UNIT 1.1 Systems architecture

Q1: Processors have a speed measured in

• Hertz
• Bits
• Bytes
• Seconds

Q2: Data and Instructions in use are stored in the:

• Processor
• Embedded System
• Hard Disk Drive
• Main Memory

Q4: What doesn’t affect the performance of the computer

• Clock Speed
• Number of Cores
• Cache Size
• The number of instructions in the program

Q5: If the number of cores goes up from 2 to 4 – what is the exact effect on performance?

• Performance decreases
• The max number of instructions executed per second doubles
• max number of instructions executed per second quadruples
• The max number of instructions executed per second is halved

Q6: If the cpu speed goes up from 1GHZ to 4GHZ–what effect on performance?

• The max number of instructions executed per second doubles
• max number of instructions executed per second quadruples
• The max number of instructions executed per second is halved
• max number of instructions executed per second is quartered

Q7: Speed goes up from 2GHZ to 4GHZ , number of cores 2 to 4 – what effect on performance?

• The max number of instructions executed per second doubles
• max number of instructions executed per second quadruples
• The max number of instructions executed per second is halved
• max number of instructions executed per second is quartered

Q8: Speed go from 1GHZ to 4GHZ & cpu goes from 8 core to a dualcore–what effect on performance?

• The number of instructions executed per second doubles
• The number of instructions executed per second quadruples
• The number of instructions executed per second is halved
• number of instructions executed per second stays the same

Q9: System where software & hardware are integrated on a circuitboard together?

• Desktop System
• Embedded System
• Operating System
• Point of Sales System

Q10: Which is an example of an Embedded System:

• Laptops
• Tablets
• PCs
• Microwave

Q11: Processors don’t do the following

• Process Data
• Execute Instructions
• Execute Data
• Operate in Hz
