Network:

A computer network or data network is a telecommunications network which allows computers to exchange data. In computer networks, networking devices exchange data with each other using a data link. The connections between nodes are established using either cable media or wireless media.

There are 3 types of networking

1. Local area network, or LAN
2. Metropolitan area network, or MAN
3. Wide area network, or WAN

LAN:

A local area network, or LAN, consists of a computer network at a single site, typically an individual office building. A LAN is very useful for sharing resources, such as data storage and printers. LANs can be built with relatively inexpensive hardware, such as hubs, network adapters and Ethernet cables.
The smallest LAN may only use two computers, while larger LANs can accommodate thousands of computers. A LAN typically relies mostly on wired connections for increased speed and security, but wireless connections can also be part of a LAN. High speed and relatively low cost are the defining characteristics of LANs.

MAN:

A metropolitan area network, or MAN, consists of a computer network across an entire city, college campus or small region. A MAN is larger than a LAN, which is typically limited to a single building or site. Depending on the configuration, this type of network can cover an area from several miles to tens of miles. A MAN is often used to connect several LANs together to form a bigger network. When this type of network is specifically designed for a college campus, it is sometimes referred to as a campus area network, or CAN.

WAN:

A wide area network, or WAN, occupies a very large area, such as an entire country or the entire world. A WAN can contain multiple smaller networks, such as LANs or MANs. The Internet is the best-known example of a public WAN.

Introduction to Internet

Internet is a global computer network providing a variety of information and communication facilities, consisting of interconnected networks using standardized communication protocols. In brief, Internet is network of network.

The Internet, sometimes called simply "the Net," is a worldwide system of computer networks - a network of networks in which users at any one computer can, if they have permission, get information from any other computer (and sometimes talk directly to users at other computers). It was conceived by the Advanced Research Projects Agency (ARPA) of the U.S. government in 1969 and was first known as the ARPANet. The original aim was to create a network that would allow users of a research computer at one university to "talk to" research computers at other universities.

Internet

An intranet is a private network accessible only to an organization's staff. Generally a wide range of information and services from the organization's internal IT systems are available that would not be available to the public from the Internet. A company-wide intranet can constitute an important focal point of internal communication and collaboration, and provide a single starting point to access internal and external resources. In its simplest form an intranet is established with the technologies for local area networks (LANs) and wide area networks (WANs)

What is WWW?

The World Wide Web (abbreviated WWW or the Web) is an information space where documents and other web resources are identified by Uniform Resource Locators (URLs), interlinked by hypertext links, and can be accessed via the Internet. English scientist Tim Berners-Lee invented the World Wide Web in 1989.

Children

Sources:Internet 

Children must pass through several stages in their lives to become adults. For most people, there are four or five such stages of growth where they learn certain things: infancy (birth to age 2), early childhood (3 to 8 years), later childhood (9 to 12 years) and adolescence (13 to 18 years). Persons 18 and over are considered adults in our society. Of course, there are some who will try to act older than their years. But, for the most part, most individuals have to go through these stages irrespective of their economic or social status.           

World Health Organization (WHO) identifies adolescence as the period in human growth and development that occurs after childhood and before adulthood. This phase represents one of the critical transitions in one's life span and is characterized by fast paced growth and change which are second only to those at infancy. Biological processes drive many aspects of this growth and development with the onset of puberty marking the passage from childhood to adolescence. The biological determinants of adolescence are fairly universal; however, the duration and defining characteristics of this period may vary across time, cultures, and socio-economic situations. This period has seen many changes over the past century- puberty for example, comes earlier than before, people marry late, and their sexual attitudes and behaviors are different from their grandparents, or even parents. Among the factors responsible for the change are education, urbanization and spread of global communication. The time of adolescence is a period of preparation for adulthood during which one experiences several key developments. Besides physical and sexual maturation, these experiences include movement toward social and economic independence, development of identity, the acquisition of skills needed to carry out adult relationships and roles and the capacity for abstract reasoning. While adolescence is a time of tremendous growth and potential, it is also a time of considerable risks during which social contexts exert powerful influences.

The History Of Bengal

 

The history of Bengal is the history of a people who have repeatedly made their highways crimson with their blood. We shed blood in 1952; even though we were the victors in the elections of 19 dead on 7 June' not form a government then. In 1958 Ayub Khan declared Martial Law to enslave us for the When could years. In 1966 when we launched the six point movement our boys were shot dead on 7 June. When their highways the movement of 1969 Ayub Khan fell from power and Yahya Khan assumed the reins of the government' after he declared that he would give us a constitution and restore democracy; we listened to him then, A lot has happened since and elections have taken place, I've met President Yahya Khan. I've made a request to him not only on behalf of Bengal but also as the leader of the party which has the majority in Pakistan; I said to him: "You must hold the session of the National Assembly on 15 January". But he did not listen to me. He listened to Mr. Bhutto instead. At first he said that the meeting would take place in the first week of March. We said "Fine, we will be taking our seats in the Assembly then". I said we will carry out our discussions in the Assembly. I went so far as to say that if anyone came up with an offer that was just, even though we were in the majority we would agree to that offer.

Dangers of Drug Addiction

 

Drug addiction is almost a common picture in Bangladesh and the number of the addict is increasing by leaps and bounds. The black claw of drug has covered many areas of the country. So, drug addiction can be compared to a plague that finishes lives indiscriminately. An irresistible attraction for some no things may be said to be addiction and the materials which cause intoxication in man are called drug. Drug can he taken in two ways, through injection and by smoking. In fact, the impact of pseudo-culture has misled a section of our youth to find relief in the tranquilizing effect of drugs. It is notable that the youth want to get rid of the frustrations resulted especially from the unemployment. Abject poverty, lack of social security, lack of any particular aim—all these are other reasons for frustration among the addict. At first, a man generally takes drugs out of curiosity, then very soon he develops the dangerous habit of taking drugs, In this way, one addicted person creates another one irrespective of male and female. There are no advantages in drug addiction. It has an unmixed disadvantage. Various intricate diseases are the fatal result of drug addiction. It carries the addict to an unreal world of dream. The poisonous reaction of drug damages the brain, impairs the internal function of the body and ultimate In leads the addict to death. Drug addiction must be thwarted to build up a sound nation. Drug dealers must be penalized by enforcing the existing laws melted to addiction and drug users. The guardians must be aware of their children's future. Government should set up more rehab centers to give active service to a greater number of addicts. A countrywide campaign should be undertaken immediately against drug addiction. To get rid of the terrible menace of drug people of all spheres should come forward with the slogan or message, "No drug, no untimely death."
