Answer: The daguerreotype was a unique image, not capable of making multiple copies. then dried, placed under a negative, and exposed to light, producing a photographic print. dyeline process used today.
Explanation:
JPEG is a file format for an image that will be compressed. Since it compressed the file size will be much smaller. That makes JPEG is one of the most used file types for images and was a default format for many application. But the drawback of compressing an image is that a portion of the data will lose and will cause the image quality dropped or produce a noise.
Answer:
(B) It allows an attacker to redirect targets to malicious webserver.
(D) It affects any clients querying the poisoned DNS server.
Explanation:
DNS cache poisoning is a serious type of attack that is designed to exploit the vulnerabilities inherent in a Domain Name Server (DNS) where a user is redirected from a real server to a fake one. It is also called DNS spoofing.
Normally, when your browser tries to visits a website through a given domain name, it goes through the DNS server. A DNS server maintains a list of domain names and their equivalent Internet Protocol addresses. This server (DNS) then responds to the request with one or more IP addresses for the browser to reach the website through the domain name.
The computer browser then get to the intended website through the IP address.
Now, if the DNS cache is poisoned, then it has a wrong entry for IP addresses. This might be via hacking or a physical access to the DNS server to modify the stored information on it. Therefore, rather than responding with the real IP address, the DNS replies with a wrong IP address which then redirects the user to an unreal website.
Although they might not be able to control your computer remotely as long as you are not trying to visit a web page via the poisoned information, there are other dangers attached to this type of attack.
Once the DNS server has been poisoned, any client trying to query the server will also be affected since there is no direct way of knowing if the information received from the server is actually correct.
Answer:
Step 1 : Start
Step2 : Input first number, num1
Step3 : Input second number, num2
Step4 : product - - > num1 * num2 (product of num1 and num2)
Step5 : Input product, myanswer
Step6 : comparison - - - > correct or incorrect based on myanswer and product
Step6: print(comparison)
Step7: End
Explanation:
Algorithm is a sequence of instructions a computer is expected to follow to solve a particular problem.
Required :
Two inputs ; num1 and num2
Expected output
Algorithm :
Step 1 : Start
Step2 : Input first number, num1
Step3 : Input second number, num2
Step4 : product - - > num1 * num2 (product of num1 and num2)
Step5 : Input product, myanswer
Step6 : comparison - - - > correct or incorrect based on myanswer and product
Step6: print(comparison)
Step7: End
The two numbers to multiply are entered ; the product is calculated by the program ; the the user inputs his or her own expecteted product ;
Both are compared and the output of the comparison is displayed (either correct oe incorrect)
Answer:
<u><em>Input Bindings</em></u> is the term that is used for actions carried out on inputs in automation process.
Explanation:
In Automation process different operation or tasks had been performed such as output, input, internal actions. These are known as action bindings.
At input terminal the actions that are being carried out are called Input bindings. A command is comes from control pin and data is comes from input pin. This input and control signal combines together and perform the action that is required by machine or device.
<em>This is the reason these actions performed at input device is called Input Binding.</em>
