What is the primary characteristic that distinguishes a personal mobile device from a PC? -
answer-Its portability and battery operation.
What is the key difference in behavior between volatile and nonvolatile memory when a
computer loses power? - answer-Volatile memory loses its data, while nonvolatile memory
retains it.
What is the primary advantage of using parallel processing in a computer system? - answer-It
allows for the simultaneous execution of multiple tasks.
What does a compiler primarily do in programming? - answer-Translates high-level
programming language statements into assembly language.
What is the essential role of memory components within a computer system? - answer-To store
both active programs and the data they are currently processing.
Compared to DRAM, what are the key advantages and disadvantages of SRAM? - answer-SRAM
is faster, more reliable, and does not need refreshing, but it is more expensive and larger.
[Case Study]: Imagine you are designing a new smart home device, like a thermostat that learns
your preferences. What type of computer would be most suitable for this device, and why? -
answer-An Embedded Computer would be the most suitable type of computer for a smart
thermostat. This is because an embedded computer is a computer system integrated as part of
1
,a larger device to perform specific functions. In this case, the embedded computer would be
built into the thermostat to manage temperature control, learn user preferences, and
potentially communicate with other smart home devices, without needing the full capabilities
or user interface of a personal computer.
[Compare]: Differentiate between Systems Software and Application Software. Provide an
example of each and explain their relationship. - answer-Systems Software is designed to
manage and control computer hardware and provide a platform for other software to run. It
acts as an interface between the hardware and application software. Examples include
operating systems (like Windows or macOS) and device drivers. Application Software, on the
other hand, is designed to perform specific tasks for the user. Examples include word
processors, web browsers, and games. Application software relies on systems software to
interact with the hardware and function correctly.
What is the function of cache memory in a computer system? - answer-To act as a buffer
between the CPU and slower main memory, speeding up access to frequently used data.
What is the purpose of abstraction in computer architecture? - answer-To simplify complex
systems by hiding lower-level operational details.
What is the primary function of an input device in a computer system? - answer-To feed
information into a computer.
What is the main benefit of mass production for Integrated Circuits (ICs)? - answer-It enables
the efficient mass manufacturing of cost-effective electronic components.
What is the primary function of systems software? - answer-To manage and control computer
hardware, acting as an interface.
What is the primary function of an embedded computer? - answer-To perform specific
2
,functions as part of a larger device or system.
What is the primary goal of the 'Common Case Fast' principle in computer architecture? -
answer-To improve the performance of the most frequently executed operations.
What is the primary purpose of a supercomputer? - answer-To perform complex scientific
calculations and simulations.
What is the primary function of a Central Processing Unit (CPU) in a computer system? -
answer-To execute program instructions.
[Compare]: Compare and contrast DRAM and SRAM memory. Consider their speed, cost,
volatility, and typical uses within a computer system. - answer-DRAM (Dynamic Random Access
Memory) is volatile, serving as main memory, offering larger capacity at a lower cost per bit but
slower speeds and requiring refreshing. SRAM (Static Random Access Memory) is also volatile,
but it is faster, more reliable, and does not require refreshing. However, it is more expensive
and has a larger physical footprint. SRAM is often used for cache memory, while DRAM is used
for main memory.
What hardware components constitute the datapath? - answer-The hardware components
responsible for processing data.
How does the strategy of dependability via redundancy enhance system reliability? - answer-It
incorporates duplicate components or data to enable continued operation despite failures.
What are the two main roles of an operating system? - answer-Managing hardware resources
and providing services for programs.
What is the role of prediction in computer architecture? - answer-To anticipate the outcome of
3
, future events or operations.
What is the function of an assembler? - answer-Translates assembly instructions into machine
language.
What is the primary characteristic of secondary memory components like Flash Memory and
magnetic disks? - answer-They are nonvolatile, retaining data even when the power is turned
off.
What is the primary role of control components within a computer system? - answer-To fetch
instructions and direct the operation of the datapath and other hardware.
How does cloud computing deliver its services? - answer-Through vast networks of servers
providing services over the internet.
What is the defining characteristic of a multicore processor? - answer-It is a single integrated
circuit with multiple independent processing units.
What is the relationship between an operating system and systems software? - answer-An
operating system is a specific type of systems software.
What is the relationship between parallelism and multicore processors? - answer-Multicore
processors enable parallelism by allowing multiple tasks to be executed simultaneously.
[Compare]: Explain the fundamental differences between a Personal Computer (PC), a Server,
and a Supercomputer, focusing on their primary purpose, typical users, and performance
capabilities. - answer-A Personal Computer (PC) is designed for individual use, performing tasks
for a single user. A Server is specialized to run programs and provide services to multiple client
computers simultaneously, often handling tasks like web hosting or file storage. A
Supercomputer is a high-performance server optimized for extremely complex scientific
