কম্পিউটাৰ ছফ্টৱেৰ , বা ছফ্টৱেৰ হ'ল কম্পিউটাৰে কি কৰিব লাগে সেয়া জনোৱাৰ বাবে ব্যৱহাৰ কৰা ডাটা অথবা কম্পিউটাৰ নিৰ্দেশাৱলীৰ একত্ৰিত সংকলন ৷ এয়া ভৌতিক হাৰ্ডৱেৰৰ (কম্পিউটাৰ হাৰ্ডৱেৰ) বিপৰীত ৷ ভৌতিক হাৰ্ডৱেৰৰ দ্বাৰাই কম্পিউটাৰ নিৰ্মাণ কৰা হয় ইয়েই প্ৰকৃত কামবোৰ কৰে ৷. In computer science and software engineering, computer software is all information processed by computer systems, programs and data. Computer software includes computer programs, libraries and related non-executable data, such as online documentation or digital media. Computer hardware and software require each other and neither can be realistically used on its own.
At the lowest programming level,[স্পষ্টীকৰণৰ প্ৰয়োজন] executable code consists of machine language instructions supported by an individual processor—typically a central processing unit (CPU) or a graphics processing unit (GPU). A machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also invoke one of many input or output operations, for example displaying some text on a computer screen; causing state changes which should be visible to the user. The processor executes the instructions in the order they are provided, unless it is instructed to "jump" to a different instruction, or is interrupted by the operating system. 2015 অনুসৰি[update], most personal computers, smartphone devices and servers have processors with multiple execution units or multiple processors performing computation together, and computing has become a much more concurrent activity than in the past.
