Information Technology Essay

Q. Not any 1 .

Explain the following:

we. Web Browser

2. M-Commerce

3. Electronic Pay for Transfer ( EFT)

I) Web Browser: An online browser (commonly referred to as a browser) is actually a software application for retrieving, showing and crossing information solutions on the World Wide Web. An info resource can be identified by a Uniform Resource Identifier (URI) and may be a web page, picture, video or other article.[1] Hyperlinks present in resources permit users easily to navigate their internet browsers to related resources. Even though browsers happen to be primarily designed to use the Internet, they can end up being used to gain access to information furnished by web machines in exclusive networks or perhaps files in single file systems. The main web browsers happen to be Google Chrome, Firefox, Internet Explorer, Internet explorer, and Safari.[2] II) M-Commerce: Mobile Commerce, or m-Commerce, is about the explosion of applications and services which might be becoming attainable from Internet-enabled mobile devices. It involves new technologies, companies and organization models. It is quite different from traditional e-Commerce. Mobile phones impose different constraints than desktop computers. But they also available the door into a slew of new applications and services. They will follow you wherever going, making it possible to look for a nearby restaurant, stay in touch with acquaintances, or spend on items at a store. iii) Electronic money transfer (EFT) is the electronic exchange, transfer of money from account to another, either in a single standard bank or throughout multiple corporations, through computer-based systems. Electronic Funds Copy (EFT) provides for electronic obligations and choices. EFT is secure, secure, efficient, and less expensive than conventional paper check payments and collections. While it costs the U. S. federal government $1. 03 to issue each verify payment, that costs simply 10. 5 cents to issue an EFT payment. What is WEB ADDRESS?

A homogeneous resource locator, abbreviated WEB LINK, also known as website, is a particular character line that constitutes a reference to a resource. In most web browsers, the Link to a web webpage is viewed on top inside an address bar. An example of a normal URL will be " http://en.example.org/wiki/Main_Page". A URL is theoretically a type of consistent resource identifier (URI), in many technological documents and verbal discussion posts, URL can often be used like a synonym pertaining to URI, which is not considered a problem.[1] Question-3 Several between the next:

Question No-3:


a) bus network and engagement ring network

b) circuit moving over and box switching

c) software paperwork and program design records

d) Unnatural intelligence and expert system

Bus network and ring network

In a ring topology, the nodes are linked in a engagement ring and info travels in one direction utilizing a control signal called a 'token'. Advantages:

• Not really greatly troubled by adding further nodes or heavy network traffic since only the node with the 'token' can transmit data therefore there are simply no data accidents. • Comparatively cheap to put in and expand.


• Slower than the usual star topology under normal load.

• If the cable television fails any place in the band then the entire network will certainly fail. Coach (line) topology:

Nodes happen to be connected to a main (bus) cable television. If info is being dispatched sent among nodes then other nodes cannot transmit. В In the event that too many nodes are connected then the transfer of data slows dramatically while the nodes have to hold out longer to get the shuttle bus to be clear. Advantages:

a) The easiest and most affordable to install and extend.

b) Well suited for short-term networks with not many nodes. Disadvantages:

a) If the bus cable falls flat then the entire network is going to fail. b) Performance in the network decelerates rapidly with additional nodes or heavy network traffic. B. Circuit Transitioning:

1 . ) In circuit switching, there are numerous nodes utilized in the network through which the signals are passed in one system to another. 2 . ) In this a number of...
