,C954 Information Technology Management - Set 5 - Part 1
Question 1: What is the role of a "page table" in virtual memory?
Caches recent memory accesses
Maps virtual addresses to physical addresses
Stores data from CPU registers
Manages hardware interrupts
Answer: Maps virtual addresses to physical addresses
The page table translates virtual addresses into physical addresses, enabling efficient
use of virtual memory in computing systems.
Question 2: Which operation in floating-point arithmetic can lead to an
underflow error?
Multiplying two large numbers
Dividing a small number by a large number
Adding two negative numbers
Subtracting two large numbers
Answer: Dividing a small number by a large number
Underflow occurs when a floating-point result is too small to represent, often
happening during division when results are near zero.
Question 3: What type of storage device typically consists of rotating magnetic
disks?
SRAM
DRAM
Hard Disk Drive (HDD)
Flash memory
, C954 Information Technology Management - Set 5 - Part 1
Answer: Hard Disk Drive (HDD)
HDDs use spinning magnetic disks to store data, enabling large-capacity, nonvolatile
storage but with slower access times compared to SSDs.
Question 4: In Java, which access modifier restricts method access to classes
within the same package?
Public
Private
Protected
Static
Answer: Protected
The protected modifier restricts method visibility to classes within the same package
or subclasses, limiting access to internal use.
Question 5: Which memory component stores frequently accessed instructions or
data close to the CPU to speed up processing?
Main memory
Hard drive
Cache memory
Virtual memory
Answer: Cache memory
Cache memory holds frequently used data close to the CPU, reducing access times
and improving system performance.
Question 6: What purpose does the "program counter" (PC) serve in a computer
system?
Executes data fetching
