در زندگی های امروزی کمتر کسی وجود دارد که با نقش رایانه و جایگاه آن در زندگی آشنایی نداشته باشد. دنیایی که ما در آن هستیم و پیش روی ما قرار دارد، دنیای اطلاعات است و نقش کامپیوتر در آن بسیار اهمیت دارد که بین انسانها و جوامع ارتباطی ساده و راحت را فراهم کرده است و البته اینکه یکی از تکنولوژی های بسیار مفید در زمینه آموزش می باشد. ما در این مطلب به طور مختصر تعریف کامپیوتر را به زبان انگلیسی و فارسی به شما توضیح می دهیم . بازیابی ایمیل
در گذشته در زبان فارسی به کامپیوتر «مغز الکترونیکی» می گفتند که ابن واژه زمانی کاربرد داشت که اولین کامپیوتر وارد ایران شد، واژه رایانه اخیرا رایج شده و کلمه فارسی می باشد. اما در انگلیسی تا اکنون واژه های هم ارزشی به کار رفته که معانی متفاوت داشتند،در انگلیسی واژهها و تعابیر گوناگونی استفاده میشود، بهعنوان مثال دستگاه داده پرداز یا data processing machine

A computer is a device that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming. Modern computers have the ability to follow generalized sets of operations, called programs. These programs enable computers to perform an extremely wide range of tasks
Computers are used as control systems for a wide variety of industrial and consumer devices. This includes simple special purpose devices like microwave ovens and remote controls, factory devices such as industrial robots and computer-aided design, and also general purpose devices like personal computers and mobile devices such as smartphones
Early computers were only conceived as calculating devices. Since ancient times, simple manual devices like the abacus aided people in doing calculations. Early in the Industrial Revolution, some mechanical devices were built to automate long tedious tasks, such as guiding patterns for looms. More sophisticated electrical machines did specialized analog calculations in the early 20th century. The first digital electronic calculating machines were developed during World War II. The speed, power, and versatility of computers have been increasing dramatically ever since then
Conventionally, a modern computer consists of at least one processing element, typically a central processing unit (CPU), and some form of memory. The processing element carries out arithmetic and logical operations, and a sequencing and control unit can change the order of operations in response to stored information. Peripheral devices include input devices (keyboards, mice, joystick, etc.), output devices (monitor screens, printers, etc.), and input/output devices that perform both functions (e.g., the 2000s-era touchscreen). Peripheral devices allow information to be retrieved from an external source and they enable the result of operations to be saved and retrieved
