MIS 180 MEADER PROFESSIONAL
INFORMATION SYSTEMS PREP QUESTIONS
AND ACCURATE ANSWERS GRADED A+
●● Processor Clock Speed
Answer: The speed of the internal clock on the CPU that sets the pace
that operations go at within the computer's internal processes circuitry,
measured in Ghz
(Ghz=frequency of electricity)
●● Primary Storage/RAM (Random Access Memory)
Answer: -the computer's main memory, contains RAM, cache memory,
and ROM. It is directly accessible to the CPU.
-Stores data directly accessible by computer's CPU, access with minimal
delay, stores data loaded by active programs and operating systems, uses
electrical current
●● Secondary Data Storage (Hard disk/ External drive/Internal Hard
Drive)
Answer: -Equipment designed to hold large volumes of data for long
term storage, nonvolatile, do not lose their information when the
computer is turned off, Hard disk or external drive
,-Not directly connected with CPU, hard drive sends and receives data
through an I/P bus, may pass through other memory before getting to
CPU, not as fast, retain data when comp is off, stores magnetically
●● ROM(Read Only Memory)
Answer: Portion of a computer's primary storage that does not lose its
contents when the computer is turned off, it contains essential programs
that neither the computer, nor the user can erase, uses flash memory
●● Bit
Answer: Short for Binary digit, smallest element of data, either 0 off or 1
on
●● Byte
Answer: group of 8 bits, operate as single unit
●● KB
Answer: kilobyte 1,024 Bytes (10^3)
●● MB
Answer: megabyte, 1,024 KB (10^6)
●● GB
, Answer: gigabyte, 1,024 MB (10^9 bytes)
●● TB
Answer: terabyte, 1,024 GB (10^12 bytes)
●● PB
Answer: petabyte, 1,024 TB (10^15 bytes)
●● Operating System
Answer: Controls the application software and manages how the
hardware devices work together
●● Application Software
Answer: Used for specific information processing needs; used to solve
specific problems or perform specific tasks
●● Humans create apps/programming lang
Answer: (Java, Python, C++, C#, VisualBasic) programming lang lets
humans write instructions in source code telling computer what to do
●● Source Code
Answer: contains instructions written by a programer specifying the
actions to be performed by computer software (looks like english)
