What compares the energy output of a system with its energy input?
Is it's Energy Efficiency.
What means work output divided by work input?
input force x input distance > output force x output distance -Novanet
What does reducing friction increase?
Efficiency Efficiency
What is product efficiency?
product efficiency with diagrams
What is thermal efficiency?
Thermal efficiency is the efficiency of a heat engine measured by the ratio of the work done by it to the heat supplied to it.
What is the definition of form in database?
it is a process of eliminate data redundancy and improved data integrity, storage efficiency, or scalability.
What is the definition of normal form in database?
it is a process of eliminate data redundancy and improved data integrity, storage efficiency, or scalability.
What is data redundacy?
Data redundancy means storage of data.
What is a back-up in data storage?
A redundancy or duplication of data.
What is the purpose of the raid adapters?
to connect multiple storage devices for redundancy or speed
What is Data redundancy in DBMS?
Data redundancy in DBMS refers to the duplication of data within a database system. This can result in inconsistencies and inefficiencies, as well as consuming more storage space. It is important to minimize data redundancy in order to maintain data integrity and improve performance.
What is redundacy?
Data redundancy means storage of data.
What is redundancy and inconsistency in data base management system?
Redundancy in a database occurs when the same piece of data is unnecessarily stored in multiple places, leading to inefficiency and potential data inconsistencies. Inconsistency arises when different copies of the same data do not match due to errors or failure to update all instances simultaneously, impacting data integrity and reliability. Database management systems aim to reduce redundancy and ensure consistency through normalization and transaction processing techniques.
Redundancy control in databases?
Redundancy control in databases involves minimizing duplicate data storage to improve efficiency and reduce potential inconsistencies. Techniques such as normalization, using primary keys, and enforcing constraints like unique constraints help prevent redundancy by structuring and managing data effectively. Eliminating redundancy can enhance data integrity, improve query performance, and simplify data maintenance in database systems.
Why 4NF is more desirable Normal Form than BCNF?
Because 4nf minimize the redundancy as well as make storage management..
Why would you need two hard drives?
To increase the physical storage capacity of the computer, or to create redundancy in RAID configurations for data protection.
What is a CRC error?
cyclic redundancy check .A cyclic redundancy check (CRC) is an error-detecting code designed to detect accidental changes to raw computer data, and is commonly used in digital networks and storage devices such as hard disk drives.
