The Internet is a heterogeneous, open, secure, scalable, fault-tolerant, concurrent and transparent system.
Internet is the largest example of a distributed system. Internet in made of humongous amount of systems and devices interconnected to each other via a common medium. Following are the attributes of internet:
Heterogeneity :
Heterogeneous nature of internet is one of the main factors for popularity of internet.
We can be connected to internet by multiple devices – mobile phones, laptop computers, PDAs, etc.
Moreover, internet itself is made up of millions of small sub-networks. Each sub-network may use different protocol for data transfer and communication within the network.
The programming language and hence the data type used by each system may vary as each system is implemented as a whole and independent of others.
Each

There are multiple users at a given time who are accessing internet.
Concurrent access means resource sharing. These resources can include the bandwidth, CPU, etc.
To make sure that all users have seamless access to same resources like network links, we need to have sufficient bandwidth so bottlenecks are not created.
As of now, hundreds of thousands of users are accessing google.com. Google needs to make sure it has a servers which holds the capacity to serve these many users.
Load balancing comes into picture here also considering the large number of requests to the servers.
Most of the concurrently accessed material is read only but many applications like google docs, provide concurrent read-write access, which is again made possible through internet.
Transparency:
Internet has high amount of transparency.
Transparency is basically hiding the underlying implementation, and providing access.
When programs are implemented in different programming language, the transparent nature of internet allows to have smooth communication between those program despite being in different languages or
The internet designed for the purpose of sharing information. Never before in history has it been so simple to send information from one place to another. While it was originally designed for storing information within large corporations, the internet today is used as an information highway. Due to this, things like music and movies can be shared very quickly via the internet. Property of one person can be shared quickly and efficiently. While there are many things to be gained from this, unfortunately it puts the manufacturers of this digital information at a disadvantage.
A distributed system is a collection of independent computers (nodes) that appears to its users as a single coherent
With technology being as worldwide and as it is today, such information can easily get into the wrong hands. Such as hackers or people who steal
The Internet is a global network connecting millions of personal, institutional and company computers. The number of computers used by the internet is growing rapidly. The United States is connected with over 100 countries worldwide and linked together to exchange of data, news and opinions. The Internet is decentralized design. This means that there isn't just one computer that stores all of the information from the Internet. There are many independent host servers located throughout the US and the world that store the information made available to the global Internet community.
This is a concern because hackers can hack into an unsecure network and steal valuable information from individuals or companies without their knowledge. Downloading music from the site opened up thepossibility of identity theft.
There are two kinds of systems, centralized and distributed. A distributed system consists of a single component that provides a service, and one or more external system that access the service through a network. In other hand, a decentralized system consists of many external systems that communicate to each other through one or more major central hubs.
...f data dangerous online through such networks especially that there is not much space for privacy to its users.
Although initially conceived as a form of communication during wartime, developed by United States Department of Defense. The precursor of the Internet was created by a group called, The Advanced Research Projects Agency Network (ARPAnet), as a distributed communication network (Richard Campbell, 2013)in case of a nuclear catastrophe, ARPAnet was in principle just a form of communication from one point to another which had users log into what they called a network, thus allowing for information to be shared whenever necessary. The way information was able to travel from one location to another within a network was in broken down form of compressed data called packet switching. “This is a method of breaking data files into small packets or chunks in order to send them across a network” (Teach-ICT.com Limited, 2002). This was in fact, laying out the outsets of what was then to become, the Internet.
As can be seen, from the information presented, the need for laws and restrictions concerning internet data collection is greatly needed. Moreover, the government can search private citizens data without warrant or cause. Also, companies are not only collecting internet user data but also selling it. The companies and agencies who commit such crimes should be fined or either closed down. In closing, the privacy and security of individuals on the internet should be upheld by the United States government.
The Internet offers a huge wealth of information, both good and bad. The Internet began as a small university network in the United States and since then has blossomed into one of the biggest if not the biggest telecommunications network covering the entire world. It can be considered as one of the most valuable types of technology. During the past several years we have come to become more and more dependent on the Internet and in particular moving huge chunks of data across large distances. The Internet allows people to communicate with each other across the world within mere fractions of seconds with the help of E-mail. The Internet also allows for expressing opinions and obtaining up-to-date information from the World-Wide-Web. New software is being developed everyday which uses Internet as the carrier for long distance voice calls and video conferencing which would hold the key to the future of our society.
The Internet was originally designed in the U.S. as a defence communication medium. At present, Internet technology is being widely used because it provides a variety of relatively in expensive services. If technologies are to used,they will need to offer something new to the users. They may be faster, cheaper, provide richer information, provide more information or offer sharing alternatives.
The Internet has revolutionized the computer and communications world like nothing before. The Internet enables communication and transmission of data between computers at different locations. The Internet is a computer application that connects tens of thousands of interconnected computer networks that include 1.7 million host computers around the world. The basis of connecting all these computers together is by the use of ordinary telephone wires. Users are then directly joined to other computer users at there own will for a small connection fee per month. The connection conveniently includes unlimited access to over a million web sites twenty-four hours a day, seven days a week. There are many reasons why the Internet is important these reasons include: The net adapts to damage and error, data travels at 2/3 the speed of light on copper and fiber, the internet provides the same functionality to everyone, the net is the fastest growing technology ever, the net promotes freedom of speech, the net is digital, and can correct errors. Connecting to the Internet cost the taxpayer little or nothing, since each node was independent, and had to handle its own financing and its own technical requirements.
Different devices which are interconnected with each other and communicate with each other, form an internet.
The internet is a vast network of computers that connects many of the world’s businesses, institutions, and individuals. It allows millions of people throughout the world to send and receive messages to each other, share information, and play games (Naughton 4). It was initially designed to aid the government and help people expand academically, but it is now becoming more commercialized and used in ways that it was not made for.
The era of computers and technology has begun. Without computers in this day in age something’s would not even be possible. Although, technology has advanced our uses in society and race as a whole everyday life it also has created many issues. One of the biggest issues is system privacy. There are many things that threaten our safety online. For instance, have you ever sat down in your favorite café, or bookstore and surfed the web. Many of us have, but not all of us know the threat of something so innocent can be if your information gets in the wrong hands while out in public.
