Q3Computer · Computer Hardware (Input/Output, Buses & Ports)NVS PGT 2019
Which bus is used to specify memory locations for the data being transferred?
Answer: C) Address bus
In computer systems, the address bus is used to specify memory locations for data being transferred. It is a unidirectional bus that carries address signals from the CPU to memory or I/O devices. When the CPU needs to read or write data from a specific memory location, it sends the address of that location on the address bus. The actual data transfer then occurs on the data bus. The width of the address bus determines the system's memory addressing capability for example, a 32-bit address bus can address up to 4GB of memory. -

Q11Computer · MemoryRRB NTPC (Undergraduate)
A student notices that arithmetic results appear instantly, but loading data from main memory is slower. Which CPU feature primarily reduces this delay by keeping frequently used data close to the processor?
एक विद्यार्थी ने देखा कि गणित के परिणाम शीघ्र दिखाई देते हैं, लेकिन मुख्य मेमोरी से डेटा लोड करने में समय लगता है। कौन-सा CPU फीचर मुख्य रूप से बार-बार उपयोग किए जाने वाले डेटा को प्रोसेसर के पास रखकर इस विलंब को कम करती है?
Answer: A) Cache Memoryकैश मेमोरी
Topic: Computer Organization - Memory Hierarchy
Problem: Arithmetic operations are fast, but fetching data from main memory is slow.
Key Concept:
Cache Memory is a small, high-speed memory located between CPU and main memory.
It stores frequently accessed data and instructions to reduce memory access time.
Other options:
Address Decoder - selects memory locations (not storage)
Instruction Set - defines CPU operations (not storage)
CPU Fan - cooling device (not related to data access)
Answer: Option 1 → Cache Memoryविषय: कंप्यूटर संगठन - मेमोरी पदानुक्रम
समस्या: अंकगणितीय संक्रियाएं तेज हैं, लेकिन मुख्य मेमोरी से डेटा लाना धीमा है।
मुख्य अवधारणा:
Cache Memory एक छोटी, तेज गति की मेमोरी है जो CPU और मुख्य मेमोरी के बीच स्थित होती है।
यह बार-बार उपयोग किए जाने वाले डेटा और निर्देशों को संग्रहीत करती है।
अन्य विकल्प:
Address Decoder - मेमोरी स्थान चुनता है (भंडारण नहीं)
Instruction Set - CPU संक्रियाओं को परिभाषित करता है -
