Quiz Secondary Storage Devices

Explanation
A secondary storage device refers to data storage that is not currently in a computer's primary storage or memory. This can include devices such as hard drives, solid-state drives, external drives, and optical discs. These devices are used to store data for long-term or permanent storage, allowing the computer to access the information as needed. Unlike primary storage or memory, which is volatile and loses data when the computer is powered off, secondary storage retains data even when the power is turned off.

Explanation
A floppy disk is considered a secondary storage device because it is used to store data that is not actively being used by the computer. It is a removable storage medium that can store a relatively small amount of data. Unlike primary storage devices such as RAM, which provide temporary storage for data that is actively being used by the computer, a floppy disk is used for long-term storage and can be easily transported and accessed on different computers. Therefore, it falls under the category of secondary storage devices.

Explanation
Secondary storage refers to the storage devices that are used to store data and programs permanently. It is called "secondary" because it is not directly accessible by the CPU, unlike primary storage (main memory). Instead, data is transferred between secondary storage and main memory when needed. "Auxiliary storage" is another term used to describe secondary storage, emphasizing its supportive role in providing additional storage capacity for the computer system.

Explanation
Secondary storage refers to storage devices that are not constantly accessible by the computer. This means that these devices are not directly connected to the computer's main processing unit and cannot be accessed as quickly as primary storage devices. Examples of secondary storage devices include hard disk drives, solid-state drives, and optical drives. These devices are used for long-term storage of data and are typically slower in terms of data access compared to primary storage devices like RAM. Therefore, the statement "Secondary storage refers to storage devices that are not constantly accessible by the computer" is true.

Explanation
USB Flash Drives are examples of secondary storage devices, not primary storage devices. Primary storage devices, also known as main memory or internal memory, are used to store data that is actively being accessed by the computer's processor. This includes the computer's RAM (Random Access Memory) and cache memory. USB Flash Drives, on the other hand, are external storage devices that are typically used for long-term storage and data transfer. They are considered secondary storage devices because they are not directly accessed by the computer's processor.

Explanation
RAM stands for Random Access Memory. This is a type of computer memory that allows data to be stored and accessed in any order, rather than sequentially. It is called "random access" because the computer can directly access any piece of data stored in RAM, without having to search through the entire memory. This makes RAM much faster to read and write data compared to other types of memory.

Explanation
ROM stands for Read Only Memory. It is a type of computer memory that stores data that cannot be modified or erased once it has been programmed. This memory is non-volatile, meaning it retains its data even when the power is turned off. ROM is commonly used to store firmware, which contains the permanent instructions for a computer or electronic device. It is called "Read Only" because the data can only be read and not written or modified.

Explanation
The statement is true because there are indeed 5 criteria for rating secondary storage devices. These criteria include capacity, speed, reliability, cost, and portability. Capacity refers to the amount of data that can be stored on the device, speed refers to the rate at which data can be accessed and transferred, reliability refers to the durability and stability of the device, cost refers to the price of the device, and portability refers to the ease of carrying and moving the device.

Explanation
The given statement is false. The two most common types of floppy disks are actually 5 1/4 and 3 1/2 inch floppy disks. The sizes mentioned in the statement (5 1/2 and 3 3/4) do not correspond to any standard floppy disk sizes.

Explanation
A floppy disk is indeed commonly known as "floppies". This term is often used colloquially to refer to the small, portable magnetic storage disks that were popular in the past. The term "floppies" derives from the flexible nature of the disk and its ability to be inserted and removed from disk drives. While floppy disks are less commonly used today, the term "floppies" is still recognized and understood by many people.
