To understand the term Cyber Physical System, first we should know what is Cyber and physical. So, Cyber term related with the calculation, control and communication that are discrete, logical and switched. Physical term related with natural and man-made systems governed by the laws of physics and operating in continuous time. [Figure: 1 Cyber Physical System] [Ref. Google] So all in all, Cyber Physical System is a system in which cyber and physical system are tightly integrated at all scales and levels. The Integration of computer process and physical process is also known as Cyber Physical First reason for that is it allows us to add capabilities to physical system. And because of that we merge computing and communication with physical process and it brings us many benefits, like system will be more safe and efficient, the cost of construction and operation will be reduce and we can build a complex system that provide us a new capabilities. Other advantages are: we can get fast way to ensure safety in various real world processes, we can ensure efficiency, it will improve the quality of life for countless people, etc. But as we know that each and every coins have two sides: so similar to that Cyber Physical systems have also pros and cons with different grand challenges. The minus points of these systems are unpredictability and unemployment, computers gain self-awareness, etc. Electricity blackout is a shortage of an electric power or long term loss of the electric power in the particular area. Cause for an electricity blackout is in an electricity network, which includes faults at power stations, damage to electric transmission lines, substations or other parts of the distribution system, a short circuit or the overloading of electricity Most of the backup systems and security system will fail after a long periode of electricitiy blackout and it leads to complete failure. Most critical systems like hospitals, firrst responder facilities, water and sweage system, stock exchanges have backup power generation in particular place but it gives power backup for several hours or for a few days. For the prevantion of the electricity blackout we need to build smart power grid. A modernized electrical grid that uses analog or digital information and communications technology to gather and act on information, such as information about the behaviours of suppliers and consumers is known as a smart grid. This is used to improve the efficiency, reliability, economics, and sustainability of the production and distribution of electricity in an automated fashion[12]. The important aspects of smart grid is to electronic power conditioning and control of the production and distribution of
At this juncture, it may be somewhat difficult to accept the proposition that a threat to the telecommunications grid, both wired and wireless, in the United States could potentially be subject to a catastrophic cyber attack. After careful research on the subject, it appears the potentiality of an event of such magnitude, which either disrupts one or the other grids for a long period or destroys either, is both theoretically and realistically impossible. It may be that proponents—those who advance such theories—equate such “doomsday” scenarios as if a cyber attack would or could be of the same magnitude as a conventional or nuclear military strike. Terms such as “cyber Pearl Harbor,” “cyber 9/11” and “cyber Vietnam” have been used to describes potential catastrophic cyber attacks and yet, “Though many have posited notions on what a ‘real’ cyber war would be like, we lack the understanding of how such conflicts will be conducted and evolve.” (Rattray & Healey, 2010, p. 77). Yet, the U.S. government continues to focus on such events, as if the plausibility of small-scale cyber attacks were not as pressing.
Electricity is a commodity and a necessity. However, recent failures in power supply due to man-made errors and harsh weather question the stability of the power system. On September 9th, 2011, I personally experienced the massive power outage in Southern California. The blackout, which lasted over 11 hours from the afternoon of the 9th to the morning of the 10th, caused major traffic congestions in Los Angeles, Orange County, and San Diego. Stop lights and street lights were non-functional, making every intersection a four-way stop.
In the past, the United States has already repeatedly occurred the blackout. Especially in 1977, there was a large-scale power outages and the city became a big mess. At that time, blackout of 1977 not only resulting in significant economic losses, but also a power shortage triggered kind of serious public problems. It could be the strong contrast with the past blackout, so the blackout of 1977 was more striking and deeply impressive.
The residents of California have been experiencing “brown outs” since being declared a state of emergency in January. Not only is this a nuisance to the residents, it can prove to be quite costly as well. Each time the power is shut off and turned back on, it causes a surge. These surges have been known for “frying” appliances, computers, as well as starting fires.
Technology has been changing through the decades from the invention of the computer to the smartphone. It is how most people in today’s society tend to accomplish things and interact with others because of their busy lives. The idea of technology can be based around a concept known as cybernetics. Cybernetics basically means being able to look at things from a scientific point of view. For this purpose, is that knowing technology and how it can relate to cybernetics will be based on the following areas. These areas include the double bind theory, feedback, systems and subsystems and
Wouldn’t it be difficult living without electricity? We live in a world where technology is constantly being innovated; therefore I feel it would be. In Topeka, especially on the eastern side of town, buildings are old and so are the power lines that energize them. These lines were designed based on the design of the infrastructures that were built around the same time. Since then a lot of development has occurred and has since caused problems due to power lines being above ground. The general design was based on tracing developments via easements and sidewalks. Tim Hrenchir, an editor for the Topeka Capitol Journal, stated that weather and tree branches are the cause of forty percent of city power outages; while another eight percent is due to traffic accidents (Hrenchir). Where would you say the problem lays?
Business was also dependent upon information technology. If systems were down for some reason due to viruses or major electricity failure, the company would not be able to fill orders. The company should consider external power supply.
Cybersecurity is the technology that protects computers and networks from unauthorized personnel. Ever since computers have expanded to homes and the workplace; the need for cyber security has grown exponentially. Millions of people around the world have access to the internet at a given time, and this allows for predators to attack, scam, hack, and intrude on personal and government information. Cybersecurity is designed to counteract these attempts to ultimately allow for safe networks and computers.
In the latter half of the twentieth century society, culture and science evolved visions and capability around the common prefix ‘cyber’. It took on several virtual, computational, functional, scientific, sexual and criminal connotations. In the 21st Century, many computational notions have been replaced by ‘e’ to mean ‘of computer’ - however ‘cyber’, represented in music, words and films emerging at this time, which communicate the content of culture at the time, not simply technology – have not become ePeople, eMusic or eFilms, but remained postulated in cyberculture.
...mpany up and running through any kind of interruptions such as power failures, IT system crashes, natural or man-made disasters, supply chain/vendor problems and more.
Technology has been changing through the decades, from the invention of the radio, computer to the smartphone. It is considered to be how most people in today’s society will choose to accomplish things and interact with others because of their busy lives. There is an idea that says technology can be based around a concept known as cybernetics. Cybernetics basically means being able to look at things from an elaborated perspective that is in the aspect of a scientific point of view. For this purpose, it is about knowing technology and how it can be related to cybernetics which will be based on the following areas. These areas include the double bind theory, feedback, systems along with its subsystems, and cybernetics of cybernetics.
Since the beginning of time, mankind has waged war against each other. Over the years warfare has evolved, from fighting with sticks and stones to using gunpowder and launching missiles. The newest, and possibly most destructive, type of warfare is cyber warfare. Cyber warfare has the possibility to be more devastating than nuclear warfare.
Electricity has become a basic necessity for most people all over the world. We are depending on electricity for our everyday lives and if one day we did not have electricity we would have difficulty going through the day. I think we need to be more dependent on things that do not use electricity and only use electricity sometimes as a treat so just in case if one day electricity all goes away we could still live comfortably and still have a great life even without it.
A CPU has various discrete units to help it in these tasks for example there is an arithmetic and logic unit(ALU) that takes care of all the math and logical data comparisons that need to performed. A control register makes sure everything happens in the right sequence. The motherboard is the main circuit board inside the PC. All other components are either slotted into or soldered to this board.
There is a need for more computers in everyday life, in homes, schools and on the job. The advancement of computer technology today in all facets of the world, and life are growing to the point that everyone will need a computer to carry out their everyday life. Computer technology today is at the threshold of making life easier for everyone in the world.
