Computer Storage Devices Quiz!

Memory cards are solid electronic data storage devices that are widely used in cameras, telephones, laptops, music players, and video game consoles. They are compact and portable, making them convenient for storing and transferring data. Memory cards come in various formats such as SD, microSD, and CompactFlash, and have different storage capacities ranging from a few gigabytes to several terabytes. They are commonly used to store photos, videos, music, and other digital files, providing a reliable and easily accessible storage solution for electronic devices.

A USB (Universal Serial Bus) is a removable and rewritable electronic data storage device that can be plugged into almost any PC. It is a popular and widely used technology for transferring and storing data. USBs are small, portable, and have a large storage capacity, making them convenient for carrying files and transferring data between devices. They have largely replaced older storage devices like floppy disks and are more versatile than memory cards, as they can be easily connected to different devices without the need for additional adapters.

ROM stands for Read Only Memory. It is a type of computer memory that stores data permanently and cannot be modified or erased. The data in ROM is pre-programmed during manufacturing and remains intact even when the computer is turned off. It is used to store essential instructions and data that are necessary for the computer to boot up and perform basic functions. Unlike other types of memory, ROM is non-volatile and retains its data even without power. Therefore, the correct answer is Read Only Memory.

A CD-ROM (Compact Disk Read-Only Memory) is a type of compact disk where data is permanently written during manufacturing and cannot be altered or erased. CD-R (Compact Disk Recordable) can be written once, but not erased, while CD-RW (Compact Disk Rewritable) allows data to be written, erased, and rewritten multiple times. Therefore, the correct answer is CD-ROM, which contains data that is unchangeable.

CD-RW stands for Compact Disk Rewritable. It is an optical disk that allows users to save and erase data multiple times. Unlike CD-R (Compact Disk Recordable) which can only be written once, CD-RW provides the flexibility to rewrite and modify the data on the disk. This makes it a more versatile and reusable option for storing and managing data. CD-ROM, on the other hand, stands for Compact Disk Read-Only Memory and refers to a type of disk that can only be read and not written or modified.

The internal storage of a computer refers to the physical location where data is stored within the computer system. In this case, the correct answer is "Hard Disk" because it is a type of internal storage device commonly used in computers. Hard disks provide a large amount of storage space and are typically used to store the operating system, software applications, and user data. They consist of one or more spinning disks, or platters, which are coated with a magnetic material to store data.

A byte is the basic unit of measurement for storage in computer science. It is a sequence of 8 bits, and it can represent a single character or a small amount of data. The other options, kilobyte and bit, are also units of measurement in computer science, but they are not the basic unit like a byte. A kilobyte is equal to 1024 bytes, and a bit is the smallest unit of information in computing. Therefore, the correct answer is byte.

The correct answer is 1.4 MB. A floppy disk is a storage device that was commonly used in the past. It had a storage capacity of 1.4 MB, which means it could store approximately 1.4 million bytes of data. This amount of storage was sufficient for storing small files and documents, but it is significantly lower compared to modern storage devices such as USB flash drives or hard drives.

A Zip Disk is a small portable disk that is thicker than a floppy disk and requires a special drive connected to the computer. It is enclosed in a plastic cover, making it more durable and less prone to damage compared to a floppy disk. The special drive is necessary because the Zip Disk uses a different technology and storage capacity than a floppy disk or a CD-R.

A CD-R (Compact Disc-Recordable) is an optical disk that allows you to save data only once, even if the entire space available is not used. Unlike a CD-RW (Compact Disc-ReWritable), which can be erased and rewritten multiple times, a CD-R is a write-once disk. Once data is written onto a CD-R, it cannot be modified or erased, making it a suitable choice for permanent storage of data. A CD-ROM (Compact Disc-Read Only Memory) is a pre-recorded optical disk that cannot be written onto at all.
