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.

 A constraint is a rule or a restriction that is applied to a column or a table in a relational database to ensure that only valid values are entered. Constraints help to maintain the integrity, accuracy, and consistency of the data. For example, a constraint can be used to specify that a column must not contain null values, or that a column must contain unique values, or that a column must match a value in another table12. References := CompTIA IT Fundamentals (ITF+) Study Guide, 2nd Edition, Chapter 5: Database Fundamentals3; Constraints in Relational Database Model - Online Tutorials Library

Dumpster diving refers to the act of searching through a company’s trash to find confidential or useful information that has not been properly disposed of. If a company discontinues its secure shredding service and employees fail to adhere to secure disposal protocols, sensitive documents could be easily accessible in the trash, leading to potential security breaches.

References:The risks associated with improper disposal of sensitive information, including dumpster diving, are highlighted in CompTIA IT Fundamentals security modules, which discuss various threats to physical and digital data security.

Using private browsing (or "incognito mode") while accessing sensitive information on a public computer is the best approach to prevent others from seeing what was done during that session. Private browsing does not save a record of browsing history, cookies, or form data, effectively ensuring that subsequent users of the public computer cannot easily retrieve this information from the browsing session.

References: Internet security practices, including the benefits of private browsing, are typically included in CompTIA IT Fundamentals documentation, which covers essential cybersecurity measures for protecting personal information.
