Meaning of URL

URL stands for Uniform Resource Locator. It specifies the global address of web documents and web resources. The basic reason behind locating or identifying a resource on the web is access or communication. Interaction between web users and the Internet resources is possible, only if each resource on the Internet is identified in a standardized manner. A URL serves this purpose. Let’s look at the different parts that compose it and what purpose each of them serves.
The first part of the address is the protocol identifier. HTTP and FTP are examples of protocol identifiers, which indicate the protocol in use. More rightly known as the scheme, this part of the URL denotes how to connect to the web resource. It is not case-sensitive but the canonical form is lowercase.
The second part of a URL is the resource name that comprises the IP address or the domain name of the web resource. It denotes where to connect. The domain name may be followed by a port number which is separated by a colon. When specified, a connection to that port number is established. If the port is not specified,

Open Source Software Examples

There are three major types of software – Programming Software, Systems Software and Application Software. Of the three, the latter two come in two broad classifications – open source and closed source. There are many different types of application software which are open source and most of us regularly download and use them on our PC/laptop, such as VLC. In this Buzzle article, we will take a look at some popular and highly recommended open source software examples for different types of operating systems.

An open source computer software is either a systems software or an application software that is available freely in the form of source codes and the users are permitted, under the software license, to study, modify and improve the software. The Open Source Initiative has set certain parameters to determine whether a software license renders the software open source or not. These parameters are very specific and are as laid down below. In order to be considered Open Source, a software must qualify on all of these parameters.

Parameter Elaboration
Free Redistribution The software license does not restrict anyone from selling or giving away the software as part of a software package which contains programs from

Causes and Effects of Urban Sprawl

Urbanization refers to the migration of the population from rural regions to towns and cities. Man has always moved to newer places in search of better opportunities and amenities. Hence, migration is not a new phenomenon. Studies report of a steep rise in urbanization that came about in the late 19th and early 20th century. This sudden increase in urbanization can be attributed to the Industrial Revolution, which provided better economic opportunities in the cities, owing to the newly set up factories and industries.

As the cities and towns reap most of the benefits of innovations in the fields of science and technology, urbanization still continues to take place in them. As a result of this, the cities and its suburbs spill over to the rural areas along their boundaries. This spread is termed as urban sprawl. In the following Buzzle article, we will study the causes, effects, and consequences of urban sprawl and what it signifies.

Causes

The following are the main causes of urban sprawl.
Cheaper land and housing costs in the suburbs as compared to urban centers has lured many to settle in these areas.
There has been an increase in public spending for the development of infrastructure

The Digital Divide

The digital divide is the gap in access to technology between individuals, businesses, households, and geographic areas due to socioeconomic status. This digital divide can be due to one household having less money than another and, therefore, not being able to buy all the new gadgets on the market that some other families may be able to afford. It can also be due to an area of the country or the world that doesn’t have the same access to the Internet as another.

In many countries, Internet is unreliable and that leaves the user without the same access to information and conversation tools as people in other parts of the world. There are also some countries that censor the Internet for civilians for political reasons, and this can lead to a further digital divide. When discussing different levels of access of the Internet between countries, this is actually called the global divide. The term “digital divide” first came into use in the 1990s’ and was first used to refer to the different levels of access to computers between different ethnic groups in the United States of America. By 1998, the National Telecommunications and Information Administration was using the term

Intranet Vs. Internet

The age of information technology owes everything to the development of computer networking. It’s the linking up of computers on ever-widening scales, that has turned our long sought after dream of making the world’s knowledge freely accessible, into reality. If all computer networks are arranged in an ascending order of complexity and scaling, two types of networks will lie at extreme ends. One is of course the ‘Internet’ and the other, which may be functional in your company, is an ‘Intranet’.

Intranet Vs. Internet Comparison

Computer networking forms the fundamental basis of intranet and Internet. It enables the sharing of resources and information among a group of computers. The first operational computer network was created for the United States Department of Defense and was known as ‘Advanced Research Projects Agency Network (ARPANET). Since then, networking technology and architecture evolved in complexity and sophistication, to provide us with the internet. The synergy of advanced network computing hardware and sophisticated networking software based on Internet protocols has made this possible. As you will see ahead, an intranet and the Internet are two widely separated points on the scale of networking complexity, which serve to provide the most efficient form of information and

Negative Effects of Internet on Children

Internet has proved to be one of the most innovative inventions for us. It has made its presence felt in every sphere of our life, be it economy, society, health care, spirituality, etc. Prominent among its benefits is the impact it has had on the education sector. Students can now gain access to innumerable research papers, apart from getting latest updates in the field of science and technology. But as they say, “With great power comes great responsibility”, Internet has created new challenges for the society and most threatening among these is the impact it has had on children. Internet addiction has been recognized as a disorder in many countries, and rehabilitation centers have been created to help people to get over it. The sad part of this whole phenomenon is that a large proportion of Internet addicts are youngsters, who are extremely vulnerable to its ill-effects. There are several advantages and disadvantages of Internet but in this article, we will focus on its negative effects.

Internet and Children

Internet Addiction Disorder
Although studies on this disorder are in preliminary stages, it has been established that children who spend most of their time on the Internet, show a peculiar kind

Those who have been in the industry for eight to ten years can make between USD 65,000 to USD 90,000 per year. Whereas the senior professionals can earn

Waterfall Model in Software Engineering

The waterfall model is probably the oldest and the best-known development models. The role of this model in software engineering is as important as its role in software testing. It forms the basic design, using which, over the years, a number of other software process models have been developed and implemented.

Waterfall Model and Software Engineering

The waterfall model is so named because it employs a ‘top-to-down’ approach similar to the water falling from a height under the influence of gravity. The following is a brief explanation of the different phases in the waterfall model.

Phases
For developing a software for small or large project, the waterfall model suggests that you employ the phases given below, in a step-by-step manner.

First and foremost, you need to completely analyze the problem definition and all the various project requirements. This phase is commonly referred to as ‘Requirement Analysis’. Once you have thoroughly and exhaustively identified and understood all the project requirements, they are to be properly documented, after which you move onto the next phase, which is known as ‘System Design’. This involves analyzing and specifying the project’s hardware and software requirements, and their inter-relation. In this phase, the entire software aspect of the
