Complete Question:
Recall that with the CSMA/CD protocol, the adapter waits K. 512 bit times after a collision, where K is drawn randomly. a. For first collision, if K=100, how long does the adapter wait until sensing the channel again for a 1 Mbps broadcast channel? For a 10 Mbps broadcast channel?
Answer:
a) 51.2 msec. b) 5.12 msec
Explanation:
If K=100, the time that the adapter must wait until sensing a channel after detecting a first collision, is given by the following expression:
The bit time, is just the inverse of the channel bandwidh, expressed in bits per second, so for the two instances posed by the question, we have:
a) BW = 1 Mbps = 10⁶ bps
⇒ Tw = 100*512*(1/10⁶) bps = 51.2*10⁻³ sec. = 51.2 msec
b) BW = 10 Mbps = 10⁷ bps
⇒ Tw = 100*512*(1/10⁷) bps = 5.12*10⁻³ sec. = 5.12 msec
Troy should include a short overview of the story that his video will tell and why he wants to tell it (or what the video will be about and why). It should also include the target audience, and where the video will be published.
Answer:
HTML stands for HyperText Markup Language and is the basic structural element that is used to create webpages. HTML is a markup language, which means that it is used to “mark up” the content within a document, in this case a webpage, with structural and semantic information that tells a browser how to display a page. When an HTML document is loaded by a web browser, the browser uses the HTML tags that have marked up the document to render the page’s content.
There are three types of code that make up a basic website page. HTML governs the structural elements, CSS styles those elements, and JavaScript enables dynamic interaction between those elements.
Answer:
The answer is consistency
Explanation:
Information systems deal with the retrieval, storage, manipulation and sharing of data for organisational needs. It is important that there are measures in place that corresponds to data validity standards. The process that ensures that operations meet these standards is known as consistency.
This is very necessary for information systems.
I'd question the wording, However:
Monitor, Output device.
Keyboard, Input device.
Mouse, Input device.
Speakers Output Device.
Microphone, Input device.
Printer, Output device.
Scanner, input device.
Devices do not have to explicitly be one or the other e.g. a printer with a scanner, or headphones with a microphone.
