Describe Internet protocols: IP, TCP, DMP

The Internet Protocol (IP) is the method or protocol by which data is sent from one computer to another on the Internet. Each computer (known as a host) on the Internet has at least one IP address that uniquely identifies it from all other computers on the Internet. This may be either an IPv4 or IPv6 address, but either way it uniquely defines a device on the Internet.

The Internet Protocol also provides basic instructions for transferring packets between devices. However, it does not actually establish the connection or define the ordering of the packets transmitted. These aspects are handled by the Transmission Control Protocol.

Transmission Control Protocol, which works in conjunction with the Internet Protocol to transfer data between systems on the Internet.

Transmission Control Protocol (TCP)

TCP is a connection oriented protocol and offers end-to-end packet delivery. It acts as back bone for connection.It exhibits the following key features:

· Transmission Control Protocol (TCP) corresponds to the Transport Layer of OSI Model.

· TCP is a reliable and connection oriented protocol.

· TCP offers:

o StreamDataTransfer.

o Reliability.

o EfficientFlowControl

o Full-duplexoperation.

o Multiplexing.

· TCP offers connection oriented end-to-end packet delivery.

· TCP ensures reliability by sequencing bytes with a forwarding acknowledgement number that indicates to the destination the next byte the source expect to receive.

· It retransmits the bytes not acknowledged with in specified time period.

TCP Services

TCP offers following services to the processes at the application layer:

· StreamDeliveryService

· SendingandReceivingBuffers

· BytesandSegments

· FullDuplexService

· ConnectionOrientedService

· ReliableService

Specify WEB servicein a cloud technology

Cloud computing is the use of computing (hardware and that are delivered as a network (typical the Internet). The name comes from the use a cloud-shared symbol as an abstraction for the complex infrastructure contains in system diagrams. Cloud computing entrusts remote services with a users data software and computation.

There are many types of public cloud computing.

· Infrastructure as service (IaaS)

· Platform as a service (PaaS)

· Software as a service (SaaS)

· Store as a service (STaaS)

· Security as a service (SECaaS)

The business model using software as a service users also rent application software and databases. The cloud croviders manage the infrastructure and platforms on which the application.

Specify Design and organization of e-learning.

The delivery of a learning,training or education program by electronic means.E-learning involves the use of a computer or electronic device in some way to provide training, educational or learning material.

E-learning can involve a greater variety of equipment than online training or education, for as the name implies, *online* involves using the Internet or an Intranet. CD-ROM and DVD can be used to provide learning materials.

Distance education provided the base for e-learning's development. E-learning can be *on demand*. It overcomes timimg, attendance and travel difficulties.

As you increase the number of eLearning options available for your staff or students, you have probably given much thought to your overall eLearning system design. Having a friendly aesthetic and being easy to use are important features of your learning management system (LMS). Taking the time to set up an interface that works for your learners as well as training coordinators will go a long way toward acceptance and use of your LMS.

 

Elements of information infrastructure of electronic business.

Examples of the e-Technology include e-Commerce, e-Business, e-Procurement and e-Logistics.

Electronic business, or e-business, is the application of information and communication technologies ICT in support of all the activities of business. Commerce constitutes the exchange of products and services between businesses, groups and individuals and can be seen as one of the essential activities of any business.
