1. Explain the evaluation of computer? 2. Recognize the difference types of computer 3. Explain the characteristics of computer 4. Explain how computer works
Answer (1)
Answer:1. Evaluation of ComputerThe evaluation (or evolution) of computers refers to the history of how they developed over time:First Generation (1940s–1950s) – Used vacuum tubes, very large, and slow.Second Generation (1950s–1960s) – Used transistors, smaller, faster, more reliable.Third Generation (1960s–1970s) – Used integrated circuits (ICs), more compact, increased speed.Fourth Generation (1970s–present) – Microprocessors were developed, personal computers became common.Fifth Generation (present and beyond) – Focuses on artificial intelligence, quantum computing, and advanced processing.2. Different Types of ComputersSupercomputer – Extremely fast and powerful, used for complex scientific tasks.Mainframe – Large computers used by big organizations for bulk data processing.Minicomputer – Mid-sized, used for specific business or manufacturing purposes.Microcomputer – Personal computers like desktops and laptops.Embedded Computer – Built into other devices (e.g., cars, appliances, smart gadgets).3. Characteristics of a ComputerSpeed – Can process millions of instructions per second.Accuracy – Performs tasks with minimal errors (errors usually come from human input).Automation – Can work without continuous human control once programmed.Storage – Can store large amounts of data.Versatility – Can perform a wide variety of tasks.Connectivity – Can connect to other devices and networks.4. How a Computer WorksA computer follows the IPO cycle (Input → Process → Output):1. Input – Data is entered (keyboard, mouse, sensors, etc.).2. Process – The CPU processes data according to instructions.3. Output – The results are displayed (monitor, printer, speakers, etc.).4. Storage – Data can be stored for future use (hard drive, cloud, etc.).
