FAQs on Types of Memory Video Lecture - Embedded Systems (Web) - Computer Science Engineering (CSE)

1. What are the different types of memory?
Ans. There are several types of memory, including sensory memory, short-term memory, and long-term memory. Sensory memory holds information from our senses for a brief period, short-term memory stores information temporarily, and long-term memory stores information for an extended period.
2. How does sensory memory work?
Ans. Sensory memory is a type of memory that holds information from our senses for a very short duration, typically less than a second. It allows us to briefly retain and process sensory information before it either fades away or gets transferred to short-term memory for further processing.
3. What is the capacity of short-term memory?
Ans. Short-term memory has a limited capacity and can hold a small amount of information for a short duration, typically around 7 ± 2 items. This means that we can only hold around 5 to 9 pieces of information in our short-term memory at a time.
4. How does information transfer from short-term memory to long-term memory?
Ans. Information is transferred from short-term memory to long-term memory through a process called encoding. Encoding is the process of converting information from short-term memory into a format that can be stored and retrieved in long-term memory. This can occur through rehearsal, elaboration, or other encoding strategies.
5. What can affect the retrieval of information from long-term memory?
Ans. Several factors can affect the retrieval of information from long-term memory, including interference from other memories, the strength of the initial encoding, and the availability of retrieval cues. Additionally, factors such as stress, distractions, or lack of attention during encoding can also impact the retrieval process.
