Identify key figures in computer history and describe the five generations of computers.

Here's the solution to the activities:

Activity 1.1 Historical Development of Computers

Here are 4 major figures who contributed to the development of computers and their approximate years of significant contribution:

• Charles Babbage (1820s-1830s): Known as the "Father of the Computer" for conceiving the Difference Engine and the Analytical Engine, which laid the theoretical groundwork for modern computers.
• Ada Lovelace (1840s): Often regarded as the first computer programmer for her work on Babbage's Analytical Engine, where she wrote what is considered the first algorithm intended to be carried out by a machine.
• Alan Turing (1930s-1940s): Developed the concept of the Turing machine, a theoretical model of computation, and played a pivotal role in breaking the Enigma code during World War II with the Bombe machine.
• John von Neumann (1940s): Proposed the von Neumann architecture, a design model for stored-program computers that is still fundamental to most modern computers.

Activity 1.2 Generation of Computers

Here is a table summarizing the five generations of computers:

Generation	Technology	Storage Medium	Language	Example
First (1940s-1950s)	Vacuum Tubes	Magnetic Drums, Magnetic Tapes	Machine Language	ENIAC, UNIVAC I
Second (1950s-1960s)	Transistors	Magnetic Cores, Magnetic Disks	Assembly Language, FORTRAN, COBOL	IBM 7090, CDC 1604
Third (1960s-1970s)	Integrated Circuits (ICs)	Magnetic Disks, Semiconductor Memory	High-Level Languages (BASIC, Pascal)	IBM System/360, PDP-8
Fourth (1970s-Present)	Microprocessors (VLSI)	Hard Disks, Floppy Disks, Optical Disks, Flash	High-Level Languages (C++, Java, Python)	Personal Computers (IBM PC, Apple Mac)
Fifth (Present & Beyond)	Artificial Intelligence, Parallel Processing	Advanced storage, Cloud Storage	AI Languages (Prolog, LISP), Natural Language	Robotics, Expert Systems, Voice Recognition
