Answer:
True is the correct answer for the above question.
Explanation:
- When any document file is opened then every point has some particular address. so there is a pointer which states that where the read operation and the write operation is going on.
- When any person writes any program to read a file or write a file then there is a need for some variable that is pointed for the reading and the write operation.
- The document which is used for the write data or read data is also designed and maintained by some software.
- Hence we can say that there are needs of some variable that point the operation of the file and it is also stated from the above question. Hence the above question statement is a true statement.
Answer:
31 bits.
Explanation:
Given, total number of registers = 55
Total instructions = 60
Size of memory = 16 KB
Now, no of registers are 55. We find the next greater or equal power of 2 which is 64 = 26. Hence, 6 bits are required to represent a register operand.
Number of instructions = 60. We find the next greater or equal power of 2 which is 64 = 26. Hence, 6 bits are required to represent a instruction.
Size of memory = 64 KB = 26 * 210 * 23 bits = 219 bits. Hence, 19 bits are required to represent a memory location.
Now, an instruction has 2 parts, opcode and operand. As given there are only two address instructions which are memory operand and register operand.
Hence, total bits would be: 6 bits (opcode) + 6 bits (register operand) + 19 (memory operand) = 31 bits.
