Questions 1–10 of 10

1. What does the abbreviation SIMD stand for?
Question 1A. Single Instruction Stream and Single Data StreamB. Single Instruction Stream and Multiple Data StreamC. Multiple Instruction Stream and Single Data StreamD. Multiple Instruction Stream and Multiple Data StreamE. Sequential Instruction and Multiple Disk
2. What does the abbreviation MISD stand for?
Question 2A. Multiple Instruction Stream and Multiple Data StreamB. Multiple Index and Single DiskC. Single Instruction Stream and Multiple Data StreamD. Multiple Instruction Stream and Single Data StreamE. Multi-core Instruction Set Design
3. What is a CPU core built of?
Question 3A. Billions of microscopic transistors that process instructionsB. A single large transistorC. A block of hard-disk storageD. A set of network cablesE. Several pages of stored data
4. What is the minimum number of cores required to handle multiple instructions in parallel?
Question 4A. OneB. TwoC. FourD. EightE. Sixteen
5. In the analogy of finding every letter 'A' written on a page, how does SISD behave?
Question 5A. It reads all the letters at once and returns them togetherB. It sends several instructions in parallelC. It reads and returns each 'A' one by one, sequentially, like a traditional human readerD. It reads 'A' and 'B' at the same timeE. It skips letters it has already seen
6. Which problem of SISD does SIMD solve?
Question 6A. The inability to process instructions from more than one userB. The need to move data on floppy drivesC. The lack of security parameters on queriesD. The limited size of the hard diskE. The need to read each letter or word one by one
7. What scenario does MIMD support?
Question 7A. One instruction reading one data element at a timeB. One instruction reading many data elements in parallelC. Many instructions reading the same data element one by oneD. Data being copied from one hard disk to anotherE. Multiple instructions processed in parallel to read multiple data elements, such as all the 'A's and all the 'B's
8. In MISD, how are hundreds of instructions to read the same letter 'A' processed?
Question 8A. One by one, sequentially, which takes a lot of timeB. All at once on a single coreC. By splitting the page across nodesD. By caching the first result and reusing itE. By rejecting all but the first instruction
9. On what do all the multi-instruction or multi-data reads ultimately depend?
Question 9A. The version of the query languageB. The speed of the network connectionC. The size of the page being readD. The number of cores available in the computer, server or nodeE. The amount of free hard-disk space
10. How many types of instruction for pulling data are there in this classification?
Question 10A. TwoB. ThreeC. FourD. FiveE. Six
