Put simply, a 3D printer is a device which prints real three-dimensional objects rather than flat images onto two-dimensional sheets of paper. The designs for the 3D objects are stored in modelling software on a computer and can be created from scratch or input via a 3D scanner. Various technologies exist, but all currently construct models by building them from layers of material, one on top of the other, which are fused together during the process. Working machines and even electrical circuits can be printed in this way.
This is a monitor that’s capable of displaying ultra-high definition content at a resolution of roughly 4000 pixels horizontally. Although actual resolutions may vary, the most common is 3840×2160 pixels, which is the equivalent resolution of four ‘Full HD’ screens arranged in a 2×2 rectangle.
IEEE 802.11 is a set of media access control (MAC) and physical layer (PHY) specifications for implementing wireless local area network (WLAN) computer communication in the 900 MHz and 2.4, 3.6, 5, and 60 GHz frequency bands. They are created and maintained by the Institute of Electrical and Electronics Engineers (IEEE) LAN/MAN Standards Committee (IEEE 802). The base version of the standard was released in 1997, and has had subsequent amendments. The standard and amendments provide the basis for wireless network products using the Wi-Fi brand. While each amendment is officially revoked when it is incorporated in the latest version of the standard, the corporate world tends to market to the revisions because they concisely denote capabilities of their products. As a result, in the market place, each revision tends to become its own standard.
