what is computer virus
Answer:
A type of malicious code or program written to alter the way a computer operates and is designed to spread from one computer to another.
Once a virus has successfully attached to a program, file, or document, the virus will lie dormant until circumstances cause the computer or device to execute its code. In order for a virus to infect your computer, you have to run the infected program, which in turn causes the virus code to be executed.
Answer:

Suppose you are asked to design a rotating disk where the number of bits per track is constant. You know that the number of bits per track is determined by the circumference of the innermost track, which you can assume is also the circumference of the hole. This, if you make the hole in the center of the disk larger, the number of bits per track increases, but the total number of tracks decreases. If you let r denote the radius of the platter, and x · r the radius of the hole, what value of x maximizes the capacity of the disk?

LAB: Input and formatted output: House real estate summary
Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (currentPrice * 0.051) / 12 (Note: Output directly, do not store in a variable, and end with a newline).
Ex: If the input is:
200000 210000
the output is:
This house is $200000. The change is $-10000 since last month.
The estimated monthly mortgage is $850.0.
Note: Getting the precise spacing, punctuation, and newlines exactly right is a key point of this assignment. Such precision is an important part of programming.
LabProgram.java
1 import java.util.Scanner;
2
3 public class LabProgram {
4 public static void main(String[] args) {
5 Scanner scnr = new Scanner(System.in);
6 int currentPrice;
7 int lastMonthsPrice;
8 currentPrice - scnr.nextInt();
10 last MonthsPrice = scnr.nextInt();
11
12 /* Type your code here. */
13 }
14 ]
15
Answer:
current_price = int(input())
last_months_price = int(input())
change = current_price - last_months_price
mortgage = current_price * 0.051 / 12
print('This house is $', end= '')
print(current_price, end= '. ')
print('The change is $', end= '')
print(change, end= ' ')
print('since last month.')
print('The estimated monthly mortgage is $', end= '')
print(mortgage, end='.\n')
In this exercise, using the knowledge of computational language in python, we have that this code will be written as:
The code is in the attached image.
We can write the python as:
current_price = int(input())
last_months_price = int(input())
change = current_price - last_months_price
mortgage = current_price * 0.051 / 12
print('This house is $', end= '')
print(current_price, end= '. ')
print('The change is $', end= '')
print(change, end= ' ')
print('since last month.')
print('The estimated monthly mortgage is $', end= '')
print(mortgage, end='.\n')

Juan is a network administrator and must set up a VPN for his company's network. To allow safe communication, he should
select Control Panel, then Network Protocols, then Internet
select the radio button, then change the adapter settings protocol
select the Security tab, then PPTP, and then Allow Protocols
select Set Up a Public Connection, then Disable Protocols
Answer:
select Control Panel, then Network Protocols, then Internet
Explanation:
Seeing as Juan is a network admin, he has access to the programs of the computer. Being tasked with setting up a VPN, he must go to the control panel, then network protocols (to see the network rules, per say), then the internet tab to finally set up the VPN.
To allow safe communication, Juan must select control panel then, network protocols, and then internet. Therefore, option A is correct.
What is VPN ?You can interact secretly and securely within your corporation using a virtual private network (VPN), which is an extension of a company's intranet over the preexisting structure of either a public or private network.
The i5/OS operating system is utilised by both businesses, and a VPN connection can give them the protection they require to communicate between their respective networks. Compared to using conventional non-switched lines, creating a VPN is more cost-effective.
To allow a safe communication, the network operator should allow the internet protocol to interpret and which can be activated from the control panel. Hence, option A is correct.

a. Programmed I/O.
b. Direct Memory Access (DMA).
c. Polling.
d. CPU interrupt.
Answer:
B. - Direct Memory Access (DMA)
Explanation:
...
Direct Memory Access (DMA) is the technique to free up the CPU by allowing device controllers to independently transfer data between the device and main memory. Thus, option B is correct.
What is Direct Memory Access?Direct memory access is a computer system feature that allows some hardware subsystems to access main system memory without relying on the central processor unit.
Direct memory access (DMA) is the method of transmitting data without using the CPU. It is frequently used to transport data to and from input/output devices. To manage the transfer, a second DMA controller is necessary.
DMA is a mechanism that allows an input/output (I/O) device to transmit or receive data directly to or from main memory, bypassing the CPU to speed up memory operations. A chip known as a DMA controller manages the process (DMAC).
Therefore, option B is correct.
