What is a web server?

ANSWER:

Web server web server is a machine that serves up the web page requests of a client on the internet. It is a combination of hardware and software.

So, transaction processing sites generating dynamic pages with high traffic volumes would need web server software that is more efficient and can easily be upgraded.

Packet filter firewall

It uses a set of rules to determine whether outgoing or incoming data packets are allowed to pass through

Circuit level firewall

It is quite similar to the packet filter firewall. It also works on the basis of a set of rules for filtering packets

but operates at the transport layer of the OSI Model so has greater functionality.

Application gateway firewall

It operates at application layer of the OSI Model. It uses strong user authentication to verify identity of a

host attempting to connect to the network using application layer protocols such us FTP. In contrast to

packet filter firewall, it filters the requests rather than packets entering/leaving the network. It can block

any outgoing HTTP or FTP requests.

Answer : Web server – machine that services internet request.

Web server – machine that services internet request

web server is a machine that serves up the web page requests of a client on the internet. It is a combination

of hardware and software. Decision as regards the type of a web server is largely dependent on the volume

and type of web activities. So, transaction processing sites generating dynamic pages with high traffic

What does „parseFloat(string)‟ And NaN mean?

The parseFloat() function parses a string and returns a floating point number. This function

reaches the end of the number, and returns the number as a number, not as a string.

The NaN property represents "Not-a-Number" value. This property indicates that a value is not a

legal number.

How „Man in The middle Attacks‟ operates?

Man in the middle attacks

In it the attacker is able to monitor, capture and control data between sending and receiving

machines. He may apply IP address spoofing technique to divert the packets to its machine, then

modify the packets and resend the misleading information to the actual client. Another form of man-

in-the-middle attack is where the hacker is able to substitute the IP address of a genuine web site

with the IP address of his own web site due to some security hole in the software that runs on a

domain name server. A client would think that he is communicating or receiving the information

form a genuine web site, though it would not be the case actually.

Differentiate between front end and back end.

Answer: Front end consists of that information which is visible to the user and he can interact with

the same through some interface. The back end comprises that information which resides on the


server side and is used to create certain dynamic results for the user. It would include different

programs or scripts that may be developed in different languages/tools. Backend is mainly used for

two purposes – for querying with the databases and for the maintenance of state. We can use

different tools (ASP, JSP etc.) for that purpose depending upon their respective

advantages/disadvantages.

What do you think, is there any difference between Static and Dynamic IP Address assignment? Discuss.

A static IP address is an address that does not change over time unless changed manually. It is used when you need the IP address or network location to remain the same consistently. A good example of this is for a web server. If you go to www.google.com you are really going to the IP address of 66.102.7.99. If this were to change suddenly you would not be able to get to Google unless you knew the new IP address or until Google updated their DNS records.

A Dynamic IP address is an address that keeps on changing. It is mostly used when having a consistent IP address is not necessary. An example of this would be the IP address your ISP (internet service provider) assigns you when you log on to the internet. You must have an IP address to surf the web but once you disconnect you loose that address. Then the next time you sign on you are assigned a new one. This is done using DHCP.


What is cryptography? What techniques are used for cryptography?


Cryptography is the technique of converting a message into unintelligible or non-understandable form such

that even if some unauthorized or unwanted person intercepts the message he/she would still not be able to

make any sense out of it. Cryptography is thousands of years old.

Techniques used for cryptography Substitution In substitution we replace each letter in the message with

another to make the message non-understandable. For example, each letter “a” in the message can be

replaced with letter “d” and letter “b” with letter “e” and so on. Transposition It is based on scrambling the

characters in a message. A transposition system may first write a message into a table row by row then the

message can be read and rewritten column by column to make it scrambled.

Describe the importance of Cryptography in internet data transfer security in E-Commerce?

It is a collection of mathematical techniques used to ensure confidentiality of information. The

process of scrambling a message with the help of a key is called Encryption.

Now a days as internet is widely used. So danger of data safety and serurity also rose. Compare to its

earlier use.

It provide the Transaction Integrity. Tranasction detail of both the parties can be verified which

help to built the confidence between business community.

It provide Privacy like it provide controls to prevent third parties from geting access to the

information within the transaction


Without cryptography, it is doubtful that banks, businesses and individuals would feel safe doing

business online.

Cryptography provides the confidence to the customer that their data is safe and secure. Otherwise

due to lack of confidence and doubt e-commerce business can not flourish.
