Toslink Toslink is a type of digital audio connection developed by Toshiba Corporation. It uses a fiber optic cable to transmit an audio signal in the form of pulses of light. A single Toslink cable can be used to carry a mono, stereo, or even a surround audio signal. Toslink is similar to the Sony/Philips …
Touchpad A touchpad or “trackpad” is a flat control surface used to move the cursor and perform other functions on a computer. Touchpads are commonly found on laptops and replace the functionality of a mouse. A touchpad is designed to be controlled with your finger. By sliding your fingertip along the surface, you can move …
Touchscreen A touchscreen is a display that also serves as an input device. Some touchscreens require a proprietary pen for input, though most modern touchscreens detect human touch. Since touchscreen devices accept input directly through the screen, they do not require external input devices, such as mice and keyboards. This makes touchscreens ideal for computer …
Trackball A trackball is an input device used to enter motion data into computers or other electronic devices. It serves the same purpose as a mouse, but is designed with a moveable ball on the top, which can be rolled in any direction. Instead of moving the whole device, you simply roll the moveable ball …
Transistor A transistor is a basic electrical component that alters the flow of electrical current. Transistors are the building blocks of integrated circuits, such as computer processors, or CPUs. Modern CPUs contain millions of individual transistors that are microscopic in size. Most transistors include three connection points, or terminals, which can connect to other transistors …
Trinitron Trinitron was a pioneering CRT (Cathode Ray Tube) technology developed by Sony Corporation. Unlike conventional CRTs that use a shadow mask, Trinitron utilized an aperture grille. A shadow mask is a metal plate with tiny holes that guide electron beams to specific phosphors on the screen, creating an image. In contrast, an aperture grille …
TRS Stands for “Tip-Ring-Sleeve.” TRS is an analog audio plug with three connection points (tip, ring, and sleeve). It comes in two standard sizes: 1/4-inch and 1/8-inch. An 1/8-inch (or 3.5 mm) TRS jack is often called a “headphone jack” since it is the standard audio connector used by headphones. A TRS plug has two …
Ultra DMA Stands for “Ultra Direct Memory Access.” Ultra DMA, also abbreviated UDMA, is an interface that transfers data between a computer and a storage device (usually a hard drive). It is the fastest version of DMA, replacing Word DMA (or WDMA) and supporting a burst transfer speed of up to 133 MB/s. Like all …
Ultrabook Ultrabook⢠is an Intel trademark that describes a laptop specification. Notably, ultrabooks have an Intel CPU, SSD storage, and a thin unibody frame. Ultrabooks are so thin that they do not have an optical drive, such as a DVD player. The initial Ultrabook spec was announced in 2011, which included an Intel “Sandy Bridge” …
Unified Memory Architecture Unified Memory Architecture (abbreviated UMA) is a type of computer memory architecture that uses the same pool of memory for both the CPU and GPU. It is commonly used in computers with integrated graphics processors, as well as mobile devices like smartphones and tablets. Computers with discrete graphics processing units have separate …
