Video random-access memory (VRAM) is dedicated computer memory used to store the pixels and other graphics data as a framebuffer to be rendered on a computer monitor. [1] It often uses a different technology than other computer memory, in order to be read quickly for display on a screen.
Video memory was shared with the first 128 KiB of RAM. The exact size of the video memory could be reconfigured by software to meet the needs of the current program. An early hybrid system was the Commodore Amiga which could run as a shared memory system, but would load executable code preferentially into non-shared "fast RAM" if it was available.
IdeaPad (stylized as IDEAPΛD and formerly ideapad) is a line of consumer-oriented laptop computers designed, developed and marketed by Lenovo. The IdeaPad mainly competes against computers such as Acer 's Aspire , Dell 's Inspiron and XPS , HP 's Pavilion , Envy , Stream , and Spectre , Samsung 's Sens and Toshiba 's Satellite .
The IdeaPad S10 was Lenovo's first netbook. [4] While Engadget found the design unremarkable, the low starting price was well-received. [4] The S10 featured a 10.2-inch (260 mm) TFT active matrix 1024×576 or 1024×600 display with an 80 or 160 GB hard disk drive and 512 MB or 1 GB DDR2 Random Access Memory, both of which could be upgraded via a trap door on the bottom of the netbook.
The last of the IdeaCentre B Series desktops released in 2010, the B310 could be equipped with Intel Core i3 or i5 processors, up to 4 GB RAM, and up to 1 TB hard disk drive. [11] The desktop offered ATI Radeon HD 5450 discrete graphics, a 21.5-inch HD screen with an aspect ratio of 16:9 and integrated stereo speakers. [ 11 ]
The U300s includes a 13-inch display, an Intel U series Core i7 or i5 processor, an SSD with options for 128 or 256 GB of storage. [3] The U300s makes use of Intel's HD Graphics 3000 integrated with the CPU, includes an HDMI port, and supports Intel's WiDi standard for wireless graphics.
Many 32-bit computers have 32 physical address bits and are thus limited to 4 GiB (2 32 words) of memory. [3] [4] x86 processors prior to the Pentium Pro have 32 or fewer physical address bits; however, most x86 processors since the Pentium Pro, which was first sold in 1995, have the Physical Address Extension (PAE) mechanism, [5]: 445 which allows addressing up to 64 GiB (2 36 words) of memory.
Best Buy released an alternative version of the Yoga 13 with an Intel Core i5 processor (vs. Lenovo's base model's i3 processor) and no Microsoft Office (whereas Lenovo's base model includes Microsoft Office). Its smaller cousin, Yoga 11, which runs Windows RT (as opposed to the Yoga 13, running Windows 8), was released in December 2012. [1] [2]
