What we have learnt
- Computers consist of a CPU, memory, and input/output ports.
- Primary memory is directly accessible by the CPU, whereas secondary memory is accessed through I/O channels.
- Computers can be classified based on application, technology used, and size and capacity.
Key Concepts
- -- Central Processing Unit (CPU)
- The brain of the computer responsible for executing instructions and processing data.
- -- Primary Memory
- Volatile memory directly connected to the CPU, used for temporary storage of data and programs.
- -- Secondary Memory
- Non-volatile memory not directly accessible by the CPU, used for long-term storage.
- -- Input/Output Ports
- Physical interfaces through which input and output devices connect to the computer.
- -- Microcomputer
- A compact and inexpensive personal computer that is typically used by individuals.
