In memory address zero we have 0010 1110.

在内存地址零中，我们有 0010 1110。

Next we have a STORE instruction that saves Register A into memory address 13.

接下来我们有一条 STORE 指令，将寄存器 A 保存到内存地址 13 中。

The very first instruction to be executed, the one at memory address 0, was 0010 1110.

第一条要执行的指令，即内存地址 0 处的指令，是 0010 1110。

When Program A reads memory address 999, that does coincidentally map to physical memory address 999.

当程序 A 读取内存地址 999 时，它恰好映射到物理内存地址 999。

For this, we use an instruction address register, which as the name suggests, stores the memory address of the current instruction.

为此，我们使用一个指令地址寄存器，顾名思义，它存储当前指令的内存地址。

Program A might get allocated memory addresses 0 through 999, and Program B might get 1000 through 1999, and so on.

程序 A 可能分配到 0 到 999 的内存地址，程序 B 可能分配到 1000 到 1999，依此类推。

But if Program A reads the very next value in memory, at address 1000, that gets mapped behind the scenes to physical memory address 2000.

但是，如果程序 A 读取内存中地址 1000 处的下一个值，该值将在幕后映射到物理内存地址 2000。

Continuing our restaurant example, let's say the processor has finished totalling up all of the sales for the day, and wants to store the result in memory address 150.

继续我们的餐厅示例，假设处理器已完成当天所有销售额的总计，并希望将结果存储在内存地址 150 中。

When you had finally entered your whole program into memory, you would toggle the switches, move back to memory address zero, press the run button, and watch the little lights blink.

当你最终将整个程序输入内存时， 你会拨动开关，回到内存地址零， 按下运行按钮， 然后看着小灯闪烁。

This virtualization of memory addresses is even more useful for Program A, which in our example, has been allocated two blocks of memory that are separated from one another.

这种内存地址的虚拟化对于程序 A 更有用，在我们的示例中， 程序 A 已分配了两个彼此分开的内存块。
