Answer:
Because reusing the old passwords possess security threats.
Explanation:
A password can be defined as a string of characters or words or phrases that are used to authenticate the identity of the user. It is also known as passcode and should be kept confidential. A password is used to access constricted systems, applications, etc.
A password or passcode is usually composed of alphabets, numbers, symbols, characters, alphanumeric, or a combination of these.
<u>In the given case, Judy was not able to change her passcode to the previous one because reusing old passwords is prohibited in any sites or systems. A system denies the user to reuse the old passwords for various reasons but most importantly due to security reasons. Though it is said that old passwords can be used after 100 times but seldom someone changes a password that much. All systems care for the security of their users thus they deny reusing old passcodes.</u>
Answer:
Sequential
Explanation:
Based on the information provided within the question it can be said that the search algorithm that is being described in this scenario is a Sequential algorithm. This is because sequential programming focuses on programming (or in this case searching for) a result by doing one step at a time as opposed to various functions running simultaneously.
Answer:
True
Explanation:
<u>Algorithm for push function</u>
The method of placing data on a stack is called a push operation.
It involves these steps −
- Check that the stack is complete.
- If the stack is complete, it will cause an error .
- Increases top to point next empty room if the stack is not complete.
- Adds the data component to the place of the stack where top is pointing.
<u>Algorithm for Insertfirst function</u>
- Create a new Link with provided data.
- Point New Link to old First Link.
- Point First Link to this New Link.
As we can see that in both algorithms ,we are inserting data to a new nodes and incrementing/pointing to a new node for inserting data.Both algorithms uses the same approach.
Answer:
Depends. could be an external opticial drive, a scuzi drive, a real to real tape system, or just a simple electromagnetic hard drive with speeds of 1000 rpm or more
