As stated by the website howstuffworks.com (What is an IP address?), ‘An IP address is assigned to every device connected to the Internet. This is a 32 bit protocol, as it consists of 4 binary octets’. However they are usually written in decimal form for ease of use. The maximum decimal number allowed by one octet is 255 (or 11111111 in binary). The total number of unique possibilities of 4 octets would therefore be 256^4, roughly 4.3 billion addresses.
Demand for IP addresses is increasing due to reasons such as low cost computers, advancement in technology, and improvements in accessibility. Personal computers have been subject to a dramatic decrease in price over the last 10 years, allowing them to be bought by more households – 70% had at least one in 2007, compared with 49% in 2001/2 (statistics.gov.uk). This was just in the UK, however the same thing has happened globally.
Advancement in technology has enabled mobile telephones to connect to the Internet, thus dramatically increasing the number of devices connecting to it. Internet access via mobile phones has risen as 3G networks allow a decent download speed of up to 14Mbps, compared to 2G with 114Kbps.
Accessibility to computers has also been advanced, with the general public being proficient with them, as opposed to a specialist. This is due to the development of GUI’s (Graphical User Interfaces). GUI’s mean one doesn’t have to type in commands to the computer using a terminal, rather one can click a button instead, which is practical as it saves having to learn a new language. Disabled people can also use computers, as specialist software ships with the recent operating systems, such as a narrator, screen magnifier and speech recognition software.

IPv6-the next version of IP, already implemented in some of the newest Internet ready devices. IPSEC and congestion control (ECN) functionality are already put into service. Increased address space will decrease the effectiveness of attacks scanning for vulnerable machines.

Individuals who are deaf or are hearing impaired are faced with many problems in today’s world. There are so many tasks and activities that are done today that deaf or hearing impaired people may have difficulty doing because of there handicap. There handicap used to stop them or inhibit them from doing something that they are interested in or there friends and neighbors would do. However in today there are new and different technologies, that help the deaf and hearing impaired in the activities in which they want to participate in which is hard for them to take part in because of there handicap. Technology is used to help with everyday tasks in the lives of deaf and hearing impaired individuals. With out this new technology which is being invented everyday, deaf and hearing impaired people may be considered to have a handicap which prevents them from certain activities, but this is not the case anymore, now these people just have different obstacles which through the use of technology they are learning to over come. They can do anything that regular normal range of hearing individuals can do, due to the new technology being invented everyday.

The increasing use of NAT comes from a number of factors. The major factor is that there is a world shortage of IP addresses. As the Internet has grown, assigning perfectly good network addresses to private networks came to be seen as a waste. Under the Network Address Translation (NAT) standard, certain IP addresses were set aside for reuse by private networks. In addition to reducing the number of IPv4 addresses needed, NAT also provides a layer of obscurity for the private network, because all hosts outside of the private network observe communication through the one shared IP address. NAT is not the same thing as a firewall or a proxy server, but it does contribute to security. NAT also succeeds in the ease and flexibility of network administration. It can divide a large network into several smaller ones by exposing only one IP address to the outside, which means that computers can be added, removed, or have their addresses changed without impacting external networks. Other benefits include Protocol-level protection, Automatic client computer configuration control, and Packet level filtering and routing.
The history of the internet shows that the internet is not a new medium. The internet was initially created in the 1960's to as a way for the United States to stay connected in case of a nuclear fallout due to the possible consequences of the Cold War. F...
SUBNET MASK: In this case, the subnet mask would be 255.255.255.0. A subnet mask is created simply by filling all NET address bits with 1 and the HOST bits with 0. (11111111 = 255). There are 4 "Classes" on the Internet, which are the standard Subnets. *Class A: "0" + 7 net bits + 24 host bits, hosts 0.0.0.0 to 126.255.255.255 Net IDs: 0 0000000 to 0 1111111 (which is 127 => 127.0.0.0 reserved for local loopback)
The modern Internet began as a U.S. Department of Defense (DoD) funded experiment to interconnect DoD-funded research sites in the U.S. In December 1968, the Advanced Research Projects Agency (ARPA) awarded a contract to design and deploy a packet switching network to Bolt Beranek and Newman (BBN). In September 1969, the first node of the ARPANET was installed at UCLA. With four n...
Since the internet came about in the late 1900’s it has been rapidly growing in the popularity
The Internet’s beginnings stemmed from the US Department of Defenses Advanced Research Projects Agency (ARPA). ARPNET, developed by ARPA in 1969, was the first stable link between multiple computers. This occurred ten years after the first conceptual network architectural models which were initiated by Paul Baran and Donald Davies (History, 2014, p. 1, para 3). During the 1960’s and 1970’s ARPA was a primary source of funding for
3G smartphone can conduct high speed data transfer rate by accessing 3G cell phone technology and its mean browsing, streaming and downloading speed is extremely high. 3G also support for the phone to using video calls, watching television, and surfing internet without manually connecting internet and no need to stay in the nearby wireless network. 3G technology are more functional and had been overtaken 2G in any aspect in most location. User will find he 3G network are more faster and advance further than 2G.

But how is this achieved? The range of special needs covers a very wide spectrum. It will be necessary therefore to examine how ICT can support the various needs. Standard equipment is often suitable for children with SEN. the settings of the computer can be changes to make it more computer friendly.
