The operating system strives to make all accesses appear the same. Management for peripheral devices is bound into two classes of operating systems service routines: I/O and device managers. The user should not have to know what type of device or where the device is located to access data or service software. The control is to make access device independent. Management should remove all physical dependencies from users' access requirements and replace these with logical mechanisms that are already common in programming environments. The goal of peripheral device management services is to make access clear, clean, and transparent to users. Input/output and peripheral device management services were created to remove the physical details of use from user processes and to provide for more seamless and fair management of the resources. Michel, in Computer Systems Performance Evaluation and Prediction, 2003 Peripheral device management Similarly, webcams and monitors are integrated into most laptops, although it’s still possible to connect the computer to a larger monitor or higher resolution webcam.Paul J. For example, webcam, speakers and microphones are integrated inside most smartphones, although the latter cannot be considered a peripheral since it’s a core function of any phone. Today, many peripherals are built-in inside smaller computer devices such as tablets, laptops and smartphones. Internal storage devices such as hard disks are usually connected with a SATA cable, while display port and HDMI are the most popular connections for displays and monitors. Today, the most common connection for external peripherals is the USB connection, both because most computers have several ports available, and because of the simplicity of the plug-and-play feature. Storage peripherals are used to store and record data, and include internal and external hard drives, CD-ROM and DVD drives, and flash memory drives.ĭepending on whether the peripheral is located inside or outside the computer system case, it can be further classified as an internal or external peripheral device.Īn external peripheral can be connected via many different types of cables and connections. Some devices can provide both input and output signals, such as network interfaces, modems, routers, and webcams. Other output peripherals include speakers, 3D printers, and projectors. For example, a monitor or display screen will show the operating system’s desktop, while a laser printer will translate information saved in a word file into printed material. Output peripherals translate digital signals into information that can be interpreted or utilized by the end user. Other input peripherals include joysticks, microphones, webcams, optical scanners, etc. For example, a keyboard will convert keystroke into characters that appear on the computer’s display, while a monitor will transform hand movements into movements of a cursor that can be used to interact with the operating system’s programs. Input devices convert incoming instructions or actions from the user into viable information that can be interpreted by the computer. There are several types of peripherals, although they’re commonly divided into three broad categories: input, output, and storage devices. Peripheral devices include the following:
What does bluetooth peripheral device mean serial#
Peripheral devices connect with a computer through several I/O interfaces, such as communications (COM), Universal Serial Bus (USB) and serial ports such as serial advanced technology attachment (SATA) ones. A peripheral device provides input/output (I/O) functions for a computer and serves as an auxiliary computer device without computing-intensive functionality.
