TTL signal

A TTL (Transistor-transistor-logic) signal is a digital signal level for controlling the screen colors. With TTL driving, the red, green and blue signals can only be switched on or off or provided with an intensity signal. A TTL-driven monitor can thus display a maximum of 64 colors. Video standards such as MDA, CGA and EGA are based on TTL level.

U

USB or Universal Serial Bus

A smart plug for PC peripherals. USB automatically determines resources (like driver software and bus bandwidth) required by peripherals. USB makes necessary resources available without user intervention.

●USB eliminates "case angst" -- the fear of removing the computer case to install add-on peripherals. And USB also eliminates adjustment of complicated IRQ settings when installing new peripherals.

●USB does away with "port gridlock." Without USB, PCs are normally limited to one printer, two Com port devices (usually a mouse and modem), one Enhanced Parallel Port add-on (scanner or video camera, for example) and a joystick. More and more peripherals for multimedia computers arrive on the market every day. With USB, up to 127 devices can run simultaneously on a computer.

●USB permits "hot plug-in." There's no need to shut down, plug in, reboot and run set-up to install peripherals. And no need to go through the reverse process to unplug a device.

In short, USB transforms today's "Plug-and-Pray" into true Plug-and-Play!

Hub

A Universal Serial Bus device that provides additional connections to the Universal Serial Bus.

Hubs are a key element in the plug-and-play architecture of USB. The Figure shows a typical hub. Hubs serve to simplify USB connectivity from the user's perspective and provide robustness at low cost and complexity.

Hubs are wiring concentrators and enable the multiple attachment characteristics of USB. Attachment points are referred to as ports. Each hub converts a single attachment point into multiple attachment points. The architecture supports concatenation of multiple hubs.

The upstream port of a hub connects the hub towards the host. Each of the other downstream ports of a hub allows connection to another hub or function. Hubs can detect, attach and detach at each downstream port and enable the distribution of power to downstream devices. Each downstream port can be individually enabled and configured at either full or low speed. The hub isolates low speed ports from full speed

107P specifications

The Philips 107P is a classic monitor that has made a significant mark in the world of computer displays, particularly during its time of release. This 17-inch CRT monitor is known for its reliability, vivid color reproduction, and solid performance for both general computing and gaming needs.

One of the standout features of the Philips 107P is its image quality. The monitor employs a diamond flat screen technology that minimizes glare and reflection, allowing for clearer images even in brightly lit environments. The screen boasts a maximum resolution of 1280x1024 pixels, ensuring sharp visuals for various applications, from graphic design to gaming. The monitor also supports a refresh rate of up to 85Hz, which reduces flicker and provides a smoother viewing experience, particularly beneficial during prolonged use.

The 107P integrates several technologies that enhance the viewing experience. The Philips 107P features advanced color processing technology that contributes to accurate and vibrant colors, making it suitable for tasks requiring precise color representations, such as photo editing. Additionally, the monitor includes an automatic degauss feature, which helps to eliminate any magnetic interference that may distort the displayed image.

Ergonomics is another notable aspect of the Philips 107P design. The monitor is equipped with a height-adjustable stand, allowing users to customize their viewing height for maximum comfort. It also features tilt functionality, enabling users to adjust the angle of the screen to reduce neck strain during extensive use.

Connectivity options are practical for its time, with standard VGA input, making it easy to connect to most computers. The monitor is designed to be energy efficient, aligning with Philips' commitment to sustainability. This not only helps in reducing electricity consumption but also extends the longevity of the monitor.

In conclusion, the Philips 107P remains a noteworthy choice for users who value quality and reliability in their monitor choice. With its impressive image quality, ergonomic design, and exceptional color fidelity, it has earned its place in the legacy of computer displays. Whether for casual use or professional applications, the Philips 107P is a testament to the enduring quality of CRT monitors in the digital age.
