Computer architecture
1.
DRAM memory is far less dense and more expensive per bit than SRAM.
True
False
2.
The single clock cycle implementation is the most efficient of the clock cycle designs.
True
False
3.
The principle of locality refers to the fact that programs access a relatively small portion of their address space at any instance of time.
True
False
4.
Memory hierarchies take advantage of temporal locality.
True
False
5.
The reason computers have clock timing is to make the hardware predictable.
True
False
6.
The performance of a computer is determined by three factors: instruction count, clock cycle time, and clock cycles per instruction.
True
False
7.
Even a small amount of cache memory can lead to greater performance due to the principle of locality.
True
False
8.
Since GPUs supplement a CPU, they need to be able to perform all the same tasks that the CPU can.
True
False
9.
Most of the capacity of the memory hierarchy is at the lowest level.
True
False
10.
Cloud computing is a good choice even for those who have a slow Internet connection, because of the advantages it provides.
True
False
11.
Often, simply adding a faster processor to a system isn’t what is needed to improve performance; instead, memory is more likely to show a significant gain in speed.
True
False
12.
Cloud service layers are broadly grouped into two categories, application focused and infrastructure focused.
True
False
13.
In what pipeline stage is the branch target buffer checked?
Fetch
Decode
Execute
Resolve
14.
The technique where multiple instructions are overlapped with each other is known as:
Streaming
Zoning
Pipelining
None of the above
15.
Which of these statements is correct?
Faster memory => higher cost => smaller size
Faster memory => lower cost => greater size
Slower memory => higher cost => smaller size
Slower memory => lower cost => smaller size
16.
All of the following are reasons for the recent popularity of Virtual Machines (VMs) except:
The increasing importance of isolation and security in modern systems
The sharing of a single computer among multiple users, as in cloud computing
The recent boom in mobile devices
The increase in raw speed of processors over the years
17.
In which cloud computing model are applications hosted by a vendor or service provider and made available over a network, such as the Internet?
SaaS
IaaS
PaaS
NaaS
18.
All of the following are advantages of cloud computing except:
Internet connection required for use
Files accessible from anywhere
Greater collaboration
Less resource intensive on local hardware
19.
Which cloud computing model would a company select if they wanted to rent the hardware and operating systems, but do their own development?
IaaS
PaaS
NaaS
This is not possible.
20.
Older CPUs required how many volts to operate?
5V
3.3V
12V
1.1V
21.
The motherboard contains all of the following components except:
BIOS
CPU
Memory
All of the above are included on the motherboard.
22.
Which of the following would be likely to carry video traffic on a motherboard? (pick the best answer)
AGP
IDE
EIDE
