… It is easier to write programs if a computer has only one type of memory and can access it uniformly. This is made possible by the concept of uniform addresses (which can be one- or two-dimensional). For example, on a computer with a 32-bit word unit, a 32-bit address can represent 4 gigabytes of memory. …

From [Memory Device]

...For images, the amount of storage varies greatly depending on the resolution and number of colors, but even with compression, tens to hundreds of kilobytes are needed to store one still image, and hundreds of kilobytes to several megabytes per second are needed to store a video. In most storage devices, as shown in Figure 1, a series of numbers called addresses (also called house numbers) are assigned to groups of several digits that store binary numbers on the storage medium, and data can be written to or read from a specific location by specifying the address. An address is like an address consisting of numbers only, and reading and writing information is like putting information into or taking information out of a house (memory element) with a specified address. ...

…画像の場合は解像度や色数などによって大幅に変化するが,圧縮しても1枚の静止画を記憶するには数十~数百キロバイト,動画を記憶するには1秒あたり数百キロバイト~数メガバイト程度の容量が必要である。 大半の記憶装置においては,図1のように記憶媒体における二進数を記憶する場所を何桁かずつまとめたものに対してアドレス(番地ともいう)と呼ばれる一連の番号をつけ,アドレスを指定することによって特定の場所に書き込んだり,そこから読み出したりする。アドレスは数字だけの住所のようなものであり,情報の読み書きは住所が指定された家(記憶素子)に情報を入れたり,そこから情報を出したりするようなものである。…

…大きなメモリーのどの部分に所望のデータが入っているかを示すために,メモリーに番号を振る。この番号を番地(アドレス)と呼ぶ。一つの番地に一つのデータ(いまの場合,数)を格納する。…
