Computer Hardware and Software Fundamentals

A database management system (DBMS) is a software system used to create, maintain and provide controlled access to a database.

Yes, it is the shortcut to prevent any CD from auto start.

This software enables you to create a duplicate copy of a CD. This software first copies the image from the original CD. Then, it burns the image on the blank CD.

Application software aims at solving some user defined problems like accounting, managing, reservations, billing, etc.

System software aims at making the computer a user friendly machine. A computer is a machine that knows nothing of itself. It requires instructions for each and everything it performs and the instructions provided to the software control internal computer operations, like reading data from input devices, checking system components, etc. Hence, system software is the software which aims at making the computer a user friendly machine. 

Loader is the program that helps to load other programs from input systems. So, loader is the program which helps in loading the executable files from secondary storage to main memory.

An operating system acts as an interpreter between software and hardware.

A browser is stored in a computer's hard disk.

The location where input/output devices are connected to the computer is known as port.

Correct option is (4). 

A trackball is essentially an upside-down mouse - you rotate a ball with your thumb or fingers to control cursor movement, just as a joystick is manipulated by hand to control movement on screen. Both trackballs and joysticks are pointing devices that involve direct manual manipulation to control position, whereas a mouse is moved across a surface and a light pen is dragged across the screen. Trackballs and joysticks share the same fundamental operational principle.

Option (4) is the correct answer.

A hard disk drive is a storage device that holds all types of software permanently, including operating systems, device drivers, applications, and user programs. Monitor (option A) is an output device that only displays information. ROM (option B) contains firmware but is not rewritable for storing applications. Video adapter (option C) processes graphics output but doesn't store software. Only the hard disk has the capacity and rewritability to hold all these programs.

A CRT (Cathode Ray Tube) monitor consists of several key components: the phosphor screen that glows when struck by electrons, the shadow mask that ensures electrons hit the correct phosphor dots, and the electron gun that emits the electron beam. Gas plasma is an entirely different display technology used in flat-panel displays, not in CRT monitors. This is a knowledge-based question about CRT monitor architecture.
