Advantage and disadvantage of EDVAC
Answer (1)
Answer:EDVAC (Electronic Discrete Variable Automatic Computer) was a pioneering computer developed in the 1940s. Here are its advantages and disadvantages:*Advantages:*1. Electronic Computing: EDVAC was one of the first electronic computers, replacing mechanical relays with vacuum tubes.2. Binary System: EDVAC used binary code, simplifying calculations and programming.3. Stored-Program Concept: EDVAC introduced the stored-program concept, allowing programs and data to be stored in memory.4. Faster Calculations: EDVAC performed calculations faster than earlier computers, with speeds up to 1,000 additions/sec.5. Automatic Computation: EDVAC automated many calculations, reducing human error and increasing efficiency.*Disadvantages:*1. Bulkiness: EDVAC occupied an entire room (7.5 ft × 3 ft × 8.5 ft) due to its vacuum tube-based design.2. Unreliability: Vacuum tubes were prone to overheating, burnout, and reliability issues.3. Limited Memory: EDVAC's memory was limited to 1,024 44-bit words.4. Input/Output Limitations: EDVAC used patch cords and switches for input/output, limiting user interaction.5. Maintenance Challenges: EDVAC required frequent maintenance, tube replacement, and adjustments.6. Power Consumption: EDVAC consumed significant power (about 8 kW).7. Limited Programming: EDVAC's programming was cumbersome, using machine language and patch cords.*Legacy:*Despite its limitations, EDVAC influenced the development of modern computers, including:1. UNIVAC I (1951): First commercially available computer.2. EDSAC (1949): British computer that improved upon EDVAC's design.3. Modern Computer Architecture: EDVAC's stored-program concept and binary system paved the way for modern computer design.EDVAC's innovative design and concepts overcame many limitations, shaping the future of computing.
