Computer memory can be divided into two sections. The section common to all computers is the main memory. A second section, called the file or secondary memory, is often present to store large amounts of information if needed.
The main memory is composed of semiconductor devices and operates at much higher speeds than does the file memory. Typically a word or set of data can be stored or retrieved in a fraction of a microsecond from the main memory.
We shall limit our discussion to semiconductor main memory. There are two broad classifications within semiconductor memories, the read-only memory (ROM) and the read-write memory (RWM). The latter is also called a RAM to indicate that this is a random-access memory. Random access simply means that...
存儲(chǔ)器是能夠存儲(chǔ)一位或多位信息的媒體或裝置。在二進(jìn)制系統(tǒng)中，一位以?xún)煞N可能狀態(tài)之一進(jìn)行存儲(chǔ)，分別代表1或0。觸發(fā)器就是一位存儲(chǔ)器的例子。配有合適的傳送裝置和讀寫(xiě)電路的磁帶是大存儲(chǔ)器的另一個(gè)極端的例子，存儲(chǔ)能力在10億位以上。?
計(jì)算機(jī)的存儲(chǔ)器可以分成兩部分。所有計(jì)算機(jī)都有的部分是主存儲(chǔ)器。第二部分稱(chēng)為 文件存儲(chǔ)器或輔助存儲(chǔ)器，在需要的時(shí)候，常用以存儲(chǔ)大量的信息。
主存儲(chǔ)器是由半導(dǎo)體器件組成的，其運(yùn)行速度比文件存儲(chǔ)器快得多。一般來(lái)說(shuō)，以零點(diǎn)幾微秒的時(shí)間即可對(duì)主存儲(chǔ)器存或取ー個(gè)字或一組數(shù)據(jù)。
我們只討論半導(dǎo)體型主存儲(chǔ)器。半導(dǎo)體型存儲(chǔ)器分為兩大類(lèi)：只讀存儲(chǔ)器(ROM)和讀寫(xiě)存儲(chǔ)器(RWM)。后者也稱(chēng)為RAM——隨機(jī)存取存儲(chǔ)器。隨機(jī)存取的意思只是說(shuō)……
在這段文章的譯文中，譯者將普通詞匯memory，按照專(zhuān)業(yè)術(shù)語(yǔ)的要求譯成“存儲(chǔ)器”，并堅(jiān)持ー貫性原則，在翻譯main memory，file memory, and secondary memory， the read-only memorv (ROM)，the read-write memory (RWM)，random-access memory. 等詞時(shí)，將其中的memory始終保持一致地譯成“存儲(chǔ)器”。
