Answer:-
DNS:- DNS stand for Domain Name server.It is a hierarchical naming system for computers, services, or any resource connected to the Internet.DNS make us very easy to know the address of each and every website by name conversion instead of dotted decimal notation.For example, on the web, it's much easier to remember the domain name www.amazon.com than it is to remember its corresponding IP address (207.171.166.48). DNS allows you to connect to another networked computer or remote service by using its user-friendly domain name rather than its numerical IP address.
DHCP:- DHCP stand for Dynamic Host Configuration Protocol.It is a computer networking protocol used by hosts to retrieve IP address assignments and other configuration information.It provides dynamic IP address to all the host computers.We don't need to configured individually in manually. In some systems, the device's IP address can even change while it is still connected. DHCP also supports a mix of static and dynamic IP addresses DNS is features of IP that resolves domain names into actual IP address and
DHCP is a protocol that automatically assign the IP address and configures to all the host computers.
2. Why it is important for your online business application to use a static IP address rather than have it dynamically assigned?
Static IP addresses are important for sites such as ecommerce sites where security and confidential information and data would be an issue. It is essential for sites such as these to use static IP addresses if they are going to use SSL encryption. SSL encryption is required in order to make sure that any confidential data travelling to and from site is encrypted. This stops any of this data from being seen by the wrong person.
One other reason for using a static IP address is that it is required for ftp transfers. If we are allowing visitors to our site to download files then we must have a static IP address. That is why many people prefer to use static IP addresses.
3.What role can the following play in business-to-business e-commerce?
a. Virtual Private Network(VPN) or Grid computing service
Virtual private Network tunnels have long been used to provide confidentiality and integrity for data over untrusted networks like the Internet. Today, many companies use tunnels to secure traffic from remote workers to a VPN gateway at the edge of the company network. That gateway is responsible for authenticating users and controlling which destinations can be reached.Some examples of tunnel standards are There are many VPN tunneling standards, including the Point-to-Point Tunneling Protocol (PPTP), Internet Protocol Security (IPsec), and the Secure Sockets Layer protocol (SSL).
b. Next Generation of wireless mesh networks
The role of wireless mesh Networks in B2B e-commerce are as follows:-
1.Decreased need for Internet gateways
2.Collaborative redundant backup technology, which insures data security in the event of disk failure
3.The ability to configure routes dynamically
4.Lower power requirements, which could potentially be met by low-cost or renewable energy sources
5.Increased reliability: Each node is connected to several other nodes and if one drops out of the network, its neighbors simply find another route.
c. Cloud or social cloud applications

c. Cloud or social cloud applications
Cloud application is popular in B2B e-commerce.Because cloud application reduce the cost of hardware,software,storage devices and so on.These days we can backup all the data and information in could application.Cloud application have their own huge hardware in server side.Thats why we don't need to tension about this problem.To use the application we just simply need the internet connection and have their(customers) own user-name and password to enter into the business application.
This obviously reduce cost,user-friendly, will be more scalable, secure and reliable as well.Instead of using these application,the business owner have to pay certain monthly fee.

4. If clouding computing is the "Black Box”, then grid computing is a component as the white box. Explain what you interpret about that statement.
Answer:-
The cloud computing is called Black Box because the technology infrastructure is abstract from the user. And the user shouldn’t be expert to use the resources and information for the internet. In other word it is also called the abstraction between computing resources and the underlying technical architecture.” Web 1"
And grid computing is a component as the white box because it shares the group of computer infrastructure to solve a complicated task. Grid may be dedicated to a specialized application. And they are a form of distributed computing, which has some degree of control over the computer infrastructure to achieve a common goal. “Web 2"
