Complete MIS 180 Midterm #2 Study
Guide (Meader SDSU)With All Correct &
Verified Answers
CPU/Processor Correct answer-The actual hardware that interprets and executes the program
(software) instructions and coordinates how all other hardware devices work together
EX: arithmetic, evaluation conditions, compare #, letters, characters
Processor Clock Speed Correct 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) Correct 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) Correct 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) Correct 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 Correct answer-Short for Binary digit, smallest element of data, either 0 off or 1 on
Byte Correct answer-group of 8 bits, operate as single unit
KB Correct answer-kilobyte 1,024 Bytes (10^3)
MB Correct answer-megabyte, 1,024 KB (10^6)
GB Correct answer-gigabyte, 1,024 MB (10^9 bytes)
TB Correct answer-terabyte, 1,024 GB (10^12 bytes)
PB Correct answer-petabyte, 1,024 TB (10^15 bytes)
Operating System Correct answer-Controls the application software and manages how the
hardware devices work together
, Application Software Correct answer-Used for specific information processing needs; used to solve
specific problems or perform specific tasks
Humans create apps/programming lang Correct answer-(Java, Python, C++, C#, VisualBasic)
programming lang lets humans write instructions in source code telling computer what to do
Source Code Correct answer-contains instructions written by a programer specifying the actions to
be performed by computer software (looks like english)
EX: if score is >=4.0 then print "grade is A"
Object Code Correct answer-looks like numbers- what the computer understands
EX: 10010010
Open Source Correct answer-1) user owned, customizable, free, self/hired maintenance, world
wide community of developers add to it.
2) Refers to any software whose source code is made available free (not on a fee or licensing basis as
in ebusiness) for any third party to review and modify
Proprietary (Code) Correct answer-Vendor owned(apple/microsoft), not changeable, any price
vendor charges to acquire, vendor maintained, developers for vendors add features
General Purpose app Correct answer-Requires a minimal investment and is used to conduct a wide
variety of operations. However, it may not fulfill all of a business' needs
EX: software suites, web browser, email, word process
Functional app Correct answer-More expensive and do less tasks, but they will be able to serve the
exact function you need them for.
EX: business acct, transaction processing, customer relationship, management
3 ways that businesses acquire software Correct answer-1) Custom buit (self programmed)
2) Commercial/Off the shelf (buy it or get free if open source)
3) Cloud (rent or subscribe)
Structured Data Correct answer--Facts (name, order numb, quantity, location, time)
-Questionnaire
-Bibliographic info
-Online behavior (Clicks, Views, Links, Game Moves)
-Constructed data (sentiment mood intent)
-Meta data (data about data)
