Answer: Column F
Explanation: In Microsoft excel, for the sake of robustness and to aid the effectiveness of updating formulas across cells. The reference of cells are treated as relative which means that when formulas are copied across columns or within rows, they get updated automatically. However, some numbers may be treated as constants such that we do not want them to change or be updated as we move acisss cells. Thus, such numbers are treated Given absolute references, which is made possible by adding a '$' prefix before the colum alphabet or row number or both. in the scenario given above, the row has the $ prefix, hence, it is absolute and will not change but the column alphabet does not and hence, treated as relative.
Cache memory is a high-speed memory that stores the instructions and data that have been frequently accessed. It decreases the time it takes to decode the instructions stored in the instruction pipeline.
A. It decreases the time it takes to decode instructions stored in the instruction pipeline.
<u>Explanation:</u>
Whenever an instruction is invoked or some data is accessed, the CPU looks for it in the cache memory before accessing the main memory.
If the content is found in the cache memory, it accessed from there and then and hence the access time and decode time is reduced as there were no main memory lockups.
Answer:
Explanation:
<u>Transient Objects:</u> Transient Objects are that has been just instantiated. Transient objects don't have representation and identifier value in the databases. The transient objects will be destroyed by the garbage collector if they don't have any use and reference in the database.
<u>Persistent Objects:</u> Persistent Objects have representation in databases and identifiers. These objects are saved in the databases. Persistent objects are synchronized with that of the database.
The persistence in Object Oriented Databases is handled by creating Persistent Objects and Transient Objects. As stated above the persistent objects have representations in the databases.
