State what the given acronym or abbreviation stands for: “MBR”
Master Boot Record
Which of the following program-processor configuration has the highest speed up?
a.) 5% serial code using 4-core CPU
b.) 10% serial code using 5-core CPU
c.) 15% serial code using 6-core CPU
d.) 20% serial code using 8-core CPU
e.) 25% serial code using 16-core CPU
Solution: Using Amdahl’s Law:
𝑆(𝑛)=1/(𝐵+1/𝑛(1-B))
10% serial code using 5-core CPU
Whichh among the given bus configuration has the highest possible bandwidth?
a.) 10-bit bus @ 35 Mhz
b.) 8-bit bus @ 40 Mhz
c.) 12-bit bus @ 30 Mhz
d.) 20-bit bus @ 18 Mhz
e.) 16-bit bus @ 25 Mhz
Solution:
𝐵=𝑛𝑜.𝑏𝑖𝑡𝑠 𝑖𝑛 𝑏𝑢𝑠/𝑐𝑦𝑐𝑙𝑒 × 𝐹𝑟𝑒𝑞𝑢𝑒𝑛𝑐𝑦
𝐵= 𝑛𝑜.𝑏𝑖𝑡𝑠 𝑖𝑛 𝑏𝑢𝑠𝑐𝑦𝑐𝑙𝑒 × 𝑐𝑦𝑐𝑙𝑒/𝑠
16-bit bus @ 25 Mhz
This can be defined as the basic unit of microprocessor utilization
thread
State what the given acronym or abbreviation stands for: “UEFI”
Unified Extensible Firmware Interface
True or false:
The number of bits in the address bus determines the maximum capacity of memory that can be address by the computer system.
False: number of bits —> width
True or False:
A 20-bit wide bus can access a memory with a maximum capacity of 1,054 kilobytes.
False: 1,048.576 KB
State what the given acronym or abbreviation stands for: “AHCI”
Advanced Host Controller Interface
State what the given acronym or abbreviation stands for: “GPT”
Globally Unique Identifier Partition Table
Referring to the scaled image of an M.2 SSD as compared to a 2.5” SATA-SSD below, identify the form factor?
2260
This type of computing is performed when microprocessor carries just one-machine level at any given time.
Serial Computing/Processing
This type of memory is derived from the operating system’s use of the HDD/SSD to temporarily write and read information to simulate a larger memory capacity.
Virtual Memory
True or False
In any microprocessor the number of threads is equal to twice the number of cores.
False
This is a distinct, independent, physical computing inside a CPU.
Core
True or False
The level 1 cache is manufactured with in the same die of the microprocessor core.
True
A unitless quantity that express the ratio between the serial execution time over the parallel execution time when using a multi-threaded CPU.
Speedup
State what the given acronym or abbreviation stands for: “IOPS”
Input/Output Operations per Second
True or False
A Western Digital WD-Purple hard Drive is designed primarily for use in file servers.
False: WD-Purple —–> WD-Red
Which of the following drives does not belong to the group?
a.) Compact Disc Drive
b.) Floppy Disc Drive
c.) Solid State Drive
d.) Blu-ray Disc Drive
e.) Hard Disc Drive
Floppy Disc Drive
A firmware used to perform hardware initialization during the booting process (power-on startup), and to provide runtime services for operating systems and programs.
Basic Input/Output System
The mini-SATA SSD form uses what data storage communication protocol?
AHCI
