4. Explain the features of different generations of computers.

Generations of Computers

Computers have evolved significantly over time, with each generation characterized by distinct technological advancements. Here's a breakdown of the key features of each generation:

First Generation (1940s-1950s)

• Technology: Vacuum tubes
• Size: Large and bulky
• Programming: Machine language
• Speed: Slow processing speed
• Applications: Primarily scientific and military research

Second Generation (1950s-1960s)

• Technology: Transistors
• Size: Smaller and more reliable
• Programming: Assembly language
• Speed: Faster processing speed
• Applications: Business and scientific applications

Third Generation (1960s-1970s)

• Technology: Integrated circuits (ICs)
• Size: Even smaller and more efficient
• Programming: High-level languages (e.g., COBOL, FORTRAN)
• Speed: Much faster processing speed
• Applications: A wider range of applications, including personal computing

Fourth Generation (1970s-present)

• Technology: Microprocessors
• Size: Very small and portable
• Programming: Object-oriented programming languages (e.g., C++, Java)
