Ответы на вопрос

The time required for the computer to locate and transfer data in the storage device is called the data access time.
Correct answer: b) access
Explanation: Data access time refers to the time it takes for the storage device to locate and transfer data to the CPU. This term is widely used in the context of storage technologies like RAM, SSDs, and hard drives.Electronic memories have no moving parts.
Correct answer: a) electronic
Explanation: Unlike mechanical or electromechanical memories, electronic memories such as RAM and SSDs do not rely on moving components, making them faster and more reliable.Magnetic cores were the main elements used for primary memory in digital computers for many years.
Correct answer: a) cores
Explanation: Magnetic core memory was a widely used form of primary memory in the mid-20th century before semiconductor memories became predominant.MOS is more commonly used for memory at present.
Correct answer: b) MOS
Explanation: MOS (Metal-Oxide-Semiconductor) technology dominates modern semiconductor memory, including RAM and flash storage, due to its efficiency and scalability.Magnetic disks constitute the secondary storage media.
Correct answer: c) secondary
Explanation: Magnetic disks, such as hard drives, are classified as secondary storage because they provide long-term data storage as opposed to primary memory, which is temporary and faster.Data are stored in binary codes in primary as well as in secondary storage.
Correct answer: b) binary
Explanation: Binary code, consisting of 0s and 1s, is the fundamental way data is represented in all modern computing devices, whether in primary (RAM) or secondary (hard drives, SSDs) storage.Data access time is shorter in electronic memories than that in electromechanical memories.
Correct answer: c) shorter
Explanation: Electronic memories, such as RAM, are significantly faster than electromechanical memories like hard drives, which rely on moving parts.Electronic memories have larger capacities for data storage.
Correct answer: b) larger
Explanation: Modern electronic memories can store massive amounts of data due to advancements in semiconductor technology, which has enabled increased density and miniaturization.
