What is E-Group

E-Groups are a list of emails, users that can share information among each other. A single administrator can maintain that group and hence provide the entire set of users to communicate between each other. You can think of the administrator as a person who is controlling the E Group. For example most of the companies these days have an E Group structure where all employees can send email to each other, share files and access folders on their servers or view each other’s calendar. The important fact is that only the users within the group have the access and any user who is not in the group will not get the permission to access.

The administrator of the group has the control on what level of access can the different users have. Mostly all users can send an email to each other, but some users may have access to all the files that the organization stores while others only to a specific folder.

What is Social Networking

Social Networking is a platform that helps people to connect with others and build a social relation. The last 15 years has seen a splurge of social networking sites where people can search / choose to make friends, post pictures and photos, comment on each other’s activities. Social networking has opened the doors where people can connect and share their lives and the activities by them without being close geographically. People can connect from anywhere in the world with the internet connection. They can become the member of one or other available social networking site.



Social networking site allows a user to share ideas, activities, events, and interests among the people. The individuals can also have the control of the content they share and the person with whom they are or want to communicate with. An individual can share text information, photos, data files or even videos. Many people now days use social networking sites to market their business and thus reach the potential customer. Using an account of these sites they can showcase their product and services that the people interested can follow and review.

What is E-Shopping

E-Shopping
On-line shopping is the purchase of products and services over the Internet using a desktop or laptop of other smart device. With the access of Internet everywhere On-line shopping is gaining popularity as it is convenient to fast paced life style of the people these days.

More and more business firms are offering these opportunities because it also helps them to reduce the infrastructure costs setting up stores, hiring sales employees and merchandising. Products such as clothes, shoes, groceries, books and larger products as furniture and home décor are offered through online shopping.

Benefits of E-Shopping:
1. Reduces time for customers as they can do a search from the comfort of their home and compare prices
2. Reduces major infrastructure cost to the businesses
3. Helps move products faster as the products move from manufacturer to the customer skipping unnecessary storage.
4. Businesses benefit from immediate funds availability and mostly customers pay for the product through e-payment online.

Disadvantages of E shopping:
1. Customers are not able to touch and feel the products
2. Businesses have to manage the logistics of delivering products just-in-time
3. The access of this shopping depends entirely on availability of Internet. This limits a large population who does not know to use the technology i.e. the remote areas.
4. Businesses have to continually protect against fraud and returning of the products sold.

There are several e-shopping portals available worldwide. Some of them are local to a specific region or country. Some portals provide with a global access. The examples of such portals are e-bay, amazon etc. In India there are other established e-shopping portals such as Home Shop 18, Naaptol .com, Yebhi.com etc…

The most important interface components of E-Shopping portal are:
1. Customer website interface
2. Order management and inventory control.
3. Shipment Interface with various logistics organizations
4. Payment gateway for financial interface for payment processing
5. Customer service and support with live agents for complaints and help

E-Shopping has not only changed the way consumers are shopping for the products but has also changed how the product moves from manufacturers to the end user. In the typical store-shopping model, the product moved from manufacturer to wholesalers to several intermediaries and finally to stores where customer may buy it. This model had several layers of transportations built in leading to costs. In the e-shopping model, the E-Shopping portal manages just-in-time inventory where product is obtained from manufacturer after the customer orders it from the website. This product is then shipped directly from the warehouse of the shopping portal provider to customer. This eliminates the intermediary and hence saves the cost of middleman.

What is E-Learning

E-Learning
As computer and usage of Internet has made the life of the business people easy, companies from across the world have started to consider the fact that information and knowledge can be imparted to people using technology. E-Learning is one such method in this direction.
The E-Learning is a method of providing guidance and/or delivering information to students of university or the employees of companies. Several universities and companies design the courses that can be reviewed using laptop, desktops or other smart devices. These programs are developed in such a way that the individuals don’t need to come to a classroom but can review all the data from any place convenient to them. It can be their home or their office. Such courses are designed in such a way that people can progress slowly or at a pace, they can manage. These courses help an individual to assess their knowledge online. This is done using the built in evaluation tools like quizzes or multiple choice questions. These courses are sometimes, stored in a directory or a server, from where the students can access and copy them on the compact disc or other data storage device. In either case, the program is developed in such a way that the student needs minimal interaction with a human tutor to understand the information being shared.

The biggest advantage of E-learning is that it helps to provide information to a large group of individuals who cannot attend an institution. It also reduces the need for one to go to a specific place to learn or to share information. The E- Learning provides an opportunity to the student to complete the course at their speed. Several product development companies develop programs for E-learning the business in schools and universities. Today even a young child from an elementary school knows how to use a smart device, a device that helps in interactive learning. The universities from across the globe keep offering the on-line courses. This is possible through e-learning. The e-learning may even provide the students a platform to share their thoughts and have live or online discussions for clarifications.
The following are the advantages of online or computer-based learning:
1. Class work can be scheduled around work and family.
2. Reduces travel time and travel costs for off-campus students.
3. Students may have the option to select learning materials that meets their level of knowledge and interest.
4. Students can study anywhere; they only need access to a computer and Internet Connection.
5. Self-paced learning modules allow students to work at their own speed.
6. Flexibility to join discussions in the bulletin board threaded discussion areas at any hour, or visit with classmates and instructors remotely in chat rooms
7. E-Learning can accommodate different learning styles and facilitate learning through a variety of activities
8. Develops knowledge of the Internet and computer skills that will help learners in their career.

Disadvantages of online or computer-based learning
1. Learners with low motivation or bad study habits may fall behind.
2. Without the routine structures of a traditional class, students may get lost or confused about course activities and deadlines.
3. Students may feel isolated from the instructor and classmates.
4. Instructor may not always be available when students are studying or need help.
5. Slow Internet connections or old computers may make accessing course materials frustrating.
6. Managing computer files and online learning software can sometimes seem complex for students with beginner level computer skills.

7. Lab work is difficult to simulate in a virtual classroom.

Swarm Intelligence

Swarm intelligence (SI) originated from the study of colonies, or swarms of social organisms.
Studies of the social behavior of organisms (individuals) in swarms prompted the design of very efficient optimization and clustering algorithms. For example, simulation studies of the graceful, but unpredictable, choreography of bird flocks led to the design of the particle swarm optimization algorithm, and studies of the foraging behavior of ants resulted in ant colony optimization algorithms.
            Particle swarm optimization (PSO) is a stochastic optimization approach, modeled on the social behavior of bird flocks. PSO is a population-based search procedure where the individuals, referred to as particles, are grouped into a swarm. Each particle in the swarm represents a candidate solution to the optimization problem. In a PSO system, each particle is “flown” through the multidimensional search space, adjusting its position in search space according to its own experience and that of neighboring particles. A particle therefore makes use of the best position encountered by itself and the best position of its neighbors to position itself toward an optimum solution. The effect is that particles “fly” toward an optimum, while still searching a wide area around the current best solution. The performance of each particle (i.e. the “closeness” of a particle to the global minimum) is measured according to a predefined fitness function which is related to the problem being solved. Applications of PSO include function approximation, clustering, optimization of mechanical structures, and solving systems of equations.
Studies of ant colonies have contributed in abundance to the set of intelligent algorithms. The modeling of pheromone depositing by ants in their search for the shortest paths to food sources resulted in the development of shortest path optimization algorithms. Other applications of ant colony optimization include routing optimization in telecommunications networks, graph coloring, scheduling and solving the quadratic assignment problem. Studies of the nest building of ants and bees resulted in the development of clustering and structural optimization algorithms.
