NFC (Near Field Communication) is a wireless technology that allows devices to communicate and exchange data within a short range, typically a few centimeters. NFC is commonly used for tap to pay transactions, where a customer can use a contactless card or a smart device (such as a smartphone or a smartwatch) to make payments by tapping or hovering over a compatible terminal. NFC is different from other wireless technologies, such as Wi-Fi, IR (Infrared), and Bluetooth, because it does not require pairing, authentication, or network access to work. NFC is also faster, more secure, and more convenient than other payment methods, such as inserting or swiping a card. References: CompTIA IT Fundamentals (ITF+) Certification Guide, page 25; What is Tap to Pay and How Does It Work?

The software type that the user should select to prepare handouts for a presentation that are easy to format and printer friendly is word processing. Word processing is a type of software that allows users to create, edit, format, and print text documents, such as letters, reports, resumes, etc. Word processing software provides features such as fonts, styles, margins, alignment, bullets, numbering, tables, images, etc., that enable users to customize the appearance and layout of their documents. Word processing software also provides features such as spell check, grammar check, word count, etc., that enable users to improve the quality and accuracy of their documents. Word processing software can also support various file formats and printing options that enable users to save and print their documents easily and conveniently. Examples of word processing software include Microsoft Word, Google Docs, LibreOffice Writer, etc. Spreadsheet is not the software type that the user should select to prepare handouts for a presentation that are easy to format and printer friendly, but rather a type of software that allows users to create, edit, format, and print numerical data in rows and columns, such as budgets, invoices, charts, etc. Spreadsheet software provides features such as formulas, functions, graphs, pivot tables, etc., that enable users to perform calculations, analysis, or visualization on their data. Spreadsheet software can also support various file formats and printing options that enable users to save and print their data easily and conveniently. Examples of spreadsheet software include Microsoft Excel, Google Sheets, LibreOffice Calc, etc. Text editor is not the software type that the user should select to prepare handouts for a presentation that are easy to format and printer friendly, but rather a type of software that allows users to create, edit, or view plain text files, such as code, scripts, notes, etc. Text editor software provides features such as syntax highlighting, search and replace, indentation, etc., that enable users to manipulate text easily and efficiently. Text editor software does not provide features such as fonts, styles, images, etc., that enable users to customize the appearance or layout of their documents. Text editor software can also support various file formats but not printing options that enable users to save but not print their files easily and conveniently. Examples of text editor software include Notepad++, Sublime Text, Vim, etc.

 One-tier architecture is a type of architecture that uses only one layer or tier for an application or system. In one-tier architecture, the application logic, data, and user interface are all contained within the same layer or tier. One-tier architecture would be the best description of a technology that allows an application to run on a workstation without requiring any other components or layers. Two-tier, three-tier, and n-tier architectures are types of architectures that use more than one layer or tier for an application or system. In two-tier architecture, the application logic and data are separated into two layers or tiers. In three-tier architecture, the application logic, data, and user interface are separated into three layers or tiers. In n-tier architecture, the application logic, data, and user interface are separated into multiple layers or tiers. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 5: Database Fundamentals, page 198.

 A hypervisor is a software program that allows multiple operating systems (OS) to run on the same physical hardware as virtual machines (VMs). A hypervisor can be classified into two types: Type 1 and Type 2. A Type 1 hypervisor interacts directly with the hardware and does not need an underlying OS to function. A Type 1 hypervisor is also known as a bare-metal hypervisor or a native hypervisor. A Type 1 hypervisor can manage storage, network, and VMs more efficiently and securely than a Type 2 hypervisor89. References := CompTIA IT Fundamentals (ITF+) Study Guide, 2nd Edition, Chapter 3: IT Infrastructure3; What is Hypervisor? - Definition from Techopedia10

 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.

In the given pseudocode, the message "Counting" is printed in a loop while X is less than 12. The variable X starts incrementing by 1 each time through the loop. If X starts at 0, the loop will run and display the message 7 times before X reaches 7.

The loop starts with X = 0.

For X values from 0 to 6, the message is printed, making a total of 7 times before X becomes 7 and the loop halts.

DSL (Digital Subscriber Line) is the best solution when telephone lines are available in a remote area but other network infrastructures, like cable or fiber, are limited. DSL uses existing telephone lines to provide internet access and is often a cost-effective solution in areas with limited connectivity options.

A. Cable requires coaxial infrastructure, which may not be available.

B. Fiber optic provides high-speed connectivity but requires specialized infrastructure.

C. Wireless network may be an option, but DSL is a better fit given the availability of telephone lines.

Customer date of birth is an example of information that a company would ask employees to handle in a sensitive manner. Sensitive information is any information that can identify or relate to a specific person, such as name, address, phone number, email, social security number, date of birth, etc. Sensitive information can also include financial, medical, legal, or personal records of a person. Sensitive information should be handled with care and confidentiality by employees to protect the privacy and security of the customers and the company. Employees should follow the company’s policies and procedures for handling sensitive information, such as encrypting, locking, shredding, or disposing of it properly. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 205.

 A query language is a type of programming language that is used to manipulate and retrieve data from databases. A query language allows users to specify what data they want to access, filter, sort, join, or perform calculations on, without having to know how the data is stored or organized. A query language usually consists of keywords, operators, expressions, and clauses that form statements or commands. One of the most common and widely used query languages is SQL (Structured Query Language), which is supported by many relational database management systems (RDBMS).

A query language would most likely include tables and the select command, as these are essential components of working with databases. A table is a collection of data that is organized into rows and columns, where each row represents a record and each column represents a field or an attribute. A table can have a name, a schema (the definition of the columns and their data types), and constraints (the rules that enforce the integrity and validity of the data). For example, in the following SQL code, a table named Customers is created with four columns: CustomerID, Name, Email, and Phone:
