- (b) Figure 1, shows an ARM assembly program, which finds the most positive and negative values in a list of 16-bit (half-word) value in data memory (TABLE). The values are in two's complement representations. By examining the program, answer the following questions: (i) Find the errors in the program and make necessary corrections. Do not insert any additional line in the program. (ii) How many bytes does 'TABLE' occupy? (iii) What are the values loaded in the register R2 and R4? (iv) Determine the values of the flags N, Z, C and V. (v) Modify the program such that the numbers in 'TABLE' are represented in 'word' length.arrow_forwardHow are overlapping limitations and disjoint restrictions different from one another?arrow_forwardIt is critical to be able to rapidly determine whether a block is present in the buffer and, if so, where it is located inside the buffer. Given the vast amount of database buffers, what (in-memory) data structure would you employ for this task?arrow_forward
- In a database please help with the following: Explain the access speed required, and how your design will permit this. How often will the database be accessed? How much data will need to be stored or retrieved? What kind of response time will be necessary?arrow_forwardRapidly determining if a block is present in the buffer and, if so, where in the buffer it may be found is essential. What (in-memory) data structure would you suggest for this application given that database buffer sizes are rather large?arrow_forwardIn applications where processing of data records is one after another, suitable processing type should be Sequential access device why?arrow_forward
- How are logical and physical file descriptions different?arrow_forwardExplain the concept of data fragmentation in a distributed database. What are the various fragmentation techniques, and when would you use each one?arrow_forwardHow do datatype storage considerations differ between storing data in serialized form (like JSON) vs. normalized relational columns?arrow_forward
- In data structures and algorithms,which operations combine record into different sorted files into a single sorted file?arrow_forwardAccess path A database table is composed of records and fields hold data. Data is stored in records. A field is a part of a record and contains a single piece of data for the subject of the record.
