Computer Fundamentals and System Concepts

The correct answer is D 'Switch Board' is the odd one out because it's an electrical fixture, while Monitor, CPU, and Keyboard are all computer components. Switch Board belongs to electrical infrastructure rather than computing equipment.

Double-clicking the 'My Computer' or 'This PC' icon on the desktop opens a window showing all available drives on your system (C:, D:, etc.). This is basic Windows navigation - the computer window displays drives and storage devices, not the desktop contents or control panel directly.

MS Windows is an operating system - the platform that runs other applications. MS Office, Calculator, and WinZip are all application programs that run on top of the operating system. The OS manages hardware and provides services, while applications perform specific tasks for users.

While 'Log off' technically only ends the user session and returns to the login screen, in many enterprise environments or specific OS configurations, logging off can trigger automated shutdown scripts or be part of a power management sequence.

The Windows Calculator can be accessed via the GUI through the Accessories folder in the Start Menu or by typing the executable name 'calc' into the Run dialog box (Win + R). Both methods are standard ways to launch the application.

Silicon is a semiconductor and the primary material used in the fabrication of Integrated Circuits (ICs) because of its stable electrical properties. Lead, chromium, and gold are metals used in various electronic components but not as the base substrate for the chip itself.

The Java System class provides standard input, output, and error streams (in, out, err) and utility methods for system properties, environment variables, and garbage collection. It does NOT provide facilities to load files and libraries or create them - that's the ClassLoader's job.

Teradata uses a Shared Nothing architecture - each node has its own memory and disk. No resources are shared between nodes. This eliminates contention and enables linear scalability. Shared Everything (like SMP) shares memory and disk among processors.

The IBM System/360 (OS/360) was announced in 1964 and was the first family of mainframe computers designed to cover a complete range of applications and standardize mainframe architecture.

The Intel 4004, introduced in 1971, was the first commercially available microprocessor from Intel. The 8080 came later in 1974, and the 8086 in 1978. Option A's 3080 doesn't exist as an Intel processor number and appears to be a distractor. The 4004 was a 4-bit processor that launched the microprocessor revolution.

aspnet_wp.exe is the ASP.NET worker process that executes ASP.NET code. It runs within the application domain and handles page processing, while inetinfo.exe is the IIS admin service and aspnet_isapi.dll is the ISAPI extension filter.

A clean desktop in computer context refers to having no programs or windows open, keeping the workspace clutter-free for better performance and focus. Physical paper items (B) refer to a physical desk, while icon arrangement (C) is about desktop shortcuts, not running programs.

Intel 4004 was the first commercially available microprocessor (CPU on one chip), released in 1971. It was a 4-bit processor. Intel 8085 came much later (1977), and Intel 8086 (1978). Intel 3003 was not a CPU chip.

The kernel is the core component of an operating system that manages system resources and facilitates communication between hardware and software. It handles essential functions like memory management, process scheduling, and device control. Without the kernel, the operating system cannot function.

Cookies are stored on the client side (browser), not the server. They are small text files used for session management and authentication. Cookies are not executable code.
