serial printer

A printer with a serial interface.

SGRAM

Synchronous Graphic Random Access Memory. A type of DRAM used increasingly on video adapters and graphics accelerators. Like SDRAM, SGRAM can synchronize itself with the CPU bus clock at speeds of up to 100 MHz. In addition, SGRAM uses several other techniques, such as masked writes and block writes, to increase bandwidth for graphics-intensive functions. Unlike VRAM and WRAM, SGRAM is single-ported (it can only be accessed by one device at a time). However, it can open two memory pages at once, which simulates the dual-port nature of other video RAM technologies (access by two different devices simultaneously). See VRAM and WRAM.

SIMM

Single Inline Memory Module. A small circuit board holding a group of memory chips. Typically, SIMMs hold up to nine RAM chips. On PCs, the ninth chip is for parity error checking. Unlike memory chips, SIMMs are measured in bytes rather than bits. In today’s SIMMs, each chip holds 2 MB, so a single SIMM holds 16 MB. SIMMs are easier to install than individual memory chips. The bus from a SIMM to the actual memory chips is 32 bits wide. A newer technology, called dual in-line memory module (DIMM), provides a 64-bit bus. To take advantage of the 64-bit bus on Pentium processors, use either DIMMs or pairs of SIMMs. See DIMMs.

Slot 1

The form factor for Intel Pentium processors. The Slot 1 package replaces the Socket 7 and Socket 8 form factors used by previous Pentium processors. Slot 1 is a 242-pin daughter card slot that accepts a processor packaged as a Single Edge Contact (SEC) cartridge. A system board can have one or two Slot 1s. See SEC.

SMART

Self-Monitoring Analysis and Reporting Technology. A hard drive feature that works in conjunction with system software (for example, LANDesk Client Manager, NEC Auto Backup) for identifying a potential problem on the hard drive and automatically backing up system files to a user-specified device, such as a tape or Zip drive.

sound card

An expansion card designed for sound input and output. Sound cards can record and play back digital audio. Most also have a MIDI synthesizer, which means they can play MIDI files; some also have MIDI inputs and outputs.

super video graphics array (SVGA)

A color bit-mapped graphics display standard that provides a resolution of 1024x 768 with up to 256 colors displayed simultaneously.

synchronous

Refers to protocols that require the clocks of the communicating machines to be coordinated.

VT 300i specifications

The NEC VT 300i is a versatile and compact LCD projector designed for educational environments and business presentations. With its impressive combination of features and user-friendly design, the VT 300i has made a mark as a reliable choice for professionals and educators alike.

One of the standout features of the VT 300i is its brightness. With a robust output of up to 3,000 ANSI lumens, the projector ensures that images are clear and vivid, even in well-lit rooms. This brightness level allows users to deliver impactful presentations without the concern of image washout due to ambient light conditions. Coupled with a high contrast ratio of 400:1, users can expect sharp, detailed images that enhance the overall viewing experience.

The VT 300i showcases advanced DLP projection technology, which is known for producing sharp images with excellent color accuracy. The inclusion of NEC’s proprietary Intelligent Auto Setup feature allows the projector to adjust to various input sources automatically, making setup quick and hassle-free. This ensures that even those who may not be tech-savvy can operate the device with ease.

Another notable characteristic is the VT 300i’s portability. Weighing in at a little over 5 pounds and featuring a compact design, the projector is easy to transport between different locations. This portability is further enhanced by its integrated carrying handle and durable casing, making it suitable for frequent travel.

The connectivity options of the VT 300i also cater to modern technology needs. It includes multiple input terminals, such as HDMI, VGA, and USB, enabling seamless integration with various devices like laptops, tablets, and other media players. Additionally, it supports both wired and wireless presentations, making it versatile for different presentation settings.

User-friendliness extends to the maintenance aspect as well. The VT 300i incorporates an easily accessible filter and lamp compartment, simplifying the process of replacements and ensuring minimal downtime. With a lamp life of up to 5,000 hours in eco mode, it offers longevity and cost-effectiveness.

In conclusion, the NEC VT 300i stands out with its combination of brightness, advanced projection technology, and user-friendly features. Whether in an educational setting or a business meeting, it offers reliability and quality, making it a popular choice for users seeking a competent and portable projector.
