Answer:
It can do all the functions at a speedy rate and also helps us to search and progress in our homes and businesses. A computer can therefore be called a calculator with a twist for not only does it perform fast calculations, but it also has other special characteristics.
Explanation:
hope it helps you
Answer:
Explanation: search engine uses system algorithm to search out items or information as required by the user. Example is google, chrome.
Data base are archives where information could be retrieve. Its contain information such as publications, abstract,journals.
Search engine provides wide range of information depending on you request while database are mostly for academics related materials.
Data base- A good place to generate this information is library, archivals while journal, publiications are kept while search engine can be used anywhere you have an internet facilities.
In a data base, information is searched in an organized way. The collections are already well arranged in different cubicle search engine provides wide range of information not organized.
Data base may contain more complex information not easily understood, search engine provides more elaborate answers.
Similarity of the two is that they both provide information.
They are both reliable.
School library is an example of where journals and publication are kept and can be retrived.
Regulatory or informational markers are utilized to inform you with respect to circumstances, threats, or headings. They may show reefs, swim territories, speed zones, and so forth. They can be effectively distinguished by the orange groups on the top and base of each float.
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
Answer: c) a program.
Explanation:
A computer, is a hardware device, that differs from those with dedicated hardware (like a TV set, a radio, or an old phone) , in that it can be used for different purposes, due to it's a programmable device.
The way in which the computer is instructed to do anything, is by means of a set of instructions to be read and executed sequentially, which is called a program.
The set of the different programs stored in the computer is which is known as the computer software.
