I  Concepts & Terms Required - Chapter 0111 1 III  Individual Dial Up Remote Access

Remote access is now a standard computing activity for a corporation’s ‘road warrior’ employees as well as the SOHO (Small Office Home Office). Why?

Just as many corporate staff can’t go anywhere without their cell phone, many need access to their email from almost any location at almost any time. Also many benefit from access to their corporate intranet applications such as inventory tracking programs as well as product documentation. Companies are increasingly making their business applications and data available over the web, just like many Internet applications (shopping carts and product catalogs at e-commerce sites, for example). The stage has been set to make the browser the default interface, eliminating the choice of the operating system of the computer or terminal. Also, as higher speed remote access technologies become available, users are taking advantage of “remote desktop” services that let them access their office PC from the road or home.

Also, in the past 5 years, Internet access has become a more and more desirable commodity to consumers, opening up a new market for Internet Service Providers. These organizations purchase high-bandwidth WAN lines to the Internet and are in the business of reselling access and support services to consumers and businesses.

The Internet has changed the way the world communicates and with this, the concepts of distance and time. Communications companies are battling for clients across industries previously separated from each other, such as, Cable and Phone companies. We’ll see this when we look at remote access alternatives.
