The Network Interface Card free essay sample

Check the workstations using ipconfig /all and find out if the ip range is within the address range you assigned, if it is a different address then the workstation failed to contact the DHCP server and has gone into apipa mode. The Network Interface Card might be assigned an incorrect driver. Another possible cause of the problem is that the patch cable is not plugged into the Network Interface Card, or is not connected to a switch on the other end. However, it could be that the server has run out of IP addresses that it can assign to clients. You can easily tell if this is the problem by comparing the size of the DHCP address scope to the number of devices on your network that request IP addresses from the DHCP server. We will write a custom essay sample on The Network Interface Card or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page But since only some of the workstations have got addresses the problem might be the DHCP server. Start off by doing some ping tests to verify that the DHCP server is able to communicate across the network. If the DHCP server is able to communicate with other computers on the network, then I recommend verifying that the DHCP server has an IP address that is compatible with the scope that the server is configured to assign addresses from. The server itself has to be assigned a static address in the same subnet range, such as 192. 168. 0. 199. If this still doesn’t solve the problem make sure that the DHCP server is still authorized by the Active Directory to lease IP addresses. You should also check to verify that the scope is active, and that the necessary services are running on the DHCP server. Exercise 1: DNS scenario. You will need to setup a primary DNS server in the larger branch office. Configure it as a primary forward lookup zone for the domain name of your company. Before you install DNS make sure your computer has a static ip address so it does not get one from the DHCP server. In the small branch setup a second DNS server. Configure it as a secondary forward lookup zone with the same domain name as the primary DNS server.

What Third World and Developing Countries Means

What Third World and Developing Countries Means The world is divided into those countries that are industrialized, have political and economic stability, and have high levels of human health, and those countries that do not. The way we identify these countries has changed and evolved over the years as we have moved through the Cold War-era and into the modern age; however, it remains that there is no consensus as to how we should classify countries by their development status. First, Second, Third, and Fourth World Countries The designation of Third World countries was created by Alfred Sauvy, a French demographer, in an article that he wrote for the French magazine, LObservateur in 1952, after World War II and during the Cold War-era. The terms First World, Second World, and Third World countries were used to differentiate between democratic countries, communist countries, and those countries that did not align with democratic or communist countries. The terms have since evolved to refer to levels of development, but they have become outdated and are no longer used to distinguish between countries that are considered developed versus those that are considered developing. First World described the NATO (North Atlantic Treaty Organization) countries and their allies, which were democratic, capitalist, and industrialized. The First World included most of North America and Western Europe, Japan, and Australia. Second World described the communist-socialist states. These countries were, like First World countries, industrialized. The Second world included the Soviet Union, Eastern Europe, and China. Third World described those countries that did not align with either the First World or Second World countries after World War II and are generally described as less-developed countries. The Third World included the developing nations of Africa, Asia, and Latin America. Fourth World was coined in the 1970s, referring to the nations of indigenous people that live within a country. These groups often face discrimination and forced assimilation. They are among the poorest in the world. Global North and Global South The terms Global North and Global South divide the world in half both geographically. The Global North contains all countries north of the Equator in the Northern Hemisphere and the Global South holds all of the countries south of the Equator in the Southern Hemisphere. This classification groups the Global North into the rich northern countries, and the Global South into the poor southern countries. This differentiation is based on the fact that most of developed countries are in the north and most of the developing or underdeveloped countries are in the south. The issue with this classification is that not all countries in the Global North can be called developed, while some of the countries in the Global South can be called developed. In the Global North, some examples of the developing countries include: Haiti, Nepal, Afghanistan, and many of the countries in northern Africa. In the Global South, some examples of the well-developed countries include: Australia, South Africa, and Chile. MDCs and LDCs MDC stands for More Developed Country and LDC stands for Least Developed Country. The terms MDCs and LDCs are most commonly used by geographers. This classification is a broad generalization but it can be useful in grouping countries based on factors including their GDP (Gross Domestic Product) per capita, political and economic stability, and human health, as measured by the Human Development Index (HDI). While there is debate as to at what GDP threshold an LDC becomes and MDC, in general, a country is considered an MDC when it has a GDP per capita of more than US $4000, along with a high HDI ranking and economic stability. Developed and Developing Countries The most commonly used terms to describe and differentiate between countries are developed and developing countries. Developed countries describes the countries with the highest level of development based on similar factors to those used to distinguish between MDCs and LDCs, as well as based on levels of industrialization. These terms are the most frequently used and the most politically correct; however, there is really no actual standard by which we name and group these countries. The implication of the terms developed and developing is that developing countries will attain developed status at some point in the future.

The motion of the Earth around the Sun and the effect of this in Essay

The motion of the Earth around the Sun and the effect of this in respect of temporal orientation - Essay Example The motion of the Earth around the Sun and the effect of this in respect of temporal orientation In the 18th and 19th century scientists discovered the Sun to be only one star among from an infinitesimal number of stars and in the 20th century it revealed that Milky Way is only one galaxy among the myriads of similar galaxies. Nowadays Einstein’s theory of relativity is universally accepted. Relying on the equivalence principle, it has become unnecessary to determine the centre of the Cosmos. In other words, one can elect either the Sun or the Earth to be the centre (or reference point) of the solar system. All we know, everything is in motion in the Universe. The Earth is spinning around its axis and moves on an orbit around the Sun. These motions cause the alternation of days and nights and that of seasons. Observing from the Earth it appears as if the Sun were moving in the sky, following a regular path on the celestial heaven. We call Ecliptic the apparent way the Sun makes in a year in the sky. More precisely, it is the intersection of the celestial sphere with the ecliptic plane. The ecliptic plane contains the Earth’s mean orbital plane in the solar system. Except for two, most planets in the solar system are moving almost on the same plane, therefore these planets appear from the Earth always close to the Ecliptic. The two exceptions are Mercury and Pluto whose orbital planes deviate from the ecliptic plane by 7Â ° and 17Â °, resp.
