"Computer data storage is a technology consisting of computer components and recording media that are used to retain digital data."
The retention of encoded information over time.
Sensory Memory: The initial stage of memory processing where information is briefly registered in the sensory system.
Short-Term Memory: A temporary storage system that is limited in capacity and duration.
Long-Term Memory: A relatively permanent storage system that can hold an unlimited amount of information for an extended period.
Encoding: The process of transforming sensory input into a form that can be stored in memory.
Retrieval: The process of accessing and using stored information.
Maintenance rehearsal: Repetition of information to keep it in short-term memory.
Elaborative rehearsal: Processing information deeply and relating it to other information to enhance retention.
Chunking: Grouping individual pieces of information into meaningful units to improve memory capacity.
Mnemonics: Memory aids, such as acronyms or rhymes, to improve retention.
Retrieval cues: Stimuli that help guide the retrieval of information from memory.
Context-dependent memory: The tendency to remember information more easily when in the same context or environment as when it was learned.
State-dependent memory: The tendency to remember information more easily when in the same emotional or physiological state as when it was learned.
Procedural memory: Memory for skills and habits.
Declarative memory: Memory for facts and events.
Semantic memory: Memory of general knowledge and facts.
Episodic memory: Memory of specific events or experiences.
Retrograde amnesia: Loss of memory for events that occurred prior to an injury or trauma.
Anterograde amnesia: Inability to form new memories following an injury or trauma.
Consolidation: The process by which memories are strengthened and stabilized over time.
Memory impairment: Loss or decline in memory function, often due to injury, illness, or aging.
Sensory Memory: The initial stage of memory where sensory information is stored only momentarily, in a raw and unprocessed form.
Short-Term Memory: The type of memory that temporarily stores and processes a limited amount of information for immediate use (typically up to 30 seconds).
Long-Term Memory: The type of memory that stores information for a long period of time (from minutes to years) that can be retrieved on demand when needed.
Episodic Memory: A type of long-term memory that is responsible for storing events and personal experiences in a chronological sequence.
Semantic Memory: A type of long-term memory that is responsible for the encoding, storage, and retrieval of factual knowledge and general information about the world.
Explicit Memory: A type of long-term memory that involves conscious and intentional retrieval and recall of information.
Implicit Memory: A type of long-term memory that occurs without conscious awareness and includes skills, habits, and procedures.
Procedural Memory: A type of implicit memory that involves the recall of motor skills and habits.
Declarative Memory: A type of explicit memory that can be consciously declared, including episodic and semantic memories.
Working Memory: A component of the short-term memory system that actively holds information for immediate processing and manipulation.
Retrograde Amnesia: The loss of memory of events that occurred prior to a brain injury or trauma.
Anterograde Amnesia: The inability to form new memories after the occurrence of brain injury or trauma.
Eidetic Memory: A type of exceptional memory that involves vivid and accurate recall of visual information in great detail.
Flashbulb Memory: A type of memory that is highly emotional and vivid, usually associated with a significant and unexpected event.
Autobiographical Memory: A type of long-term memory that involves the recall of personal experiences, including episodic and semantic memories.
"It is a core function and fundamental component of computers."
"The central processing unit (CPU) of a computer is what manipulates data by performing computations."
"In practice, almost all computers use a storage hierarchy, which puts fast but expensive and small storage options close to the CPU and slower but less expensive and larger options further away."
"Generally, the fast technologies are referred to as 'memory'."
"Slower persistent technologies are referred to as 'storage'."
"Even the first computer designs, Charles Babbage's Analytical Engine and Percy Ludgate's Analytical Machine, clearly distinguished between processing and memory."
"Babbage stored numbers as rotations of gears."
"Ludgate stored numbers as displacements of rods in shuttles."
"The CPU consists of two main parts: The control unit and the arithmetic logic unit (ALU)."
"The control unit controls the flow of data between the CPU and memory."
"The ALU performs arithmetic and logical operations on data."
"The control unit controls the flow of data between the CPU and memory."
