ASYNCHRONOUS COMMUNICATION

Asynchronous communications is the method of

communications most widely used for PC

communications.

Through asynchronous communications, data istransmitted one byte at a time with each byte

containing one start bit, eight data bits, and one

stop bit, thus yielding a total of ten bits.

The asynchronous communication technique is a

transmission technique which is most widelyused by personal computers to provide

connectivity to printers, modems, fax machines,

etc.


27/41

SYNCHRONOUS COMMUNICATION

Through synchronous communications, data is

transmitted as frames of large data blocks rather

than bulky individual bytes.

Advantage of synchronous is that it is moreefficient than asynchronous.

Some examples are e-mail messages, discussion

boards, blogging, and text messaging over cell

phones.


28/41

DIFFERENCE BETWEEN SYNCHRONOUS ANDASYNCHRONOUS COMMUNICATION

It is based on

synchronization between the

sender and the receiver

This communication doesn't

need any synchronization

between the sender and the

receiver

Both must be synchronized

before actual communication

takes place

Sender may send the information

at anytime without waiting for

the receiver to be ready to receive

the information

in synch comm between two

nodes, first connection will be

established and the

communication will take place

in asynch comm there is no need

to establish a connection before

data transmission

Q3]A) COMPUTER VIRUSES

oA computer virus is a small software

program that spreads from one computer to

another computer and that interferes with

computer operation. A computer virus may

corrupt or delete data on a computer, use

an e-mail program to spread the virus to

other computers, or even delete everything

on the hard disk.


30/41

TYPES OF COMPUTER VIRUSES

y Boot sector virus

y Browser highjacker

y Direct action viruses

y File infected viruses

y Macro viruses

y Multi partite viruses

y Resident viruses


31/41

Q3]B)DECISION SUPPORT SYSTEMS

oAdecision support system (DSS) is a

computer-based information system that

supports business or organizational decision-

making activities. DSSs serve the

management, operations, and planning

levels of an organization and help to make

decisions, which may be rapidly changing

and not easily specified in advance.


32/41

Q:3(C) PROTOTYPING APPROACH AND ITS

PROS AND CORNS

Prototyping is the process of building a

model of a system. In terms of an

information system, prototypes areemployed to help system designers build an

information system that intuitive and easy

to manipulate for end users.

Prototyping is an iterative process that ispart of the analysis phase of the systems

development life cycle.


33/41

Pros

Reduces development time.

Reduces development costs.

Requires user involvement.

Developers receive quantifiable user feedback.

Facilitates system implementation since users know

what to expect.

Results in higher user satisfaction.

Exposes developers to potential future system

enhancements.


34/41

Cons

Can lead to insufficient analysis.

Users expect the performance of the ultimate system

to be the same as the prototype.

Developers can become too attached to their prototypes Can cause systems to be left unfinished and/or

implemented before they are ready.

Sometimes leads to incomplete documentation.

If sophisticated software prototypes (4th GL or CASETools) are employed, the time saving benefit of

prototyping can be lost.


35/41

Q:3(D) PUBLIC KEY INFRASTRUCTURE

PKI is a security architecture that has beenintroduced to provide an increased level of confidencefor exchanging information over an increasinglyinsecure Internet.

A PKI including the use of encryption, digital

signatures, public keys, private keys, digitalcertificates, Certificate Authorities, certificaterevocation and storage. A PKI infrastructure isexpected to offer its users the following benefits:

certainty of the quality of information sent andreceived electronically

certainty of the source and destination of thatinformation

certainty of the privacy of that information

WHAT DO YOU UNDERSTAND BY E-BUSINESS ?

Electronic Business is commonly defined as e-

business is the conduct of business on the

internet ,not only buying and selling of goods

and services but also servicing customers andcollaborating with business partners and

conducting electronic transactions within an

organization.

One of the best examples of e-business isAmazon n e BAY


37/41

CONT.

E-business can be conducted using the web andthe internet.

Virtual Organization

Eg- ebay

Click and Mortar OrganizationsEg- Walmart

E-business covers the entire business process:

Electronic purchasing and

supply chain management, processing orders

electronically which involve online payment via

credit cards or debit cards, handling customer

service.


38/41

E-BUSINESS HELPS WITH REAL

LIFE BUSINESS:

Cut costs and transaction times

Save time and money by improving

internal and external functions

Promote, market and sell around the

world around the clock through a website

Improve customer support,communication and relationship

management

Compete globally without setting offices


39/41

Q5]IN EXCEL,

WHAT IS MEANT BYGOAL SEEK? EG?

Goal Seek is part of a suite of commands sometimes called what-if

analysis tools. When you know the desired result of a

single formula but not the input value the formula needs to

determine the result. When goal seeking, Microsoft Excel varies

the value in one specific cell until a formula that's dependent on

that cell returns the result you want.


40/41

GOAL SEEK

For example, use Goal Seek to change the

interest rate in cell B3 incrementally until the

payment value in B4 equals $900.00.
