Internet And Web Technology — Part 1 MCQs with Explanations

The first publicly available internet service in India was launched by state-owned Videsh Sanchar Nigam Limited (VSNL) on 15 August 1995. At the time, VSNL had a monopoly over international communications in the country and private enterprise was not permitted in the sector.

URL stands for Uniform Resource Locator. It is the address of the web page that is displayed on the internet. A URL is used to specify the location of a resource on the web, allowing browsers to retrieve and display the web page. Option A is incorrect because a web browser is a tool used to access web pages, not the address. Option B is incorrect as search engines help in finding web pages, but they are not URLs. Option D is incorrect since a URL is not a computer software but an address format.

The correct answer is A: Hyper Text Transfer Protocol Secure Let's break down what HTTPS means so it's easy to understand: * Hyper Text Transfer Protocol (HTTP) : This is the basic way your computer talks to a web server to get information (like web pages, images, etc.). Think of it as the language they use to communicate. * Secure (S) : The "S" in HTTPS means that the connection between your computer and the website is encrypted . Encryption is like scrambling the information so that if someone tries to eavesdrop, they can't read what's being sent back and forth. So, putting it all together: * HTTPS is the secure version of HTTP. It makes sure that your information (like passwords, credit card details, etc.) is kept safe and private when you're using a website. The other options are incorrect because: * Translation is not part of the protocol. It's about transferring data. * Service is too vague. The "S" specifically refers to security through encryption. Always look for the padlock icon in your browser's address bar and "HTTPS" at the beginning of the website address. This means the website is using a secure connection !

The correct answer is Option B: HTTPS . Let's break down why: Option A: HTTP (Hypertext Transfer Protocol) : This is the basic protocol for transferring data on the web, but it doesn't offer any encryption or security. Think of it like sending a postcard – anyone can read it. Option B: HTTPS (Hypertext Transfer Protocol Secure) : This is the secure version of HTTP. The "S" stands for "Secure". It uses encryption to protect the data being transmitted between your browser and the website. This means that if someone tries to intercept the data, they won't be able to read it because it's scrambled. Think of it like sending a letter in a sealed envelope – only the intended recipient can open and read it. Therefore, it's used to secure websites. Option C: Bookmark : This is simply a saved link to a website so you can easily access it later. It has nothing to do with website security. Option D: History : This is a record of the websites you've visited. It also doesn't provide any security for websites. So, HTTPS is the key to a secure website connection because it encrypts the data!

The correct answer is B: Rootkits. Let's break down why: A: Antiware - This isn't a real term in computer security. It sounds like it might be the opposite of malware, but it's not a standard term. B: Rootkits - This is the correct answer. A rootkit is a set of software tools designed to conceal its presence and the presence of other malware on a computer system. Crucially, it allows an attacker to gain "root" or administrative access , meaning they can control the computer as if they were the owner. C: Backdoors - A backdoor is a secret way to access a system, bypassing normal security measures. While malware can *use* backdoors, backdoors themselves aren't necessarily *designed* to gain root access; they simply provide a shortcut. Rootkits are more directly aimed at gaining full control. D: Malware - Malware is a broad term for any malicious software, including viruses, worms, Trojans, etc. While rootkits *are* a type of malware, the question specifically asks about programs designed to gain root/administrative access. Rootkits are *specifically* designed for this purpose, whereas other types of malware might have different goals. Therefore, Rootkits are the best answer because they are specifically designed to gain root or administrative access.

E-mail is an electronic method of sending messages and files through the internet. An e-mail contains different fields such as To , CC , BCC , Subject , and attachments. Let us examine each option carefully: Option A: An e-mail cannot contain both pdf and zip file as an attachment This statement is false because an e-mail can contain multiple types of attachments at the same time, including PDF , ZIP , images, documents, videos, and more. For example, a user can attach both a report.pdf file and a documents.zip file in the same e-mail. Option B: CC field can be empty in an email This statement is true . The CC (Carbon Copy) field is optional in an e-mail. It is used when the sender wants to send a copy of the message to additional recipients for information purposes. An e-mail can still be sent even if the CC field is left blank. Option C: E-mail cannot have more than 5 attachments This statement is false because there is no fixed rule limiting e-mails to only 5 attachments. Most e-mail services allow many attachments as long as the total file size remains within the allowed limit. Option D: To field in email cannot be blank This statement is generally considered false in such objective questions because an e-mail can also be sent using only the CC or BCC fields in many e-mail systems. Therefore, the clearly correct statement among the given options is: Option B: CC field can be empty in an email .

Option A: SNMP is used for managing network devices, not for getting emails. Option B: ICMP helps computers communicate about network problems (like "ping"). It's not related to email. Option C: POP3 is the answer! This is a protocol that lets your computer download emails from the server to your computer. Option D: DHCP is used for giving computers their network addresses (IP addresses). It's not involved in getting emails. Therefore, the correct answer is C: POP3.

The Internet is a large network of networks that connects millions of private, public, academic, business, and government networks worldwide. Key Points: The Internet allows the exchange of information and communication across the globe using standardized protocols such as TCP/IP. It is not limited to internal communication for businesses or specific government systems but is a universal network accessible to anyone with proper access. It includes various services such as email, the World Wide Web (WWW), file sharing, and more. Therefore: The Internet is best described as a large network of networks .

Imagine a door with a lock. You need a key (your password ) and to say who you are (your login name ) to get in. Similarly, when you log in to a computer system or website, your login name and password are checked to make sure you are who you say you are. This process verifies your identity and grants you access to the system's resources. Option A is partially correct but not the complete picture. It's about proving you are who you claim to be, but it's also about enabling access. Option B is about making sure you're still you, which usually happens after you’re already logged in. Option D is too general. The main purpose is to verify you and provide access. Therefore, the best answer is Option C because it directly addresses the purpose: granting access once your identity is verified.

The correct answer is Option D: All of the above . Here's why: Spiders or Web crawlers: These are like tiny robots that explore the internet. They follow links from one webpage to another, collecting information about websites. So, they are essential for discovering content for a search engine. Indexing software: Once the spiders have collected information, the indexing software organizes it. It creates a massive index, kind of like the index at the back of a book, allowing the search engine to quickly find relevant web pages when you search for something. Therefore, indexing is crucial for efficient searching. Search algorithm: This is the brain of the search engine. It's a set of rules and instructions that determines which search results are the most relevant to your query. It looks at the words you typed, the content of the webpages, and many other factors to decide what to show you. A good search algorithm is fundamental for providing useful results. Because all three components (spiders, indexing software, and search algorithms) work together to make a search engine function, "All of the above" is the correct answer.

AltaVista was a Web search engine established in 1995. It became one of the most-used early search engines, but lost ground to Google and was purchased by Yahoo! in 2003, which retained the brand, but based all AltaVista searches on its own search engine.

The correct answer is Option B: 1960s. Let's break down why: The Internet as we know it didn't just appear overnight. It evolved from earlier research and networking projects. Option A (1950s): While there was early computing research in the 1950s, it wasn't directly related to the Internet's development. Option B (1960s): The Internet's conceptual foundation and key technologies started taking shape in the 1960s. Specifically: The ARPANET (Advanced Research Projects Agency Network) , often considered the Internet's precursor , was established in 1969 . This used packet switching , a key technology for the Internet. Option C (1970s): The 1970s saw important protocol developments like TCP/IP , which are crucial for how the Internet works. But the *initial* development began earlier. Option D (1980s): The 1980s were a period of growth and standardization for the Internet, but not its origin. Option E (1990s): The 1990s mark the rise of the World Wide Web and the widespread *adoption* of the Internet by the public. Again, the fundamental development came *before* this. Therefore, the 1960s are considered the decade when the initial development and fundamental concepts of the Internet were established.

The correct answer is E-commerce. Let's break down why: E-commerce stands for Electronic Commerce . It specifically refers to the buying and selling of goods and services online . Think of it as a virtual marketplace where you can buy anything from clothes to electronics to groceries. Now let's look at the other options: E-selling n buying: While close, it's not the formal or widely accepted term. E-trading: This term usually refers to online stock trading or financial instrument trading, not general goods. E-finance: This relates to managing finances online , like banking or investments. E-salesmanship: This implies selling skills applied online , but not the whole process of trading goods. Therefore, E-commerce is the most accurate and comprehensive term for trading goods over the internet.
