Broadband Internet access, often shortened to just broadband, is a high data rate Internet access—typically contrasted with dial-up access using a 56k modem.
Dial-up modems are limited to a bitrate of less than 56 kbit/s (kilobits per second) and require the full use of a telephone line—whereas broadband technologies supply more than double this rate and generally without disrupting telephone use.
Although various minimum bandwidths have been used in definitions of broadband, ranging up from 64 kbit/s up to 2.0 Mbit/s, the 2006 OECD report is typical by defining broadband as having download data transfer rates equal to or faster than 256 kbit/s, while the United States (US) Federal Communications Commission (FCC) as of 2009, defines "Basic Broadband" as data transmission speeds exceeding 768 kilobits per second (Kbps), or 768,000 bits per second, in at least one direction: downstream (from the Internet to the user’s computer) or upstream (from the user’s computer to the Internet). The trend is to raise the threshold of the broadband definition as the marketplace rolls out faster services.
There are many different technologies that enable broadband connection speeds. The most mainstream of these include fiber, cable, DSL, mobile broadband, WiMax, and satellite (see descriptions below).…...

Meeting Human Services Challenges with Technology

...Meeting Human Services Challenges with Technology Gina Sharra BSHS-351 January, 24th, 2011 Nate Hooper Meeting Human Services Challenges with Technology Technology has grown so much in the last decade that it is something that really should be used in the human services organizations today. It can help any of the organizations to not only grow with the demands that need to be met in human services, but it can also help the many services that are already being used or help to implement new technology uses that are not being used at this time for instance updating their systems. Technology can be used in many ways to benefit human services businesses, organizations as well as the non-profit services. There are so many different software’s that can be used to upgrade systems, add in systems that are old-school in which it will not only benefit these places in time management, privacy, HIPPA laws and in many other areas. One challenge for human services non-profit organization is it needs the proper tools to be able to provide its community with the services that are needed. But if they do not have the tools to get the information out into the community on what services they do provide than the community not only has no idea about this organization and what they provide, but the organization actually looses too because they themselves have no clientele. The different types of strategies that can help in this particular situation would be to add different ways for......

Advantage of Broadband

...Question Number 1 What is Broadband ? The term broadband refers to a telecommunications signal or the marketing term for wireless Internet access through a portable modem , mobile phone or other mobile device. Mobile broadband, also referred to as WWAN (for Wireless Wide Area Network) On the other hand , broadband services provides higher-speed of data transmission. It allows more content to be carried through the transmission “pipeline.” What is WAP ? WAP stands for Wireless Application Protocol . Its a technical standard for accessing information over a mobile wireless network. A WAP browser is a web browser for mobile devices such as mobile phones that uses the protocol. Advantages of Broadband compared to WAP 1. Connection speed is up to 100 times faster than dialup connection. You can download pictures files, software in seconds or minutes instead of hours. Online gaming is only possible using a broadband internet access. 2. It does not affect the phone line. For DSL internet access, you can use the same phone line for both voice/fax and data transmission. For cable internet access, you are connected to the internet via the cable network. In either case, your phone line is not occupied while you are connected to the internet. 3. It is convenient because the internet connection is always on. 4. You don't need to dial an access number and risk getting a busy signal. 5. Broadband internet offers unlimited access and you won't be charged based...

Broadband Technologies

...INTRODUCTION Broadband is often called high-speed internet, because it usually has a high rate of data in general, any connection to the customer of 256 kbit/s (0.256 Mbit/s) or more is considered broadband internet. The international Telecommunication Union Standardization Sector (ITU-t) recommendation 1.113 has defined broadband as a transmission capacity that is faster than primary rate ISDN, at 1.5 to 2 Mbit/s. The FCC definition of broadband is 200 kbit/s (0.2 Mbit/s) in one direction, and advanced broadband is at least 200 kbit/s in both directions. The OECD has defined broadband as 256 kbit/s in at least one direction and this bit rate is the most common baseline that is marketed as “broadband” around the world. There is no specific bitrate defined by the industry, however, and “broadband” can mean lower-bitrate transmission methods. Some Internet Service Providers (ISPs) use this to advantage, in marketing lower-bitrate connections as broadband. Technology The standard technology in most areas is DSL, followed by cable modem. Newer technologies for twisted pair phone lines such as VSDL and pushing fiber optic connections close to the subscriber in both telephone and cable plants are opening up the possibility of higher performance for streaming data, such as audio and video streams. There are now many streaming audio services, and several streaming video services. In a few of the many areas not served by cable or ADSL. ISDN is an older telephone data service that......

...communications technology Information and communications technology (ICT) is often used as an extended synonym for information technology (IT), but is a more specific term that stresses the role of unified communications and the integration of telecommunications (telephone lines and wireless signals), computers as well as necessary enterprise software, middleware, storage, and audio-visual systems, which enable users to access, store, transmit, and manipulate information. The term ICT is also used to refer to the convergence of audio-visual and telephone networks with computer networks through a single cabling or link system. There are large economic incentives (huge cost savings due to elimination of the telephone network) to merge the telephone network with the computer network system using a single unified system of cabling, signal distribution and management. Information and communication technology expenditure (% of GDP) in Pakistan was reported at 4.37 in 2008, according to the World Bank. Information and communications technology expenditures include computer hardware (computers, storage devices, printers, and other peripherals); computer software (operating systems, programming tools, utilities, applications, and internal software development); computer services (information technology consulting, computer and network systems integration, Web hosting, data processing services, and other services); and communications services (voice and data communications......

Bshs352 Technology Solutions for Human Services

...Technology Solutions for Human Services Student Name BSHS/352 March 18, 2012 Teacher Name Technology Solutions for Human Services The human services industry is subject to several barriers that can hamper its efficiency and service. The abundance of technological advances can assist in removing these barriers. This paper will cover a discussion regarding three barriers to services, planning, funding, or empowerment in a specific aspect of human services. The purpose is to discover how community development helps address these barriers. A discussion will take place concerning how one could use applications of technology to overcome the barriers. One can transmit the processing, storing, and converting of necessary information securely and safely via technological methods. An additional benefit is the cost savings associated with using technology. To establish an information technology network for human services, organizations must establish an information infrastructure that will support their day-to-day operations. Barriers – Elderly Population The first barrier is the elderly population. Because of the rising elderly population, providing the necessary services to this population can be challenging because the mental and physical abilities decline. The elderly population consisting of individuals born between the years 1946 and 1964, also known as baby boomers, are a consistently growing population requiring human services resources (U.S. Census Bureau, 2012)....
