• What is the definition of a CPU?A. The physical computer case that contains all its internal componentsB. The computer’s internal hard driveC. A part of the computer whose function is to perform data processingD. A part of the computer that stores and manages memory

  C.  A CPU is the central processing unit, a microprocessor that performs
       data processing, or interprets and executes instructions.

• What is the definition of POST?A. A set of computer sequences the operating system executes upon a proper    shutdownB. A diagnostic test of the computer’s hardware and software for presence and    operability during the boot sequence prior to running the operating systemC. A diagnostic test of the computer’s software for presence and operability     during the boot sequence prior to running the operating systemD. A diagnostic test of the computer’s hardware for presence and operability     during the boot sequence prior to running the operating system

    D. POST (Power On Self-Test) is a diagnostic test of the computer’s hardware,
        such as the motherboard, memory, CD-ROM drive, and so forth. POST does
        not test the computer’s software

• Is the information stored on a computer’s ROM chip lost during a proper shutdown?A. YesB. No

  B. Information contained on a ROM chip, read-only memory, is not lost after the computer has been shut down.
  
  Read-only memory (ROM) is a type of non-volatile memory used incomputers and other electronic devices. Data stored in ROM can only be modified slowly, with difficulty, or not at all, so it is mainly used to storefirmware (software that is closely tied to specific hardware and unlikely to need frequent updates).

• Can information stored in the BIOS ever change?A. YesB. No

  A. Although not very common, information stored in the BIOS can change,
      such as when the BIOS needs to be upgraded to support new hardware.

• What is the purpose or function of a computer’s ROM chip?A. Long-term or permanent storage of information and instructionsB. Temporary storage area to run applicationsC. Permanent storage area for programs and filesD. A portable storage device

  A. ROM (read-only memory) contains information about the computer, such as
      hardware configuration. Unlike RAM, the information is not lost once power is
      disconnected

• Information contained in RAM memory (system’s main memory), which is located on the motherboard, is _________.A. VolatileB. Nonvolatile

  A. Information contained in RAM memory is considered volatile, which means that
      the data is lost after the computer has been disconnected

• What is the maximum number of drive letters assigned to hard drive(s) partitions on a system?A. FourB. SixteenC. Twenty-fourD. Infinity

  C. The answer is 24 drive letters (C–Z), with drive letters A and B reserved
      for floppy drives.

• The smallest area on a drive that data can be written to is a _______ whilethe smallest area on a drive that a file can be written to is a _______.A. Bit and byteB. Sector and clusterC. Volume and driveD. Memory and disk

  B. Data is written to sectors, and files are written to clusters.

• The size of a physical hard drive can be determined by which of the following?A. Multiplying the cylinder x head x sectorB. Multiplying the cylinder x head x sector x 512 bytesC. Multiplying the total LBA sectors times 512 bytesD. Adding the total size of partitionsE. Both B and C

  E. Multiplying C/H/S gives the total amount of sectors in older systems if the
      number of sectors per track is constant. When it’s not, total LBA sectors
      give total sectors. Multiplying the total number of sectors from the
      appropriate method times 512 bytes per sector gives the total number
      of bytes for the physical drive. Adding up the total size of partitions does
      not include areas outside the partitions, such as Unused Disk Area.

• 12. Which is not considered an output device?A. MonitorB. PrinterC. CD-RW driveD. Speaker

  C. A CD-RW (rewritable) drive is both an input and output device, as opposed to a CD drive, which only reads and inputs data to the computer system.
