This paper is to inform the reader of the benefits of DNS and DHCP within a network. DNS stands for “domain system name” These are the human readable web addresses we use every day. Unfortunately, computers do not understand human language and web addresses must be made readable to computers. This is where DNS comes into play. If you were to type in google.com in the address bar of your browser, google.com would appear. Computers use numerical IP addresses to translate “Google.com”. Google’s IP address is 173.194.39.78 and if you were to type this in the address bar the website would populate this way as well.

DHCP stands for “Dynamic Host Control Protocol” and is used to automatically assign IP addresses to authorized computers attempting a connection to the network. The way this works is that a computer attempting a connection will send a request to the DHCP server. The server receives and acknowledges the request. The server then sends the acknowledgment back to the user with a leased IP address. When it’s all said and done, the computer attempting to gain access should now be able to access the network.

Assigning IP addresses using DHCP is an easy thing to today. Unfortunately the more workstations you have on your computer, the more conscious you need to be about the IP’s assigned. When manually configuring these, it is possible to duplicate IP assignments, configuring the incorrect subnet mask, and incorrectly configuring other TCP/IP parameters. Small networks should have at least one DHCP server, while larger networks should have multiple implementations of DHCP. The benefit of this is that you can split the address space, while fault tolerance is provided. In conclusion, DHCP can benefit small and large networks as long as they are managed

...GVCs represent the significant unit of organization of international production, wherein ‘lead firms’, largely multinational corporations (MNCs), coordinate production across international borders through extensive networks of suppliers spread across large numbers of countries. This has resulted in a significant change in the structure of international trade, leading to a domination of what has been referred to as the ‘trade in tasks’, that is, trade is no longer characteristically undertaken in goods, but rather in particular production segments (cut make-trim (CMT) versus the design brand market) of a production chain. The ‘trade in tasks’, empirically measured in terms of trade in intermediate goods, reflect this phenomenon, and the gains accruing to low- and middle-income countries in trade involvement are clearly seen here, with their share constituting more than 35 percent of the world’s intermediate goods trade during the latter half of the 2000s (Milberg 2004). However, it has also been noted extensively that, despite increases in export shares, involvement in GVC-coordinated activities has often not led to any significant increase in value added from those activities over previous commodity-based export regimes because lead firms in global production networks...

...Windows 2008 Network Services A Network Administrator will need to be able to make recommendations about overhead costs that support the size, security needs and growth possibilities of an organization. One area that will impact the entire organization for years relates to using/installing Domain Name System (DNS) and Dynamic Host Configuration Protocol (DHCP). DNS and DHCP services can be set up in an office by installing the correct equipment or through the ISP that the organization is using. Knowing what is best for the organization should be based on their current size and equipment needs. A small office with only 2 computers would not require new equipment to be installed. In this size office I would recommend statically assigning the IP addresses to the two computers and using the DNS that is on the ISP network. For an office a little bigger, with 5 computers, I would recommend that they install a router/hub in-one device which can also act as a DHCP server. These all-in-one devices are typically less than $200, will add firewall protection and have ports to connect the computers via an Ethernet connection which will allow better internet access. I would still recommend that this office use the DNS on their ISP’s network. For a larger organization with over 25 computers, I would recommend that they install a Server which will have both DNS & DHCP options. With the size of this organization, having the DNS & DHCP on site will allow for quicker response...

Denial of Service Attacks in Network Security

...Denial of service attacks in Network security introduction and short history of DoS attacks: Denial of service attacks are one of the major threat to the modern computer networks.It has been said that first DDoS attack was launched in 1999 against the IRC server of university of minnesota which affected 227 systems and server was down for several days.Another DoS attack was documented in the week of feb 7 2000.A 15 year old canadian hacker named “mafiaboy” performed a series of DoS attack against some sites like ebay and amazon.Companies suffered from 1.7 billion of damage.After that it became the best way of hacking among cybercriminals. People used to perform these attacks for profits.Hackers will follow the procedures like mafiaboy and ask for the money.In 2005 ,it became more easy to implement those attacks ,a boy of 18-yr old named Farid Essabar developed a worm called MyTob which used to open a backdoor in Ms windows hosts and connect to the remote IRC server.The computer then used to wait for the commands from the servers.Farid was arrested for distributing the worm.This was surely not the last case.DDoS attacks were used to attack and money extortion. As name suggests Denial of Service aka DoS, it’s main objective is to make the system to deny the legitimate service requests. Basically DoS attacks are performed by exhausting the resources of the computer like processing power,network bandwidth,TCP connection and service buffers,CPU cycles and so on.Hackers actually...

Unit 1 - Assignment 1 - Windows 2008 Network Services

...Unit 1 - Assignment 1 - Windows 2008 Network Services If you have a routed local area network and high-speed links that are fairly reliable, you might be able to use one DNS server for a larger, multiple sub-netted network area. If you have a high number of client nodes on a single subnet design, you might want to add more than one DNS server to the subnet to provide backup and failover if the preferred DNS server stops responding. When determining the number of DNS servers you need to use, assess the effect of zone transfers and DNS query traffic on slower links in your network. Although DNS is designed to help reduce broadcast traffic between local subnets, it does create some traffic between servers and clients that should be reviewed, particularly when used in complexly routed LAN or WAN environments. Consider the effects of zone transfer over slower speed links, like those typically used for a wide area network (WAN) connection. Although the DNS Server service supports incremental zone transfers and DNS clients and servers can cache recently used names, traffic considerations are sometimes still an issue, particularly when DHCP leases are shortened and, as a result, dynamic updates in DNS are performed more frequently. One option for dealing with remote locations on WAN links is to set up a DNS server at these locations to provide caching-only DNS service. With most installations, you should have at least two server computers hosting each of your DNS zones for fault tolerance...

Simulation Study on Service Based Adaptive Qos Framework for Vehicular Adhoc Network- Redem

...Vehicular Adhoc Network (VANET) is an outgrowth of Mobile Adhoc Network (MANET), in which the mobile vehicles on road and the stationary roadside units (RSU) constitutes the nodes and communicate with each other on the fly (Fig. 1); Vehicle to Vehicle (V2V) and Vehicle to Roadside Unit (V2R). VANET can be categorised under hybrid architecture that consists of both infrastructure and infrastructure less features. VANET nodes are capable of self organising and managing the information in a distributed fashion with or without any centralised authority. Road Side Units (RSU) supported by DSRC standard [2] acts as gateways or fixed access points to vehicles in mobility and provides interim connectivity to vehicles. One of the major advantages of VANETs over MANETs is the unlimited battery power generated on the fly. VANET plays a major role in defining safety measures by streaming communication between vehicles, infotainment and telematics. In any generic network phenomena the concept of routing and its characteristics are highly linked with Quality of Service (QoS). The United Nations Consultative Committee for International Telephony and Telegraphy (CCITT) Recommendation E.800 has defined QoS as: “The collective effect of service performance which determines the degree of satisfaction of a user of the service”. The major concern of VANET routing is that whether the performance can satisfy the throughput and delay requirements of such media streaming applications. Unavailability...

Windows 2008 Network Services

...Unit 1 Assignment 1 windows 2008 network services Short for Dynamic Host Configuration Protocol, a protocol for assigning dynamic IP addresses to devices on a network. With dynamic addressing, a device can have a different IP address every time it connects to the network. In some systems, the device's IP address can even change while it is still connected. DHCP also supports a mix of static and dynamic IP addresses. Dynamic addressing simplifies network administration because the software keeps track of IP addresses rather than requiring an administrator to manage the task. This means that a new computer can be added to a network without the hassle of manually assigning it a unique IP address. Many ISPs use dynamic IP addressing for dial-up users. Short for Domain Name System (or Service or Server), an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.105.232.4. The DNS system is, in fact, its own network. If one DNS server doesn't know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned. DHCP would be better used if you were going to set up a large network of computers I’d say about 25 or more...

Social Network

...History The potential for computer networking to facilitate newly improved forms of computer-mediated social interaction was suggested early on.[8] Efforts to support social networks via computer-mediated communication were made in many early online services, including Usenet[9], ARPANET, LISTSERV, and bulletin board services (BBS). Many prototypical features of social networking sites were also present in online services such as America Online, Prodigy, CompuServe, and The WELL[10]. Early social networking on the World Wide Web began in the form of generalized online communities such as Theglobe.com (1995),[11] Geocities (1994) and Tripod.com (1995). Many of these early communities focused on bringing people together to interact with each other through chat rooms, and encouraged users to share personal information and ideas via personal webpages by providing easy-to-use publishing tools and free or inexpensive webspace. Some communities - such as Classmates.com - took a different approach by simply having people link to each other via email addresses. In the late 1990s, user profiles became a central feature of social networking sites, allowing users to compile lists of "friends" and search for other users with similar interests. New social networking methods were developed by the end of the 1990s, and many sites began to develop more advanced features for users to find and manage friends.[12] This newer generation of social networking sites began to flourish with the emergence...

...social networks are one of the most important speaking topics between peoples and the popularity of social networks is increasing day to day. In order to have a fair point of view in case of the social networks we have to look for both advantages and disadvantages equally. For example using the social networks in the work environment could have some concerns and also some benefits for employers. The good impact would be in the social performance between the staff and the negative impact is personal using of the social network websites. But this is undeniable that all these indications show the real model of the modern work environment and their effective impacts on the business world. As an important positive effect on the business environment we can consider the social networks as a tool of communication between management and employees. (Breslin, T. (2009, September). When social networking enters the workplace) Some of the most popular Social Network Websites There are more than two hundred social network websites which they are created for different purposes for different kind of users but here we can point out to two major social network sites which are more popular.
