The growing potential of quantum computing
The quantum computers have the potential to solve various problems in different industries ranging from financial services to medicine. The quantum computing is based on the integrating of quantum technology in computers. The traditional computers are based on binary system in which the system can be in either of the two binary sates. Contrary to it, the quantum computers uses qubits in which the system can remain in binary state one or two and long with it in states which are the superposition of the above two states. Therefore, it can simultaneously solve logical issue with the configuration of all these qubits. As quantum computers use the application of quantum mechanics, it is important to control the environment in which they are operating. The most prominent feature of the quantum comports is that they are able to conduct complex logical and mathematical calculations at a very high pace. The quantum computers have immense application in pharmaceutical industry and can be used to develop advanced medicines and target lethal diseases. The quantum comport have high applications in machine learning. With the help of quantum computers, the machine learning capability of the devices can increase manifold. The researchers are developing algorithms with the help of quantum computing which can uplift the machine learning capability of the computing devices. Another set of application is in the optimization or sampling. In the scientific field, there are several issues related to optimization of the resources. It can also be used in portfolio analysis and financial service.
The Linux distribution system is the operating system which uses both Linux kernel and package management system as an integral part of their operating system. The Bodhi Linux is a lightweight Linux distribution system which is based on Ubuntu and uses Moksha windows manager as a package system. The ideology behind the development of this Linux distribution system is to provide minimal features to the operating system so that thee users can populate it according to their requirements. As a result, by default the operating system contains software which is most essential for most of the Linux users. These basic features are: file browser, web browser and terminal emulator. The software developers also provide online database of lightweight applications and software which can be instantly installed in Bodhi Linux operating system. There is standard version of Bodhi Linux which can be used for Intel-compatible processors. In addition to it, an alpha release version is also released which can run on Debian operating system. Bodhi Linux is derived from Ubuntu long term support releases; therefore, it provides several features such as security bug fixes which are released on a very frequent basis. Bodhi has no short term support in contrast to Ubuntu. The Bodhi Linux can be upgraded to latest version with the package manager.
Welcome to VirtualBox.org
The Oracle VM VirtualBox is an open-source and free hypervisor developed by the Oracle corporation. With this software, a large number of virtual machines can be developed which can run simultaneously on a single machine. The virtual machines can run on different operating systems such as Windows, Linux and other operating system. In order to make the hosted virtual products compatible with other operating systems, a “guest additions” package is installed which supports the device drivers and provide different system application. Additional applications are provided to improve the performance of the operating system. The users of VirtualBox can load a large number of guest operating system in a single host operating system. All the guest operating system can initiate, pause and stopped independently. They have their own memory management and resource allocation system. The users can also independently configure their virtual machine and can run the machine as software-based virtualization or hardware-assisted virtualization. Moreover, in this software, different virtual machines can communicate with each other through different mechanisms. It has several distinguished features, such as 64-bit guest machine can run on it with the hardware virtualization support. It also provides seamless mode wherein a several large number of applications can run side by side.
SCTP (Stream Control Transmission Protocol).
The Stream Control Transmission Protocol (SCTP) is a transport-layer protocol which is similar to the more popular protocols such as TCP and U. It has similar features as UDP and TCP as it is message-oriented and ensures reliability. It also provides in-sequence transport of messages which increases the congestion control of the network. Moreover, in order to increase the resilience and reliability of the protocol, it provides multi-homing and redundant paths to data packages. If SCTP support is not available in the network, the SCTP can be tunneled over UDP. TCP can also be mapped over SCTP to add on the additional features of the SCTP. The current version of SCTP design has several features to enhance the security of the system such as encryption and multi-hoping. It also has 4-way handshake in contrast to TCP 3-way handshake which protects the computing system from SYN flooding attacks and provide large cookies for verification and authenticity. Multi-homing is the method to keep the network updated even when some routes or interfaces in the network are down. The SCTP can be used in firewall and intrusion detection. It provides strong resilience to the telecommunication network even in case of network anomalies.
What is WannaCry and how does ransomware work?
Wannacry ransomware is a recent attack on the IT world wherein the attackers infected the computer systems of more than one fifty countries. A large number of computer systems were attacked with the ransomware. It worked similar to other ransom software in which the users are blocked access to the computer system until they pay ransom amount.
A large number of business organizations, healthcare organization and banks were infected by the ransomware. The NHS in England was also infected by the virus. In this ransom attack, the hackers enter the computer system and decrypt a significant amount of data and files. Then after, the hackers publish a message in which the owners of the systems have to publish the pay the ransom amount, otherwise the crucial data of the organization will be lost. The ransom amount needs to be paid in bitcoin which is cryptocurrency. The attack was heavily criticized by the international media as the vulnerability was already identified by the US intelligence agency; however, instead of notifying Microsoft, the organization made its own offensive mechanism. The worm uses EternalBlue method to enter the computer system and then the malware uses DoublePulsat to transmit in the network. It scans the network for vulnerable computing devices and attacks the systems which do not have latest software version or windows update.
Data center disaster disrupts Delta Air Lines.
The data center fires are a significant issue in the IT world. Regularly, a large amount of data and information is lost due to fires in data centers. Today, all the companies are using electronic mediums to store and save data and information. Therefore, any malfunctioning in database of the organization can cause huge dent to the business of the organization. The data center fire can cause due to temperature increase of the server room or malfunctioning of system or software issues. The primary reason of the data center fires is excessive heat generated due to excessive heat generated by the system. In 2016, the data center fire occurred in the database of US Airline Delta which disturbed the flight schedule of the airlines. Several customers have to wait in queue for the flight to arrive. A large number of flights were delayed due to the technical error. The data centers store the crucial information and data of the organization. It involves several crucial information of the organization such as flight schedule, flight bookings, and customer information. Any issues in the data center of the organization can halt its operations. Data center flights also cause damage to the reputation of the organization and increases customer dissatisfaction. The blaze emerging from the data center can cause infrastructural damage to the organization. Big companies implement several measures to control the temperature of data center rooms. The companies can implement different software for controlling the temperature of the data center rooms. The software can raise an alarm if the temperature of the data center rooms rise above a threshold level. The authority can shut down the data server until the temperature goes below the risk level.

They failed to analyze the application of the different products and how to maintain customer base by analyzing the customer base.
Why Target failed in Canada.
Target Corporation is one of the leading retail organizations in the USA. It is the second largest retail market after Wal-Mart in the USA. When the market of the company becomes saturated and slow in the USA, it planned to expand its business in Canada. It was a prospective option as a large number of people cross borders to shop from the retail outlets in the USA. However, the company failed to develop a successful business model in the country. It was presumed that the customers will be attracted towards discount. However, the company did not provided significant difference in the price in comparison to the local competitors. Moreover, the organization launched its venture in Canada abruptly which create several supply chain issues in the organization. The company made substantial financial investment by buying a large number of retail outlets of the local competitors. It was presumed that the organization will be able to reduce the competition as well as gain well-developed infrastructure after buying these outlets. However, there was lack of market research as the company advertised that the organization will sell products at low cost but there was marginal difference between the prices of the products. The customers who came to buy the products from the organization were also dissatisfied due to limited product offerings of the company. It was due to the mismanagement of the supply chain. It can be critiqued that the organization failed in the business venture and lost significant amount of money.
