Module 6 - Operating Systems and Microprocessor

1.) Which of the following is an OS function that executes several application programs progressively in turn on a single PC, such as when a file is downloaded from a web site while data is processed with spreadsheet software?

• a.) Virtual reality

• b) Dual core

• c) Dual system

• d) Multitasking

2.) Which of the following is a typical example of a system operating on a super computer?

• a)  A Supply Chain Management system that is required for linkage between enterprises

• b)  A global climate change forecast system that requires large-scale scientific and

  technical computing

• c)  A banking system that requires a high reliability

• d)  An engine control system of a vehicle that requires advanced real-time control

3.) The types of programs that are executed at the startup time of a PC are generally classified into three categories: BIOS, OS, and startup services. Which of the following is the list that is arranged in the sequence of the execution of the programs?

• a) BIOS → OS → Startup services

• b) OS → BIOS → Startup services

• c) OS → Startup services → BIOS

• d) Startup services → BIOS → OS

4.) Which of the following is an appropriate description concerning OSs used for PCs?

• a) Since the interface between an OS and application programs is standardized, the

  application programs can be developed without regard to the type of OS.

• b) An OS allocates the computer resources, such as the CPU, memory, and auxiliary storage device, to application programs.

• c) Since an OS has the function of automatically converting character set of a file, application programs can access the file without regard to the character set.

• d) The source code of an OS is required to be disclosed so that application programs can be free to use the various functions of the OS.

5.) The types of programs that are executed at the startup time of a PC are generally classified into three categories: BIOS, OS, and startup services. Which of the following is the list that is arranged in the sequence of the execution of the programs?

• a) BIOS → OS → Startup services

• b) OS → BIOS → Startup services

• c) OS → Startup services → BIOS

• d) Startup services → BIOS → OS

6.) When the types of programs that are executed when a PC is started are broadly classified into three categories, namely BIOS (Basic Input Output System), OS, and resident application program, which of the following is the order of execution of the programs?

• a) BIOS, OS, resident application program

• b) OS, BIOS, resident application program

• c) OS, resident application program, BIOS

• d) Resident application program, BIOS, OS

7.) Which of the following is the most appropriate description concerning a compatible CPU?

• a)It can run the OS or the application software that can be run on the original CPU.

• b) It must not be developed nor manufactured as long as the patents of the original CPU

  are valid.

• c) A compatible CPU for single-core CPU has been developed, while one for multi-core

  CPU does not exist

• d) It is a CPU that is intended to improve the performance of an outdated PC, and is not

  adopted for a new model of PC.

8.) Which of the following is an appropriate description concerning the primary and secondary cache memory that a CPU is equipped with?

• a) The primary cache memory has larger capacity than the secondary cache memory.

• b) The secondary cache memory is slower than the main memory in writing and reading.

• c) When the CPU reads data, it first accesses the primary cache memory, and then it

  accesses the secondary cache memory if no data is available.

• d) All of the data that is required for a process needs to be present on the primary or

  secondary cache memory when a program starts.

9.) Which of the following is an appropriate description concerning a CPU?

• a) The cache memory that is integrated into a CPU is used to virtually extend the

  capacity of the main memory.

• b) A CPU is equipped with the arithmetic and logical function that serves as part of

  control functions.

• c) A CPU is categorized as a 16-bit, 32-bit, or 64-bit CPU depending on the data volume

  processed at a time, but the width in bits is not related to the performance.

• d) For CPUs that have the same architecture, the higher the clock frequency, the faster

  the response time.

10.) Which of the following is an appropriate description concerning the OS for PCs?

• a) Each PC allows only one (1) type of OS to be installed and run on it.

• a) Each PC allows only one (1) type of OS to be installed and run on it.

• c) When an OS is upgraded to a new version, all of the software operating with the old

  version of the OS cannot be used any more.

• d) There exist some OSs for PCs that can be started up by using an external storage

  device, such as a CD-ROM and USB memory, other than the hard disk.
