To do this, she needs to show her information in a very efficient way. Because she does have a lot of experience, and wants to show how multi-faceted she is a manager, she opts against the standard objective statement and instead uses a summary statement.
USB was designed to replace the multitude of cables and connectors required to connect peripheral devices to a host computer. The main goal of USB was to make the addition of peripheral devices quick and easy.
All USB devices share some key characteristics to make this possible. All USB devices are self-identifying on the bus. Additionally, some devices can draw power from the USB which eliminates the need for extra power adapters.
To ensure maximum interoperability the USB standard defines all aspects of the USB system from the physical layer mechanical and electrical all the way up to the software layer. Although beyond the scope of this document, details on these specs can be found on the USB-IF website.
A host PC can have multiple host controllers which increases the maximum number of USB devices that can be connected to a single computer. Devices can be connected and disconnected at will. The host PC is responsible for installing and uninstalling drivers for the USB devices on an as-needed basis.
There can also be zero or more USB hubs in the system. A USB hub is special class of device. The hub allows the connection of multiple downstream devices to an upstream host or hub.
In this way, the number of devices that can be physically connected to a computer can be increased. The range of functionality of USB devices is ever increasing. The device can support either one function or many functions. For example a single multi-function printer may present several devices to the host when it is connected via USB.
It can present a printer device, a scanner device, a fax device, etc. All the devices on a single USB must share the bandwidth that is available on the bus. It is possible for a host PC to have multiple buses which would all have their own separate bandwidth.
Most often, the ports on most motherboards are paired, such that each bus has two downstream ports. The USB has a tiered star topology Figure 1.
At the root tier is the USB host. All devices connect to the host either directly or via a hub. Low-speed and high-speed enabled devices will only see traffic at their respective speeds. Full-speed devices can see both their speed and low-speed traffic.
When a host sends a packet, all downstream devices will see that traffic. If the host wishes to communicate with a specific device, it must include the address of the device in the token packet.
Upstream traffic the response from devices are only seen by the host or hubs that are directly on the return path to the host. There are, however, a few caveats when dealing with devices that are of different speeds.
Low-speed and high-speed devices are isolated from traffic at speeds other then their own. They will only see traffic that is at their respective speeds. Referring to Figure 2this means that downstream traffic to device H1 will be seen by device H2 and vice versa.
Also, downstream traffic to device L1 will be seen by L2 and vice versa. However, full-speed devices can see traffic at its own speed, as well as low-speed traffic, using a special signaling mode dubbed low-speed-over-full-speed. This means that downstream traffic to F1 will be seen by F2 and vice versa with standard full-speed signaling, and downstream traffic to either L1 or L2 will also be seen by both F1 and F2 through the special low-speed-over-full-speed signaling.
The added power allows for a broader range of devices to be bus-powered.
Link-level power management allows the host or device to initiate a transition to a lower-level power state. Low-power levels are configurable on the device level and the function level. A device can suspend all or some of this functionality when it is idle, therefore reducing its power consumption.
With Latency Tolerance Messaging, devices can report their latency tolerance to the host, allowing the host system to enter lower power states without negatively affecting the USB devices on the bus.Fulfillment by Amazon (FBA) is a service we offer sellers that lets them store their products in Amazon's fulfillment centers, and we directly pack, ship, and provide customer service for these products.
