Answer:
Normalization
Explanation:
Converting a poorly-structured table and optimizing its database structure in order to reduce redundancy in relations can be referred to as database normalization. If the data is not redundant means that data inconsistencies and errors like deletion and insertion will get reduced or eliminated significantly.
Answer:
d) Online, real-time systems.
Explanation:
The options are:
a) Batch processing systems.
b) Personal computer systems.
c) Data compression systems.
d) Online, real-time systems.
And the correct option is D. Online, a real-time system. And this is because it is this which is characterized by the data which is assembled from more than one location as it is online, and various clients from various locations enter the data, and it's updated immediately, as it is a real-time system, which is updated in real-time. And hence D. is the correct option. The data compression system takes the data from one location at a time. The batch processing system is made up of different programs for input, output, and process. and hence is different from real-time, which requires continual all the three. And a PC is not made to a specific function, and it does different activities. Hence, its also not the right option here.
No, some motherboards don't have integrated graphics. For such motherboards, a video card is required.
