Questions and Answers

More Info

Microsoft Windows® 7 Professional
With enhanced productivity features to streamline routine tasks, it also simplifies network connections and has several security protections including automatic system and network backups. Entertainment has never  been cooler than with Windows Media Center. You can watch, pause, and record live programs, enjoy a variety of online entertainment, or take a break with your best music. Windows 7 also supports DirectX 11. Gamers will love its smoother 3D animation and realistic graphics.

Microsoft® Windows 8
This is a whole new user experience for Windows fans. Right from the Start screen, Windows 8 invites users to build a personalized environment for every need, discover apps for fun and essential tasks, and engage in the adventure of technology. Animated tiles provide timely updates on weather, social media, news and all things important to you. View and share photos from a single app, centralize all of your email accounts in one place, streamline managing messaging and social media contacts.

Works with touchscreen-enabled systems to allow tap, zoom, and swipe capabilities and it still works with the traditional keyboard and mouse so moving between windows and programs is as easy as a swipe or a click. Other cool new features include picture password, snap windows for easy multitasking, apps to simplify cloud access and storage for documents, your favorite music, and more.

1TB Hard Drive
A terabyte equals one trillion bytes. To put that in perspective, that's room enough for about 250,000 MP3 files, or according to Ron White, in his book, "How Computers Work", 20,000 four-drawer filing cabinets filled with text. In addition, this hard drive operates at a variable RPM which means you've got the best of both worlds, full speed for demanding loads and energy conservation during minimal access.

Smart Cache
With Intel Smart Cache you benefit from increased data access because the cache is shared between the cores from a single access point and optimized by workload demand. That means your system is making maximum use of its resources, enhancing multi-threading, and reducing storage redundancy.

Intel® HD Graphics
Picture this, stunning visuals rendered with incredible realism for the ultimate computing experience. That is the beauty of Intel HD Graphics. Behind the scenes, an advanced video engine supporting multi-functional data processing, dynamic load balancing, multi-threading, and the ability to switch between integrated and discrete graphics, processes graphic and media data so you see high-quality content whether you're working, watching high-definition video, or proving your mastery of the latest 3D games.

RealTek ALC662 Audio
Windows Vista desktop and mobile PC users will find this 5.1 channel HD audio solution is the perfect match for multimedia PCs. It offers many software utilities such as Karaoke mode with voice cancellation and key shifting, optional Dolby®, Digital Live, DTS® CONNECT™, and Dolby Home Theater programs, making it well-suited for home entertainment and gaming.

Intel Virtualization Technology
Consolidates multiple environments into a single server or PC. It provides greater user flexibility that can help reduce costs, improve security, and increase resiliency regarding contingency planning.

Intel 64
Take advantage of 64-bit computing when using 64-bit compatible software. This architecture enables systems to access more than 4GB of virtual and physical memory. Also known as EM64T, it is fully compatible with 32-bit operating systems giving you the flexibility to upgrade to a 64-bit OS when ever you're ready. Intel's 64 architecture works on servers, workstations, desktops, and mobile platforms.

Enhanced Intel SpeedStep® Technology
Now get even more performance enhancing, energy conserving benefits from Intel. With SpeedStep technology, your processor simultaneously switches voltage and frequency to high or low levels depending on processor load. Enhanced SpeedStep technology performs voltage and frequency changes separately so the system performs better with reduced latency due to system unavailability.

Thermal Monitoring Technologies
This feature is designed to protect the processor in the event of unusual circumstances such as cooling fan failure which can cause damage if internal chassis temperatures become higher than normal. It works by reducing the processor's power consumption if the programmed thermal temperature is exceeded.

The processor contains a thermal diode which measures the actual CPU temperature and relays its temperature and thermal requirements to the motherboard. The motherboard uses those requirements to control the processor fan and ensure it does not spin faster than necessary - even under worst case power use.

Execute Disable Bit
Reduces your system's exposure to viruses and mal-ware attacks, and the chances of self-executing and propagating software from taking down your system or network. That can save you costly repairs, lost productivity, and revenue.

Extended Page Tables
Boosting memory for demanding virtualizaiton applications, this hardware optimization, also known as Second Level Address Translation (SLAT), helps reduce power consumption and its associated costs while also aiding battery life.

10/100/1000 Gigabit Network
Just when you thought life couldn't go any faster, technology changed the rules.

Multi-in-1 Digital Media Card Reader
Got your life preserved in pictures and video? You'll love the high-performance media card reader in the PowerSpec B331. Not only does it handle a variety of formats, this high-performance tool makes managing your data a snap. And, with the click of a single button, you can run your best slide shows on your monitor. Using more bandwidth and full-duplex capacity, the 10/100/1000 Gigabit Ethernet will have you connecting with the Internet or your other devices faster than you can say gigabit.

Windows Live™ Essentials
Now have even more fun with Windows Live Essentials. With programs like Movie Maker you can be the creative director of your own media studio turning your videos and photos into memorable works of art complete with sound and special effects. Then share your artistic works with family and friends while you're chatting via Messenger. There's also programs for managing multiple e-mail accounts, parental controls, and even a program for creating a cool blog.
