FINAL FINAL TEST 2026 QUESTIONS
WITH CORRECT ANSWERS GRADED
A+
◍ When a Java string does not have surrounding double quotes, what type of
error occurs?.
Answer: Compile-time error
◍ 1. Define "metadata" and provide one example..
Answer: set of information that gives data on other pieces of data. a
photograph file because it gives the file size, time taken, and other key
information
◍ Text, like everything else in your computer, is stored as raw binary numbers.
To treat those numbers as characters, they must be encoded. The encoding
scheme used in Java is called:.
Answer: Unicode
◍ 2. Describe the process of "cleaning" data. What happens to corrupt,
incomplete or corrupt data?.
Answer: Cleansing data refers to repairing or replacing inaccurate or
incomplete data in a data set. The process cleanses, deletes, or replaces
corrupt data files.
◍ 3. Define an "intractable" problem. Redefine it using your own words..
Answer: Intractable problems are problems where no efficient algorithms
exist to solve them. "Computationally hard."
◍ Programs that are designed to "work for you", carrying out a task you
specify, are known as:.
, Answer: application programs
◍ The devices that feed data and programs into computers are called ______..
Answer: input devices
◍ If your java source code program compiles, but displays an error message
when you run it, then it must have a:.
Answer: Run-time error
◍ What is the computer component that stores program instructions during a
program execution?.
Answer: Memory
◍ 4. The Internet uses all different types of hardware made from different
companies. How does this work? (Different vendors make different styles of
products - explain how all of them seem to work)..
Answer: Protocols allow for different manufacturers to produce equipment
for the internet. If protocol followed, internet works.
◍ 5. With large data sets come large problems. Explain at least 3 problems that
come with handling/managing large data sets..
Answer: 1. Validating data - There is often discrepancies within big data.2.
Managing data growth - It can be difficult to control large incoming sets of
data.3. Securing data - Security within large data sets can be difficult to
manage with overwhelming amounts of information.
◍ 6. Define "scalability". Explain how it applies to the Internet..
Answer: Scalability is what allows for protocols and equipment to expand
without a loss of performance. The internet=scalable bc it adds routers and if
protocols are followed, service is not negatively impacted.
◍ Each memory cell has a unique location in main memory, called the
_________..
Answer: address
◍ What does the following line of code print out to the
console?System.out.println("\"\\ / \\\\ // \\\\\\ ///\"");.
