Model : Satellite A135-S4437

Processor : The Intel Core Duo T2250 processor is built with the Mobile Intel 945PM Express chipset, and it has a 1.73 GHz processor speed, fast 533 MHz front-side bus (FSB), and large 2 MB L2 cache. (An L2, or secondary, cache temporarily stores data; and a larger L2 cache can help speed up your system's performance. The FSB carries data between the CPU and RAM, and a faster front-side bus will deliver better overall performance.)

The Intel Core Duo processor has two computational execution cores in a single processor, providing greater system response when running multi-threaded applications simultaneously with no significant increase in power consumption. It's optimized for multitasking and is ready to support the next version of Microsoft Windows, code-named Vista. It can simultaneously run multiple demanding applications--such as graphics-intensive games or serious number-crunching business productivity applications--while downloading music or running virus-scanning security programs in the background. It's more efficient, thanks to Intel's Power Coordination and Deeper Sleep, which help to transfer power only to those areas of the processor that need it. It also features Intel's Digital Media Boost, which delivers enhanced performance on floating point-intensive applications such as CAD tools, 3-D and 2-D modeling, video editing, digital music, digital photography and gaming.

Hard Drive : The 160 GB Serial ATA hard drive (5400 RPM) is about double the average in size for notebook PCs. It provides more than enough capacity for storing documents and productivity software and allows for a good-sized digital media library. This SATA hard drive also quickens the pace with a higher speed transfer of data--akin to FireWire and USB 2.0.

Memory : The 2 GB of built-in memory (PC4200, DDR2 SDRAM) is a very good start for power users, and it offers a decently fast 533 MHz speed.It has two memory slots, enabling you to add up to 4 GB of RAM for worry-free handling graphics-intensive presentations and multiple open business productivity applications. To receive the faster data transfer benefits of the dual-channel DDR2 RAM, any RAM additions require memory modules of same capacity and clockspeed.

DVD/CD Drive : The double-layer DVD drive is compatible with a wide range of formats, including both DVD+RW and DVD-RW discs, CD-RW discs, and dual-layer (DL) DVD+/-R discs, which can hold up to 8.5 GB of data--great for backing up your MP3 collection or your most important documents. It features the following speeds: 4x DVD+R DL, 4x DVD-R DL, 8x for both single-layer DVD+R/-R, 8x DVD+RW, 6x DVD-RW, 5x DVD-RAM, and 24x/16x for CD-R/RW. It reads DVD-ROM discs at 8x and CD-ROMs at 24x.

Keyboard & Mouse : This notebook has a standard 85-key keyboard and electro-static two-button touchpad. It also offers a launch button for the Express CD/DVD media player and control buttons (play, stop, next, previous) as well as a volume control dial.

Screen, Video & Audio
This Toshiba Satellite A105 has a 15.4-inch TFT display with a resolution of 1280 x 800 pixels. It also provides TruBrite technology, which makes images brighter and more vivid thanks to its anti-glare feature. Video is powered by the Intel Graphics Media Accelerator 950, which uses Intel Dynamic Video Memory Technology (DVMT) and provides up to 256 MB of shared video memory. It also features an integrated audio card with headphone and microphone jacks.

Networking, Connectivity & Expansion
This Toshiba Satellite has an integrated tri-mode Intel 3945ABG wireless LAN, which is compatible with 802.11b/g networks (commonly found in home routers and wi-fi hotspots) as well as 802.11a networks (which has a higher throughput, but more limited range--great for closed office environments). You get a good offering of connectivity options:
4 USB 2.0 ports for connecting a wide range of peripherals--from digital cameras to MP3 players
1 FireWire (also known as IEEE 1394 or i.Link) port for connecting digital video camcorders and other peripherals
1 VGA monitor port
1 S-Video out
1 PCMCIA (or PC Card) slot (Type II, PCMCIA R2.01, PC Card16, CardBus)
1 headphone jack, 1 microphone jack
5-in-1 memory card reader that's compatible with Secure Digital (including SDIO), MMC, Memory Stick, Memory Stick PRO, xD Picture Card memory cards

It also has an integrated 56K modem (V.92) and an RJ-45 LAN network port (for a 10/100 Fast Ethernet connection to networks and DSL/cable modems).

Operating System
Windows Vista Home Premium is the operating system for users with advanced computer needs, and it includes all of the Windows Media Center capabilities for turning your PC into an all-in-one home entertainment center for watching DVD movies and accessing your digital audio library.You can also use Windows Media Center to record and watch your favorite TV shows (even HDTV) and to access new kinds of online entertainment content. Computers that include Windows Vista Home Premium and an auxiliary Windows SideShow display will also allow you to access key data even when your computer is off. It is also easier than ever to share files between other PCs in your household and to manage your laptop computer settings to more securely connect to your favorite WiFi hotspot.

Every edition of Windows Vista provides the essential tools and technologies to help protect you whether you are browsing the Internet, connecting to a wireless network, or just reading e-mail. All editions of Windows Vista include new tools that can warn you of impending hardware failures long before you have lost any important personal data. And, all Windows Vista editions include parental control features that allow you to manage and monitor your family's use of games, the Internet, instant messaging, and other activities.
