Computers

History Of  Computers The  computer  as we know it today had its beginning with a 19th-century English mathematics professor name Charles Babbage. ... Other developments continued until in 1946 the first general-purpose digital  computer , the Electronic Numerical Integrator and  Computer  (ENIAC) was built. First Computers The first substantial computer was the giant ENIAC machine by John W. Mauchly and J. Presper Eckert at the University of Pennsylvania. ENIAC (Electrical Numerical Integrator and Calculator) used a word of 10 decimal digits instead of binary ones like previous automated calculators/computers. ENIAC was also the first machine to use more than 2,000 vacuum tubes, using nearly 18,000 vacuum tubes. Storage of all those vacuum tubes and the machinery required to keep the cool took up over 167 square meters (1800 square feet) of floor space. Nonetheless, it had punched-card input and output and arithmetically had 1 multiplier, 1 divider-...

The Nasa's Supercomputer

The Pleiades aka Nasa's Supercomputer What is the Pleiades? The Pleiades, one of the world's most powerful  supercomputers, represents NASA's state-of-the-art technology for meeting the agency's supercomputing requirements, enabling NASA scientists and engineers to conduct modeling and simulation for NASA projects. This distributed-memory SGI/HPE ICE cluster is connected with InfiniBand in a dual-plane hypercube technology. The system contains the following types of Intel Xeon processors: E5-2680v4 (Broadwell), E5-2680v3 (Haswell), E5-2680v2 (Ivy Bridge), and E5-2670 (Sandy Bridge). The Pleiades is named after the astronomical open star cluster of the same name.

5G- advanced, faster and better.

5G- advanced, faster and better. What is 5G? 5G  is an advanced wireless technology that has begun wide deployment in 2019. 4 million Koreans have 5G phones in October 2019, with 5 million expected year-end. China has deployed over 100,000 base stations. 150 million 5G mobile subscribers are expected in 2020 in China. Nine companies are shipping 5G phones in December 2019, driving prices as low as US$470 in China.   Indoor hubs, sometimes called MiFi, are available from Verizon in the US, Optus in Australia, Three in the UK and others. Virtually every major telco in the developed world is deploying or intends to deploy. 5G millimeter wave is the fastest, with actual speeds often of a gigabit or two. Verizon's 28 GHz network is the largest. Frequencies are above 24 GHz and soon up to 72 GHz. The reach is short, so more cells are required. mmWave 5G bands are 400 MHz, allowing much faster speeds than the lower bands of 20-100 MHz.. mmWave has d...

Hackers Can Shine Lasers at Your Alexa Device and Do Bad, Bad Things to It

Hackers Can Shine Lasers at Your Alexa Device and Do Bad, Bad Things to It Move the Echo away from the window. Now. By  Courtney Linder Nov 6, 2019 A  new paper  funded by DARPA and a Japanese organization for the promotion of science and technology find that simple lasers can basically hack into voice-controlled assistants. Researchers are able to use lasers to inject malicious commands into smart devices, even remotely starting a victim's car if it's connected through a Google account. To be safe, keep your voice devices away from windows in your home. Keep Alexa away from all windows: Turns out hackers can shine lasers at your Google Assistant or Amazon Alexa-enabled devices and gain control of them, sending commands to the smart assistants or obtaining your valuable account information. Researchers proved this by using lasers to inject malicious commands into voice-controlled devices like smart speakers, tablets, and phones ...

Huge DNA Database Just Waiting for Big Ol' Hack

Huge DNA Database Just Waiting for Big Ol' Hack It's the one police used to catch the Golden State Killer. By  Caroline Delbert Nov 6, 2019 THE-LIGHTWRITER GETTY IMAGES Researchers have  breached a crowdsourced DNA database  by reverse engineering a user profile. DNA testing and database sites are vulnerable to many kinds of attacks and data sales. Users must ask themselves if  the potential benefits of DNA testing  outweigh privacy concerns. Genealogy and security are clashing yet again, this time over the massively crowdsourced DNA database GEDmatch.  MIT Technology Review   reports  that computer science researchers designed targeted attacks that breached the GEDmatch database by making complex search strings that let them guess much of users’ DNA. The founder of GEDmatch, Curtis Rogers, told  Tech Review  he’s not that surprised, because genealogy has always involved sharing information and c...
