Computer hardware and software
A: Hardware
CPU: central processing device is one of the main computer, the main function of computer instructions and data interpretation processing computer software. Programmable computer programming mainly refers to the central processor.
Board: providing mounting position, power, and other computer hardware for other functions of the integrated circuit configuration and the circuit board slot.
Graphics: basic personal computer is one of the components, the display information is to use the computer system needed to convert driving the display, and to provide progressive or interlaced display signal, the display controls the display of the right, and is connected to a personal computer monitor important components of the motherboard, is one of the important equipment, "man-machine dialogue".
Memory: a computer CPU components addressable via the bus, and read and write operations. Memory on a personal computer history was once the main memory expansion. With the computer hardware and software technology constantly updated requirements, memory has become a read-write memory as a whole. We usually refer to the size of the total capacity, which means the memory of the computer memory (RAM),.
Power: the power supply means is capable of converting electrical energy into other forms of energy provided to the personal computer.
Fan: cpu heat
Hard: storing data, divided into solid-state drive (SSD) (SSD disk, the new hard disk), mechanical hard disk (an HDD), a hybrid hard drive (HHD); SSD using flash memory to store the particles have sata solid, M.2 solid, pci-e solid, and the solid M.2 M.2 and have nvme of the sata m.2. Mechanical magnetic disc drives use to store, 3.5 inch, 2.5 inch, as well as 5400 and 7200. Mixing the mechanical hard disk drive is integrated for a hard disk and a flash memory together.
Monitor: monitor also commonly referred to. The display is part of a computer I / O devices, i.e., input and output devices. It is a constant of the electronic file through the particular transmission device displayed on the screen and then reflected to the display means of the human eye.
Mouse: An input device of the computer, the computer display system is positioned in the vertical and horizontal coordinates indicator mouse named because of the shape (as Hong Kong and mouse). The standard should be called "mouse", the English name "Mouse", use the mouse to make the operation easier and faster computers, instead of a keyboard that complicated instructions.
Keyboard: a command and data input means for operating the apparatus operation, through the system also refers to arrange a function key operation of a machine or device.
II: Software
System Software: Operating System
Software: qq micro-channel
Operating system: management of computer hardware and software resources of a computer program, but also the core and the cornerstone of the computer system. The operating system need to be addressed as priorities memory management and configuration, the system determines supply and demand of resources, the control input device and an output device, the basic operation of the network and management of the transaction file system. Operating system also provides a user interface to let users interact with the system.
Common systems: windows, linux, unix, IBM's OS / 360, OS / 390, Mac OS
