The Internet and the World Wide Web –
The Internet and the World Wide Web often confused for one and other, but they are technically different.
The World Wide Web is an information-sharing tool that is built around the Internet. The Internet is a huge network made up of computers that are connected from all around the world. The Internet is a linked network of computer networks. (Bevan J. , 2010)
The Internet as network of networks –
The computers connected to the Internet aren’t connected to one huge computer which holds the services and information people require. The Internet is made up of sub-networks, some of the PCs hold the information people need and others just access the information. (Bevan J. , 2010)
Networking of computers –
Networking of computers can either be wired or wireless.
Wired networks are made up of PCs which are joined together using cables to connect them to the main hub. Wired networks offer businesses more security than wireless networks as well as being able to transfer data quicker.
Businesses can confine their network to just their members of staff, this is known as an intranet. This is the type of network used within College, with access to the Internet only being granted to College systems for educational purposes. If the College were to open their network and allow outsiders to use their network through giving them their password, this would be an extranet. Many cafes and restaurants use extranets to get customers into

Specialist Dental Services (SDS) has an existing Token ring infrastructural that uses IEEE 802.5 standard, meaning that it is a local area network in which all computers are liked in ring or start topology. A token (special bit pattern that travels around the circle, computer catches token to send a message, after attaching massage token is then continues traveling around the network) design is used to prevent collision of date between messages that were send at the same time. In the token ring infrastructure data rate transfer is 4 to 16 Mbps, with shielded and unshielded twisted-pair cabling of 1,2,3 IBM types to wire a token network. An Ethernet is different, since whenever any computer needs to send data, it does not need a token to send a message, any computer can send data at any time.

Encryption Security: Hard drive encryption: Without hard drive encryption if a hard drive becomes lost all the information on the hard drive would be viewable by plugging it into another computer. Particularly with a peer to peer network all the other computers on the network will be available if the hacker can access one. Wireless encryption: Wireless encryption is not as secure as a physical network, especially; if that wireless encryption is going to be the main way that strangers will be connecting to the network. All wireless protocols need to be at least WPA2 because of how many tools are out there and older models can be cracked.

Which is also known as the core layer campus backbone network. Essentially everyone on campus will have internet connectivity and connect to any server or printer located in any of the other buildings. The reason behind this is the data center is the home of the database servers as well as mail servers. Any devices for example printers connected to the network users will be able to have access to them. If users needed to access the network from home or other features we can add VPN to the network.

This means that within its subnetwork (the switch it is connected to) it would be able to connect to any other host connected to its local switch, as the subnet mask means it could connect to any host with the IP address 10.10.1.x, meaning that it will NOT go through the lab-a router if the IP is within that range. If we change the subnet mask of the circled subnet to /16, or 255.255.0.0, this would effectively disable the functionality of the host. This is because now the host will attempt to connect to all the hosts with 10.10.x.x within its own subnet and avoid using the lab-a router. This will break the connectivity of the circled host because all the other hosts that it could connect to are defined as 10.10.2.x, and the subnet mask of /16 means it will not go through the default gateway/router in order to access these

Physical Layout • Topologies; topology can be measured as a computer-generated nature or construction of a system. This shape does not agree to the real physical plan of the policies on the computer network. • Ring; basically in a ring system each device (workplace, waiter, and copier) is related to two other devices, this systems a ring for the signs to travel around. Each packet of data on the network trips in one way and each device collects each box in turn until the journey 's end device receives it.

With this layer it will be able to interconnect with networks and will decide how the layers can do this process. It will be able to can concentrate and determine how the data will get from one remote network to the computer. Also it will take care with devices which are local. This is mainly tasked to take care of is routing which allows data to be moved the data across the series of networks which are connected.

Often, many organisations use VPN to communicate across many locations. For example, a big company has many offices in different cities and they probably need to send data to the different places via the internet.

Moreover, each employee might have a VPN account with their business or company, so it 's help them to connect to their office computer from home or other places.

The Novel Fahrenheit 451 by Ray Bradbury, depicts a society in which conformity and obedience are of great value. Bradbury wanted to illustrate the overall importance of conformity in the novel through the idea and practice of censorship. Bradbury also wanted to illustrate the overall importance of reading and thinking freely in a time frame in which the value of reading was quickly diminishing through new technological advances. This dystopian society was successfully accomplishing this concept through book burning, the reason being that books have become such a fundamental part of human culture throughout the world and books enable knowledge and the lack of knowledge creates ignorance therefore making people easier to manipulate.
