Chapter: 01. Categories Of Computers And Computer Languages
Answer Key
Section A: Multiple Choice Questions
Section B: Fill in the Blanks
user-friendly (or machine-independent, or easier) Section C: True or False
Section D: Short Answer Questions
A Personal Digital Assistant (PDA) is a handheld computer with a touchscreen that helps users organize daily tasks like schedules, calendars, and address book information, often using a stylus for input. Supercomputers are used for tasks such as weather forecasting and rocket launching. The main advantage of high-level languages is that they are easier to read, write, and maintain because they are closer to human languages than machine languages. Section E: Identify and/or Differentiate Concepts/Processes
General Purpose Computer: A type of computer that can perform many different tasks equally well, such as personal computers like laptops.
Special Purpose Computer: A computer designed to do a specific job very quickly and efficiently, and it cannot perform other tasks, such as controlling machines in factories. a. IBM zSeries: Mainframe Computer
b. Laptop: Microcomputer
c. PDP-11: Minicomputer Section F: Diagram-Based Questions
a. This medical device would most likely belong to the Hybrid computer category.
b. It fits this category because it combines features of both analog and digital computers. It likely measures continuous analog signals (like a heartbeat waveform) and then converts them into accurate digital readings (numerical displays) for analysis and precise monitoring. Section G: Long Answer Questions
Computer languages are classified into two major categories: Low-Level Language (LLL) and High-Level Language (HLL). Low-level languages, like Machine Language (1GL) and Assembly Language (2GL), are machine-dependent, difficult for humans to use, and consist of binary code or mnemonics. High-level languages (3GL, 4GL, 5GL) are machine-independent, closer to human languages, and much easier to read, write, and maintain for programmers. Three advantages of using high-level languages for writing computer programs are: they are user-friendly and similar to the English language, making them easy to understand; they require less time to write a program compared to low-level languages; and they are machine-independent, meaning programs developed in them can be run on various computers after translation.
