In the immediate wake of World War II , for example, it was widely considered in the United States that technology was simply “applied science” and that to fund basic science was to reap technological results in due time. It has helped develop more advanced economies (including today’s global economy ) and has allowed the rise of a leisure class Many technological processes produce unwanted by-products known as pollution and deplete natural resources to the detriment of Earth’s environment Innovations have always influenced the values of a society and raised new questions of the ethics of technology Examples include the rise of the notion of efficiency in terms of human productivity , and the challenges of bioethics. Input device : usually a keyboard and mouse , the input device is the conduit through which data and instructions enter a computer.

If you’ve missed a Computing Full-time Programs information session, you can watch the full video. This includes the software, hardware and peripherals you need for your computing devices such as keyboards, monitors, RAM, a webcam and mouse.
Computer science (which is sometimes used as an umbrella term for all kinds of specialist study of computers and technology) involves core subjects such as the theory of computation, basic programming and the principles of computer hardware – among others. Personalise and boost the performance of your laptop, desktop, tablet or e-reader with Takealot’s range of computer accessories In this section you will find everything you need to get the most out of your computing devices, from wireless webcams to memory cards and including travel chargers , protective cases, speakers , and USB cables. Computer is an advanced electronic device that takes raw data as input from the user and processes these data under the control of set of instructions (called program) and gives the result (output) and saves output for the future use.
Mass storage devices store programs and data even when the power is off; they do require power to perform read and write functions during usage. Main memory is much faster than mass storage devices like hard disk drives or optical discs , but is usually volatile , meaning that it does not retain its contents (instructions or data) in the absence of power, and is much more expensive for a given capacity than is most mass storage. A motherboard contains a microprocessor, the CPU supporting circuitry (mostly integrated circuits ) that provide the interface between memory and input/output peripheral circuits, main memory, and facilities for initial setup of the computer immediately after power-on (often called boot firmware or, in IBM PC compatible computers, a BIOS or UEFI ). In many portable and embedded personal computers, the motherboard houses nearly all of the PC’s core components.
A gaming computer is a standard desktop computer that typically has high-performance hardware, such as a more powerful video card , processor and memory, in order to handle the requirements of demanding video games , which are often simply called “PC games”. An artist’s depiction of a 2000s-era personal computer of the desktop style, which includes a metal case with the computing components, a display monitor and a keyboard (mouse not shown). Modern computers based on the von Neumann architecture often have machine code in the form of an imperative programming language In practical terms, a computer program may be just a few instructions or extend to many millions of instructions, as do the programs for word processors and web browsers for example.
Since modern computers typically execute instructions several orders of magnitude faster than human perception, it may appear that many programs are running at the same time even though only one is ever executing in any given instant. 62 Devices that provide input or output to the computer are called peripherals 63 On a typical personal computer, peripherals include input devices like the keyboard and mouse , and output devices such as the display and printer Hard disk drives , floppy disk drives and optical disc drives serve as both input and output devices. The input of programs and data was to be provided to the machine via punched cards , a method being used at the time to direct mechanical looms such as the Jacquard loom For output, the machine would have a printer, a curve plotter and a bell.
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. SIMATIC PC-based products are developed and manufactured for industrial use.
