A GPU (Graphics Processing Unit) is a specialized electronic circuit designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device. One of the primary roles of the GPU in gaming is to enhance in-game physics, which refers to the laws and rules that govern the behavior and interaction of objects within a game. GPUs are designed to handle complex calculations quickly and efficiently, making them ideal for handling the physics calculations required in modern video games. By offloading these calculations to the GPU, game developers can create more realistic and immersive games without overloading the CPU (Central Processing Unit). References: CompTIA IT Fundamentals (ITF+) Certification Guide, page 23; What is the GPU’s role in enhancing in-game physics and simulations?

A concurrent license is a type of software license that allows a software program to be installed on as many computers as the company wants, but only a limited number of users can use the software at the same time. A concurrent license is based on the number of simultaneous users rather than the number of installations. A concurrent license can help a company save money and resources by sharing the software among multiple users who do not need to use the software all the time. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 211.

802.11b is the wireless standard that supports speeds up to 11Mbps and operates on the 2.4GHz band. 802.11b is one of the earliest versions of the IEEE 802.11 family of standards for wireless local area networks (WLANs). 802.11b uses direct-sequence spread spectrum (DSSS) modulation to transmit data over radio waves. 802.11b has a maximum theoretical data rate of 11Mbps and a typical range of up to 150 feet indoors or 300 feet outdoors. 802.11b operates on the same frequency band as some cordless phones, microwaves, and Bluetooth devices, which may cause interference or signal degradation. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 171.

The Basic Input/Output System (BIOS) is firmware installed on the motherboard used for hardware initialization during the boot-up process and provides runtime services for operating systems and programs. To reset the boot order on a computer, a technician would access the BIOS setup utility. This utility allows the modification of the sequence in which the hardware storage devices are read by the computer during boot-up.References: Understanding BIOS and its role in system boot processes is a fundamental topic in IT, especially covered in CompTIA A+ and IT Fundamentals certifications.

NTFS (New Technology File System) is the filesystem most likely to be chosen when encryption support is required on a Windows PC. NTFS supports various features not available in other file systems like FAT32, such as file-level security, data compression, and encryption. It is the default file system for Windows operating systems and is suitable for modern uses that require enhanced security features, including encryption.

References: NTFS and its capabilities, including support for encryption, are standard topics in IT education materials, such as those provided by CompTIA, especially in discussions related to Windows operating systems and their configurations.

The first thing a user should do when setting up a new wireless access point is to change the default password. Default passwords are well-known and pose a significant security risk. Changing this ensures that unauthorized individuals cannot easily gain access to the access point’s management interface.

A. Change the SSID to a unique name is important but not the first priority.

C. Enable WPA2 encryption is a key step for securing the network, but only after securing the device itself.

D. Enable the highest available wireless standard improves performance but should come after securing the access point.

In a scenario where an executive is sharing slides in a conference room, the most likely application used is presentation software. Presentation software allows users to create slideshows that typically include a variety of elements such as text, images, and videos, which are ideal for delivering information clearly and engagingly during meetings or presentations. Examples include Microsoft PowerPoint, Google Slides, and Apple Keynote.References: This is consistent with common IT knowledge and practices as understood in IT fundamentals and further verified by CompTIA A+ and CompTIA IT Fundamentals documentation.

 UNIX and Linux are the examples of operating systems that do not require extensions on files to execute a program. UNIX and Linux are operating systems that are based on the same kernel and share many features and commands. UNIX and Linux do not rely on file extensions to determine the file type or function. Instead, they use file permissions and attributes to indicate whether a file is executable or not. File extensions are optional and mainly used for human readability or compatibility with other systems. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 86.

 A WLAN card would be the best choice for a user who wants to use a laptop outside the house and still remain connected to the Internet. A WLAN card stands for wireless local area network card, which is a device that allows a laptop to connect to a wireless network using radio waves. A WLAN card can enable a laptop to access the Internet through public or private wireless hotspots, such as cafes, libraries, airports, or homes. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 170.

Privacy expectations on a company intranet should be governed by the system usage agreements or acceptable use policies (AUPs) that employees are required to sign. These agreements outline the limits and expectations regarding employee privacy, use of the company's IT systems, and monitoring practices. Companies often make it clear that any data or activity on the intranet may be monitored, limiting personal privacy expectations in the workplace.

A. Precedents may influence policies, but privacy expectations are not based on them.

B. HR policy is more focused on employee relations and may reference IT policies, but it is not the primary document for setting IT privacy rules.

C. Word of mouth is not a reliable or enforceable method for establishing privacy expectations.
