Computer Technology & Internet History

CP/M (Control Program/Microcomputers), created by Gary Kildall in 1974, was the first operating system to gain widespread use on personal computers, particularly on early machines running on Intel 8080 and Zilog Z80 processors. It served as the foundation for many early PC operating systems and influenced the design of MS-DOS.

In computing, a 'nibble' (also spelled 'nybble') is indeed half a byte, consisting of 4 bits. The term is a play on 'byte' and has been used in computer science since the 1950s. It's a standard unit of digital information that can represent 16 different values (0-15).

A mickey is indeed the unit of measurement for mouse movement in computing. It represents the smallest increment of movement that a mouse can detect and report to the computer. Option D is incorrect as it refers to sensitivity (which is measured differently), while option A describes a mouse pointer and C describes a wireless mouse, not the unit itself.

The floppy disk was indeed developed by IBM in the late 1960s, specifically by an IBM team led by David Noble. While the question asks 'who' (implying a person), all options are companies, and among these choices, IBM is the correct answer as they were the organization that invented and commercialized the floppy disk.

Ray Tomlinson is widely credited with inventing email in 1971. He implemented the first email system on the ARPANET and introduced the use of the '@' symbol to separate user names from machine names. The other options (chat rooms, P2P networks, online games) were developed later and by different people.

Deep Blue was the IBM supercomputer famous for playing chess against world champion Garry Kasparov in 1997. However, the question's phrasing 'only use' is misleading - while Deep Blue is best known for chess, supercomputers are general-purpose machines. The question seems to be testing knowledge of Deep Blue's most famous application rather than its actual technical capabilities.

Intel manufactured the world's first commercial microprocessor, the Intel 4004, in 1971. It was a 4-bit processor originally designed for a Japanese calculator company. Celeron is Intel's own budget processor line (not a manufacturer), Seagate makes storage products, and IBM entered the microprocessor market later.

The Turing Test, proposed by Alan Turing in 1950, measures a machine's ability to exhibit intelligent behavior equivalent to a human. In the test, a human judge engages in natural language conversations with both a human and a machine, without knowing which is which. If the judge cannot reliably distinguish between them, the machine is said to have passed the test.

A modem (modulator-demodulator) is a device that modulates and demodulates analog signals to encode and decode digital data for transmission. It converts digital computer signals into analog signals for transmission over telephone lines, and then converts the analog signals back into digital form at the receiving end. This technology enabled early internet connectivity through phone lines.

The term 'Web 2.0' was coined in 2004 by Dale Dougherty of O'Reilly Media during a conference brainstorming session. While Tim O'Reilly popularized and elaborated the concept, Dougherty first articulated it to describe the emerging read-write, participatory web era.

According to Tim O'Reilly, Web 2.0's core philosophy is democratization - empowering users to create, share, and collaborate rather than just consume content. This shift enabled platforms like blogs, wikis, and social networks where users actively participate rather than passively browse static pages.

Web 1.0 (1990s-early 2000s) was characterized by static, read-only websites where content was published by owners and consumed by users without interaction. These brochure-style sites featured HTML pages with minimal user engagement - no comments, no social sharing, no user-generated content.

An official online encyclopedia represents a Web 1.0 site because it's a static, read-only resource where experts publish content for users to consume without interaction. Unlike Web 2.0 sites with user comments, reviews, or contributions, Web 1.0 encyclopedias were one-way information sources without social features.

HTTP (Hypertext Transfer Protocol) is considered the backbone of the World Wide Web because it's the foundation protocol that enables communication between web servers and browsers. Every web page request, image load, and data transfer relies on HTTP to transport HTML, CSS, JavaScript, and other resources across the internet.

Email uses protocols like SMTP (Simple Mail Transfer Protocol), POP3, or IMAP to send and receive messages independently of HTTP. While web-based email services (Gmail, Outlook) use HTTP in their browser interfaces, the underlying email system operates through dedicated mail servers and protocols that don't require web browsers or HTTP.

In client-server networking, a client is a computer that requests resources or files from a server. A host is any device on the network, a router directs traffic, and a web server specifically serves web content.

Plug-ins are programs that enable web browsers to play multimedia files and perform additional tasks beyond basic HTML rendering. They extend browser functionality to handle audio, video, and interactive content.

The Internet began with ARPANET (Advanced Research Projects Agency Network) in 1969, funded by the US Department of Defense. USENET came later (1980), Ethernet was developed at Xerox PARC (1973), and Intranet is a private internet.

Displacement is a vector quantity that includes both magnitude AND direction. '5 km north' specifies both the distance (5 km) and the direction (north), making it a measure of displacement. Options A and D are distances (scalars), while C is speed.
