1) Input devices are any devices that input information to the computer - Examples include your keyboard, mouse, microphone, ect.
2) Output devices are any devices that output information from the computer. - Examples include your monitor, printer, headset/speakers, ect.
3) Processing devices are devices that take the information and process it. The most obvious example of this is the Central Processing Unit (CPU) on your computer.
Answer:
Check the explanation
Explanation:
Going by the question above,there are 2 routers in a sequence amid Host A and Host B and using store-and-forward routing.
So that time would conprise of both propagation delay and transmission time
Propagation delay is nothing but the time taken for traveling.
Transmission delay is the amount of delay time from the beginning to end of transmission)
Now,
Propagation delay = distance traveled / speed of propagation
= 161200 / 2.7 *108 = 59703703.70 * 10-8 mili sec
Transmission delay:
= packet size / bandwidth
= 4 / (9.1 * 1024) = 4.2925 * 10-1 mili sec
Let us assume routers have zero (0) processing time
total time = Transmission delay by host A + Transmssion delay by router1 + Transmssion delay by router2 + propagation time
= 3 * ( 4.2925 * 10-1 ) + (59703703.70 * 10-8)
= 1.28775 + 0.5970370370 ms
= 1.884787 ms

Factors Influencing Unequal Internet Access:
1. Age: Children under 10 and adults over 60 do not enjoy the same level of access to the internet. For children 10, their parents restrict their use of the internet. Most adults over 60 lack the interest and competence to utilize access to the internet.
2. Sex: Men usually enjoy better access to the internet than women. While men explore many sources of internet information, women usually restrict themselves to social media, which is usually their favorites, giving the high-level chatting that is involved in social media.
3. Nationality: Access to the internet is not available equally in all the nations of the world. In communist China, there are government-mandated restrictions placed on citizens. In some sub-Saharan African countries, access to the internet is a luxury that many cannot afford and it is not easily available due to lack of basic internet infrastructure.
4. Education is another factor that influences access to the internet. The level of education dictates whether somebody has access or not. Many illiterate men and women who do not value the internet. What you do not value, you do not use. What you do not use is not accessible to you.
5. Income: This is another important factor that influences access to the internet. In some countries, the availability of high-speed network remains unaffordable to the majority of the population. They only have telephone networks to use their internet access, due to the high cost of high-speed digital satellite-based networks. Many people can only access the internet on public WiFis.
Explanation:
According to wikipedia.com, "Internet access is the ability of individuals and organizations to connect to the Internet using computer terminals, computers, and other devices; and to access services such as email and the World Wide Web."
Answer:
Jacob Gardner - Lucas Robinson - Caden Boothe - Michael Armstrong
Explanation:
According to clue 4, Lucas's house is not the first, and he has a house on his right, so it can only be house 2 or house 3. Therefore, Caden's house (which is on the right right of Lucas's), it can only be house 3 or house 4.
In turn, track 1 says that Michael's house is not next to Lucas's, so it can be 1 (if Lucas's house is 3) or 4 (if Lucas's house is in 2).
Track 2 says that there is a house before Michael's, which eliminates the possibility that Michael's house is number 1 (there would be no previous house). Thus, in addition, Lucas's house turns out to be 2 (Michael's house is not next door) and Caden's is 3, while Jacon's is house 1.
Jacob - Lucas - Caden - Michael
In turn, regarding surnames, clue 2 says that Robinson's house is after Gardner's and before Michael's. Thus, Robinson can be the last name of Jacob or Lucas, and Gardner that of Lucas or Caden. Now, since Boothe's house is just before Armstrong's, the order would be as follows:
Jacob Gardner - Lucas Robinson - Caden Boothe - Michael Armstrong
Answer:
D. int* ptr;
Explanation:
int *ptr; it is pointer used to hold address of another integer variable.In the options provided we have int ptr that is an integer variable of name ptr.
*int ptr; is wrong this will give error because first we have to write the data type.
int ptr*; is an integer varaible with name ptr*.
int* ptr; is a pointer which can hold the address of another integer varaible.
