What is computer block diagram
A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks.
They are heavily used in engineering in hardware design, electronic design, software design, and process flow diagrams..
What are the 2 types of computer memory
There are basically two kinds of internal memory: ROM and RAM. ROM stands for read-only memory.
What is RAM and ROM with example
RAM and ROM are both types of computer memory. RAM is used to store computer programs and data that CPU needs in real time. RAM data is volatile and is erased once computer is switched off. … ROM stands for Read Only Memory.
What are the four types of memory
4 Types of Memory: Sensory, Short-Term, Working & Long-Term.
Which is the main memory of computer
Main memory is the primary, internal workspace in the computer, commonly known as RAM (random access memory). Specifications such as 4GB, 8GB, 12GB and 16GB almost always refer to the capacity of RAM. In contrast, disk or solid state storage capacities in a computer are typically 128GB or 256GB and higher.
Which is the first step of memory
Sensory memorySensory memory is the first stage of memory. Its purpose is to give your brain time to process the incoming information. Sensory memory is not consciously controlled.
What is a photogenic mind
Eidetic or photographic memory Eidetic imagery is the ability to remember an image in so much detail, clarity, and accuracy that it is as though the image were still being perceived. … Contrary to ordinary mental imagery, eidetic images are externally projected, experienced as “out there” rather than in the mind.
What is memory Short answer
Memory refers to the processes that are used to acquire, store, retain, and later retrieve information. There are three major processes involved in memory: encoding, storage, and retrieval. Human memory involves the ability to both preserve and recover information we have learned or experienced.
What is a memory definition
Memory is the faculty of the brain by which data or information is encoded, stored, and retrieved when needed. It is the retention of information over time for the purpose of influencing future action.
What are the 3 types of memory
The three main forms of memory storage are sensory memory, short-term memory, and long-term memory. Sensory memory is not consciously controlled; it allows individuals to retain impressions of sensory information after the original stimulus has ceased.
What is computer memory explain
A memory is just like a human brain. It is used to store data and instructions. Computer memory is the storage space in the computer, where data is to be processed and instructions required for processing are stored. The memory is divided into large number of small parts called cells.
How memory is formed
The brain simmers with activity. Different groups of neurons (nerve cells), responsible for different thoughts or perceptions, drift in and out of action. Memory is the reactivation of a specific group of neurons, formed from persistent changes in the strength of connections between neurons.
Is ROM a memory
ROM is an acronym for Read-Only Memory. It refers to computer memory chips containing permanent or semi-permanent data. Unlike RAM, ROM is non-volatile; even after you turn off your computer, the contents of ROM will remain. Almost every computer comes with a small amount of ROM containing the boot firmware.
What is computer memory and its types
Computer memory is a generic term for all of the different types of data storage technology that a computer may use, including RAM, ROM, and flash memory. Some types of computer memory are designed to be very fast, meaning that the central processing unit (CPU) can access data stored there very quickly.

What is RAM and ROM in computer
RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer. Find out more about RAM.
What is the purpose of a memory
Memory is a system or process that stores what we learn for future use. Our memory has three basic functions: encoding, storing, and retrieving information. Encoding is the act of getting information into our memory system through automatic or effortful processing.
Why do we forget
The inability to retrieve a memory is one of the most common causes of forgetting. So why are we often unable to retrieve information from memory? One possible explanation of retrieval failure is known as decay theory. According to this theory, a memory trace is created every time a new theory is formed.
