Definition: A programmable electronic device that accepts data, performs operations on that data, and stores the results as needed.
Functionality: Computers follow instructions called programs that dictate their operations.
Hardware
Internal Hardware: Located inside the system unit
External Hardware: Connects via wired or wireless connections
System Software
Operating System: Manages computer activities
Utilities: Example programs for optimization and diagnostics
Application Software
Programs for specific tasks (e.g., word processing, gaming)
1. Input: Entering data into the computer.
2. Processing: Performing operations on the data.
3. Output: Presenting the processed information.
4. Storage: Saving data for future use.
5. Communications: Sending and receiving data.
Data: Raw and unorganized facts, which can be text, graphics, audio, or video.
Information: Data processed into a meaningful form.
Information Processing: The mechanism of converting data into information.
Definition: Embedded within products for specific tasks (e.g., household appliances, thermostats).
Characteristics: Generally not general-purpose computers.
Description: Small devices with computing capabilities, typically based on mobile phones.
Examples: Smartphones, handheld gaming devices, portable media players.
