E-Commerce Presentation Transcript:
1. WHAT IS E-TRADING ?
THE MARKETING BUYING AND SELLING OF PRODUCTS AND SERVICES ON THE NET . IT BRINGS THE UNIVERSAL ACCESS OF THE NET TO THE CORE BUSINESS PROCESSES OF BUYING AND SELLING OF GOODS AND SERVICES.

2. E-COMMERCE ENABLES ORGANISATIONS TO ACCOMPLISH THE FOLLOWING GOALS: REACH NEW MARKETS CREATE NEW PRODUCTS AND SERVICES BUILD CUSTOMER LOYALTY ENRICH HUMAN CAPITAL MAKE THE BEST USE OF EXISTING AND EMERGING TECHNOLOGIES ACHIEVE MARKET LEADERSHIP AND COMPETETIVE ADVANTAGE

3. ADVANTAGES OF E-COMMERECE
LOWER COST ECONOMY HIGHER MARGIN BETTER CUSTOMER SERVICE QUICK COMPARISION SHOPPING PRODUCTIVE GAINS MARKET KNOWLEDGE TEAM WORK INFORMATION SHARING CONVINIENCE

4. LIMITATIONS OF E-COMMERCE SECURITY
E- COMMERCE IS NOT FREE CUSTOMER RELATION PROBLEM PRODUCTS PEOPLE WON’T BUY ONLINE CONSUMER SEARCH IS NOT EFFICIENT SYSTEM SCALABILITY

5. DEBIT CARD
A KIND OF PAYMENT CARD THAT TRANSFERS FUND DIRECTLY FROM THE CUSTOMERS BANK ACCOUNT TO THE MERCHANT CREDITCARD A PLASTIC CARD WITH A PRE-ARRANGED SPENDING LIMIT BASED ON THE CREDIT CARD HOLDER’S CREDIT RATING,EMPLOYMENT RECORD ETC. SMART CARD A CARD WITH A BUILT IN CHIP CAPABLE OF STORING INFORMATION IN ITS MEMORY . E-CASH ,DIGI CASH, E-WALLET E-CASH IS AN ELECTRONIC MEDIUM FOR MAKING PAYMENT. E-WALLET IS AN ELECTRONIC PAYMENT SYSTEM THAT OPERATES LIKE A CARRIER OF E-CASH AND INFO IN THE SAME WAY A REAL WORLD WALLET FUNCTION.

6. VALUE CHAIN IN E-COMMERCE

Wireless Sensor Networks Presentation Transcript:
1. INTRODUCTION WSN
are used to collect data from the environment. They consists of large number of sensor nodes and one or more Base Stations. The nodes in the network are connected via Wireless communication channels. Each node has capability to sense data, process the data and send it to rest of the nodes or to Base Station. These networks are limited by the node battery lifetime.

2. ADVANTAGES
It avoid lot of wiring. It can accommodate new devices at any time. Its flexible to go through physical partitions. It can be accessed through a centralised monitor.

3. DISADVANTAGES
It is very easy for hackers to hack it as we cant control propagation of waves. Comparitively low speed of communications. Gets distracted by various elements like Blue-tooth. Still costly at large.

 4. Sensor node functionality
Each sensor node contains a computational module (a programmable unit) which provides computation ability, storage, and bidirectional communication with other nodes in the system Two advantages: They can be re-task in the field Easily communicate with the rest of the network

5. Gateway
Each sensor patch contains a gateway node Each gateway node can communicate with the sensor network and provides connectivity to the transit network

6. Transit Network
Can consist of a single hop link or a series of networked wireless nodes Each transit network design has different characteristics Robustness Bandwidth Energy efficiency Cost Manageability

7. Base Station
Data storage for the collection of sensor patches WAN connectivity will be wireless Base-Remote link connection to the internet

8. WSN PROTOCOLS
Wireless sensor network routing protocols can be classified into following categories. Direct communication Flat protocols (Multihop) Hierarchical Routing Protocols

9. Applications of WSN
Environmental/Habitat monitoring Acoustic detection Seismic Detection Military surveillance Inventory tracking Medical monitoring Process Monitoring

Fiber Optics Presentation Transcript:
1. HISTORY
It began about 40 years ago in the R&D labs (Corning, Bell Labs, ITT UK, etc.) first installed commercially in Dorset, England by STC and Chicago, IL, USA in 1976 by AT&T. By the early 1980s, fiber telecommunications networks connected the major cities . Modern fiber-optic communication systems generally include an optical transmitter to convert an electrical signal into an optical signal to send into the optical fiber. The information transmitted is typically digital information.

2. Why Optical Fibers ?
As mans need for communication increased, the amount of bandwidth required increased exponentially. Initially we used smoke signals, then horse riders for communicating. But these ways were way to slow and had very little bandwidth or data caring capacity. Optical Fiber,~ the diameter of human hair, can carry 5,00,000 circuits of voice and data. This capacity is increasing day by day as supporting electronics is developing.

3. The light source (LAZER) at the transmitting (Tx) end is modulated by the electrical signal and this modulated light energy is fed into the Optical Fiber. At the receiving end (Rx) this light energy is made incident on photo-sensors which convert this light signal back to electrical signal.

4. Telecommunications
Internet Access Cable and Satellite Television Decorative Light Source

5. Components
Cladding-cover with a protective or insulating layer of other material

6. Characteristics
Glass Core Glass Cladding Ultra Pure Ultra Transparent Glass Made Of Silicon Dioxide Low Attenuation Popular among industries

7. VARIOUS TYPES OF OPTICAL FIBER CABLES
OPGW Cable ADSS type OF Cable Self-Support AERIAL figure 8 type OF Cable LASHED type OF Cable UNDERGROUND / BURRIED type OF Cables DUCT Type OF Cable

8. Fiber Optic Connectors
Since fiber optic technology was introduced in the late 70s, numerous connector styles have been developed - probably over 100 designs. Each new design was meant to offer better performance

9. Types Of Fiber Optic Connectors
The ST/SC connectors about 0.1 inch - so they can be mixed and matched to each other Volition is a simple, inexpensive duplex connector It aligns fibers in a V-groove like a splice.
