No. Optical storage is something that can be read using the aid of light. So CD's, DVD's would be examples of optical storage.
Spinning hard drives are not optical either. They use magnetism to store data.

∙ 9y agoCD, DVD and LaserDisc drives are all optical drives. Anything that uses a laser to read or write binary data is an optical storage device. The binary data is recorded as a sequence of 'pits' and 'lands' as the disc rotates. A pit does not reflect light but a land does, thus giving the two possible states for each binary digit. The light has to be focused and calibrated extremely accurately, hence the use of laser light. Data is recorded in a series of tightly-packed concentric circulars, from the inside to the outside.

What physical storage media holds program variables during execution?
Memory (RAM) usually What holds program variables during execution, but any storage medium can be used to store variables, including magnetic, optical and solid state drive.
Storage pool in datastructure?
Storage pool is collection of free linked list in the memory.
Definition of memory and its types?
Memory refers to the physical devices used to store programs (sequences of instructions) or data (e.g. program state information) on a temporary or permanent basis for use in a computer or other digital electronic device. Computer Memory is two types as Primary Memory and Secondary Memory at the base of uses. The term primary memory is used for the information in physical systems which function at high-speed (i.e. RAM), as a distinction from secondary memory, which are physical devices for program and data storage which are slow to access but offer higher memory capacity. When data of Primary Memory stored on secondary memory is called "virtual memory".Primary MemoryThe term "memory" is often (but not always) associated with addressable semiconductor memory, i.e. integrated circuits consisting of silicon-based transistors and used as primary memory. Primary storage (or main memory or internal memory), often referred to simply as memory, is the only one directly accessible to the CPU. The CPU continuously reads instructions stored there and executes them as required. Any data actively operated on is also stored there in uniform manner. RAM used for primary storage is also volatile, i.e. they lose the information when not powered). Cash Memory is also a super fast then RAM and it working for only processor.There are two main types of semiconductor memory: volatile and non-volatile.Examples of non-volatile memory are flash memory (sometimes used as secondary, sometimes primary computer memory) and ROM/PROM/EPROM/EEPROM memory (used for firmware such as boot programs). Examples of volatile memory are primary memory (typically dynamic RAM, DRAM), and fast CPU cache memory (typically static RAM, SRAM, which is fast but energy-consuming and offer lower memory capacity per area unit than DRAM).Secondary MemoryThe term "storage" is often (but not always) used in separate computers of traditional secondary memory such as tape, magnetic disks and optical discs (CD-ROM and DVD-ROM). Secondary storage (also known as external memory or auxiliary storage), differs from primary storage in that it is not directly accessible by the CPU. The computer usually uses its input/output channels to access secondary storage and transfers the desired data using intermediate area in primary storage. Secondary storage does not lose the data when the device is powered down-it is non-volatile. Hard disk, CD and DVD drives are usually used as secondary storage. Some other examples of secondary storage technologies are: flash memory (e.g. USB flash drives or keys), floppy disks, magnetic tape, paper tape, punched cards, standalone RAM disks, and Iomega Zip drives.
What is contiguous storage allocation?
Contiguous means to share an edge or boundary, touching, adjacent, neighbouring and so on. Thus contiguous storage allocation is any allocation that consumes two or more contiguous storage elements. In the case of contiguous memory allocation, this means two or more contiguous memory addresses are allocated. A one-dimensional array is an example of a contiguous memory allocation, where one array element (a data type) is immediately followed by the next.
What is fragmentation and defragmentation in memory management?
fragmentashon is a phenomena in which storage sapce is used inefficetively,reducing storage capacity

What is the purpose of memory?
The purpose of secondary memory is storage of data that is not immediately needed for processing by the CPU. Examples of secondary devices are hard drives and optical drives.
What is optical memory?
Optical memory is an early form of computer memory. It involves the use of an optical system for the writing and reading of data to and from a computer's main memory.
