It can do the operation by using Program and it contains hardware and software.
២.ធាតុផ្សំរបស់កុំព្យួទ័រ Computer hardware is the collection of physical elements that constitute a computer system. Computer hardware refers to the physical parts or components of a computer such as monitor, keyboard, Computer data storage, hard drive disk, mouse, CPU (graphic cards, sound cards, memory, motherboard and chips), etc. all of which are physical objects that you can actually touch. In contrast,software is untouchable. Software exists as ideas, application, concepts, and symbols, but it has no substance. A combination of hardware and software forms a usable computing system.
កុំព្យូទ័រគឺជាអេទ្បិចត្រូនិចម៉ាស៊ីនម្យ៉ាងដែលដំណើរការបានដោយសារការដំឡើង Program ហើយគ្រឿងផ្សំរបស់វាមាន Software និង Hardware។
គ្រឿងរឹង (Hardware)៖ * គឺជា Physical machine ដែលផ្តុំឡើងដោយ Electronic Circuit ជាច្រើន។ * គឺជា ផ្នែក Electronic Circuit មួយដែលផ្តុំឡើងពីគ្រឿងលោហៈធាតុ តូចៗដែត្រូវបានផលិតឡើងជាបន្ទះៗ ហើយមានមុខផ្សេងៗគ្នាទៅតាម ប្រភេទនិមួយៗ។ ឧៈ Mainboard, Power Supply, CPU, VGA, RAM, HDD, …

First Generation Computers (1940s – 1950s)
First electronic computers used vacuum tubes, and they were huge and complex. The first general purpose electronic computer was the ENIAC (Electronic Numerical Integrator And Computer). It was digital, although it didn’t operate with binary code, and was reprogrammable to solve a
