¶ … features of telecommunications networks, including key networking technologies. Cover the Open Systems Interconnection (OSI) model, including each logical layer.
The OSI layer covers the different layers and types of communication that occurs within a network. The layers, in order of complexity from greatest to lowest are application, presentation, session, transport, network, data link and physical. The physical layer is the actual transport medium like network cable and such while routers and switches address much of the middle layers while the "window" to the user is the application layer at the very top. Telecommoniciation networks, and this is something that will be answered more in-depth later in this report, are very computer driven and are in many ways indistinguishable from regular computer networks as phone and conventional internet networks are very much one and the same and this is especially true when speaking Voice over IP (VOIP) technologies and the like. Even so, more dated technology is still commonly used in the forms of phone switches, networks and the commonly known area code and regional prefix systems that have been around for decades.
2) Discuss whether telephone networks and computer networks will remain distinct in the future.
To finish the question that had its answer started in the answer to the first question, the difference and line between internet networks and phone networks is getting harder and harder to see. For example, there are software packages and suites like Skype, IP Agent and so forth that allow people to use computer applications to initiate, forward and track calls. Client service organizations now have technology that allowed a call to be recorded with direct sync to what a computer user is doing, accessing and using on their desktop as the call progresses. Then there is the aforementioned voice over IP (VOIP) technology whereby phone calls are transported via the Internet rather than in old school phone lines and phone numbers...
Network Design Network ABC NETWORK DESIGN A Comprehensive Proposal and Design for ABC Inc. Network Requirements Network Proposal Overview Telecommunication Overview Telecommunication Proposal Network Configuration Management Plan In order to meet the needs of the customers, ABC Inc. must insure that productivity is not hindered by the growth of the company. The employees at ABC Inc. must have a robust network so that customer service is not jeopardized. The accounting firm has grown from five to fifty employees
Networking Practical Networking in the Modern Business Environment Networking architecture is vital in the organisation of any business firm in today's globalised world. RFID, Cloud Computing, Intranet Network Architecture and Digital Rights Management (DRM) are major fields of endeavour that require the resources of companies. Increasingly, all aspects of an organisation are linked via the Internet and various other technologies in ways of connectivity that we did not even imagine before. Radio Frequency
Therefore, the suggestions forwarded would most definitely be different if the discussion had been about another country or another industry. But even so, there are some rules compulsory to be implemented, without which the organization will not retrieve the desired beneficial results. These general recommendations include: Clearly analyzing the features of the new market in order to get an idea of the product demand and the needs of the customers,
Network Implementation for Davis Networks Inc. In the proposal, effort is made to develop an affordable local LAN for Davis Networks Inc. The effort involves provision of wireless Internet connection to all individuals for their desktops and laptops from the current high speed connection they have at an affordable price (800 USD -- 1000 USD). Provision of the internet to the same location costs approximately 700 USD including all other expenses
wireless communication networks and all the mechanisms involved in making them effective. Our investigation explored the history and development vision of mobile networks. We found that there are two ways of providing communications services; through a system of wires, that allow the transmission and reception of information at the fixed points, and through wireless connections, that use electromagnetism to carry information from one place to another. We also discussed the
The transformation of networking from the past to our current day, as well as the trends for our future Websites (or digital channels as they were then called), were initially meant for connecting organizations with their clients. This was followed by the emergence of digital processes for supporting client interactions. Bigger digital ambitions implied establishing committed digital teams for managing their mobile and social channels (Atzori et.al 2010). For better utilizing vast
