Answer:
1. Processor communication -- this involves the following tasks:
a. exchange of data between processor and I/O module
b. command decoding - I/O module accepts commands sent from the processor. E.g., the I/O module for a disk drive may accept the following commands from the processor: READ SECTOR, WRITE SECTOR, SEEK track, etc.
c. status reporting – The device must be able to report its status to the processor, e.g., disk drive busy, ready etc. Status reporting may also involve reporting various errors.
d. Address recognition – Each I/O device has a unique address and the I/O module must recognize this address.
2. Device communication – The I/O module must be able to perform device communication such as status reporting.
3. Control & timing – The I/O module must be able to co-ordinate the flow of data between the internal resources (such as processor, memory) and external devices.
4. Data buffering – This is necessary as there is a speed mismatch between speed of data transfer between processor and memory and external devices. Data coming from the main memory are sent to an I/O module in a rapid burst. The data is buffered in the I/O module and then sent to the peripheral device at its rate.
5. Error detection – The I/O module must also be able to detect errors and report them to the processor. These errors may be mechanical errors (such as paper jam in a printer), or changes in the bit pattern of transmitted data. A common way of detecting such errors is by using parity bits.
Which of the following is the primary difference between analog and digital communication?
Im marking Brainliest
electric cables vs. fiber cables
electric pulses vs. electronic devices
radio signal vs. microwave signal
radio signal vs. radio frequency
Answer:
Radio signal vs. microwave signal.
Explanation:
it's the suitable but again it's a weak answer to compare analog from digital signals
Answer:
Electric pulses vs. electronic devices
Explanation:
edg2021
direct quote from AV notes: "Analog technology transmits information using electric pulses. The human voice is the best example of analog communication. As the telephone was the major communication channel in the past, analog communication was common and the only type used.
Today, we depend on digital communication. Digital technology breaks down information into numerical bits and transmits the bits to digital receivers that decode the bits and recompose the original information. "
You are suddenly given a very large (1000 ) number of old desktop computers with old CRT monitors. What could you do with them
Answer:
I would fix them if they were broken, make good use of them and give them out to other people as marketing or sell them.
Explanation:
Write a program that takes a String containing a text using the method signature
String useProperGrammar(String text)
Your method should replace the word ‘2’ with ‘to’ and return the updated text.
For example,
useProperGrammar("can you go 2 the store?")
should return
"can you go to the store?"
This method should also print out the number of grammatical errors that were fixed.
For example, for useProperGrammar("back 2 back 2 back"), the method would also print:
Fixed 2 grammatical errors:
In the main method, ask the user to input a String, and print the results of useProperGrammar using the user input.
import java.util.*;
public class MyClass {
public static String useProperGrammar(String message){
String newMessage = "";
int count = 0;
for (int i = 0; i < message.length(); i++){
if(message.charAt(i) == '2'){
newMessage = newMessage + "to";
count ++;
}
else{
newMessage = newMessage + message.charAt(i);
}
}
System.out.println("Fixed "+count+" grammatical error(s):");
return newMessage;
}
public static void main(String args[]) {
Scanner scan = new Scanner(System.in);
System.out.println("Enter a string: ");
String text = scan.nextLine();
System.out.println(useProperGrammar(text));
}
}

3. .
4. Can't be done with only HTML5, need help of Javascript or something else.
Answer:
The answer is "Option 2".
Explanation:
In HTML5, text inputs use an autofocus attribute, which, when the page is loaded, uses a template to concentrate primarily on text fields. This attribute is a Boolean property that represents the HTML autofocus attribute, showing if the related <select> element will receive an output focus whenever the page loads if it is overruled by the user. An only form-associated entity can have this property specified in a text.

Imagine that you are in the market for a digital camera. Would it be better for you to purchase a high-quality digital camera or a mobile camera? Explain your answer by providing three reasons why your choice suits your needs.
Answer:
I would purchase a high-quality digital camera
Explanation:
As a blogger, I most times take pictures that should be of high quality to capture the interest of readers. So, if I am in the market to purchase a camera, I would go for a camera that is of high quality. Even though a mobile camera would be less expensive, a high-quality digital camera has features that can be manipulated to get a quality photo that would also last.
The light sensitivity as seen in the ISO, the shutter speed, megapixels, and view-finder are some features I would look out for in a high-quality digital camera.

Divide a network 10.10.0.0 with subnet mask 255.255.0.0 into 62 subnets.
10.10.0.0
0000 1010. 0000 1010 . 0000 0000 . 0000 0000
255.255.0.0
1111 1111. 1111 1111 . 0000 0000 . 0000 0000
Required:
a. How many bits do we need to borrow from the host portion?
b. List the lowest and the highest IP address of the first usable subnet.
c. How many usable hosts are there in total before and after subnetting?
Answer:
A. 6 bits
B. lowest IP address is 10.10.0.1 and the highest IP address is 10.10.3.254
C. total number of usable hosts before subnetting = 65534
total number of usable hosts after subnetting = 65408
Explanation:
The IP address 10.10.0.0 with the subnet mask 255.255.0.0 is a class B address with 16 bits of the network address portion and 16 bits of the host portion.
To subnet the address to use 62 subnets (and to reduce the host IP address wasted) 6 bits are borrowed from the host portion of the address to give 2^6 = 64 subnets with two usable host addresses.
The first network address is 10.10.0.0 and the first usable host address of the subnet is 10.10.0.1 making it the lowest address, while the broadcast address is 10.10.3.255 and the address before it becomes the higher address in the network which is 10.10.3.254
The number of usable host of the network before subnetting is 2^16 -2 = 65534, while after subnetting is (2^(16-6) - 2) x 64 = 65408.

What is computer virus?
Answer:
A piece of code which is capable of copying itself and typically has a detrimental effect, such as corrupting the system or destroying data.
Explanation:
A computer virus is a type of computer program that, when executed, replicates itself by modifying other computer programs and inserting its own code. When this replication succeeds, the affected areas are then said to be "infected" with a computer virus.
Simply, a computer virus is a harmful multiplying code that harms your computer and makes it slower, harder to use, and more vulnerable to other harmful unsafe software, apps, downloads and more.
How to get it?
You can get computer viruses just from going to unsafe websites downloading harmful files downloading harmful images downloading harmful videos clicking unsafe advertisementsand thats just a couple of examples, there's many many more but you get the idea.
Something that really sucks about computer viruses is that its hard to tell if something online is dangerous or not.
That's why people make specific softwares to protect your computer but even those can be unsafe or people could be trying to trick you.
Sometimes the computer will already have some sort of app or software to protect it from these harmful files, but make sure to pay attention when your on websites and check the urls and make sure it doesn't say anything along the lines of "unsafe" if it says that just simply exit the website and dont do anything further.
If your experiencing slowness, files you don't remember saving on your computer or extra files and apps that dont seem to belong, im sure there are places you can call online or in your local area to help with these issues.
Hope this helped!!

which data representation system is based on the digits 0-9 and is mostly easily interpreted In real wrold situations
Answer:
Hexadecimal data representation system is based on the digits 0-9 and is mostly easily interpreted In real word situations .
Explanation:
Hexadecimal manages sixteen different figures: most often the numbers 0–9 to describe values zero to nine, and (A–F) to describe values ten to fifteen. The modern hexadecimal system was first launched into the domain of computing by IBM in 1963. An older description, with 0-9 and u-z, was practiced in 1956 by the Bendix G-15 computer.
