Central Processing Unit (CPU): The "brain" of the computer; executes instructions
Memory (RAM): Temporary storage for data and programs
Secondary Storage: Long term storage of data (e.g. hard disk, SSD, CDs/DVDs)
Data Buses: Connects different parts of a computer to transfer data

Main Characteristics of Computers

Speed (GHz): Measured in Gigahertz, indicating processing speed
Reliability: The ability of a computer to perform its intended functions without failures
Capacity (GB): Measured in Gigabytes, indicating data storage capacity

Information System Pillars

Hardware: Physical components (wires, transistors, circuits)
Software: Instructions and data that tell hardware what to do
People: Users involved in managing and using the system

Computer Applications

Healthcare, Communication, Education, Employment, National Security, Governance, Entertainment(3-D viewing), Finance, Transportation(GPS, autonomous driving), Virtual & Augmented Reality

Computer Definition

A programmed machine accepting input (data), processing it into output (information) and storing it for later use (secondary storage).

Parts of a CPU

Arithmetic Logic Unit (ALU): Performs arithmetic and logic operations
Registers: Small, high-speed storage locations
Instruction Fetcher: Retrieves instructions from memory
Instruction Decoder: Decodes instructions for the CPU
Cache: A high-speed memory used to store frequently accessed data
Bus: Connects components of the computer

Types of Storage

Primary Storage (Memory): Temporary storage for actively used data and programs.
Secondary Storage: Long-term (persistent) storage for data and programs

Memory (Primary Storage)

Temporary storage
Holds input data being processed
Holds results of processing
Contains computer control programs

Secondary Storage
