Internet and Web

To solve this question, the user needs to know about HTTP compression and its history.

HTTP compression is a technique that reduces the amount of data transmitted between a server and a client by compressing the data before it is sent over the network. This can improve the performance of web pages and reduce the amount of bandwidth required to load them.

Now, let's go through each option:

A. 1996: This option is incorrect. HTTP compression was not introduced until later, so web browsers developed before 1996 would not support it.

B. 1997: This option is also incorrect. While some early implementations of HTTP compression were developed around this time, it was not widely adopted until later.

C. 1998: This option is correct. The first version of the HTTP compression protocol, called "mod_gzip," was introduced in 1998. Web browsers developed after this time should support HTTP compression.

D. 1999: This option is incorrect. While HTTP compression was becoming more widely used around this time, it had already been introduced the year before.

E. 2000: This option is incorrect. By 2000, HTTP compression was well established and widely supported by web browsers.

Therefore, the answer is: C. 1998

Browser information is accessed through the navigator object, not a 'browser' object. The appName property specifically returns the browser name. Option B correctly uses navigator.appName. Option A uses a non-existent 'browser' object. Option C invents a 'client.navName' property.

Novell NetWare's directory service is called NDS (Novell Directory Service), later renamed eDirectory. Active Directory is Microsoft's equivalent, DNS is the Domain Name System, and NWLink is NetWare's IPX/SPX protocol implementation. NDS was NetWare's hierarchical directory database for network resource management.

HTTP (HyperText Transfer Protocol) is indeed the primary protocol used for viewing web pages. It defines how messages are formatted and transmitted between web browsers and web servers. While HTTPS (secure HTTP) is now standard for security, the base protocol remains HTTP.

The Internet Society (ISOC) is the ultimate organizational authority for the internet, providing oversight and funding for IETF activities. IETF develops technical standards under ISOC. IAB oversees IETF's technical work. ISOC owns the IETF trademark and appoints IAB members.

PHP originally stood for 'Personal Home Page' but was later renamed to be a recursive acronym 'PHP: Hypertext Preprocessor'. The recursive name (where the P stands for PHP) is the current official name and the correct answer. This renaming reflected PHP's evolution beyond personal home pages to a general-purpose web scripting language.

PageRank is Google's proprietary algorithm that assesses web page importance by analyzing both the quantity and quality of inbound links. It operates on the principle that valuable pages receive more links from other reputable websites. Option A describes general search relevancy, not PageRank specifically. Options C and D incorrectly attribute PageRank to Yahoo! and Alexa respectively, when it is exclusively Google's technology.

The link: operator in search engines shows backlinks that are specifically indexed by that search engine, not all backlinks across the entire web. This is a crucial distinction because search engines don't index every page on the internet. Option A is incorrect because it suggests the link operator shows all backlinks universally. Option C confuses the link operator with a direct URL lookup, while Option D describes a different SEO tool for analyzing anchor text.

Google bombing involves multiple websites linking to a target page using identical anchor text to manipulate search rankings for that specific keyword phrase. This exploits Google's reliance on anchor text as a ranking signal. Option A describes submission spamming, not Google bombing. Option C refers to keyword stuffing, which is a different manipulation technique. Google bombing specifically targets the collective power of inbound links with matching anchor text.

This statistic highlights that search engines are the primary discovery mechanism for finding new websites, overshadowing other channels like advertising, email, or word-of-mouth. The 81% figure underscores the critical importance of SEO for online visibility. While the exact percentage may vary by study and year, the fundamental point stands: search dominates web discovery.

Search engines, particularly Google, place high value on 'backlinks' (other websites linking to yours). This is viewed as a 'vote of confidence' or an indicator of authority, significantly impacting the site's search ranking.

SEO involves both on-page factors (optimized content, keywords, meta tags) and off-page factors (quality inbound links from relevant sites). Option A describes paid search advertising, not organic SEO. Option B is incomplete - meta tags alone are insufficient. Option D describes PPC (pay-per-click) advertising strategies. Option C correctly captures that effective SEO requires combining quality content with authoritative backlinks.

The search engine market is highly concentrated, with Google, Bing, Yahoo, and a few others accounting for over 90% of all search traffic globally. This means optimizing for these few engines is more critical than trying to please hundreds of minor engines. Option A (1000+) and B (100+) overestimate the market fragmentation. Option C (10+) is closer but still too high. Option D (2) is too narrow.

If your site has quality inbound links from other websites, Google's crawlers will discover and index it naturally through those links. Manual submission is unnecessary once you have good backlinks. Submitting repeatedly (daily, weekly, or monthly) provides no benefit and could potentially be seen as spam. Google prefers natural discovery through links.
