Therefore, the statement "Most LANS use individual computers are called clients" is true, as clients are an essential component of a LAN.

Flash drives are considered secondary storage devices because they are used to store data that is not currently being used by the computer's operating system or applications. Unlike primary storage devices such as RAM, which provide temporary storage for data that is actively being processed, flash drives provide long-term storage for files and data that can be accessed at a later time. Flash drives are portable and can be easily connected to different devices, making them a convenient and popular choice for storing and transferring data.

CDs are not considered primary storage devices. Primary storage devices are typically internal to a computer and include components such as RAM and cache memory. CDs, on the other hand, are considered secondary storage devices as they are used for long-term storage of data and are not directly accessible by the computer's processor.

The statement is true because Linux and Novell are both examples of Network Operating Systems (NOS). A Network Operating System is a software that manages and controls network resources, allowing multiple computers to communicate and share data. Linux is an open-source NOS widely used in server environments, while Novell is a proprietary NOS known for its NetWare operating system. Both Linux and Novell provide the necessary tools and protocols for networking, making them suitable examples of NOS.

The given statement is false because a Macintosh computer does not use the Windows Operating System. Macintosh computers use their own operating system called macOS, which is developed by Apple Inc. Windows Operating System is primarily used on computers manufactured by Microsoft.

A LAN (Local Area Network) is a network that connects computers within a limited geographic area, such as a building or a campus. It is designed to facilitate communication and resource sharing among devices in close proximity. Therefore, it is not used to connect computers in different cities, but rather for local connections.

The correct answer is that primary storage only temporarily stores data, while secondary storage does store data. Primary storage, also known as main memory or RAM, is used to store data that is actively being used by the computer's processor. It provides fast access to data, but is volatile and loses its contents when the computer is powered off. On the other hand, secondary storage, such as hard drives or solid-state drives, is used for long-term storage of data. It retains data even when the computer is turned off and provides larger storage capacity compared to primary storage.

Utility software is commonly used for security because it includes various tools and programs that help protect computer systems from threats such as viruses, malware, and unauthorized access.
