Nocti True Or False Practice Quiz

Explanation
The form factor of a hardware component refers to its physical dimensions, shape, and key characteristics. It helps determine how the component will fit into a system and interact with other components. By understanding the form factor, users can ensure compatibility and proper installation of the component. Therefore, the given statement is true as it correctly states that the form factor describes the size, shape, and major features of a hardware component.

Explanation
Wireless devices can connect to a LAN by using a wireless access point (AP). This is because a wireless access point acts as a bridge between the wireless devices and the wired LAN network. It allows wireless devices to connect to the LAN, access resources, and communicate with other devices on the network. Therefore, the statement "Wireless devices can connect to a LAN by way of a wireless access point (AP)" is true.

Explanation
Software is a set of instructions or programs that tell the hardware what tasks to perform. Without hardware, software cannot function as it needs physical components to execute its instructions. Therefore, it is true that software uses hardware to perform tasks related to input.

Explanation
Printer Control Language (PCL) is indeed a printer language that competes with PostScript. PCL is a page description language used primarily for printing documents on laser printers. It was developed by Hewlett-Packard (HP) and is widely supported by various printer manufacturers. PCL and PostScript are both used to describe the layout and formatting of printed documents, but they have different features and capabilities. While PostScript is more versatile and commonly used in professional printing, PCL is simpler and often used in office environments. Therefore, the statement "True" accurately describes the competition between PCL and PostScript.

Explanation
False. While it is true that server applications require port numbers to listen for incoming connections, not every service running on a computer requires a port number. Some services may not require network communication or may use other means of communication that do not involve port numbers. Therefore, the statement is incorrect.

Explanation
An operating system is a crucial software that manages and controls the various operations of a computer. It acts as an intermediary between the hardware and the user, allowing them to interact with the computer system effectively. The operating system is responsible for managing resources, scheduling tasks, providing a user interface, and ensuring the overall functionality and security of the computer. Without an operating system, a computer would not be able to function properly. Therefore, the statement "An operating system is software that controls a computer" is true.

Explanation
The read/write heads on a hard drive do not touch the surface of the platters. Instead, they float just above the surface on a cushion of air created by the spinning of the platters. This is done to prevent damage to the delicate surface of the platters and to ensure accurate reading and writing of data.

Explanation
A user group is a predefined set of permissions and rights assigned to user accounts. This means that when a user is added to a specific user group, they inherit the permissions and rights associated with that group. By assigning user accounts to user groups, administrators can easily manage and control access to different resources and functionalities within a system or application. Therefore, the given statement is true.

Explanation
This statement is true because the floppy drive is one of the few I/O devices that require hardware control rather than software control. Most other I/O devices, such as keyboards, mice, printers, and monitors, can be controlled by software through device drivers. These drivers allow the software to communicate with the device and perform various operations. However, the floppy drive operates at a lower level and requires direct hardware control to read and write data from the floppy disk.

Explanation
BTX (Balanced Technology Extended) motherboards were designed to be compatible with both ATX and BTX power supplies. Therefore, it is incorrect to say that BTX motherboards cannot use an ATX power supply.
