U disk use relevant terminology description

USB requires support from three aspects of host hardware, operating system, and peripherals to work. and USB interface can also be a special USB connecting machine to achieve dual-computer interconnection, and can expand through the hub more interfaces. USB has fast transmission speed, easy to use, support hot plug, flexible connection, independent power supply and other advantages.

Data transfer Rate

The portable storage relies on the USB interface to connect with the system, and its interface speed limits the data transmission rate of the mobile hard disk. The current USB1.1 interface can provide 12Mbps; The USB 2.0 interface provides a 480mbps;ieee1394a interface to provide a 400mbps;ieee1394b rate of data transfer, but in practical applications for some objective reasons (such as the master chip used in storage devices, The production quality of the circuit board is excellent, etc., which slows down the transfer rate in the application.

Storage capacity

Storage capacity is the maximum amount of data that the portable storage product can store and is the most critical parameter of a portable storage product. The capacity of the general portable storage is in megabytes MB, 1GB, 2GB,4GB, 8GB, 16GB and some higher capacity products, but the price is more than the user can accept. where 512MB of portable storage, has been basically eliminated by the market, and 8G, 16G products are the mainstream of the market, prices in the general user can accept the range, but also the manufacturers to launch the most type of product types; 32GB~64GB products, because the price is expensive, the user group is few, the product kind also is few.

Operating system

Refers to the operating system in which a portable storage product works correctly. As a hardware product, you must have good software support and a compatible operating system to play its role. Most Windows operating systems can directly support the flash disk without installing additional drivers, which is the biggest advantage of the flash drive.

Windows XP

Windows XP, or Window XP, is Microsoft's latest version of a Windows operating system. It was released on October 25, 2001, and the original name was Whistler. Microsoft initially released two editions, the home version and the Professional Edition (Professional). The home version of the consumer object is home users, Professional edition in the home version of the new business-oriented design of the network certification, dual processor features. The letter XP represents the "experience" of an English word (experience). Windows XP is a product based on Windows 2000 code and has a new user graphical interface called the Luna, which includes minor modifications. In addition, Windows XP introduces a "People based" user interface that allows the toolbar to access specific details of a task. It includes the simplified user security features of Windows 2000 and consolidates firewalls to ensure that security issues that have plagued Microsoft for a long time.

Windows 7

Windows 7 is an operating system developed by Microsoft Corporation. Windows 7 can be used for home and business work environments, laptops, tablets, multimedia centers, and more. Microsoft October 22, 2009 in the United States, October 23, 2009 in China officially released Windows 7, February 22, 2011 released windows 7 SP1 (build7601.17514.101119-1850). Windows 7 also publishes the server version--windows servers 2008 R2. Windows Server 2008 R2 continues to promote applications in areas such as virtualization, System Management resiliency, network access, and information security, compared with Windows Server 2008, which was released in January 2008, with a number of features that need to match windows 7.

MAC OS

Mac OS is an operating system that Apple has developed to apply to its production of Apple computers. With strong stability and powerful functions, the Apple machine is more used in the field of professional mapping, less home users.

Linux

Linux is a Unix-like system that was first written by Linus Torvolds, a college student at the University of Helsinki in Finland, in 1991. Linux is a free operating system that allows users to get their source code for free and can modify it at will. It is free software under the common license GPL (general public License), as well as several versions, such as Red Hat Linux, Slackware, and domestic Xteam Linux.

Linux has the features and features of many UNIX systems that are compatible with UNIX, but do not have to pay for high UNIX costs. For example, a UNIX programmer can work on a UNIX system in a unit and go home and do the same thing on a Linux system without having to buy Unix again. Knowing that UNIX is priced several times higher than common windows is far more expensive than Linux.

The advantage of Linux is that it is a free operating system that users can get free of charge through the Internet or other channels, and can modify their source code arbitrarily. Under Linux, Run Common DOS and Windows programs through the corresponding simulator. This lays the groundwork for users to move from Windows to Linux. Linux supports multiple users, each user for their own file equipment has its own special rights, to ensure that the user does not affect each other. Multitasking is now the main feature of the computer, Linux allows multiple programs to run simultaneously and independently.
