求翻译：计算机1945年出现，它最早是用于科学计算，它的计算速度快、资源共享、运算精度高、具有记忆和逻辑判断能力、可靠性、安全性高等特点加快了它的发展速度；它可划分四个阶段，电子管时代、晶体管时代、集成电路时代、超大规模集成电路时代；机器语言是电脑能直接接收处理的二进制语言；汇编语言是用助记符表示电脑操作指令的面向硬件的语言，比高级语言要低级，比机器语言高级；高级语言的表达更接近人类语言，比较易写、易懂，程序编译器编译后才能执行。是什么意思？

Computer in 1945 appeared, it was first used in scientific computing, it's calculating speed, resource sharing, operation and high precision, with the memory and logic capabilities, reliability, high security and other features to speed up its pace of development; it can be divided four stages, tube
