense medicine , trade stocks and evaluate markets , fight on battlefields , perform government functions , and even replace those who program software — that is, the creators of algorithms. People will create the jobs of the future, not simply train for them, and technology is already central. It will undoubtedly play a greater role in the years ahead.

Поскольку в шифровалке имелось автономное энергоснабжение, на главный распределительный щит, наверное, даже не поступил сигнал, что здесь произошла авария. - Основное энергоснабжение вырубилось, - сказал Стратмор, возникший за спиной Сьюзан. - Включилось питание от автономных генераторов. Это аварийное электропитание в шифровалке было устроено таким образом, чтобы системы охлаждения ТРАНСТЕКСТА имели приоритет перед всеми другими системами, в том числе освещением и электронными дверными замками.
Его так все называют. Им пользуются студенты, потому что билет стоит гроши. Сиди себе в заднем салоне и докуривай окурки. Хорошенькая картинка.
Сьюзан открыла рот, желая сказать, что она все понимает, но ее слова были заглушены внезапным пронзительным звуком. Тишина шифровалки взорвалась сигналом тревоги, доносившимся из служебного помещения ТРАНСТЕКСТА. Сьюзан и Стратмор в недоумении посмотрели друг на друга. - Что это? - вскрикнула Сьюзан между сигналами.
Какой немец. - Тот, что был в парке.
Но всякий раз, когда я перехватывал очередное сообщение, Танкадо был все более и более убедительным. Когда я прочитал, что он использовал линейную мутацию для создания переломного ключа, я понял, что он далеко ушел от нас.
Он использовал подход, который никому из нас не приходил в голову. - А зачем это нам? - спросила Сьюзан. - В этом нет никакого смысла.
- Он над вами издевается. А вы тем временем погибаете. - Он посмотрел на экран. - Осталось девять минут. Сьюзан, не слушая его, повернулась к Соши.
Боль пройдет, - внушал Стратмор. - Ты полюбишь. Сьюзан не слышала ни единого слова.
