Computer Fundamentals and System Concepts

The correct answer is C (Activity definition). In an Easytrieve program, the Activity definition section is the only mandatory section. It contains the program logic and processing statements. The Library section and Environment definition are optional - Library is for defining reusable code, and Environment definition is for file and variable declarations. A minimal Easytrieve program can consist solely of activity definitions.

web.xml is the standard deployment descriptor for Java web applications. It contains configuration for servlets, filters, welcome files, and other web application settings. While context.xml exists (in Tomcat), web.xml is the universal deployment descriptor.

Context parameters (defined in web.xml) are application-wide and accessible globally via ServletContext to all servlets and filters in the application. Unlike servlet-specific init parameters, context parameters are shared across the entire application.

Chain-loading is the process where a bootloader (like GRUB) loads and passes control to another bootloader located on a partition's boot record, rather than booting the kernel directly. This is commonly used to dual-boot operating systems like Windows and macOS alongside Linux. The other options are incorrect terminology.

Infrex tool is installed on Siva's PC among the listed team members. This is a factual question about tool deployment/configuration within the team.

Bottom-up integration testing begins with the lowest-level modules and progressively integrates higher-level components. This approach uses test drivers to simulate higher-level modules until they're developed. Starting from terminal modules at the bottom of the hierarchy characterizes the bottom-up approach.

A sandbox is a restricted environment that limits what programs can do, preventing them from accessing certain system resources or performing potentially harmful operations. It's used for security testing and untrusted code execution. Antivirus, worm, and backdoor are types of malware, not security environments.

The CPU (Central Processing Unit) is commonly referred to as a microprocessor. A microprocessor is an integrated circuit that contains all the functions of a central processing unit - it fetches, decodes, and executes instructions. Modern CPUs are indeed microprocessors that contain millions or billions of transistors on a single chip.

Highlighting refers to selecting text by clicking and dragging the mouse cursor over it, which creates a shaded background effect. This is a standard feature in word processors, text editors, and most applications that handle text. Clip art refers to pre-made images, fetch means to retrieve data, and decode means to convert coded information into readable form.

A file server is a computer that stores and manages files accessible to other computers on a network. It provides centralized storage and allows multiple users or systems to share files, printers, and other resources. The other options are incorrect: clip art refers to pre-made images, a motherboard is the main circuit board, and peripherals are external devices connected to the computer.

A computer chip is commonly called a microchip - it's a miniaturized electronic circuit consisting of tiny semiconductor devices on a small piece of semiconductor material. While microprocessors are a type of computer chip, the more general and commonly used term for any integrated circuit chip is microchip. Execute is an action, select is an operation, and microprocessor is a specific type of chip.

To execute means to carry out or perform an instruction. In computing, after a processor fetches and decodes an instruction, it executes it - meaning it performs the actual operation specified by that instruction (such as arithmetic, logic, or data movement). Decode converts coded information, highlight emphasizes text, and select marks an item.

The motherboard is the main printed circuit board in a computer that holds and connects all the essential components. It houses the CPU, memory slots, expansion slots, and provides the electrical connections between all parts of the computer. Everything else plugs into or connects to the motherboard. Decode and highlight are operations, select is an action.

The desktop in computer terminology refers to the main screen area that appears after the computer finishes booting. It displays icons, shortcuts, and provides a workspace where users can organize files and launch applications. The desktop is metaphorical - it's like a physical desk where you work. It is not the physical area around the monitor, the mouse pad, or inside a folder.
