Design and analysis of Notebook interface

Notebook interface carrying the performance of the expansion of the notebook, with the hardware and shape changes, the interface part of the layout and design changes, this article will be the current popular interface notebook, to resolve the role and significance of these interfaces, to help consumers use them correctly.

With the shape and use of notebook changes, the layout of the reasonable also become a notebook interface design a major focus, in order to pursue a thin and compact degree, individual products will appear interface conflicting problems, the appearance of this embarrassing design undoubtedly to the user brought a lot of trouble.

Notebook interface models are numerous, this article will be from the USB interface, video interface, other interfaces and expansion dock four aspects to resolve their use and function, each notebook has its own unique interface equipped, the following author will analyze the different interface with the use of the impact.

Name: RJ45 interface

Features: cable interface, lightweight and more use of the card buckle design.

RJ45 interface and USB card

RJ45 network interface is a commonly used network interface, the traditional notebook most of the combination of wireless network card and wired network card, because of the unified design of network cable interface, making many frivolous this use of the open cover of the network interface design, in reducing thickness while playing a fixed network cable role, And the pursuit of the ultimate thickness of the notebook will be a USB add-in card to achieve a bit of functionality.

Name: Audio interface

Features: external headset and microphone, high-end with multichannel.

Notebook audio output and USB sound card

Audio interface is more common is the microphone and headset interface, microphone and headset All-in-one interface is also the most used in notebooks, notebook products after a long period of development, this kind of interface is not much change, because the internal board of the notebook in performance effect is not too able to meet the needs of enthusiasts, USB independent sound card is also a good choice for them.

Name: SD card Reader

Features: Digital equipment for data transmission.

Multi-function Card reader

With the popularization of digital products, a variety of memory cards have been very popular, card readers are more and more appear in the notebook, in the design, the reader is mostly designed to pop-up, although compared to other interfaces is not very functional, but for the user often mobile storage photos is quite real.

Name: Expand Dock Interface

Features: multiple interfaces and power supply can be extended.

Laptop Docking Dock Interface

In many high-end business positioning notebook, are equipped with docking interface, the expansion of the docking station to meet the needs of more users, many docking station also has the function of charging, put it into the office can make your notebook avatar as a workstation.

Name: ExpressCard interface

Features: Can be external independent graphics and other equipment.

ExpressCard interface and discrete graphics combination

ExpressCard is not a new technology interface, now very few laptops use this interface, the beginning of this interface in both desktop and notebook devices, its use is to replace the popular PC card, with hot plug technology and no bridge chip advantages, The more fresh play is to use its independent graphics connected to the display to enhance the performance of large notebook graphics, which is not what other interfaces can do.

Notebook interface part of the development and popularity can not be said to be completely according to the change of time to explain, an interface is the development of whether it is popular, at first and USB, 1394 and E-sata can be carried out data transmission, now only the former retained and be popular, After the development of its speed also has a new version to be promoted.

Notebook interface carrying the task of expanding the notebook, for the diverse needs of different consumption, rich interface to users more free collocation and custom space, similar to ExpressCard this kind of although has faded out of sight of the interface, but for the player has great significance.

The layout and design of the Notebook interface is also a place to show the designer's skill, the number and location of the interface need to be carefully studied and designed to achieve satisfactory results, when first-hand to get a notebook product may be difficult to see the interface design, after a period of time to find a good design is how wonderful, Compared with the changes in performance and shape, the author is more sympathetic to this humanized design.
