Resource Throttling

Resource throttling refers to the artificial cutting down or lowering of the amount of resources or returns in a system. This term is often used to refer to SharePoint features that allow administrators to narrow the results of heavy queries.

There are times when a full system search or other full operation makes too many demands on the system; in this scenario, IT professionals sometimes resort to resource throttling.This will conserve CPU and other resources. IT professionals can also monitor server activity and look for drains on the system. They can then apply resource throttling in order to control resource use on the system and bring it back to manageable levels .

Network Behaviour Analysis

Network behaviour analysis (NBA) is a network monitoring program that ensures the security of a proprietary network. NBA helps in enhancing network safety by watching traffic and observing unusual activity and departures of a network operation.

Network behaviour analysis monitors the inside happenings of an active network by collecting data from many data points and devices to give a detailed offline analysis. It is constantly watching the network, marking known and unknown activities, new and unusual patterns and indicating potential threats by flagging. The program also checks and accounts for change in bandwidth and protocol being used during communication. This is particularly applicable in finding a potentially dangerous data source or website.

The duty of a network behaviour analysis program is to reduce the labour and time expended by network administrators in detecting and resolving network issues. It is thus an enhancement to protect the network along with firewalls, antivirus software and spyware detection tools. Conventional methods of defending a network against harmful data include packet checking, signature recognition and real-time blocking of malicious sites and data.

Google Penguin

Google Penguin refers to a set of algorithm updates and data refreshes that the Google Search Engine periodically releases, that are aimed at improving the value of search query results for users.

This is done to prevent spamming the page index algorithm ( called spamdexing or Black Hat SEO) to prevent irregularities in search results to prevent from being successfully ranked high among query results. Spamdexing can be done by techniques such as Key-stuffing, invisible text display, link-spamming or even displaying copyright items from high-ranking websites and more.

Google Penguin is different from similar enhancement algorithm such as Google Panda and Google Hummingbird such that it not only aims at preventing companies that attempt to “boost” their search engine ranking index but also “penalizing” them.

The first such algorithm published in April 2012 and was estimated to affect 3% of all English-language website.

Business Intelligence

Business Intelligence is the use of computing technologies for the identification, discovery and

analysis of business data such as sales, revenue, products, costs, income, etc. BI provides historical, present and predictive view of internally structured data for products and departments by more effective decision-making and strategic operational insights. BI software applications make use of Data warehouses or Data marts which are separate yet related BI architectural fragments and are used for preparation and use of data.

BI is used for multiple business purposes, including:

• Measurement of performance and benchmarking progress toward business goals
• Quantitative analysis through predictive analytics, predictive modelling, business process modelling and statistical analysis
• Reporting of departmental/divisional and enterprise perspectives of data visualization, EISs and OLAP
• Collaborative programs that allow internal and external business entities to collaborate through electronic data interchange (EDI) and data sharing
• Use of knowledge management programs to identify and create insights and experiences for learning management and regulatory compliance

BI also involves specific methodologies and procedures for implementing such interactive information gathering techniques, including:

• Identifying interview teams
• Researching organizations
• Selecting and preparing interviewees
• Developing interview questions
• Scheduling and sequencing interviews

Spatial Data Mining

An GIS Tool application

Spatial Data Mining Application Example

Spatial Data Mining is the application of Data Mining techniques to spatial models. In Spatial Data Mining, analysts use geographical or spatial information to produce business intelligence or other results. Analysts might be looking into large data bases or extremely large database to find relevant data based on GIS/GPS tools or similar mechanism. The core goal of Spatial Data Mining is to distinguish the information in order to build related, actionable patterns. This requires specific techniques and resources to get geographical data into relevant and useful formats.

TERM OF THE DAY

“Delay tolerant Network”

Delay tolerant networking is built with the dream motive of actuating inter-planetary Internet networking. In general, DTN is used for communications over a vast distance, generally in scales of thousands of kilometres and to overcome the logistical hurdles involved in the same.

Delay-tolerant networking (DTN) is an approach to computer network architecture that seeks to address the technical issues in heterogeneous networks that may lack continuous network connectivity. A delay-tolerant network is a network designed to operate effectively over extreme distances such as those encountered in space communications or on an interplanetary scale. In such an environment, long latency, sometimes measured in hours or days is inevitable. However, similar problems can also occur over more modest distances when interference is extreme or network resources are severely overburdened.

Delay-tolerant networking involves some of the same technologies as are used in a disruption-tolerant network but there are important distinctions. A delay-tolerant network requires hardware that can store large amounts of data. Such media must be able to survive extended power loss and system restarts. It must also be immediately accessible at any time. Ideal technologies for this purpose include hard drives and high-volume flash memory. The data stored on these media must be organized and prioritized by software that ensures accurate and reliable store-and-forward functionality. In a delay-tolerant network, traffic can be classified in three ways, called expedited, normal and bulk in order of decreasing priority. Expedited packets are always transmitted, reassembled and verified before data of any other class from a given source to a given destination. Normal traffic is sent after all expedited packets have been successfully assembled at their intended destination. Bulk traffic is not dealt with until all packets of other classes from the same source and bound for the same destination have been successfully transmitted and reassembled.

Term of the day – “Internet of Things”

Internet of things (IOT) is an umbrella term used to refer all devices that are connected over the Internet . These include PC’s , mobile devices , tablets , etc. Beside computers , these also includes appliances such as micro-ovens , refrigerators , etc . These devices are also called “smart devices” as they can communicate with each other . IOT must be enabled for wireless communication to connect to wired media . Generally these devices use Bluetooth to connect amongst themselves .
Besides communicating and connecting over internet , IOT devices are also with an array of sensors , that can help in multi-faceted applications of the same .
