Computer Communications & Networks - Lab Report Example In order to test connectivity of the Internet connection, ping command is executed from the command prompt of the operating system. The syntax will be ping (space) (destination address), moreover, in order to review hops and delays in accessing the X stream server, the ‘tracert’ command can be executed from the command prompt. The syntax for this command will be tracert (space) (destination address). The ping command utilized Internet Control Message Protocol (ICMP) to check the connectivity of the destination by sending ICMP echo request on periodic basis. Moreover, the ‘tracert’ command demonstrates all the hops and delays that are in the way of that particular destination. Likewise, it is not necessary that only routers are involved in the process of establishing and exchanging information from the required host. The Ethernet is the first device that initiates and constructs a request datagram from the home computer, as it is considered to be the most pop ular Local Area Network technology that is implemented globally (Ethernet. 2007). The connectivity of the Ethernet adapter is established by both wired and wireless networks. However, in terms of wired connectivity, twisted pairs of cable are connected in to the Ethernet RJ45 socket. The other end of the wire is terminated to the router, switch or hub. In this scenario, home user will use a DSL router that will connect the home computer with the Internet Service Provider (ISP). Likewise, the Ethernet construct the datagram consisting of six parameters i.e. destination address, source address, preamble, type, CRC and data. The preamble parameter is responsible for clock synchronization of the data packets from the source and destination. Likewise, the addresses... This report approves that home Internet users do not have DNS configured. ISP is responsible to resolve the URL into IP addresses. In order to do so, the request from the home network will terminate on the ISP Network that will resolve the URL and sends the request to the relevant destination accordingly. After resolving the DNS for the URL, the router checks for the shortest and robust path for processing the quest with the help of routing protocol. Some popular routing protocols include Routing Information Protocol, Open Shortest Path First, Border Gateway Protocol. After identifying the most suitable path for the request, the connection to the X stream server will be established. Encapsulation of User datagram protocol, IP and Ethernet takes place before sending it to the router for resolving DNS query. This essay makes a conclusion that the first section covered mandatory requirements as well issues that occur on physical layer connectivity. Likewise, we have discussed the Ethernet packet header along with its purpose in details. The next discussion was about CSMA/CD, as the request needs space to fulfill the execution. Next we have discussed the ARP command along with the discussion of a MAC address packet. Moreover, in the next section we have discussed the network layer connectivity and router functionality. We have also put some light on routing protocols and their functions. Furthermore, in the last section, DNS query construction is discusses along with socket connections by incorporating HTTP, TCP/IP, UDP and ARP for opening the X stream web page on the home user browser.

Changes that Women Have Undergone through the Years Term Paper

Changes that Women Have Undergone through the Years - Term Paper Example The question raising the issues then is that of how are they able to perform all the responsibilities that shape their existence within the society and their role as glue-holders of their families. As earlier mentioned, there are numerous women who are known for social service that actually affects the development of the entire human communities today (Anderson, 2003, 15). Among the said women are Hillary Clinton and the late Mother Theresa. There are still others, however, their names are too numerous to be listed herein. However, no matter how individually different they may be, they all have the same performing practices in terms of facing the responsibilities that they have upon the society's values and their own aspirations in making great changes in life. (Anderson, 2003, 14) Women are traditionally known to have a responsibility of giving care to their homes, their families. It has always been an accepted idea with regards the role of women that they are supposed to prioritize their families since this is the main responsibility that identifies their being. However, as years advance, the role of women in society also expands. Now, they do not simply stay inside the four walls of their homes. They are now able to take employment outside their homes and they are even able to take responsibilities in the political positions at present. It could not be denied too that even though women are given larger chances of making changes today, they are still able to do all the responsibilities that they are primarily appointed with by womanhood itself (Cantarow, 1980, 13). However, it is undeniable too that most of the women who are working for the society who immediately become social images are noted for their capability of primarily coming up with the possibiliti es of performing their social responsibilities.
