Computer Internet Questions and Answers

Answer: A

URL stands for Uniform Resource Locator.

A URL is the address of a resource on the web, such as https://www.example.com/page.html: it names the protocol, the host and the path to the resource. The term was introduced with the World Wide Web by Tim Berners-Lee.

'Universal Resource Locator' is a common mistake for 'Uniform', and 'Line' in the other two options has nothing to do with the term.

Answer: B

In HTTPS, S means Secure.

HTTPS is the HyperText Transfer Protocol Secure: HTTP carried over an encrypted TLS (formerly SSL) connection, normally on port 443. The encryption protects data such as passwords and card details in transit and lets the browser verify the site's certificate.

Secret, Socket and Software are not what the letter stands for, although the protocol does run over a network socket.

Answer: B

The protocol is HTTPS.

A URL begins with its scheme, the protocol to use, followed by ://. In https://www.google.com the protocol is https; www.google.com is the host name.

'www' is the part of the host name that names the web server, and '.com' is the top-level domain. Since they are not protocols, 'All of these' is wrong too.

Answer: B

The e-mail service provider is Yahoo Mail.

Yahoo Mail is a web-based e-mail service, like Gmail or Outlook.com, that lets users send and receive messages through their accounts.

Linux is an operating system, Photoshop an image-editing program, and MS-Word a word processor; none provides e-mail accounts.

Answer: A

PaaS stands for Platform as a Service.

In cloud computing the three main service models are Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). PaaS provides a ready platform, with operating system, runtime, databases and tools, on which developers build and run applications without managing the underlying servers.

'Program' and 'Product' as a Service are not the standard expansions.

Answer: A

DigiLocker aims to Provide cloud storage for personal documents.

DigiLocker, under the Digital India programme, gives citizens a cloud account where issuing agencies can deposit authentic digital copies of documents such as Aadhaar, driving licences, vehicle registration and mark sheets, which are legally equivalent to the originals.

It is not a banking, shopping or video-conferencing service.

Documents fetched from issuers into DigiLocker can be shown in place of physical copies, for example a driving licence during a traffic check.

Correct answer: ARPANET

ARPANET adopted TCP/IP on 1 January 1983, which is the moment the internet as a protocol family begins. The internet grew out of ARPANET rather than preceding it.
