Computer Fundamentals and System Concepts Questions

Multiple choice computer
  1. hard drive

  2. keyboard

  3. monitor

  4. system board

  5. RAM

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

IBM BIOS POST error codes use specific number ranges to indicate hardware failures. The 3xx range specifically indicates keyboard-related errors during the Power-On Self-Test. Other ranges include 1xx for system board, 2xx for RAM, and 4xx for video/monitor issues, making 3xx the correct answer for keyboard problems.

C Correct answer
Explanation

CGA (Color Graphics Adapter) supports a maximum of 16 colors simultaneously. While it had multiple graphics modes, the highest color mode was 4-bit color depth (2^4 = 16 colors). This was a significant limitation compared to later standards like VGA (256 colors) and SVGA.

Multiple choice computer
  1. It lacked a level 2 cache, so performance was slower than expected.

  2. It wasn't compatible with Windows 98.

  3. There was a bug in its mathematical calculations.

  4. It sounds like a vegetable you'd leave on your plate.

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The first Celeron processor (Covington core) lacked Level 2 cache memory, which severely impacted its performance. Without L2 cache, the CPU frequently waited for data from slower main memory, making it perform worse than expected despite its clock speed. Later Celeron models (Mendocino core) added L2 cache and improved significantly.

Multiple choice computer
  1. The Japanese word for "pirated software."

  2. Powerful editing software for digital photographs.

  3. Code-name for a processor scheduled for release by Intel in 1999.

  4. A computer-controlled cat litter cleaner. CW

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Katmai was the internal code name for Intel's Pentium III processor, released in 1999. Intel historically used code names for processors during development, and Katmai introduced the SSE instruction set for improved multimedia performance.

Multiple choice networking
  1. netstat

  2. Performance Monitor

  3. Network Monitor

  4. Optimize

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Performance Monitor (PerfMon) is the standard administrative tool in Windows NT and later versions used to monitor system resources like CPU usage, memory, and disk activity. netstat is for network statistics, and Network Monitor is for packet sniffing.

Multiple choice web-design
  1. What You Saw Is What You Got

  2. What You See is What You Get

  3. What You Seen is What You Gotten

  4. What You Sew is What You Get

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

WYSIWYG stands for 'What You See Is What You Get' - it describes systems where content displayed during editing appears exactly as the final output. This is commonly used in text editors, web design tools, and document processors. The other options either use incorrect grammar ('Seen', 'Sew') or change the wording ('Saw' instead of 'See').

Multiple choice server windows-2003
  1. Applications tab

  2. Processes tab

  3. Performance tab

  4. Networking tab

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Applications tab in Task Manager displays currently running applications and has a 'New Task' button (or you can press File > New Task) that allows you to start programs that are not currently running. The Processes tab shows all processes but is not designed for launching applications. Performance and Networking tabs display system statistics only.

Multiple choice c sharp
  1. Spoke

  2. Hub

  3. Satellite

  4. Sputnik

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

To answer this question, we need knowledge about the terminology used in computer programming or software development.

The correct answer is: C. Satellite

Explanation:

A satellite assembly is an assembly that contains localized resources such as strings, images, and other types of data specific to a particular culture or language. These assemblies are used in internationalization and localization of software applications to provide different language versions or regional variations of the application.

Option A: Spoke is not the correct answer. In the context of computer programming or software development, "spoke" is not a term used to describe an assembly that contains localized resources.

Option B: Hub is not the correct answer. In the context of computer programming or software development, "hub" is not a term used to describe an assembly that contains localized resources.

Option D: Sputnik is not the correct answer. In the context of computer programming or software development, "sputnik" is not a term used to describe an assembly that contains localized resources.

Therefore, the correct answer is C. Satellite.

  3. Program

  4. None of the Above

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

An autoresponder is a computer program that automatically sends pre-written responses to incoming emails. It's commonly used for out-of-office messages, marketing campaigns, and customer service to acknowledge receipt of emails. 'Command' and 'Software' are too generic - autoresponder specifically refers to the automated program functionality.
