Apple has made a settlement with Japanese regulator that it will allow developers of “reader” apps link to their own website for managing users account. The change goes to effect in early 2022. This settlement comes after the Japan Fair Trade Commission (JFTC) has forced Apple to make a change its polices on the reader apps, like Netflix, Spotify, Audible and Dropbox, that provide purchased content or content subscriptions for digital magazines, newspapers, books, audio, music, and video. Image © Techcrunch “We have great respect for the Japan Fair Trade Commission and appreciate the work we’ve done together, which will help developers of reader apps make it easier for users to set up an manage their apps and service, while protecting their privacy and maintaining their trust,” Phill Schiller, who oversees the App Stores at Apple. While the update was made as part of an agreement for the JFTC to end its probe, which only applies to the Japanese market, Apple said it would apply this ch

In today's world data or I should say information is very valuable. If it is not manage properly, it can create problems. So, to manage data properly company hire professional to do the job. This is also growing IT fields. It is also useful in work if Journalists, because they have to represent data properly. If people know how to manage or design data it can be di helpful. So, the person who is interested in data management. This post will be very useful for them. I am going to tell about 5 awesome book for data management to start. "Database Management Systems" by Raghu Ramkrishna. Database Management Systems (DBMS), based on the introductory database course at the University of Wisconsin-Madison and class-tested at over 20 universities, is a must for any course in database or file organizations. DBMS provides a hands-on approach to relational database systems, with an emphasis on practical topics such as indexing methods, SQL, and database design. This book also provid

Spanning Tree Protocol (STP) is a Layer 2 protocol that runs on bridges and switches. The specification for STP is IEEE 802.1D. The main purpose of STP is to ensure that you do not create loops when you have redundant paths in your network. Loops are deadly to a network. When too many computers try to send at the same time, overall network performance is affected and can bring all traffic to a near halt. That's why STP is used to solve this issue.  A bridge looks at the destination address and, based on its understanding of which computers are on which segments, forwards the data on the right path via the correct outgoing port. Network segmentation and bridging can reduce the amount of competition for a network path by half  assuming each segment has the same number of computers. As a result, the network is much less likely to come to a halt. When STP is enabled, each bridge learns which computers are on which segment by sending a first-time message to network segments. Through thi

Superconductors are important materials that can conduct electricity without resistance when cooled below a certain temperature, making them highly desirable where energy consumption needs to be reduced. It show quantum properties which are very usefull for building computers that use quantum physics to store data and perform computing operations, and are specific. Much better than the best supercomputers on the task. As a result, leading high-tech companies such as Google, IBM, and Microsoft are in increasing demand for industrial-scale quantum computers using superconductors. However, the elementary units of quantum computers (qubits) are extremely sensitive and lose their quantum properties due to electromagnetic fields, heat and collisions with air molecules. Protection from these can be achieved by making more resilient qubits using a special class of superconductors called topological superconductors which in addition to being superconductors also host protected metallic states o

Windows 11 UI Windows 11 is an upcoming Windows NT Operating System. It is written in C, C++, C# and Assembly language. The leaked development build of Windows 11 features an updated user interface that follows Microsoft's Fluent Design guidelines; translucency, shadows, and rounded corners are prevalent throughout the system. A redesigned Start menu is used, which eliminates the tiles on the right side. The taskbar is also streamlined and centered by default, similar to the macOS Dock, however left-align option remains. Task View, a feature introduced in Windows 10, features a refreshed design. Other changes to the system include new system icons, animations, sounds, and widgets. With Windows 11, when users click the maximise button, they will see options about how they want to lock the window in place. There will be options like side by side with another app, or a grid-based view of three or four windows. here's a first look at Windows 11. There's a new Start menu, round

Docker is an open source containerization platform. Docker enables developers to package applications into containers—standardized executable components that combine application source code with all the operating system (OS) libraries and dependencies required to run the code in any environment. While developers can create containers without Docker, Docker makes it easier, simpler, and safer to build, deploy, and manage containers. It’s essentially a toolkit that enables developers to build, deploy, run, update, and stop containers using simple commands and work-saving automation. What is container?  A container is a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another. A Docker container image is a lightweight, standalone, executable package of software that includes everything needed to run an application: code, runtime, system tools, system libraries and settings. Container ima

What is RPA?   RPA (Robotic Process Automation) is technology which let organization to make their task easy by allowing them to automate the task just like a human being was doing them across  application and systems. The purpose of RPA is to transfer the process execution from humans to bots. Robotic process automation interacts with the existing IT architecture with no complex system integration required. UiPath - The vendor UiPath is a New York City-based global software company that develops a platform for robotic process automation (RPA). The company's software monitors user activity to automate repetitive front and back office tasks, including those performed using other business software such as customer relationship management or enterprise resource planning (ERP) software.   UiPath develops software to automate repetitive digital tasks normally performed by people. The technology combines emulating how humans read computer screens (AI Computer Vision) with APIs, and give

Python Python is a amazing programming language and easy to learn. It is a high level programming language and also good for beginners. It's framework tools like Django and Pyramid are amazing and very useful. Python used in various fields like Ethical Hacking, Machine Learning and Artificial Intelligence, Data Science, etc. Java Its Write Once Run Anywhere feature allows the code to be originally prepared on one machine and run on another. Its popularity can be understood by the fact that Java was Google’s choice for developing applications for Android at the time of its launch. Java comes with automatic memory allocation and garbage collection, features that ensure sufficient CPU memory for use by other application.  GO Go language was developed at Google to overcome the failings of other coding languages used by developers. In doing so, they wanted to resolve their collective dislike for C++ programming techniques. Programming languages trends of 2021 suggest a rising interest f

DHCP is a client server protocol and it stands for dynamic host configuration protocol. It is used for network management protocol to dynamically assign an Internet Protocol address to any device on the network. So they can communicate using IP.  The primary reason DHCP is needed is to simplify the management of IP addresses on networks. No two hosts can have the same IP address, and configuring them manually will likely lead to errors. Even on small networks manually assigning IP addresses can be confusing, particularly with mobile devices that require IP addresses on a non-permanent basis. Also, most users aren’t technically proficient enough to locate the IP address information on a computer and assign it. Automating this process makes life easier for users and the network administrator.

  Image © Stack Overflow Init is a process in Unix-based operating system. It start at booting of the system. Kernel begin this process with proper requirements . It is considered as daemon process and it continues running until the system is closed. Init play important part in system. If the kernel fail to start init in proper way, the kernel panic will occur. Init is configured in /etc/inittab file where the runlevels are defined. Depending on the services in /etc/inittab, several scripts are run by init. The entire process of start and shut down the system is based on init. I nit is parent of all Linux processes with PID or process ID of 1. It is the first process to start when a computer boots up and runs until the system shuts down. In simple words the role of init is to create processes from script stored in the file /etc/inittab which is a configuration file which is to be used by initialization system. It is the last step of the kernel boot sequence.

To understand nanites you have to know what is nanotechnology. So, Nanotechnology is a field of research and innovation concerned with buildings things - generally, materials and device in the scale of atoms and molecules. The ideas of nanoscience begins with the book "There's Plenty of Room at the Bottom" by Richard Feynman. The nanites are famous because sci-fi series like 'Revolution" NBC's series and Vin Diesel movie 'Bloodshot'. Nanotechnology are developed at that level yet. Nanites is name for Nanorobotics it also has other like nanoids. It is technology field creating machine or robots whose component are at or near nanometers ( 10^-9 meters ). Example of nanorobotics are sensor having a switch approximately of 1.5 nanometer, able to count approximately molecules in chemical sample and a amazing single molecule car, wheel made of Buckminsterfullerene also called as Nano Car.  Potential use of nanotechnology is in nanomedicines.

image© Wikipedia Schottky diode is a semiconductor diode which has low forward voltage drop and a very fast switching speed. The junction between an aluminum and n-type semiconductor constitutes a diode, known as Schottky diodes. The aluminum n-type Schottky diode has a cut in voltage of about 0.35 V. It is also known as Schottky barrier diode and hot-barrier diode.  When a Schottky diode is forward biased, that is positive terminal of a battery is connected to the metal and the negative terminal to semiconductor, current across the junction due to flow of electrons from semiconductor to the metal. Electrons thus entering the metal cannot be distinguished from the plentiful electrons already present in the metal and hence these do not constitute minority carriers. Therefore, when the junction voltage is reversed the problem of removal of the excess minority charge does not exist. Hence Schottky diode exhibit negligible storage time.   Construction and Symbol

LiFi stands for light fidelity. It is a wireless optical networking technology and it uses light emitting diode for data transmission. Its close similar to Wi-Fi, but it uses light instead of radio waves. Which make it so special. LiFi can be up to 100 time faster than WiFi. It uses light to transmit data, which give it advantages of working in areas which is susceptible to electromagnetic interference. The light wave cannot penetrate the walls which translates to much shortage range, and lower hacking potential compare to WiFi.  HOW LI -FI WORKS ? image © pureLiFi LiFi works on a Visible Light Communication system. VLCs works by switching the current to LEDs off at very high speed. The technology made LED light bulb emit pulses which is undetectable to human eye and with those limited pulse, data can travel to and from receivers. The receiver than collect data and then interpret them. LiFi can  touch the transmission speed at 100Gbps 14 times faster than WiGig, the fastest WiFi in wor

Operating system is software that runs in kernel mode even that is not always true. Part of the problem is that operating system perform two essential unrelated function. We can say that operating system is system software that manages computer hardware, software resources, and provide common services for computer program.  The Operating System as an Extended machine The architecture of most computers at the machine language level is not developed and difficult to program, especially for input/output. To make this point more concrete, consider modern SATA hard disks used on most computers. Only the insane the programmer would try to mess with hard disks at the hardware level. Therefore disk driver - a piece of software deals with hardware and provide interface to read and write disks blocks. Operating System  contain many drivers for control input/output device. Macintosh hardware are complicated. Real processors, memories, disks, and other devices are very complicated and its interfa

So welcome to my blog. In this post I am gonna write about SCADA network. This actually come to my mind because of web show named Mr. Robot. The show is awesome if you love hacking believe me you will enjoy the series. So basically the SCADA ( Supervisory Control and Data Acquisition ) is a control system architecture comprising computers, networked data communications and graphical user interface for high level process supervisory management, while also comprising other peripheral devices like programmable logic controllers and discrete proportional-integral-derivative controllers to interface with process plant or machinery. SCADA networks used for monitoring and controlling the  industry like  telecommunication, water plant, etc. It is one of the most commonly used industrial control system, in spite of concerns about SCADA system being vulnerable to cyberattack.  This network is used for gathering info about the system, transferring that info to central site, alerting the home stat

Data Center Interior In todays life, computers are becoming so basic needs for human. Even every house has a computer actually not house only every person has PC or laptop of their own. So it is necessary to know about computers and network. As we all use internet which use network to work. Servers is also a part of it, a very important part. A basically a server is a piece of computer which provides data to other computers. There is many types of server like web servers, mail servers, etc. Basically the user of the server are known as client. The role of server is to share data as well as resources and distribute work. Hardware requirements for servers depends on the it's purpose and software. Rack-Mountable Server Img by-Wikipedia Server Clusters The server clusters is also known as server farm. It is a collection of computer server. Server farm consist of lots of computers which requires lots of energy and cooling system. It also has backup server for the case of primary servers

Daemons are program or process which runs on multitasking operating system lite Unix and Linux. It runs as a background process. The daemons process basically end with letter 'd'. For example syslogd is daemon that implement the system logging facility. Unix and Linux term that describes a program that runs automatically without requiring any user interaction. A Daemon is helps the user by performing tasks commonly done, such as checking for e-mail or in the case of a web server running the HTTP daemon. For example, httpd (Hypertext Transfer Protocol Daemon) runs in the background of a web server under many platforms, including Apache, CERN, and others. It waits for and responds to requests made over HTTP, providing web pages and other files as needed. If you're running a web server and run the top command, you'll see httpd requests as they are being made on the server.

We know that when it comes to Quantum Computing there is amazing things. So, in this post I have written about Quantum memory. The computer whether it is classical or quantum it requires RAM or memory for information processing. In classical computers memory stores information as binary states which is 1 or 0. They are called as bits. The one used in Quantum Computer is called Qubits. Qubits work on the basis of  Quantum Supremacy . The qubits are good for performing quantum logic gate operations. Quantum RAM is necessary for future computers. It will also composed of three basics components memory, input register and output register.  Some team of researchers at Griffith University constructed the proof of principles quantum simulator using a photon a single particle of light interacting with photon. They measured the memory requirements of this simulator and compared it with memory requirements of classical computers. The data showed that quantum system could complete the task with
