1 KB (kilobyte) equals approximately 8,000 bits. This calculation is based on the understanding that 1 byte consists of 8 bits, and a kilobyte is made up of about 1,000 bytes. Therefore, multiplying these values together gives us 8,000 bits for 1 kilobyte.
References:The basic units of digital information and their conversions, including bytes and bits, are frequently covered in CompTIA IT Fundamentals study materials, particularly in sections dealing with data storage and digital concepts.
Question 61
Which of the following programming concepts uses properties and attributes?
Objects are a programming concept that represent entities or concepts in the real world. Objects have properties and attributes that describe their characteristics and behavior. For example, a car object may have properties such as color, model, speed, and fuel, and attributes such as engine, wheels, doors, and seats. Objects can also have methods, which are actions that the object can perform or that can be performed on the object. For example, a car object may have methods such as start, stop, accelerate, and brake. Objects are used to organize data and functionality in a modular and reusable way.
Question 62
Which of the following is an example of PI I? (Select two).
Personally Identifiable Information (PII) refers to data that can be used to identify, contact, or locate a single person, or to identify an individual in context. A full name and date of birth are classic examples of PII because they can directly identify a person. Other options listed may relate to a person's life but do not specifically and directly identify an individual in most contexts.References: The definition and examples of PII are part of data privacy topics covered under the CompTIA IT Fundamentals, which discusses security measures and identification data types.

Question 63
Which of the following can transmit graphics but not sound?
VGA (Video Graphics Array) is an analog interface used between a computer and monitor or projector that transmits video signals. Unlike HDMI and DisplayPort, VGA does not support the transmission of audio signals. It only handles graphics, thus it is often used in situations where only video output is needed without audio.
References: The functionalities of different video connectors like VGA, HDMI, and DisplayPort are often covered in CompTIA IT Fundamentals study materials, particularly in sections related to computer hardware and peripherals.
