goldgroup.co.uk Internet enabled mobile usage starts peaking as
Telecommunication infrastructure becomes more affordable
Faster with better infrastructure Instant messaging (IM) is generating five
billion messages a day Over 162 million Top Level Domain Names
(TLDs) were registered up until the end of the
first quarter of 2008 According to Nielsen Online, 85% of US consumers have made an online purchase in the last 6 months The Internet now has 1.5 billion users and there are over 100 billion live web pages and rising.

Internet Networking moving towards Web 3.0
The computer generates new information rather than humans
Information viewed on web organized according to individual preferences Protocols The most significant additions since TCP/IP were: Border Gateway Protocol (BGP)

Domain Name System (DNS) protocols

Multicasting, real time protocol (RTP and RTCP)

Email protocols ( such as POP3, IMAP and SMTP)

Remote login protocols (TELNET)

File transfer protocol (FTP)

World Wide Web protocols
(notably HTTP, SSL, HTML, XML and so on) Protocols The ability to carry compressed voice and video is a major step forward

"Quality of service" protocols such as Multi-protocol Label Switching (MPLS)

Allow packets of information to be given different priorities so that the urgent ones can be delivered quicker

Telephony is moving ahead with Session Initiation Protocol (SIP) and many methods for digitizing and packeting voice Example: Skype Calls A computer network, or simply a network, is a collection of computers and other hardware devices (unique identity) interconnected by communication channels that allow sharing of resources and information. Definition Networks may be classified into a wide variety of characteristics Network Properties Network medium (Communication Channels) Network PROTOCOL Scale of Network Organizational scope of Network Network Topology Network hardware components Network performance medium used to transport the data
communications protocol used
organizational scope Facilitate communications
Permit sharing of files, data, and other types of information
Share network and computing resources Wired technologies.
Twisted pair wire
Coaxial cable
Optical fiber

Wireless technologies
Terrestrial microwave
Communications satellites
Radio and spread spectrum technologies (Wireless LANs)
Infrared communication Ethernet
Internet Protocol Suite Ethernet
Internet Protocol Suite Intranets and extranets
Internet BUS
MESH Network interface cards
Repeaters and hubs
Firewalls Network performance is synonymous with the grade of service
The number of rejected calls is a measure of how well the network is performing under heavy traffic loads
Other types of performance measures can include noise, echo, data throughput, connect time, modulation technique and so on
It is very important that the network should be optimally designed in order to achieve the best performance of network Network security Network security consists of the provisions and policies adopted by the network administrator
To prevent and monitor unauthorized access, misuse of the computer network and network-accessible resources Issues/Areas of Concern Bandwidth
IPv4 issues- Running out of IP addresses Futuristic Plans Internet2 & IPv6
High-speed transmission technologies
Broadcast transmission or enhancements to radio and television
Wireless broadband technologies
Gigabit Ethernet and Bluetooth wireless technology 2012 Third International Conference
on the Network of the Future (NoF 2012) New generation Internet, Post IP
User-centric networking and services
Content distribution networks
Self-management networks
Advances in cellular networks, Femtocell Networks
New approaches in wireless networks
Broadband Access Technologies
Cloud computing & Network virtualization Computer networking is considered a sub-discipline of the following:
electrical engineering,
computer science,
information technology
since it relies upon the theoretical and practical application of these disciplines and so it has tremendous scope and enormous potential

Today, computer networks are the core of modern communication
Scientific approach to network design can lead future development
Communication is the dominant organizational principle for the global economy
Age-old concept of the network is foundation to network communication
Network communication brought the massive growth of non market production Examples:
social networking sites
video sharing sites
hosted services
web applications

Beginning in 2002, new ideas for sharing and
exchanging content adhoc, such as Weblogs and RSS,
rapidly gained acceptance on the Web

This new model for information exchange, primarily featuring DIY user-edited and generated websites,
was coined Web 2.0
