QUES: Simple stepper motor drivers entirely energize or entirely de-energize the field windings, leading the rotor to "cog" to a limited number of positions; more sophisticated drivers can proportionally control the power to the field windings, allowing the rotors to position between the cog points and thereby rotate extremely smoothly. This mode of operation is often called microstepping. Computer controlled stepper motors are one of the most versatile forms of positioning systems, particularly when part of a digital servo-controlled system.
What is another name for smooth rotation?

ANS: microstepping

QUES: IBM announced it will launch its new software, called "Open Client Offering" which is to run on Linux, Microsoft Windows and Apple's Mac OS X. The company states that its new product allows businesses to offer employees a choice of using the same software on Windows and its alternatives. This means that "Open Client Offering" is to cut costs of managing whether to use Linux or Apple relative to Windows. There will be no necessity for companies to pay Microsoft for its licenses for operating systems since the operating systems will no longer rely on software which is Windows-based. One alternative to Microsoft's office document formats is the Open Document Format software, whose development IBM supports. It is going to be used for several tasks like: word processing, presentations, along with collaboration with Lotus Notes, instant messaging and blog tools as well as an Internet Explorer competitor – the Mozilla Firefox web browser. IBM plans to install Open Client on 5% of its desktop PCs. The Linux offering has been made available as the IBM Client for Smart Work product on the Ubuntu and Red Hat Enterprise Linux platforms.
What do you need to pay Microsoft if you use Open Client Offering software?

ANS: unanswerable
