General Technology Trivia Quiz

In .NET, passing -1 to Thread.Sleep makes the thread sleep indefinitely until it is interrupted or aborted. Other values like zero yield the processor briefly.

A daemon thread runs in the background to perform tasks like garbage collection and does not prevent the JVM or runtime from exiting when all user threads finish.

MAC stands for Media Access Control, which is the unique hardware address assigned to network interfaces (NICs) for communication at the data link layer of the OSI model. It's burned into the network card by manufacturers.

IDE/EIDE (Integrated Drive Electronics/Enhanced IDE) connectors use 40-pin ribbon cables to connect hard drives and optical drives to motherboards. The 40-pin connector became the standard for Parallel ATA (PATA) drives.

Email is not live communication because it doesn't require simultaneous presence of sender and receiver. Chat, Instant Messaging, and IRC (Internet Relay Chat) are synchronous/live forms where participants communicate in real-time.

Perl is a programming language, not a text editor. Vim, Pico, and Vi are all text editors commonly used in Unix/Linux systems. Perl can be used to process text but is a scripting language first.

Tim Berners-Lee invented the World Wide Web in 1989-1990 while working at CERN. He developed HTTP, HTML, and the first web browser/server, creating the foundation of modern web communication. Alan Kay, Jack Kilby, and Robert Noyce made significant contributions to computing but not the web.

802.11a operates in the 5 GHz frequency band and supports a maximum theoretical data rate of 54 Mbps. It was one of the first high-speed wireless standards. Options A, C, and D are incorrect - 100 Mbps is closer to 802.11n/g speeds in ideal conditions, while 24 and 10 Mbps are far below 802.11a's specification.

Amazon is primarily an e-commerce platform, whereas Twitter, Orkut, and Myspace are dedicated social networking sites.

In technology terminology, a hot spot refers to a location that offers public wireless internet access, such as coffee shops, airports, or libraries. The term comes from the 'hot' in 'hotspot' meaning a zone of connectivity. Options A, C, and D describe other computing concepts but are not the standard definition of a technology hot spot.

Private IP addresses for local networks are defined in RFC 1918. 192.168.0.0/16 is one such range, making 192.168.1.100 a valid local network address. The other options are public IP addresses - 74.125.127.100 belongs to Google, 69.72.169.241 is also public, and 209.131.36.100 is a Yahoo address.

Blu-ray discs have the highest capacity among these storage media - standard single-layer discs hold 25 GB, dual-layer hold 50 GB. DVDs hold 4.7-8.5 GB, CDs hold 700 MB, and floppy disks hold only 1.44 MB. The name 'Blu-ray' refers to the blue-violet laser used to read the discs, allowing for much higher data density than the red laser used for DVDs and CDs.

XML stands for eXtensible Markup Language. It was designed to store and transport data in a structured, human-readable format. The 'extensible' means users can define their own tags and document structure, unlike HTML which has predefined tags. Options A, B, and C are incorrect expansions.

Apple's first logo in 1976 featured Sir Isaac Newton sitting under an apple tree, designed by Ronald Wayne. The rainbow-colored apple with a bite came later in 1977. The original Newton logo was complex and inspired by the story of Newton discovering gravity, making it historically significant though it was quickly replaced by the simpler apple design.

FET stands for Field Effect Transistor, a fundamental electronic device that uses an electric field to control the flow of current. Options B, C, and D are incorrect expansions.

CRO stands for Cathode Ray Oscilloscope, a laboratory instrument used to display and analyze voltage waveforms. The cathode ray tube was the traditional display technology for oscilloscopes.

CMOS stands for Complementary Metal-Oxide Semiconductor, a technology used for integrated circuits that employs both n-type and p-type metal-oxide-semiconductor field-effect transistors. The complementary design reduces power consumption.

DAC stands for Digital-to-Analog Converter, which converts discrete digital signals into continuous analog waveforms. Option A incorrectly reverses the direction, and D describes the process rather than the device.

DTMF stands for Dual Tone Multi-Frequency, the signaling system used in telephones where each key press generates two specific tones simultaneously. This enables reliable digit recognition over telephone networks.
