Google will release 3rd Android 11 developer preview in May 2020. According to Google , the first beta version of Android 11 is due to be released in May 2020, and platform stability should be achieved in June. Google has released a new developer preview of Android 11. The third pre-release now brings some new features that could make it easier for programmers. The Exit Reasons API, for example, can be used to get details after an app suddenly quits. In the third preview version, Google updated the API based on user suggestions. The new ADB incremental mode should speed up the transfer of files via ADB (Android Debug Bridge). The installation of very large APK files via ADB can sometimes take a long time and thus reduce productivity.  Thanks to ADB Incremental, the transfer of files with more than 2 GB should be up to ten times faster. In the pre-release version, the new mode only works with the Pixel 4 and Pixel 4 XL, but after the start of Android 11, all new devices sho

Two 400 connections can be combined in the future for a transmission of 800 gigabits per second

on

The latest tech news is Ethernet Technology Consortium has published the 800GBASE-R specification, which can be used to transmit 800 gigabits per second on an Ethernet basis. 



The group of companies describes in 800GBASE-R how to couple two 400 Gigabit/s connections that work according to IEEE 802.3bs. Internally, 800GBASE-R bundles eight lanes of 106 GBit/s each.

Officially published technology news articles about that A new media access control layer (MAC) and a new physical medium attachment (PMA) take over the signal bundling. Since the 800GBASE-R standard continues to use the previous physical coding sublayers (PCS), the forward error correction (FEC) used so far also continues to work.

IT news For data centers

Network standards with several hundred GBit/s are primarily intended for data centers in which the operators network hundreds to thousands of nodes. So far, proprietary interconnects have often been used, for example Crays Slingshot.

The Ethernet Technology Consortium includes the network suppliers Arista, Broadcom and the Nvidia subsidiary Mellanox as well as the server operators Cisco, Dell, Google and Microsoft. Until March 2020, the Ethernet Technology Consortium was still called "25 Gigabit Ethernet Consortium". Since 25 Gbit/s is no longer up to date in data centers and the consortium will be preserved in the future, the network has given itself a more flexible name.

1-Gigabit Ethernet is the most common for desktop PCs, notebooks and routers. Only upper-class mainboards are increasingly using 5 or 10 GBit/s. In the middle class, the change to 2.5 GBit/s begins gradually.
