电子计算器是一种固定程序的小型电子计算装置,它不仅可以进行算术运算、函数运算、统计运算,还可以编制简单的程序。从这点看来,它的性能已接近微型机。但后者的计算结果一般是由屏幕显示的。目前我们在电子计算机(电脑)方面用得最多的是微型机和袖珍机。所谓袖珍计算机是因为它体积小,可以方便携带,但是它一般缺乏显示屏幕,不便检查所编程序的错误,如日本SHARP公司的PC—1500机。
Electronic calculator is a fixed program of small electronic computing device, it can not only arithmetic operations, function operations, statistical operations, but also the preparation of simple procedures. From this point of view, it’s performance is close to the micro-machine. However, the calculation result of the latter is generally displayed on the screen. Currently we use the most computers and microcomputers. The so-called pocket computer because of its small size, you can easily carry, but it generally lacks display screen, inconvenience to check the programmed error, such as Japan’s SHARP PC-1500 machine.
