Remote Access Services (RAS) refers to any combination of hardware and software to enable remote access tools or information that normally resides on a network of IT devices. Remote Access Service (RAS) connects a client to a host computer, known as a remote access server. To use RAS from a remote node, you need a RAS client program or any PPP client software. Most remote control programs work with RAS. PPP is a set of industry-standard authentication and framing protocols that enable remote access.
History
The term was originally coined by Microsoft when it refers to its integrated Windows NT remote access tools. RAS is a service provided by Windows NT that allows most services that would be available on a network to be accessed through a modem link. The service includes support for dial-up and logon, it has the same network interface as normal (though slightly slower) network drivers. RAS works with several major network protocols, including TCP / IP, IPX, and NBF. It is not necessary to run Windows NT on the client; There are client versions for other Windows operating systems. RAS allows users to log on to an NT-based LAN using a modem, an X.25 connection, or a WAN link.
Beginning in the mid-1990s, several manufacturers like U.S. Robotics produced "modem terminal servers." Instead of having RS-232 ports, these would directly incorporate an analog modem. These devices were commonly used by Internet service providers to allow telephone access for the consumer. Modern versions interface to an ISDN PRI instead of having analog modem ports.
RAS are now commonly used for online technical support for personal computers. The first instance of this was in 1987 in the UK, provided by a company called Jade Technologies. This used the MS-DOS-based program called PC Anywhere to link directly to MS-DOS and Windows with Windows. The company had been providing RAS support for Unix-based enterprise systems for 2 years prior to this.
Benefits of Remote Access
• Improved productivity - staff can work from home, hotels or anywhere
Where there is Internet access. It's easy to access vital information such as documents, email and even applications that reside on the company's server. People no longer have to wait to get into their office before they can access and read emails.
• Staff can continue to work on projects from home.
• Greater profitability. People can respond to customers' emails and requests quickly, regardless of whether they are traveling or not. This, as a result, can improve sales performance and customer service.
• Quality of life. It allows people who perhaps live a long way from their office to be able to maximize their days without necessarily spending hours traveling to and from the office. People generally appreciate the flexibility that remote access systems give them.
• It also helps attract talented workers who may work too far from an organization's headquarters to travel daily.
• Improved retention of valued employees. For example, a person who needs to move to another area can still continue to work for the company because distance is no longer a problem.
• Improved efficiency. Staff can keep in touch with your company's email and developments, regardless of location and time zones.
• IT systems can be managed remotely. This allows the experts to access the computers to solve possible technical problems without having to be on the site.
• Eliminates the need to synchronize files and other data between a person's laptop and the desktop PC.
• Lower office expenses. Remote access systems allow companies to potentially use smaller offices than if all employees had to be in the office at the same time every day.
• It is not necessary to carry a laptop to access a network. It is possible to gain access to an organization's network through any third party PC or other device so it refuses to have to carry a laptop at all times.
