Computer Internet Questions and Answers

Answer: A

The first page is called the home page.

A website's home page is its main or front page, the one displayed when a user enters the site's address, usually holding the site's title, navigation menu and links to its other pages. The term is also used for the page a browser opens at start-up.

'Browser page' and 'search page' are not the standard names for it; a search page is a page of search results or a search engine's page. A bookmark is a saved link to a page that a user wants to return to, not the page displayed first.

Answer: B

The answer is Portal.

A web portal is a website that acts as a gateway to a wide range of information and services from one place: a search facility, e-mail, news, share prices, weather, sports, entertainment and links to other sites. Yahoo!, MSN and Rediff are classic examples, and governments run portals that bring their online services together.

A hostel is a place to stay, an article is a single piece of writing, and a newspaper provides news but not search capabilities or e-mail, so none of them offers the combination of services described.

Answer: C

The component that is not essential is the telephone.

A video-conferencing system needs a video camera to capture the picture, a microphone to capture sound, a display device to show the other participants, speakers, and a network connection with suitable software or a codec to carry the audio and video between the sites.

A telephone is not needed, since the sound travels with the video over the network, through the system's own microphone and speakers. Video camera, display device and microphone are all essential, so they are the wrong answers.

Answer: A

Kurrently is a/an Search Engine.

Kurrently was a real-time search engine that searched public posts on social networks such as Facebook and Twitter as they appeared.

It searched social networking sites but was not one itself, and it was neither a blog nor an internet forum.

Real-time search engines of this kind index posts as they are published, rather than crawling web pages periodically as general search engines do, which is why they were useful for following breaking news on social media.

Answer: A

The founder of Twitter is Jack Dorsey.

Twitter was created in 2006 by Jack Dorsey together with Noah Glass, Biz Stone and Evan Williams; Dorsey sent the first tweet and is the name usually given as its founder.

Mark Zuckerberg founded Facebook, John McCarthy was a pioneer of artificial intelligence, and Fred Cavazza is a French writer on social media.

Dorsey later served as the company's chief executive for two periods and went on to found the payments company Square (now Block).

Answer: B

The database is called the Domain Name System.

The Domain Name System (DNS) is the distributed, hierarchical database of the internet that maps host names such as www.example.com to IP addresses. Root, top-level-domain and authoritative name servers each hold part of it, and resolvers query them in turn.

'Domain Name Service' is a loose expansion of the same acronym but not the name of the system. 'DNS File System' does not exist, and 'none of the above' is wrong because the answer is listed.

Answer: C

The model is C2B.

In consumer-to-business (C2B) commerce the consumer creates the value or sets the terms and the business responds. A 'name your own price' site, where the buyer states the price and sellers accept or decline it, is the standard example.

In B2B one business sells to another, in B2C a business sells to consumers at its own prices, and in C2C consumers trade with each other, as on auction sites. None of these has the consumer fixing the price for a business to accept.

Answer: C

The one that is not an e-procurement portal is MP Online.

MP Online is the Madhya Pradesh government's citizen-services portal, run through a network of kiosks. People use it to fill in examination and admission forms, pay bills and apply for certificates; it is not a platform for government purchasing.

The others are procurement platforms. MP Tenders is the state's e-procurement portal for government tenders, GeM (Government e-Marketplace) is the national online marketplace for government purchases of goods and services, and MP LUN (Madhya Pradesh Laghu Udyog Nigam) is the state agency through which departments procure goods.

Answer: A

The connection that uses telephone lines is DSL.

A Digital Subscriber Line carries data over the ordinary copper telephone line, using frequencies above those used for voice, so the same line can carry a phone call and broadband data at once. ADSL, the asymmetric form, gives faster download than upload speeds.

Cable internet uses the coaxial cable network of cable television, fibre optics uses glass fibres that carry light, and satellite internet uses radio links to satellites; none of these runs over telephone lines.

Answer: A

An advantage of e-commerce is the ability to operate 24/7.

An online store is open at all hours: customers can browse and order whenever they like, and the business can take orders without staff on duty. E-commerce also offers wide geographical reach, lower costs of running a shop, and the ability to personalise recommendations using customers' data.

The other options describe the opposite of e-commerce's strengths: its reach is wide, not limited; it makes personalisation easier, not impossible; and it usually lowers operating costs compared with physical stores.
