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
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
First up, the Internet. The Internet is a vast collection of different networks that use certain common protocols and provide certain common services. In this section, they go into great detail about the history, like how it started as a military project, and even talk about how users gain access to the modern version through ISPs (Internet Service Providers). For our second example, the author writes about third-generation mobile phone networks, or 3G. Initially deployed in 2001, this systems offers both digital voice and broadband digital data services. One benefit to this system is mobility which comes from the ability of data to be handed off from one cell tower to
The internet consists of a global network of computers joined together to form one large interconnected network. It relies on Routers, Naps, ISPs, DNS and powerful servers to connect the network.
The Internet was started over three decades ago as a US government sponsored project. The Internet originally connected several universities and the government; it eventually grew to include some private companies/research labs. As such, the initial users of the Internet were scientists/technologists who were well versed in the workings of the network (and who did not have the malicious intents of modern hackers). The motivation of the Internet at this time was to provide a robust nationwide communication network and to allow for the sharing of scientific research/resources around the nation1. The original architecture of the Internet is often described as an end-to-end architecture. The end-to-end architecture is a decentralized one in which a “mechanism should not be placed in the network if it can be placed at the end node” 2. This type of design keeps the core of the network simple and generic.
The Internet is a public, global network of networks which is based on Internet Protocol (IP) and related standards (http://www.teleshuttle.com/media/extradef.htm). The Internet was designed to provide a standard means of interconnecting networks so that any system could communicate with any other system, regardless of physical location. It operates as a confederated network of networks (an "internet"), and offers universal accessibility (http://www.teleshuttle.com/media/extradef.htm).
In distributed operating system if one node fails the remaining nodes provide the system the backup needed. This results in improved reliability and can continue the operation. The enhanced availability of resources can make the distributed system to use multiple communication paths and use redundant resources. The security in these system provide protection against any unauthorized access and prev...
Now is a time which the information is extremely development. A lot of datas are stored by the form of electronic messages. The transmission of the information is often through electronic medium such as mobile phone communication, electronic commerce, the on-line chat service etc. Unfortunately, those way of transmit the information are not safe. The message that we delivered is possible be stolen or monitored. If we have no appropriate protect measure, so once the important messages leaks out, the result may be inconceivable.
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 consists of a three level hierarchy composed of backbone networks (e.g. ARPAnet, NSFNet, MILNET), mid-level networks, and stub networks. These include commercial (.com or .co), university (.ac or .edu) and other research networks (.org, .net) and military (.mil) networks and span many different physical networks around the world with various protocols, chiefly the Internet Protocol.
The Internet is made up of thousands of computers from around the world, these computers are linked up together though cables and satellites. Often people think the Internet is a “cloud,” but it’s a physical object. It is made up of servers and clients, which are usually made out of plastic and metal, containing a series of electronic circuits, for example; wires, glass, fibre optics, chips and other simular parts to used make a circuit. The Internet is used for a wide range of activities; these are, sending files, research on the World Wide Web (WWW), online chatting and electronic mail service. Humans are so dependant on the Internet because it holds most of our private information in servers around the world.
The Internet is a gigantic collection of millions of computers that are all linked together on a computer network.
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.
The internet, a vast interconnected network of data streaming across the world, through a web system of wired connections that spans to the length that wide as the globe. The precursors of the internet date back to research by the government of the United States, done back as early as the 1960s. The actual internet origins occurred some time in the mid-1980s as generations of exponential growth for computers of personal, mobile, and institutional reach the networking internet. Since the 1980s, the internet was mainly used solely for academic purposes, but commercialization of the internet in the 1990s led to the popularization and incorporation into the public use of the internet in daily life. As of mid-2012, 1/3 of the population of the world currently uses the internet, nearly 100 times more than the amount of people that used it in 1995.
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 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.
