Explanation and Procedure to Speed Up the System Upgrade RAM The reason why people need to upgrade their computer RAm is to make sure that they can get a bigger workplace in which allows the computer to run faster. Check and see how much RAm has been used. In order to check, simply right click the taskbar and choose the Task Manager.
The major goal of USB was to define an external expansion bus to add peripherals to a PC in easy and simple manner. The new external expansion architecture, highlights, 1.
PC host controller hardware and software 2. Robust connectors and cable assemblies 3. Peripheral friendly master-slave protocols 4. Expandable through multi-port hubs.
USB offers users simple connectivity. It eliminates the mix of different connectors for different devices like printers, keyboards, mice, and other peripherals. That means USB-bus allows many peripherals to be connected using a single standardized interface socket.
It supports all kinds of data, from slow mouse inputs to digitized audio and compressed video.
USB also allows hot swapping. The "hot-swapping" means that the devices can be plugged and unplugged without rebooting the computer or turning off the device. That means, when plugged in, everything configures automatically. So the user needs not worry about terminations, terms such as IRQs and port addresses, or rebooting the computer.
Once the user is finished, they can simply unplug the cable out, the host will detect its absence and automatically unload the driver.
This makes the USB a plug-and-play interface between a computer and add-on devices. USB is now the most used interface to connect devices like mouse, keyboards, PDAs, game-pads and joysticks, scanners, digital cameras, printers, personal media players, and flash drives to personal computers.
Generally speaking, USB is the most successful interconnect in the history of personal computing and has migrated into consumer electronics and mobile products.
USB sends data in serial mode i. The benefits of USB are low cost, expandability, auto-configuration, hot-plugging and outstanding performance. It also provides power to the bus, enabling many peripherals to operate without the added need for an AC power adapter.
Let us now try to understand more about the different versions of the USB. And as we know it was a combined effort of some large players on the market to define a new general device interface for computers.
The data transfer rate of this version can accommodate a wide range of devices, including MPEG video devices, data gloves, and digitizers. USB got integrated into Windows 98 and later versions. Today, most new computers and peripheral devices are equipped with USB. This version is similar to the original release of USB; however, there are minor modifications for the hardware and the specifications.
This standardization of the new device-specification made backward compatibility possible, meaning it is also capable of supporting USB 1.
Supporting three speed modes 1. That's about 40 times as fast! Products using the 3. The technology targets fast PC sync-and-go transfer of applications, to meet the demands of Consumer Electronics and mobile segments focused on high-density digital content and media.
The technology draws from the same architecture of wired USB. In addition, the USB 3.The following learning tools are incorporated in the structure of the course: Discovery question. Scenario.
