Since the mid-20th Century the electronics industry has enjoyed phenomenal growth
and is now the largest industry in the world. The foundation of the electronics
industry is the semiconductor device. To meet the tremendous demand of this
industry, the semiconductor-device field has also grown rapidly. Coincident with this
growth, the semiconductor-device literature has expanded and diversified.
This chapter aims at providing an overview of products and systems using
batteries. Here, the term product indicates any device – small or large, portable
or not – powered by a battery. The term system indicates a large installation,
such as an energy storage plant to back up an electricity grid, or an extended
Device Block: Khóa USB, ổ cứng, ổ quang bằng mật khẩu
Không chỉ hỗ trợ khóa ổ USB, ổ cứng, ổ quang bằng mật khẩu, Device Block còn có khả năng cấm máy tính khác trong mạng nội bộ truy xuất dữ liệu được chia sẻ từ máy bạn. Khuyếm khuyết của phương pháp khóa cổng USB để ngăn ngừa người lạ sử dụng ổ USB: chủ nhân máy tính cũng “chịu chung cảnh ngộ”. Trong khi đó, Device Block áp dụng phương pháp linh hoạt hơn: yêu cầu mật khẩu để mở ổ USB.

Highly accurate and thoroughly updated, this text has set the standard in electronic devices and circuit theory for over 25 years. Boylestad offers students a complete and comprehensive survey, focusing on all the essentials they will need to succeed on the job. This very readable presentation is supported by strong pedagogy and content that is ideal for new students of this rapidly changing field.
The first electronic device to be introduced is called the diode. It is the simplest ofsemiconductor devices but plays a very vital role in electronic systems, having char-acteristics that closely match those of a simple switch. It will appear in a range of ap-plications, extending from the simple to the very complex.
Optoelectronics - Advanced Materials and Devices is a second edition following the initial Optoelectronics - Materials and Techniques book published in 2011 as part of the InTech collection of international works on optoelectronics. Optoelectronics, as the discipline devoted to the study and application of electronic devices that emit, detect, and otherwise control light, has widely proliferated globally and enabled many of today's modern conveniences.
Tìm kiếm driver qua Device ID
Việc phải cài đặt trình điều khiển (driver) cho các máy tính để bàn, máy tính xách tay là một công việc đòi hỏi phải có chút kĩ năng. Đôi khi bạn làm mất đĩa CD/DVD driver của máy tính và công việc tìm driver trở nên không hề dễ dàng đối với những người “ngoại đạo”. Thực hiện các hướng dẫn sau để tìm driver một cách nhanh chóng. Các bước tiến hành: 1. Vào mục quản lý thiết bị (device manager) bằng cách vào cửa sổ Run, gõ devmgmt.
The importance of mobile systems programming has emerged over the recent years as a new domain in software development. The design of software that runs in a mobile device requires that developers combine the rules applicable in embedded environment; memory-awareness, limited performance, security, and limited resources with features that are needed in workstation environment; modifiability, run-time extensions, and rapid application development.
Programming Mobile Devices is a comprehensive, practical introduction to programming mobile systems.
This book describes the state-of-the-art advancement in the field of organic electroluminescence contributed by many researchers with internationally established expertise in the field. It includes original contributions on the synthesis of suitable organic materials, fabrication of organic light emitting devices (OLEDs) and organic white light emitting devices (WOLEDs), characterization of these devices and some designs for optimal performance.

A diode is a semiconductor device which allows current to flow through it in only one direction. Although a transistor is also a semiconductor device, it does not operate the way a diode does. A diode is specifically made to allow current to flow through it in only one direction.
The field of microelectronics began in 1948 when the first transistor was invented.
This first transistor was a point-contact transistor, which became obsolete in the 1950s
following the development of the bipolar junction transistor (BJT). The first modernday
junction field-effect transistor (JFET) was proposed by Shockley (1952). These two
types of electronic devices are at the heart of all microelectronic components, but it
was the development of integrated circuits (ICs) in 1958 that spawned today's computer
Storage devices hold data, even when the computer is turned off.
The physical material that actually holds data is called a storage medium. The surface of a floppy disk is a storage medium.
The hardware that writes data to or reads data from a storage medium is called a storage device. A floppy disk drive is a storage device.
The two primary storage technologies are magnetic and optical.
The advances of microelectromechanical systems (MEMS) and devices have been instrumental in the demonstration of new devices and applications, and even in the creation of new fields of research and development: bioMEMS, actuators, microfluidic devices, RF and optical MEMS. Experience indicates a need for MEMS book covering these materials as well as the most important process steps in bulk micro-machining and modeling. We are very pleased to present this book that contains 18 chapters, written by the experts in the field of MEMS. ...
