Need help with my course on memory mapping and stuff

AI Thread Summary
Memory mapping involves the organization of memory addresses and how data is accessed in various types of memory, including main memory, cache memory, and associative memory. Understanding memory hierarchy is crucial, as cache memory acts as a faster storage option that mirrors main memory, enhancing data retrieval speeds. For beginners seeking detailed explanations, online resources such as Wikipedia can provide foundational knowledge on memory mapping concepts. It's important to explore specific terms like "associative memory" for a clearer understanding. Comprehensive tutorials are available online to help grasp these fundamental topics in computer organization.

I have got a begginner's course in computer organisation this semester. The course consists of the basic stuff like types of memories and memory hierarchy with the detailed description of each etc etc.
Now, what i really don't get is memmory mapping and how exactly data is read and written on main memory, cache memory or may be associative memory.
Is there any tutorial available on the internet that can describe all this in detail but which starts from a basic level?
Please don't suggest any reference book, i have lost my library card :(

Try typing terns like associative memory into Google.

Memory mapping refers to a number of things.
For a start you can try here.

Cache memory is a copy of main memory. Usually this is controlled by the hardware designer.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
