LCoS (Light Crystal over Silicon) is a technology used in display systems. LCoS shares some elements with LCD and DLP (Digital Light Processing) displays. As such, LCOS systems are not exactly new though it was only recently that commercial manufacture became viable. The best way to understand LCoS television is to understand the process. How …
Secure Digital (SD) memory cards are very simple to format. There are 3 main options to format the SD cards to the format needed. To successfully format an SD card, the write protection lock on the side of the card must be in the “unlock” position. SD mini and micro SD cards must be used …
A hard disk partition is a defined storage space on a hard drive. Most operating systems allow users to divide a hard disk into multiple partitions, in effect making one physical hard disk into several smaller logical hard disks. Reasons to Use Hard Disk Partitions A user may decide to split a hard disk into …
