RAM
Random access memory (RAM - random access device) - memory designed for time-to-hour storage of data and commands necessary for the processor to carry out operations.
RAM transmits commands and data to the processor directly or through cache memory.
Each part of the operative memory has its own individual address.
Slide 14
Current RAM is dynamic random access memory (DRAM).
The concept of memory with sufficient access transfers that the process of data mining does not guarantee the order in which it is distributed.
Memory middle - a part of the memory EOM for saving 1 machine word (number) or another part (for example, 1 byte).
The total amount of memory in all devices means the capacity of the EOM memory.
In 1973, IBM released the hard drive model 3340, which for the first time combined the disk platters and the heads for reading in one integral housing.
During its development, engineers used a short internal name “30-30”, which meant two modules (for the maximum configuration) of 30 MB each.
Kenneth Houghton, the head of the project, based on the designation of the popular Myslyovsky towel Winchester 30-30, called this disk a Winchester.

The system board contains the information exchange highway, it has connectors for installing a processor and RAM, as well as slots for installing controllers for external devices (video card,, sound card merzheva map and others). The processor will be based on a large integrated circuit, which includes a large number of elements - diodes, transistors, capacitors, resistors, etc.
This complex system is the brain of a computer.
The processor processes information that is sent to a dual view and is displayed on the motherboard.

Slide 29
Therefore, the address bus is single-directional.
The width of the address bus means the amount of addressable memory - the address space, which is the number of single-byte spaces in the RAM that can have unique addresses.
The number of addressed memory centers can be analyzed using the following formula: N = 2I, where I is the capacity of the address bus.
The address bus capacity for current personal computers is set to 36 bits.
