If the overhead projector is not working, try to push the button more slowly, and you can feel the “click”. Inside the overhead projector, usually it is like a television, but Read More

ATM (Asynchronous Transfer Mode) is a technological system developed for both local and wide area networks (LAN and WAN), and designed to handle data as well as video and voice traffic in real time, all at the same time. The system architecture makes use of switches that set up logical circuits at both ends of the data stream, which ensures unprecedented quality of service (QoS). Unlike conventional telephone switches that sets up dedicated end-to-end circuits, unused bandwidth in Asynchronous Transfer Mode (ATM) can be used for other purposes if needed. Read More

The term CDFS (CD File System) is used for both the Linux and Windows Operating Systems (OSs). CDFS is a file system that was created for Linux in 1999 and exports all boot images and tracks on a CD as normal files.

CDFS also uses a VCACHE driver to control CD-ROM caches on Windows computers, which makes music playback smoother. CDFS Commands on Linux CDFS Read More

A SODIMM (Small Outline Dual Inline Memory Module) is a series of small DIMM chips that is specifically designed to fit into smaller working environments such as mobile devices and notebook computers.

The Fine Structure Constant is a constant in theoretical physics that determines the strength of the interaction between two opposing electromagnetic waves. The Fine Structure Constant is used for a wide variety of purposes, but is entirely hypothetical and does not depend on any real units of physics. For example, the Fine Structure Constant can be used to determine the displacement of a beam of light as it comes in contact with a radio wave or vice versa. How the Fine Structure Constant Works The Fine Structure Constant is defined Read More
