Answer:
a) Yes
b) Yes
c) Yes
d) No
e) Yes
f) No
Explanation:
a) All single-bit errors are caught by Cyclic Redundancy Check (CRC) and it produces 100 % of error detection.
b) All double-bit errors for any reasonably long message are caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit. It also produces 100 % of error detection.
c) 5 isolated bit errors are not caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit since CRC may not be able to catch all even numbers of isolated bit errors so it is not even.
It produces nearly 100 % of error detection.
d) All even numbers of isolated bit errors may not be caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit. It also produces 100 % of error detection.
e) All burst errors with burst lengths less than or equal to 32 are caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit. It also produces 100 % of error detection.
f) A burst error with burst length greater than 32 may not be caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit.
Cyclic Redundancy Check (CRC) does not detect the length of error burst which is greater than or equal to r bits.
Answer:
1. More access to data
2.convenience
3. Easy creation of BI solutions
4. Report creation
5. Saves time
Explanation:
A data warehouse can be described to be an electronic storage system that contains large amount of facts and information which sources for and also maintains data from different sources; either external or internal.
The most important reason for a data warehouse is for it to store great amounts of data to be used for query and also to be used for analysis.
Why do we use a data warehouse?
1. Users have more access to data due to the integration of various sources of data. It makes use of real time data facts
2. You can conveniently store and also create metadata
3. Business intelligence solutions can easily be created using data warehouses.
4. Users can easily create their own reports
5. Data warehouses makes accessing different data sets faster. It is a time saver as business users are not going to spend time trying to retrieve data from various sources.
A process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer.
The hotbar is what i think it is called but it is basically the bar of stuff at the bottom of the screen on windows computers.
