What are the internal hardware constructs for notebooks?

Notebook computer as an important tool in our daily life, has been familiar, the vast number of computer enthusiasts should have contact with notebooks, it is smaller than the desktop system easy to carry, but also because of its small size, disassembly than the desktop slightly difficult, so the internal "visceral" notebook There is a unique kind of mystery.

Below I will lead you to a simple understanding of the internal secrets of the notebook computer:

Notebook computer Although the appearance and desktop has a very big difference, but the internal structure is virtually the same, are composed of the most important computer components, notebook computer is basically divided into two main parts: one is the most intuitive notebook computer display to our device that is the display, The display screen is the output device that shows the computer is the most direct tool that we communicate with computing. The second is a part of the complex components of the output device, which is the most complex notebook computer, including the most parts, which include floppy drive, hard drive, optical drive, CPU, memory, motherboard, battery, graphics and so on. Therefore, although the same type of component, the volume is much smaller than the desktop computer, in the framework of the design process is also more sophisticated, the function is no less than the current notebook computer with a full built-in way, hard disk, memory, batteries, graphics, optical drive, etc. to interface with the main body, so the replacement is more convenient.

　　The following focuses on the second part of the key components:

(1) Cpu

The CPU (cpu,central processing unit) is an oversized integrated circuit that is the computing core (core) and control core of a computer. Mainly includes the operator (Alu,arithmetic Logic unit) and the high-speed buffer (cache) and the implementation of the connection between them (data), control and state of the bus (buses). It is referred to as the five core components of an electronic computer with internal storage (memory) and input/output I/O devices.

(2) Motherboard

The motherboard is also called the host Board (mainboard), the system board (Systemboard) or the motherboard (motherboard), which is installed inside the chassis and is one of the most basic and important components of the microcomputer. The motherboard is generally a rectangular circuit board, which has installed the main circuit system composing the computer, the general has the BIOS chip, I/O control chip, keyboard and Panel control switch interface, LED plug-in, expansion slot, motherboard and card DC power supply connectors and other components. The motherboard uses an open architecture. Most of the motherboard has 6-15 expansion slots, which are plugged into the control card (adapter) of the PC peripherals. By replacing these cards, the corresponding subsystems of the microcomputer can be upgraded locally, so that the manufacturers and users have more flexibility in configuring the models. In a word, the motherboard plays an important role in the whole microcomputer system. It can be said that the type and grade of the motherboard determines the type and grade of the whole crisis system. The performance of the motherboard affects the performance of the whole microcomputer system.

(3) Video card

The full name display interface card, also known as the display adapter (video adapter) or the monitor configuration card, is one of the most basic configurations of the computer card,graphics. The purpose of the graphics card is to transform the display information required by the computer system, to provide data signals to the monitor, to control the correct display of the display, to connect the monitor and the personal computer, and to be one of the important equipment of "man-machine conversation". Graphics card as a computer host in an important part of the output display graphics task, for the professional graphic design of the person who is very important. Civil and military graphics chip suppliers mainly include AMD (Ultra Micro Semiconductor) and Nvidia (NVIDIA) 2. Now the TOP500 computer contains the core of the graphics card computing. In scientific calculations, the video card is called the Display accelerator card.

(4) Memory and hard disk

Notebook interior also contains memory and hard disk hardware, where memory is connected to the CPU and other hardware bridge, determines a certain notebook performance, the current notebook standard memory has reached 4GB.

The hard drive is the notebook data storage center, like the operating system, all kinds of files are stored in the hard disk, the hard disk is divided into SSD and HDD traditional mechanical hard disk, SSD hard disk read faster than mechanical hard disk, so with SSD notebook, with a better speed experience, mainly in the realization of fast switching machine , open a large application faster and so on. and mechanical hard disk is mainly large capacity, affordable.

(5) Floppy drive floppy disk machine (already obsolete)

Floppy disk drive pinyin Ruǎnpán qūdòngqì; The floppy disk drive is what we normally call the floppy drive, the English name is called "Floppy disk Drive", which is a device that reads 3.5-inch or 5.25-inch floppy disks. The most commonly used today is a 3.5-inch floppy drive, which can be read and written to 1.44MB 3.5-inch floppy disks with a 5.25-inch diskette that has been eliminated and rarely seen. Floppy drive divided into built-in and external two kinds. Built-in soft drive with a dedicated FDD interface, the external floppy disk is generally used for notebook computers, using USB interface. Floppy drive has many disadvantages, with the development of computer, these shortcomings are gradually obvious: the capacity is too small, read and write speed is slow, floppy disk life and reliability is poor, data is easy to lose, so the current floppy drive has been replaced by other devices trend. At present, the newly-built computers are no longer installed with floppy drives, and individual installed users are no longer installed However, the floppy drive is still in use by the tax controller because of its low cost.

The above for you to introduce some of the internal existence of the notebook computer Some of the more important places, not mentioned parts are also indispensable, only the combination of all parts can make the notebook computer normal work. I do not know through the introduction of the notebook computer has a preliminary understanding of the inside?
