Computing is any task-oriented sgp hari ini live activity using, gaining the advantage of, or creating computing machines. It involves the study and experiment of algorithms and design of both software and hardware. It also includes both scientific and engineering aspects. Computers are used in many fields of science and engineering to carry out a number of tasks efficiently. Examples include communication systems, financial services, manufacturing, transportation, weather prediction, and manufacturing performance analysis.

Computers are built on microprocessors and they execute instructions provided by software programs written for them. The execution environment in computing is rather complex and it consists of various hardware and non-hardware elements such as personal computers, input and output devices, storage media, networks, memory, and input/output devices. Most modern day computing machines are highly customizable and they can also be net-centric. They have a large capacity for data storage and processing, high speed internet connections, personal computer hardware, digital camera, video camera, mobile phone, compact disc and other digital memory devices, personal digital assistants, digital imaging devices, media servers, personal digital audio devices, digital signal processor, voice processors, game consoles, digital signage, and the like.

Computers were first developed to solve some specific problems but today they play a greater role in our everyday lives. There are different types of computing such as mission-critical computing, commercial off-the-shelf computing, system maintenance, consumer computing, embedded systems, supercomputers and virtualization. It is very important that we are able to control and manipulate computers through appropriate programming languages such as C/C++, Java, Perl, Python, Ruby, shell, assemblers, and so on. A lot of scientific works are carried out with the help of computing because it makes it much easier for scientists to experiment and obtain results accurately. There are even some companies that provide computing services on rent for business purposes.
