Question 1

Question
Memory VOLATILE
Answer
  • Only stores information to run programs while the PC is off. Don`t requires electricity to store data using transistors and capacitor
  • Retains data even when the computer is off. Examples in old computers: paper, punched tape and floppy disks
  • Only stores information to run programs while the PC is on. Reset when the PC is turned off. Requires electricity to store data using transistors and capacitor
  • Don`t retain data even when the computer is on. Examples in old computers: paper, punched tape and floppy disks

Question 2

Question
Memory NON-VOLITILE
Answer
  • Retains data even when the computer is off. Examples in old computers: paper, punched tape and floppy disks
  • Reset when the PC is turned off.
  • Requires electricity to store data using transistors and capacitors
  • Retains data even when the computer is on.

Question 3

Question
Latency is the time for components to [blank_start]respond to a request[blank_end]
Answer
  • respond to a request

Question 4

Question
Bridges
Answer
  • is the area where the computer stores or remembers data.
  • Manage how data and instructions are transferred between devices
  • provides the CPU with its instructions.
  • Primary storage

Question 5

Question
Cores
Answer
  • Manage how data and instructions are transferred
  • is the time for components to respond to a request
  • communicate through channels therefore doubling cores does not double speed
  • Retains data even when the computer is off.

Question 6

Question
Memory
Answer
  • Executes programs using the fetch-decode-execute cycle
  • Used to access the performance of a computer.
  • Examples Registers, cache, RAM, ROM and Virtual
  • Stores program operations and data while the program is being executed. Memory

Question 7

Question
Storage means
Answer
  • Renders images, frees up the CPU for other tasks
  • Retain programs and files long term, even when not in use.
  • executes programs using the fetch-decode-execute cycle

Question 8

Question
Benchmarking means
Answer
  • A test used to access the performance of a computer. Different types of software are used depending on the computers purpose.
  • Stores program, operations and data while the program is being executed.
  • Registers, cache, RAM, ROM and Virtual Memory
  • CPU speed (cycles per second)

Question 9

Question
Computers require an input hardware, processing hardware and output hardware.
Answer
  • True
  • False

Question 10

Question
CPU speed (cycles per second) measured in .............................
Answer
  • Gigabytes
  • ROM
  • RAM
  • Hertz

Question 11

Question
Factors that affect CPU performance are
Answer
  • Processor type, cache, clock speed
  • Processor type and cache
  • Processor type and clock speed
  • Only cache

Question 12

Question
Cache is a small amount of memory which is a part of the CPU - closer to the CPU than RAM. It is used to temporarily hold instructions and data that the CPU is likely to reuse.
Answer
  • True
  • False

Question 13

Question
The CPU control unit checks the -------------------- for instructions before the RAM.
Answer
  • Operating system
  • Memory
  • Clock
  • Cache

Question 14

Question
Larger the Cache =
Answer
  • indicates how fast the CPU can run.
  • determines how many instruction cycles the CPU can deal with in a second.
  • less data can be stored closer to the CPU
  • more data can be stored closer to the CPU

Question 15

Question
The clock speed - also known as clock rate -
Answer
  • depends on the size of the cache
  • indicates how fast the CPU can run.
  • stores programs, data and instructions.
  • allows the communication between devices

Question 16

Question
Clock speed is measured in megahertz (mHz) or gigahertz (gHz)
Answer
  • True
  • False

Question 17

Question
Clock speed is measured in megahertz (mHz) or gigahertz (gHz) and corresponds with how many instruction cycles the CPU [blank_start]can deal with in a second[blank_end].
Answer
  • can deal with in a second

Question 18

Question
CPU can contain one or more processing units also known as
Answer
