EECS 1520 Test 1 2026 (EECS 1520) – 180 Questions & Answers – Hardware Generations, Software Evolution, Data Representation & Logic Gates

This document contains approximately 180 fully solved EECS 1520 Test 1 2026 exam questions and answers covering foundational computing systems concepts, hardware and software evolution, data representation, file systems, networking, and digital logic. It begins with core definitions such as computing systems (hardware, software, data), abstraction, and layered architecture (information, hardware, programming, operating system, application, communication), as outlined in the opening pages of the document. The material provides comprehensive coverage of early computing pioneers and devices including Pascal, Leibniz, Jacquard Loom punch cards, Babbage’s Analytical Engine and Difference Engine, Ada Lovelace, Hollerith’s tabulator, Alan Turing, ENIAC, EDVAC, and UNIVAC. It thoroughly explains first through fourth generation hardware (vacuum tubes, magnetic drums, magnetic tape, transistors, magnetic core, magnetic disks, integrated circuits, large-scale integration, PCs and workstations) and traces the evolution of software from machine language and assembly to high-level languages, structured programming, operating systems (UNIX, MS-DOS), object-oriented design, and the rise of Microsoft and the World Wide Web. In addition, the document examines networking fundamentals (ARPANET, LAN, Internet), file systems (sequential vs direct access, directories, root directory, absolute and relative paths), data representation (analog vs digital data, analog and digital signals), multimedia concepts (audio formats, colour depth, RGB values, raster vs vector graphics, compression techniques), and core digital logic principles including the six fundamental logic gates (NOT, AND, OR, XOR, NAND, NOR). It integrates theoretical explanations with concise exam-ready definitions designed for strong conceptual understanding and high test performance. This study resource is particularly relevant for: Students enrolled in EECS 1520 Introduction to Computer Science Computer Science and Engineering majors Information Technology students Electrical Engineering students Students preparing for Test 1 or midterm examinations in foundational computing courses It is suitable for courses such as: Introduction to Computer Science Fundamentals of Computing Systems Digital Logic Foundations Computer Hardware and Software Basics Data Representation and Multimedia Systems This document functions as a comprehensive Test 1 preparation guide, reinforcing key terminology, historical developments, system architecture layers, hardware and software generations, file management concepts, networking principles, data encoding, multimedia fundamentals, and essential logic gate operations.
