1Which component of the von Neumann CPU architecture is responsible for performing arithmetic operations (such as addition and subtraction) and logical evaluations?
A.Arithmetic Logic Unit (ALU)
B.Control Unit (CU)
C.Program Counter (PC)
D.Memory Data Register (MDR)
Explanation: The Arithmetic Logic Unit (ALU) performs all mathematical calculations (addition, subtraction) and logical comparisons (AND, OR, NOT) within the CPU. The Control Unit manages the fetch-decode-execute cycle and directs data flow, while registers hold temporary data and addresses.
2During the CPU fetch-decode-execute cycle, what is the primary role of the Program Counter (PC)?
A.To store the result of the most recent ALU computation
B.To hold the memory address of the next instruction to be executed
C.To store the current instruction while it is being decoded
D.To hold the data value fetched directly from secondary storage
Explanation: The Program Counter (PC) keeps track of execution by storing the memory address of the next instruction. After an instruction is fetched into the Memory Instruction Register (or Instruction Register), the PC automatically increments to point to the subsequent memory location.
3Why is cache memory positioned between the CPU cores and main RAM in modern computer architecture?
A.Cache memory provides larger storage capacity than secondary magnetic storage at lower cost
B.Cache memory is non-volatile, protecting critical OS files during sudden power losses
C.Cache memory provides extremely fast access times for frequently used instructions, reducing CPU idle time
D.Cache memory converts analog input signals into digital signals for processing
Explanation: Cache memory is static RAM (SRAM) built directly on or near the processor die. Because SRAM operates significantly faster than main RAM (DRAM), storing frequently accessed instructions in cache reduces the time the CPU spends waiting for data retrieval across the system bus.
4Which statement accurately describes a fundamental difference between RAM and ROM?
A.RAM is read-only memory, whereas ROM can be written to and modified continuously
B.RAM is non-volatile primary memory, whereas ROM loses its data when the computer is turned off
C.RAM holds temporary data and running software, whereas ROM contains permanent startup code (BIOS/UEFI)
D.RAM is secondary magnetic storage, whereas ROM is primary optical storage
Explanation: RAM (Random Access Memory) is volatile, read-write memory used by the operating system and applications while the computer is operating. ROM (Read-Only Memory) is non-volatile memory containing permanent boot instructions (such as the BIOS) required to start the computer.
5What technology allows Electrically Erasable Programmable Read-Only Memory (EEPROM) to be updated without physically removing the chip from the circuit board?
A.Exposure to high-intensity ultraviolet (UV) light bulbs through a glass window
B.Application of electric voltage signals to erase and rewrite data blocks electronically
C.Magnetic realignment of iron oxide particles on the surface of the chip
D.Manual mechanical switching of micro-diodes using physical pin tools
Explanation: EEPROM can be erased and rewritten electronically using electric pulses without requiring removal from the motherboard. This enables firmware updates (such as flashing the system BIOS) directly in software. Older EPROM chips required UV light exposure through a quartz window.
6Why do Solid State Drives (SSDs) offer faster data access speeds and greater shock resistance compared to traditional Hard Disk Drives (HDDs)?
A.SSDs contain faster rotating magnetic platters with dual read/write heads
B.SSDs use flash memory chips with no moving mechanical parts, eliminating seek latency
C.SSDs store data using optical laser beams focused on reflective polycarbonate tracks
D.SSDs use high-capacity magnetic tapes that read data continuously in parallel
Explanation: SSDs use non-volatile NAND flash memory chips to store data electronically. Because there are no spinning platters or moving read/write heads (unlike HDDs), SSDs eliminate physical mechanical delay (seek time) and are far less vulnerable to physical shock or drops.
7What enables a standard Blu-ray disc to store significantly more data (up to 25 GB single-layer) than a standard DVD (4.7 GB) of the exact same physical size?
A.Blu-ray discs use magnetic fields instead of optical laser technology
B.Blu-ray uses a shorter wavelength blue-violet laser allowing tighter pit spacing and narrower track pitch
C.Blu-ray discs spin ten times faster than DVDs, creating denser virtual tracks
D.Blu-ray discs compress data using lossy MP3 audio algorithms automatically
Explanation: Blu-ray optical drives use a 405 nm blue-violet laser, which has a shorter wavelength than the 650 nm red laser used in DVDs. The smaller laser spot size allows physical pits and lands to be etched much closer together on the disc surface, increasing data density.
8An enterprise organization requires a secondary storage medium for long-term archiving of multi-terabyte financial backups that must be preserved cheaply for 15 years. Which storage technology is most suitable?
A.Solid State Drives (SSDs)
B.High-speed Dynamic RAM (DRAM)
C.Magnetic Tape Drive Storage
D.USB Flash Memory Thumb Drives
Explanation: Magnetic tape (such as LTO tape) provides the lowest cost per gigabyte, high durability, long shelf-life (30+ years when stored properly), and high storage capacity, making it the industry standard for cold archival backups despite its slow sequential access times.
9How does an RFID (Radio Frequency Identification) system differ from a traditional barcode scanning system in inventory tracking?
A.RFID requires direct line-of-sight visual alignment with every individual tag scanner optical lens
B.RFID tags can be read wirelessly from a distance without line-of-sight and multiple tags can be scanned simultaneously
C.Barcodes can hold megabytes of read-write data, whereas RFID tags only hold 8 bits of static data
D.Barcode readers use radio waves, whereas RFID tags rely on thermal heat sensors
Explanation: RFID uses electromagnetic radio waves to read data stored on microchips embedded in tags. Unlike optical barcode scanners, RFID readers do not require direct line-of-sight and can read dozens of tags concurrently across several meters.
10In an automated greenhouse control system, what is the specific role of an actuator?
A.To measure ambient humidity levels and output an analog voltage signal
B.To convert digital control commands from the microcomputer into physical motion or action (such as opening a valve)
C.To store sensory history data permanently in non-volatile database files
D.To convert optical light into digital binary code for CPU processing
Explanation: An actuator is an output device that converts electrical signals from a computer controller into mechanical motion or physical action, such as opening water valves, turning on cooling fans, or adjusting window vents in an automated system.
