Answer 1

1. 404 Host Not Found error message is often generated when attempts are made to access host server with dead, broken link or remote host is not present or moved.

       Some of the reasons for this error are:

• Incorrect URL typed.
• Host is been removed.
• Host is moved but link not changed accordingly.
• Server hosting is not active, not running.
• Connection broken.
• Domain name does not exist.

Errors which are linked with components of TCP/IP communications are:

• Host removed or moved– Contact the website to find if they have changed the host or removed it to find reasons and error corrections. If host is only moved, it can be fixed by getting new web link.
• Connection broken: Try reloading the page using F5 or refresh. Check connection f internet.
• Server hosting is not active, not running: Wait for timings of server activation, if any. Like some websites may have specific business hours. Contact website in case server doesn’t get active.

2. Internet is growing from 16 % in 2005 to 48% in 2015 more and more users are getting added each day. It has transformed business as well. More and more companies, big or small are adding their presence on Internet. They know this media cannot be ignored as it has made easy for business to conduct their businesses.

Some of the advancement which has helped in business is:

• Smartphone: Internet is now in pocket with ease of anywhere connectivity. Businesses are growing with use of smart phones are a media of selling or marketing
• Digital advertizing has outgrown TV or Paper marketing. Companies are targeting users based on their interests, need, requirements and area specific to promote their products.
• 24 x 7 ease: Shops have their own timings, but business on internet can be opened 24 x 7 which is good for customers and increases business.
• Growth of all: big or small everyone can display their products easily without the problem of physical presence. This helps in breaking barrier between big and small companies and also helps in making products available to larger consumers sometimes beyond country boundaries.

• Let’s take an example of retail business which uses internet to do business.

Some of the applications that are part of its core processes that uses internet are:

• Product listing
• Sales
• Customer Information
• Advertising and marketing

Business cannot survive if these core processes are removed as without products there can be no sales. Thus application for core processes is needed for growth of businesses.

4. Emerging technologies such as Internet of things and artificial intelligence will change business. AI will work as personal assistants that will explore the things for customers by collecting data, compare products and may even buy products. This may help in contributing towards growing best businesses.
