A Review On Internet Cafe Networks Information Technology Essay

A Review On Internet Cafe Networks Information Technology Essay This assignment is based on the network implementation of internet cafe which is based near the campus of University of East London. We have to design and implement a network and describe the Local Area Network and Wide Area Network management. We have to describe the cost effectiveness solutions with software and hardware we use in this network with justifications. Different layers will also be discussed at different stages in this assignment. Different IP schemes and other network suggestions will be discussed. This assignment also includes conclusion and references of the research used to build this assignment. Research method plays an important role in this assignment. Introduction to ARPANET: Advance Research Projects Agency Network (ARPANET) is the worlds first Network which gives Packet Switching and allows access over network widely. Packet switching helps in establishing a communication link. It was started in the mid 1968. It started through LAN. Phenomenon of Internet cafe: We have to work on internet cafe project which is close to University of East London. This cafe is exists on three floors, and we have to connect or share 75 computers in cost effective solutions. These all computers should be registered with the single IP address. OSI layers have to been defined at different stages on the network. TCP/IP systems relate to local area network and the internet. This network has to been defined using network layout diagram. Network Cost and specifications: This project of internet cafe would require 75 computers, 1 router, 4 switches, LAN cables and 3 printers. A normal computer specification should be: 1 GB RAM At least 2.1 GHZ processor (Intel or Atom) 150 GB hard disk 17 Display Standard USB keyboard Standard USB mouse CD/DVD ROM This is normal system specifications which could be used in internet cafe and can be easily used by the customer. Normally when computers are purchased in bulk for a computer lab or internet cafe system, loyalty discount is normally given by that provider. This specification would estimate cost around  £250  £300 as according to Currys or PC world. Dell computers are normally recommended and purchasing from DELL can be more cost effective. Router We also have to use a router. As this is internet cafe connection, so there should be powerful router connection which could enable more surfers to use internet more easily. There is a router which has recently been launched (EDIMAX BR-6574n Wireless Gigabit Router) this is really power and is available at Currys store for  £80. Apart from that, there are other NETGEAR routers as well which range starts from  £30. Switches We would also need at least 4 switches. Cisco switches are normally recommended by engineers. They are quite fast and comply with the requirement of network. It normally costs around  £100. Some Belkin and Netgear switches are cheaper as well. LAN cable We wo ­uld need LAN cables to make connections overall on the network to connect computers with switches and router. RJ-45 connector cable is used for this purpose. A 50 meter Ethernet LAN cable costs about  £5. The more length would be needed, more prices would be increased. Printers We can also add Printers to the network. It is essential in network computers to have a printer but it is not recommended or compulsory. Normally Printer ranges from  £40 that is all in one, which is better for home and office purposes as it includes Printer, Scanner and Copier. Implementation of Network: We have to work on internet cafe. Cafe has 3 floors and we have arranged 75 computers over three floors. We have to place 3 computers for server purpose. We can divide 25 computers on three floors and also 3 computers as server on third floor. To make a network local, we connect computers first using switch. On first floor, we will place 25 computers, and we have connected these 25 computers using Fibre cable for LAN (Local Area Network). Also we need 3 printers to share on three floors and we connect 1 printer on each floor. We connect all 25 computers and 1 printer with switch. This process has to be repeated on three floors, and then we have to connect them with router. Server computers will be connected with router directly but through switch. When server is directly connected with router, it enables firewall implementation and sharing among the network with secure authentication. LAN is used to connect computers within local area and make a network between them. We use this network in this case to connect computers within the same building. After connecting them through LAN cable, we connect them to Switch. HUB is also called concentrator or multi station access unit (MAU). A normal hub contains 8 to 24 ports for the computers and other devices. It works as a multiple port repeater. It receives a digital signal and re amplifies or regenerates that signal. It then forwards the digital signal to all ports on the hub without looking at any data. Switch is also used for the same purpose as hub but it is more intelligent device. It operates at data link layer of OSI model. The biggest benefit of using switches instead of hubs is that each switch port has its own collision domain. Switch plays really an important role in network. Once they are connected with hub or switch, they will be connected with ROUTER. ROUTER ROUTER is a device which connects multiple networks using similar or different protocols. It manages the route between any two communication networks. IP address will remain the same because there is just one router and it will supply access to all four switches. Each Switch which is having 25 computers and 1 printer on three floors and third one is also having server computers on it will connect with switch which will lead to router. Each computer will have different IP but their ISP will be one only as this will be provided by service provider. After three sets of 75 computers and three printers connected with Switch which is connected to router, after this process we connect one more switch with router which has 3 server computers on it. One server would be file server or printer server, and one would be DHCP/Authentication/Certification server and DNS server. This server system would help in file or printer sharing along the network to protect the computers with firewall option and also to provide certification to computers for different task over the network. OSI OSI stands for Open System Interconnection. It is a set of protocols that allows any two different systems to communicate regardless of their underlying architectures. This physical connection of router with switch and computers comes in Physical Layer of OSI model. Physical layer relates the electrical, optical, mechanical and functional interface to the cable as it defines how the cable is attached to the network adaptor card. Connection of computers with Switch includes Data Link Layer of OSI model. It sends data frames from network later to physical layer. Router is supplying single IP address, and each computer has different IP address. This concept involves Network Layer of OSI model which is responsible for putting data segments into packets. Transport layer works after Network Layer which is responsible segmenting data. It ensures that packets are delivered free of errors with no loss. For implementation of Network especially of Internet cafe, some softwares have also been recommended. Cyber cafe management and installation of networking protocols like IPX, SPX and TCP/IP. This thing comes in Session Layer. The main purpose of session layer is to establish a connection through application running on two different computers. Presentation layer and Application layer are after session layer. Presentation layer is used to determine the format of exchanging the data among network. Application layer handles network access, control the flow and recover errors. Addressing Scheme: Addressing scheme plays an important role in network. TCP/IP, IPv4, IPv6 are essentials of Network scheme. They are normally set to default but they can be changed according to the requirements. Each network system must be identified as unique. This is done through MAC address of device. Each machine always has different IP address on the network. TCP/IP is known as transmission control protocol/Internet protocol. It is a technology that is used to manage the transmission of data by breaking it into packets. These packets travel through router. TCP/IP addressing scheme is used in implementation of this network. This network scheme is normally used for sharing of computers over the network and gives them internet access. IPv4 (Internet Protocol version 4) addressing scheme is really important in a network. The most important aspect of IPv4 is its size. It is most widely organized internet layer protocol. It is a connectionless protocol used for packet switching link layer. IPv4 can establish more than 256 connections. Its range starts from 0 255. This connection is really helpful in internet cafe setup. Normally IPv4 is set to default which detects IP automatically, but we can define IPv4 manually as well which can be allocated. Manual configuration can change IP of the system for some purposes as well. Sub-netting plays an important role in networking. It is a subdivision of an IP network or when the network is divided into several small networks. It results in logical division of an IP address. Subnetting an IP can be done for the various reasons which generally include different physical media, address space, security, control network traffic etc. Subnetting makes it easier to manage the smaller network as well. Subnet masks are also used with IP. Computer performs a bitwise logical AND operation between the address and subnet mask in order to find the Network Address or number. The general syntax for Subnetting is 255.255.255.0 There are generally three classes used for Subnet masks Class A: 255.0.0.0 Class B: 255.255.0.0 Class C: 255.255.255.0 Calculations of Network Subnetting: We have to implement a network with single registered IP which is given by our service provider. 195.5.20.0 This is known an IP address. The default subnet mask for this one would be 255.255.255.0 We have to implement 4 networks and they should be provided with different IP addresses. We use the following steps to find out the network and host computers over the network and range as well 195.5.20.0 255.255.255.0 We use 8 bits for binary written form. 255.255.255.0 = 11111111.11111111.11111111.00000000 This is default Subnet of network We have to implement four networks in a network, so we will do with 4 in binary 2 4 2 2 0 1 0 4 Decimal = 100 binary We will take 3 bits as a result of binary conversion from bit scale. The bit scale helps in implementing a network more easily 128 64 32 16 8 4 2 1 We will take 3 bits for new subnet mask and new Subnet mask will be 11111111.11111111.11111111.11100000 This will be equal to 255.255.255.224 Our new IP range will be 195.5.20.0 195.5.20.31 195.5.20.32 195.5.20.63 195.5.20.64 195.5.20.95 195.5.20.96 195.5.20.127 This is our range of new 4 Networks made by Single registered IP. Network Layout Diagram: Analysis and Synthesis: This research is a conceptual base in which most of the prediction has also been used apart from research on different structures and equipments used in this setup. A concept has been taken from http://www.ccautosoft.com/2011/03/connecting-all-hardwares-in-internet-cafe/ which shows the setup for the internet cafe. This is was quite helpful in equipment structure. This project has been designed to improve the performance of internet cafà © setup with compare to new technology as of library or lab network. Conclusion: This has been concluded from this project that it is reliable and secure network. It can easily give access to all the computers equally. There is less risk of virus spreading over the network as secure switches have been used which gives the high profile for Firewall and other activities. This project uses the latest technology routers and switches which enables the network to communicate more effectively. Also this project is cost effective, and it allows less cost to be spent over the network. Computers have been used with moderate specifications which are compatible to run over network properly.

Victor Frankenstein Essay -- Literary Analysis, Mary Shelley

The break of dawn the sun is shining, over the horizon and the heart is slowly letting in the sunlight. As the sunlight penetrates, through the soul, sun paves a way to joy, peace, and a happy life. As human beings, one thrives to succeed in life, one thrives to come to the point where we may look upon one’s life and remember all the superior times we owned, one thrives to be someone, someone great, and one thrives to accomplish this with our own ability. In further analogy, Willy yearned to succeed as so did Biff, Frankenstein, and the creature Frankenstein had created. To look upon one’s life without any regrets is a hard task to accomplish. In the same way, the characters mentioned are all uniquely different but yet the same in purpose: trying to succeed. The main character of Frankenstein and Death of a Salesman seize similar qualities; yearning to succeed in life, acquire a unique relationship with another key figure in the plot line, and possessing the qualities o f a tragic hero. Generally, Victor Frankenstein experiences a peaceful childhood in Switzerland, Victor Frankenstein experiences an idyllic childhood in Switzerland; surrounded by a loving family and accompanied by his cousin Elizabeth. Victor is fascinated by all of the books he reads about science. After the death of his mother, his first murderous experience was when he attended the University of Germany where he applied his newfound knowledge and created a human being, (a.k.a the monster) of enormous size and strength. When his creation becomes awakens Frankenstein, is so horrified by his creation that he falls into an illness, lasting for months. While he is still sick, the creature leads himself into the woods and deliberately does what his brainpower appr... ...ero. The possession of the tragic flaw ultimately defines them as modern tragic heroes. The main character of Frankenstein and Death of a Salesman possess similar qualities; longing to achieve something at life, acquire an exclusive relationship with another key figure in the plot line, and possessing the persona of a tragic hero. The main characters both create a purpose for their life that they do not ultimately follow through. Victor is on the pursuit to find his creature. On the other hand, Willy is trying to live out the American Dream through wrongs means of doing so. They both have a key relationship in the story: Frankenstein is to the creature as Willy is to Biff. Willy and Frankenstein both are classified as tragic heroes because they both possess a tragic flaw. Willy covets the wrong dream, as opposed to Victor who is over-reaching to create life.

Internet Marketing Essay

For my assignment I work for an internet consumer magazine, I have been asked to produce an article and will then analysis the benefits of internet marketing to customers. Customers have gained massively from the use of the internet. As the number of users of the internet increases more and more customers will shop online. Listed below are some of the benefits of the internet for the customer. Customers stay updated Customers are kept updated with product information either via the website or emails. With the internet now becoming mobile, through 3G technology and Wi-Fi, customers can be kept updated almost in real time. Customers can compare online One of the greatest advantages for the customer is that they can compare products or services they wish to purchase from the comfort of their own homes. Instead of visiting a number of different retail outlets, the user simply has to open different window tabs to compare prices or features of the product/service they wish to purchase. Many retailing websites offer the facility where different products they sell can now be easily compared. There is also price comparison websites that customers can use to get the best possible price for their products. Clear product information for the customer Websites offer clear product information on the product or service. There is little chance of misinterpretation or mishearing what the sales person said. Transparent pricing Pricing online is very clear and transparent for the customer. Customers can take advantages of pricing that may change regularly or take advantages of special offers that last for a limited period. Track your purchase Consumers have to pay for their product /service before they receive it. It is important that consumers feel reassured when this happens. Many websites allow consumers to track their purchase from order, dispatch to transportation before delivery to their home address. Again this reassures the consumer and makes them feel that they are obtaining a good service online. Reduction in personal carbon footprint. As consumer spend more time shopping online and use their cars less. Their personal carbon footprint is reduced. 24/7 Shopping There is no time restriction on when a consumer can shop online. Many online sales now start at midnight on a particular day encouraging customers to shop all hours of the day.

Alternative Lifestyles in Krakauers Into the Wild and...

After reading Krakauer and Thoreau I have learned about an alternative lifestyle that was brought to light by both of these writers. Both of these men write about a life of minimalism and the act of self-reliance. Through Thoreaus writing about his own life in Walden and his essay Civil Disobedience and the story of Chris McCandless told by Krakauer in his book Into the Wild we learn about two similar but at times very different viewpoints on the subject. I would like to compare the two lifestyles and show how different the lifestyle of McCandless was to Thoreau and ultimately prove that the actions of McCandless were careless and eventually led to his death in the wilderness of Alaska. When starting to compare both of the†¦show more content†¦Thoreau was a man that loved nature. Even before he started his experiment he was a man of nature and lived his life aware of all his surroundings. He also was very into politics and the economy. Along with being know for his ti me spent at Walden, he is also know for a night spent in jail during the two years he was in the woods. In real time, the American philosopher and naturalist spent exactly two years, two months and two days (1845-1847) living in relative solitude at Walden Pond on the outskirts of his native Concord, Massachusetts. In between two of these 794 days, Thoreau spent only one night, albeit a historic one, in jail rather then pay taxes which he said supported slavery and unjust war(Conrad 137). He was a very intelligent man that had strong beliefs and did the things he did with strong reasoning and thought. You will find that these characteristics will be the ones that separate him greatly from McCandless. Jon Krakauer tells the life of Chris McCandless in the bestselling book Into the wild. The book documents McCandless life through personal journals and interviews of the many people he came into contact with throughout his travels. His life comes off of one that was carefree, giv ing and lived to the most natural of lives somebody could live. Krakauer does a wonderful job of tugging at the heartstrings of his readers and painting the beautiful picture that is Chris McCandless.

On one hand, Chris McCandless (Into The Wild), Timothy Treadwell (Grizzly Man), and Thoreau are similar in several ways. All three men record some kind of documentation about their journey; McCandless and Thoreau keep journals while Treadwell keeps a video log. Also, all three forced themselves
