Operating Systems : 

Design and Implementation – Textbook Only

 [Student Edition]

Description

The Second Edition of this best-selling introductory operating systems text is the only textbook that successfully balances theory and practice. The authors accomplish this important goal by first covering all the fundamental operating systems concepts such as processes, interprocess communication, input/output, virtual memory, file systems, and security. These principles are then illustrated through the use of a small, but real, UNIX-like operating system called MINIX that allows students to test their knowledge in hands-on system design projects. Each book includes a CD-ROM that contains the full MINIX source code and two simulators for running MINIX on various computers.

Android immediately stitches together an expansive panorama photo, ready to share.

A full-featured photo editor lets you add filters and effects, adjust color, straighten, reduce red eye, crop, rotate, flip, and even doodle on your favorite photos–right after you take them. Your edits are saved as a copy, so you can always get to the original.

Your photos can upload themselves with Instant Upload, which makes it much easier to share them with family and friends. If you’ve signed up for Google+, you can enable Instant Upload and share photos with anyone you choose.

Shoot video in Full HD 1080p, and snap still shots while you’re at it. Continuous focus, real-time zoom, and time-lapse mode give you the power to shoot stunning videos. When your footage is ready, create your own movie with Movie Studio and upload it to YouTube. When you shoot videos, you can choose from a number of silly faces and other fun effects. Galaxy Nexus is smart enough to recognize individual facial features–give your friends big eyes, squeeze heads, make noses bigger. Or change the scenery with background replacement.

A 24mm ultra wide-angle lens with a powerful 5x optical zoom gives you the versatility to shoot in any number of situations, and the optical image stabilizer keeps things from getting too shaky when you’re zoomed in tight. Whether you’re out partying or just walking around town, you don’t need to sacrifice style for power–the PowerShot ELPH 300 HS has got you covered for capturing great photos effortlessly.

Canon’s HS SYSTEM improves shooting in low-light situations without the need for a flash, and lowers noise levels at higher ISO settings.

The Canon HS SYSTEM takes the frustration out of low-light shooting, delivering clear, blur-free shots with all the ambiance intact, and freeing you from the sometimes unwanted effects of using the flash. Beautiful low-light shots are possible at both low and high ISO speeds, and the dynamic range is expanded to retain maximum detail in highlight and shadow areas.

The system is the result of two technologies brought together in this compact PowerShot. The first is the 12.1 Megapixel CMOS Sensor, which positions the light-receiving surface for optimal light reception. More light means clearer, blur-free images with plenty of detail and nuance, even in dark areas. Working together with the CMOS sensor to deliver the HS SYSTEM is Canon’s advanced DIGIC 4 Image Processor, which actively reduces noise and delivers high speed image processing.
