BIT 200 Final Examination and All
Correct Answers 2025\2026 Updated.
Components of Information System - Answer People, data, software, networks, databases,
SOPs
Difference between Data and Information - Answer Data is a discrete set of objective facts,
records. Information is a message to change the way someone perceives something
What disciplines make up info systems? - Answer It is a mix of organizational psych, statistics,
computer science and math
Major Milestones of Computing - Answer The Eniac is made at UPenn during WWII, followed
by the Univac for commercial sale. The transistor replaced vacuum tubes, next came the
microprocessor. The Alto was the first home computer by Xerox.
Processor - Answer The part of the computer that executes instructions of a computer
program. Also the brain of the computing device.
Moore's Law - Answer Chip performance per dollar doubles every 18 months. In a year and a
half, chips that are same speed as today's toddles should be available for half the price.
Units of memory storage - Answer megabit, megabyte, gigabyte
Difference between byte and bit - Answer Bit is a 0-1 code, there are 8 bits in a byte.
Computers express data as bits. Bytes are a basic unit of storage.
Non-volatile memory - Answer Storage that retains data even when powered down.
Permanent memory like flash or hard drive
Volatile Memory - Answer RAM, temporary memory that disappears when machine is off
Two types of files stored on disk - Answer Program files aka executable files, ones we run a
program. and Data files are what we use in the program
, Application Software vs. System Software - Answer Application software runs on computer
software. Excel is app, Windows 8 is system.
Operating Systems - Answer OS tells hardware what to do, handles simultaneous execution,
manages resources and monitors security. Provide first level of hardware support (Handle
simultaneous program execution, file management, monitor performance, provide tools for
creating user interfaces.)
Multi-tasking - Answer Running two or more programs at one time
Multi threading - Answer Running two or more tasks in the same program at once
Multi processing - Answer managing allocation of tasks among two or more core processors
Why care about simultaneous execution? - Answer The more there is the more efficiently it can
perform to meet the user needs. If this didn't exist we would have to close one program before
starting another.
Virtual Memory - Answer Makes the computer act as if it has more RAM than it actually does,
makes everything run smoother and faster. Comes into play when we run out of main memory.
Source Code - Answer Programming language statements in a form people can read and write.
Translated to object code by compliers and interpreters.
Object Code - Answer Programming in a form computers can read AKA binaries.
Compiled program - Answer something the programmer uses and creates source code from.
Hard to make and very secure, not easy to steal
Interpreted program - Answer runs the source code/compiled program.
Open Source Software - Answer Making source code available to anyone. Results from
voluntary collaboration of developers. Free to everyone
