of development of the networking field
Computer network what we know today was
born with the name called Arpanet in between 1960 and 1970. Before that there
were network designed for mainly connecting the terminals and remote work to
the entire unit. The main motto of networking was they can share same resource
of information the both peer at the same time was fundamental design of the
The other strong emphasis of the ARPANET
work was its reliance on the then novel technique of packet switching to
efficiently share communication resources among” busty” users,
instead of the more traditional message or circuit switching.
Introduction National Physical Laboratory
Network in England and the Ethernet system at Xerox PARC in the USA. Some of these
projects focused more heavily on the potential for high-speed local networks
such as the early 3-Mbps Ethernet. Satellite and radio channels for mobile
users were also a topic of growing interest.
By 1973 it was clear to the networking
vanguard that another protocol layer needed to be inserted into the protocol
hierarchy to accommodate the interconnection of diverse types of individual
networks. Cerf and Kahn published their seminal paper describing such a scheme,
and development of the new Internet Protocol (IP) and Transmission Control
Protocol (TCP) to jointly replace the NCP began. Similar work was being pursued
by other groups meeting in the newly formed IFIP WG 6.1, called the
Internetwork Working Group.
By the late 1970s, a new major influence
was emerging in the computer network community. The computer manufacturers
realized that multivendor systems could no longer be avoided, and began to take
action to satisfy the growing user demand for interoperability. Working through
their traditional international body, the ISO, a new group was created to
develop standards in the networking area. Their initial charter was to define
an explicit “architecture” for “Open Systems
And this is how network had taken place
in the era of technology.
The recent trends are in computer
technology are as follow
The growing popularity of cloud computing and cloud storage.
Voice, email, SMS, Ring
tones, Push, Gaming, Pictures, Instant Messaging ,Music, Video, Location,
Remote monitoring, M-commerce , Video telephony, remote enterprise
applications, remote management, Multiparty collaboration.
Improvements to mobile (cellular) network
infrastructure – both deployments of 4G and also enhancements to older 3G
networks – that have enabled people in developed areas who can afford it to use
their Smartphone as mobile televisions and video broadcasting systems.
