Computer hardware – Wikipedia

Computer hardware includes the physical parts of a computer, such as the case,[1] central processing unit (CPU), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard.[2]

By contrast, software is the set of instructions that can be stored and run by hardware. Hardware is so-termed because it is “hard” or rigid with respect to changes, whereas software is “soft” because it is easy to change.

Hardware is typically directed by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system, although other systems exist with only hardware.

Von Neumann architecture scheme

The template for all modern computers is the Von Neumann architecture, detailed in a 1945 paper by Hungarian mathematician John von Neumann. This describes a design architecture for an electronic digital computer with subdivisions of a processing unit consisting of

Computer Hardware

  • Computers have two main parts: hardware and software
  • Like piano (hardware) and music (software)
  • In this section: hardware

The computer is an amazingly useful general-purpose technology, to the point that now cameras, phones, thermostats, and more are all now little computers. This section will introduce major parts and themes of how computer hardware works. “Hardware” refers the physical parts of the computer, and “software” refers to the code that runs on the computer.

Chips and Transistors

  • Transistor – vital electronic building block

    -Transistors are “solid state” – no moving parts

    -One of the most important inventions in history

    -“Switch” that we can turn on/off with an electric signal
  • Silicon chip – fingernail sized piece of silicon
  • Microscopic transistors are etched onto silicon chips
  • Chips can contain billions of transistors
  • Chips are packaged in plastic, with little metal legs
  • e.g. CPU chips, memory chips, flash chips
  • Silicon (metalloid) vs.

Computer Parts, Components & Hardware

Use these individual computer parts to improve the performance of your desktop computer. This variety of parts includes internal cards, such as video, audio, and expansion cards, that instantly update the computer. Many of these parts are easy to install, even with minimal computer experience.

Increased Memory Size
Random access memory, or RAM, ensures your computer runs smoothly even when you have multiple programs, or graphic-intensive programs, running. A new memory card with greater capacity can be easily plugged into your motherboard to improve performance. Both desktop and laptop memory is available.

Faster Processing
High-quality processor brands, such as Intel and AMD, are available to give your computer the power to manage larger amounts of information. Processors with multiple cores are ideal for multitasking, making them a good choice for graphic design, video editing, and gaming computers. Other accessories, such as CPU cooling systems, help keep your processor at a

Computer Components – Hardware, PC Parts

Computer components like the CPU, motherboard, computer case, RAM and drive are the core of a computer. They determine the capabilities and features of a computer, as well as its power and processing speeds. It’s important to choose computer components that can work together to satisfy your needs.

Computer CPU Processors Provide Processing Power

When building a new computer or upgrading an old one, focus on the computer’s Central Processing Unit (CPU) first, as it defines most of the components a computer can use. It will also determine what you can do with the computer. Typical users can skate by with a basic processor for surfing the net and checking email. Gamers will likely want a quad-core processor, though as games advance, six and eight-core processors become more attractive options. The more cores or threads a computer’s CPU processor has, the better performance it will provide, so graphic designers and
