Benchmarking is test on different configurations to determine the speed of components of computer
Unit 1 and Unit 2 Review Materials
Volatility means that when the power is lost the data stored in RAM is also lost.
Accessing RAM directly increases the speed of information retrieval.
RAM is accessed directly via its address
The speed of RAM is measured in nanoseconds.
RAM is random access memory. It is the main storage for data, holding the data before and after processing.
What is the unit of measurement typically used for the speed of RAM?
b. What is SDRAM and how does it work?
SDRAM is Synchronous Dynamic RAM, a type of DRAM that is fast and relatively inexpensive. It is synchronously clocked to the system bus. This means that RAM can send out data to the CPU for each tick of the clock..
c. Data on hard disk drives is accessed indirectly via the file system.
i. How is data in RAM accessed?
ii. What are the benefits of accessing RAM in this way?
d. With regard to RAM, what is volatility?
Note: The questions on the exam will be based on variations of the following pool of questions and exercises in Unit 1 and Unit 2.
- Benchmarks
a. With regard to computing, define the term benchmark.
What tasks does benchmarking software perform in order to measure the system being tested?
b. How can consumers use benchmarks to help them purchase a computer system?
