CpG Islands. CpG Islands searches for CpG islands in a DNA sequence using the method described by Gardiner-Garden and Frommer (1987). The calculation is performed using a 200 bp window moving across the sequence at 1 bp intervals. CpG islands are defined as sequence ranges that give a y-value of greater than 0.6 and a GC content of greater than 50%.
A touchscreen is an input and output device normally layered on the top of an electronic visual display of an information processing system. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus and/or one or more fingers. Some touchscreens use ordinary or specially coated gloves to work while others may only work using a special stylus/pen.
There are two different types of peripherals: input devices, which interact with or send data to the computer (mouse, keyboards, etc.), and output devices, which provide output to the user from the computer (monitors, printers, etc.).Some peripherals, such as touchscreens, can be used both as input and output devices.ommon input peripherals include keyboards, computer mice, graphic tablets, touchscreens, barcode readers, image scanners, microphones, webcams, game controllers, light pens, and digital cameras. Common output peripherals include computer displays, printers, projectors, and computer speakers.
