Answer:
40, 5 and 3
See explaination for the details
Explanation:
A)
Consider the data.
Assume D-cache is empty
An integer size =4bytes
The cache block size =4bytes
Therefore, the number of D-cache misses for reading the first 40 integers is,
= (40×4)/4
= 160/4
= 40
b)
Consider the data.
Assume D-cache is empty
An integer size =4bytes
The cache block size =32bytes
Therefore, the number of D-cache misses for reading the first 40 integers is,
= (40×4)/32
= 160/32
= 5
c)
Consider the data.
Assume D-cache is empty
An integer size =4bytes
The cache block size =64bytes
Therefore, the number of D-cache misses for reading the first 40 integers is,
= (40×4)/64
= 160/64
= 3
Answer:
authentication
Explanation:
At the authentication process, there is a way of identifying a user, this is typically done by having the user enter a valid user name and valid password before access is granted. Here at authentication the process is based on each user having a unique set of criteria for gaining access.
The AAA server have to ascertain by comparing a user's authentication credentials with other user credentials stored in a database. In the event the credentials match, the user is granted access to the network. But on the other hand, If the credentials varies, and authentication fails then network access will be denied.
Answer:
1. This is because non-essential parts of the analog data is cut of so as to represent the analog data digitally.
2. This is because it mirrors closely to the original analog material.
3. i. Temperature ii. Speed ii. Distance iv. Electric current
Explanation:
1. How is a digital representation of analog data a form of abstraction?
Digital representation of analog data is a form of abstraction because, since abstraction, which is the removal of non-essential parts of a material so as to reduce complexity, also non-essential parts of the analog data is cut of so as to represent the analog data digitally.
2.Why is the quality of the photo, music, etc better when more samples are taken?
The quality of these items is better because, as more samples are taken, it reduces the error in the sampling and the item(photo, music etc) mirrors closely to the original analog material.
3. What other examples of analog data can you think of?
i. Temperature ii. Speed ii. Distance iv. Electric current
Answer:
Data hierarchy is basically define to the data which is organized in the systematic manner. The main concept of the data hierarchy is to check the basic structure of the data. It basically involve the fields records and files for the data organization.
The following is the list of the computer data hierarchy from nit to address are:
1) Bit: It is the smallest unit of the data.
2) Field: The collection of all the characters in the data is known as field.
3) Record: The collection of the different fields is known as records.
4) File: The collection of various types of records in the database is known as file.
