An I/O tool can be either inner (set up in the computer case) or outer (set up away from case). Inner tools may be expansion cards placed in expansion slots on the motherboard, for example a network card, audio card, video capture card, and video card. Outer tools include keyboards, screens, mouse, printers, scanners, and digital cameras. You may connect an external tool to the system utilizing slots coming off the motherboard (serial, parallel, USB, IEEE 1394, etc), or a slot can be supplied by an expansion card.

But, for all these various tools, some fundamental rules apply to support each of them.
These rules are applied in several places and are summarized here to get a look at them. Look into these basic rules and ideas used when supporting I/O tools:

Each and every I/O tool is managed by some software items. If we set up a new I/O tool in our computer, for example a modem or printer, we should set up these tools and the drivers to manage these tools. These device drivers should be written for the OS you are using. For instance the keyboard, which is managed by the system BIOS or device drivers embedded in the OS. With regards to setting up or supporting a tool, the producer knows best. The I/O tools are set up prior to the device drivers which are set up in the computer since the device driver finds the device at the driver set up time (often when the I/O or peripheral device is initially plugged into the computer).
Some application software is often needed to make use these tools. For instance following the installation of the scanner and its device drivers, we may set up a Microsoft Word or Adobe Photoshop to utilize the scanner.
Computer
Issues with a tool can often be fixed by upgrading the device drivers. Generally device producers release updates to the device drivers. Upgrade the device drivers to fix issues with the devices or to add latest features. A few tools are expected to abide by the Energy Star standards. Energy Star systems and peripherals have the U.S. Green Star, showing that they meet particular energy preserving standards of the U.S. Environmental Protection Agency (EPA), occasionally named the Green Standards. Tools which can have the Green Star include computers, monitors, printers, copiers, and fax machines.

Therefore, briefly we can state that supporting an I/O tool requires that we must set up device drivers and maintain/upgrade these drivers at the regular period to include additional characteristics to the operating device. To support the basic I/O tools, for example keyboard and mouse the operating system contains the device drivers and sets up these drivers at the OS set up time. We don't set them up by hand.

Future Service Expansions of Bogota – TransMilenio System 14 Page No. 3 6 11 2 1. History of BRTS The first BRTS, inaugurated in 1974 in Curitiba, Brazil, caught the world’s attention. The city managers boldly demarcated and dedicated bus lanes on roads perceived as a privileged space for cars. These exclusive lanes improved speed and reduced travel time. Well-designed buses turned intra-city travel a pleasure. Intelligent integration of bus network and city planning reduced trip lengths. BRTS in Bogota (TransMilenio) In 18 December, 2000, the city of Bogotá in Colombia improved upon the Curitiba model and launched its own TransMilenio BRTS. Its resounding success silenced the sceptics and reiterated that wise planning does deliver. Cities were enlightened, and more and more of them reinvented their bus transport system. Ahmedabad BRTS (Janmarg) Indian cities, where the usage of private cars still constitutes a small percentage, had a wellworking bus transport in the past. But over the years, they overlooked modernisation and failed to make sufficient investments. Consequently...

...that we don't become an orphan. We could build up the division and even meet our revenue numbers, yet still not be embraced by the rest of the organization." Indeed, by early June 1995, many group and division managers at the $4.9 billion printing giant had yet to sign on to the strategic potential of digital technology or accept the Digital Division as the most appropriate locale for the business. Some still saw digital printing as a technology in search of a market. Others had indicated that if they did decide to embrace digital printing, they might do so on their own. These concerns were very much on the minds of Schetter and Mary Lee Schneider, the division's director of marketing, as they sat down for a meeting on June 7, 1995. In two weeks Schneider was scheduled to make a presentation to one of Donnelley's business groups, Book Publishing Services, which was deciding whether to move into digital technology on its own or to bring its digital work to the division. Schetter and Schneider were hoping to craft a plan that would convince the Books Group to come to them. But they were still struggling to find convincing arguments and the right set of incentives. Company and Industry Background R. R. Donnelley & Sons was founded in 1864. By 1995, it had become the world’s largest commercial printer, with 41,000 employees in 22 countries. A privately held, family-run, Chicagobased company for almost a century, Donnelley went public in 1956; the first outsider was named chairman...
