 Integer is a data type that can store whole numbers, such as 1, 0, or -2. Integer would be the best data type to use for creating a variable to hold an age value because age is usually expressed as a whole number of years. Float, double, and string are not data types that would be suitable for creating a variable to hold an age value. Float and double are data types that can store decimal or fractional numbers, such as 3.14, 0.5, or -2.75. String is a data type that can store text or characters, such as “Hello”, “A”, or “123”. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 4: Programming Concepts and Data Structures, page 146.

Processing speed is measured in hertz (Hz), which is the number of cycles per second that a processor can perform. The higher the hertz, the faster the processing speed. There are different units of hertz, such as megahertz (MHz), which is one million hertz, and gigahertz (GHz), which is one billion hertz. Therefore, 3.4MHz is the slowest processing speed among the given options, as it is equivalent to 3.4 million hertz. 2.6GHz is equivalent to 2.6 billion hertz, which is the fastest processing speed among the given options. 5000Kbps and 4Mbps are not units of processing speed, but units of data transfer rate, which measure how much data can be transmitted over a network in a given time. Kbps stands for kilobits per second, and Mbps stands for megabits per second. One megabit is equal to 1000 kilobits, so 4Mbps is equivalent to 4000Kbps. References: The Official CompTIA IT Fundamentals (ITF+) Student Guide (Exam FC0-U61), Chapter 1: IT Fundamentals

A logical schema in database design is a visual diagram that represents the framework or structure of the database, without getting into the details of physical storage. It includes tables, views, and the relationships between them, and is used to conceptualize and plan the structure of the database at a high level. This makes it an essential tool for a database administrator when planning a new relational database, as it helps in understanding how data will be stored, linked, and accessed.

References: The concept of logical schemas is discussed in IT and database design textbooks and CompTIA IT Fundamentals resources as part of learning about effective database management and design.

 Interpreted is the type of language that a web developer would most likely use to create a website. Interpreted languages are languages that do not need to be compiled before execution. Instead, they are translated into machine code by an interpreter program at run time. Interpreted languages are often used for web development because they are portable, flexible, and easy to modify. Examples of interpreted languages include HTML, CSS, JavaScript, PHP, and Python. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 132-133. edge browser The user has the page open in a Microsoft Edge browser window whose metadata is:
