Address line 1 line 2 date
1 - The program, in conjunction with DOS sends an electrical discharge through the line address (line address), which is
a filament microscopic conductive material applied to the chip RAM.
The discharge record identifies where the data between
the various lines of addressing on-chip RAM.
2 - on the memory chip RAM where the data can be recorded, the electrical pulse activates (closes) a transistor
connected to the data line (data line).
The transistor is basically an electrical switch microscopic.
3 - While the transistors are triggered, the program sends electricity discharges with selected data rows.
Each discharge represents a bit - 1 or 0 in the native language of the processor, and the information unit smaller than the
computer can handle.
4 - When the electrical impulse reaches a line addressing (adress line) with transistor turned on, the pulse passes through
closed transistor transistor (closed) and supplies a capacitor, an electronic device that stores electricity.
This
process repeats continuously to renew the charge on the capacitor, otherwise this would be weakened.
When the
computer is turned off, all capacitors lose their charge.
Each capacitor charged with the line address
represents bit 1.
An uncharged capacitor represents bit 0.
The PC uses bits 1 and 0 as binary numbers to
store and manipulate all the information.
Transistor Transistor closed open
Note - Since the computer works only with binary numbers, a capital A is stored in RAM and on disk as number
binary 01000001, and a capital B becomes 01000010.
The illustration above shows the letter stored as a 4 byte on-chip
RAM.
0 first of the eight capacitors with line addressing is not loaded, the second capacitor is charged;
the following five are not, and the eighth is.
