Computers

What exactly is hardware? The hardware are all solid components of a computer, you can touch and are necessary to the functioning of a computer. All programs are on a hard drive or on the operating system, however, is known as software, because you can not touch this. The most common and most important hardware components of a computer are: the memory (including RAM), and the CD-ROM drive, DVD drive, the Blue-Ray drive, CPU, disk drive, printer, video card, hard disk, main board or motherboard , network card and sound card work. Speakers, monitors, mice and keyboards are also considered hardware. Even a USB memory and an external hard drive count as hardware, because these can be stored externally on the data.

The motherboard is the main hardware of a PC

The motherboard lies the CPU, which the center of a computer (electronic data processing operating system) attachment. The designs will be used by this program. A PC would not work without CPU, since this process the various program commands and forwards them. In addition, the motherboard contains the connectors for the main courses, video card, network card and sound card. The hard drives, CD / DVD-ROM drives, Blu-Ray drives, floppy drives, printers, mice and keyboards are also connected to the motherboard. The task of a main memory, it is the ability to quickly call up information that was previously handled or opened (for example, previously edited texts), but only as long as the current flow exists. When you turn off or restart the operating system are the recently lost on the information stored in main memory as well. A video shows the program designs, image files, text files, video files, etc. on the monitor. A network interface card makes the Internet possible, but also the exchange of files in a network, such as in a school or company. The sound card processes the sounds of an application (music, video, file, etc.) and gives them through the speakers again as sound. A hard disk is the most widely used storage medium, as this has much higher storage capacities than on disks, CDs, DVDs, Blu-Ray discs and USB memory. The files will be here quickly and permanently stored. These data are not lost when you switch off the electricity, as in the main memory. CD-ROM, DVD-ROM and Blu-Ray drives keys with vice ray CD / DVD-ROM, Blu-Ray discs and show where the data contained on a PC, DVD or Blu-Ray player. Using CD / DVD / Blue-Ray burner is possible to save data to a CD / DVD-ROM / Blue-Ray disc. These files can then present to other PCs, if they have a CD / DVD-ROM / Blue-Ray drive. Important: CD drives can not read DVD-ROMs and Blue-Ray discs! DVD drives can read CDs and DVDs, however, but also no Blue-Ray discs. On CD-RW and DVD-RW discs you can always delete save data, and then re-venues. You can also save data to diskettes. They have not, however, a large storage capacity. A printer is the edited text and image objects are on paper, as previously shown on the PC. A computer mouse and a keyboard are important components of a computer. For without this we could not open or create data, or change it.
