Three interesting examples of IT solutions from different decades

Week-1

Touch ID



It is an electronic fingerprint recognition feature which is created and published by Apple Inc in the late 2013's. It enables users to unlock devices, make purchases and authenticate Apple pay, etc. It first came out after the first release of Iphone 5S. In 2015, Apple introduced a faster second-generation version with a new Iphone 6s. Then in 2016, Apple integrated the Touch Id to the Macbook Pro on the right side of its touch bar. It is also used on Ipads since the Ipad Air 2 which was the first ever Ipad that had Touch Id. Users can create more than one fingerprints and use them at a time. Fingerprint information is stored locally in a secure enclave on the Apple A7 and later chips, not in the cloud, a design choice intended to make it impossible for users or malicious attackers to externally access the fingerprint information.



Google





It began in January 1996 as a research project by Larry Page and Sergey Brin when they were both PhD students at Stanford. And was first introduced in the late 1998. This algorithm they developed was unique, since it ranked pages not only based on their content, but on how many other webpages linked back to them. They discovered that links to a page were a sign of its online authority, and as a result, Google's algorithm returned more useful results, propelling Google to the top of the search engine rankings. Despite the fact that Google has now expanded its offerings outside search, the search engine remains the company's most popular service.



Bluetooth


Other IT solution which I want to mention is bluetooth technology. It is a high-speed low powered wireless technology link that is initially designed to connect phones or other portable equipment together. It is an (IEEE 802.15.1) specification for the use of low-power radio communications to connect phones, computers, and other network devices over short distances without the use of wires. Physical range is typically up to 10 m. In general, Bluetooth-connected devices are extremely safe against hackers. Because they work with various frequencies and the devices bounce between them 100s of times per second, this is referred to as the "frequency-hopping spread spectrum.".



In May 1998, the Bluetooth SIG was launched with IBM and Ericsson as the founding signatories and a total of five members: Ericsson, Intel, Nokia, Toshiba and IBM. The first consumer Bluetooth device was launched in 1999. 

To conclude, IT solutions in general make our lives easier and somewhat more convenient in terms of digital environments.

 Accessibility to the technology Week-14 Gaming Players with physical limitations are something that some developers have a hard time accommodating. To excel in many games, you'll need quick reflexes and rapid, precise inputs. And, especially in multiplayer settings, difficulty and other gaming features cannot be adjusted just for one person, as this could be exploited. Input controllers must be modified to do this.  Everyone can like gaming. Some games can be less approachable than others, but the medium as a whole must be accessible. When cost-effective, it's critical for developers to take steps to cater for a wide range of abilities. When that isn't possible, input elements that are specifically intended can aid.

 Book Review Future Crimes by Marc Goodman           This is the book which I really enjoyed reading and get to know many aspects of IT which I have not really aware of.  To start with, the book introduces us the dark side of the digital world. How to sabotage the world's best-protected nuclear facility?  Why are the top secret records of million dollar companies on paper?  With which software are the world-wide trading exchanges manipulated?  What is hidden in the depths of the Internet?  Why are the internet services you use every day free?  Why does the game you just downloaded on your phone want to access your guide?  How are virtual money and online games used for money laundering?  Is the future the age of hackers and malware?  The answers to all these questions are included in the book. The book focuses on new types of crime in our age.  Cyber ​​attacks, computer viruses, hackers and malware.  It...
