The difference between virtual and physical memory is that virtual memory refers to memory space while physical memory are chips like RAM. The memory space for virtual memory is made by operating system when there is insufficient physical memory.
Sensory memory is when you use your senses to remember stuff (smell, hear, taste, touch, and see).Long term memory is information stored in the brain and retrievable over a long period of time.
what is the difference between short term memory, long term memory and sensory memory with short term memory information can be remembered 2o sec after seeing touching smelling ect. the information. the information can also be remembered as long as you are thinking about it sensory memory can only be remembered if the object is in front of you. such as a stranger, you can remember then but as soon as the walk away you can remember what they were wearing how they smelled ect... long term memory can be remembered through out a life time
The results of the memory test
A literal is a value that can be assigned to a constant or a variable. A constant is a named memory address in which only one value can be stored. The value must be assigned at compile time and cannot change at runtime. A variable is a named memory address in which any binary value can be stored. Variables can be initialised at compile time but can change value at runtime. Examples: int i = 42; // assign the literal value 42 to the variable i. const float pi = 3.14; // assign the literal value 3.14 to the constant pi. char c[] = "Hello world"; // assign the string literal to the character array c.
A user variable is a memory which is used in specific function or functionality. A system variable is kinda of generic, accessible to all users of the system. It does not bind to specific process as such.
An object is the actual storage space in memory in which some collection of data resides.A reference variable is a variable which refers to the memory location of an object.Look at the pseudocode below:Object obj = new Object();Here obj is the reference variable, and the data to which it refers is the object.

what is the difference between the memory store model and the working memory model?
The declaration 'int a' both declares the variable of 'a' and allocates memory for it. When you use 'extern' you are referring to a variable called 'a' that has its memory allocated in another module. The actual variable 'a' is not in the same compilation unit as the current one being compiled. Where the variable 'a' is located is resolved by the linker. When using 'extern' you state your intent to use a variable called 'a', but it doesn't reserve any memory for it in the current module.
A variable basically holds a single type literal in memory through defining its type, declaring it, and setting a value to it. If you meant reference variables, they are variables which refer to the memory location of an object previously set.An object is the actual storage space in memory in which some collection of data resides (is stored). Objects 'live' in memory spaces known as 'heaps'.
constant means data item whose value cannot be altered or change. whereas variable is named storage location whose value can be manipulated during program run.

Reference VariableIt does not have separate memory other than variableIt is just an alias created to existing variableIt is not present C languagePointer VariableIt has separate memory other than variableIt actually stores address of the variableIt is present in C as well as C++.
Memory is microchip; address are processor board slots
difference between register and memory location
if a variable is of value type memory is allocated on stack memory.. if it is of reference type,memory is allocated on heap memory..
