Computer Fundamentals and System Concepts

A retrovirus is specifically designed to detect, disable, or delete antivirus software and other security programs on a system. By attacking the antivirus software first, it can evade detection and remain undetected while infecting the system.

By definition, an android is a robot designed to resemble a human in appearance and behavior. The word comes from Greek 'andros' meaning man/human. Options A, B, and C describe general robot capabilities, not the specific characteristic that makes a robot an android.

A retrovirus is specifically designed to attack antivirus programs by infecting and disabling them. Unlike worms or trojans, retroviruses target security software to avoid detection. This is a specialized malware category.

The Pentium FDIV bug (1994) was a floating point unit (FPU) flaw causing division errors. It specifically affected the FPU, not cache, socket, or other components. Intel eventually recalled affected chips.

A boot sector virus (also called a system virus in some contexts) infects the boot sector of a disk or master boot record of a hard drive, executing during the boot process before the operating system loads. This allows it to gain control early in the startup sequence. Trojan horses, file viruses, and macro viruses target different infection vectors and are not boot-specific.

Macromedia, the software company behind Flash, Dreamweaver, and Director (later acquired by Adobe in 2005), used "What the web can be" as their tagline during the late 1990s and early 2000s, reflecting their focus on web development and multimedia tools.

Firmware is software that is permanently stored in hardware (typically ROM chips). It provides the essential instructions for how the device's hardware communicates with other hardware and software, making it a true combination of both hardware and software components.

Ada Byron (Ada Lovelace) is featured on the watermark of Microsoft's Certificate of Authenticity. She was a mathematician and writer known for her work on Charles Babbage's Analytical Engine and is often regarded as the first computer programmer. Melinda Gates is Bill Gates' wife, while Ella Fischer and Anna Jones are not historical figures associated with computing.

Creeper was indeed the first computer virus, detected on ARPANET in the early 1970s. It moved between PDP-10 systems running the TENEX operating system and displayed the message 'I'M THE CREEPER. CATCH ME IF YOU CAN.' The program was created by Bob Thomas as an experiment in self-replicating code.

Douglas Engelbart invented the computer mouse at Stanford Research Institute in the 1960s. It revolutionized human-computer interaction by providing an intuitive pointing device. Webcam, graphics card, and sound card are important computer components but were invented by others at different times.

VAC (Valve Anti Cheat) is Valve's official anti-cheat system implemented in Counter-Strike and other Steam games. It automatically detects and bans players using known cheats and hacks. The other options - VCC, VNC, and AntiHack - are not the names of Valve's anti-cheat system.

The Internet is the quintessential example of connectivity - a global network connecting billions of devices, systems, and people worldwide. Connectivity refers to the capability to link and exchange data between different computing systems, which is exactly what the Internet enables. Floppy disks and power cards are storage/external devices, while 'data' itself is not a form of connectivity.
