C952 Computer Architecture - Set 3 - Part 1

Correct Answer: Embedded computer

Embedded computers are designed for specific applications within other devices, like cars or appliances, providing dedicated functionality.

Correct Answer: Throughput

Throughput measures how many tasks are completed within a specific timeframe, indicating system efficiency.

Correct Answer: Public

The public keyword makes a method accessible from any class, ensuring broad visibility across packages.

Correct Answer: Error detection code

Error detection codes identify errors in data without correcting them, flagging the need for further handling.

Correct Answer: Striping

Striping divides data across multiple disks, enhancing access speed by allowing parallel reads and writes.

Correct Answer: Nonvolatile memory

Nonvolatile memory, such as flash or hard drives, holds data without requiring power, making it suitable for long-term storage.

Correct Answer: Combines program modules into an executable file

A linker combines independently compiled modules and resolves references, creating a complete executable file.

Correct Answer: PC-relative addressing

PC-relative addressing calculates an address by adding an offset to the current value in the Program Counter, useful in branch instructions.

Correct Answer: DRAM

DRAM requires regular refresh cycles to retain data, unlike SRAM, which holds data as long as power is applied.

Correct Answer: Just-In-Time (JIT) compiler

The JIT compiler translates Java bytecode into native machine code at runtime, optimizing performance on the host platform.

Correct Answer: Conducts arithmetic and logical operations

The ALU (Arithmetic Logic Unit) executes arithmetic and logical operations, which are crucial for data processing in the CPU.

Correct Answer: Block

Cache memory organizes data in blocks or lines, representing the smallest unit that can be present or absent from the cache.

Correct Answer: Nonvolatile memory

Nonvolatile memory stores data permanently, making it ideal for firmware that must persist even after power is off.

Correct Answer: Translation Lookaside Buffer (TLB)

The TLB is a specialized cache for address mappings, reducing the need to access the page table frequently.

Correct Answer: Multiple virtual addresses point to the same physical address

Aliasing occurs when different virtual addresses access the same physical memory, often managed carefully to avoid conflicts.

Correct Answer: Recent branch instruction outcomes

A branch prediction buffer keeps track of recent branch results, aiding the CPU in predicting future branch behaviors to optimize performance.

Correct Answer: Pseudoinstruction

Pseudoinstructions are convenient shortcuts for more complex instructions and are often expanded by assemblers.

Correct Answer: Static method

Static methods are associated with the class itself rather than any specific instance, allowing direct access without object instantiation.

Correct Answer: Points to the most recent stack frame

The stack pointer indicates the last allocated address in the stack, essential for function calls and local data storage.

Correct Answer: Basic block

Basic blocks are sequences of instructions without branches, providing a continuous path of execution, aiding code optimization.
