The Evolution of Technology

• Technology: Any invention, including tools, machines, techniques, and sources of power.
• Computer: An electronic device that can store and process data to help users complete tasks.
• Computers: Everywhere, in all shapes and sizes, found in schools, homes, workplaces, and various items like cash registers and refrigerators.

Computer

A computer is an electronic device that can store and process data to help users complete tasks. It is a powerful tool that has revolutionized the way we work, communicate, and entertain ourselves. From browsing the internet to playing video games, computers have become an essential part of our daily lives. They have evolved over the years, becoming faster, smaller, and more efficient. Without computers, our modern world would not be the same.

The Evolution of Technology

• Hardware: Physical components of a computer
• Software: Set of instructions or programs
• System Software: Controls and analyzes hardware
• Application Software: Helps users complete specific tasks
• Three Basic Computer Functions: Input, Processing, Output

Computer Functions

• Input: The process of entering data into a computer system.
• Processing: The manipulation and transformation of data by a computer.
• Output: The presentation or display of processed data by a computer.

Data Storage

• Data Storage: When information is saved by a computer.
• Short-term/ temporary: RAM - Random Access Memory. Fast access for CPU, not saved when computer is turned off.
• Long-term Memory: Where unused information is stored. Can be added to and deleted from.

ROM - Fast Access, No Power

ROM stands for Read Only Memory. It provides fast access for the CPU but does not retain data when the computer is turned off. It stores permanent instructions that are essential for booting up the system. Unlike RAM, ROM cannot be modified or erased by normal computer operations. It is a crucial component in every computer system.

The Evolution of Technology

• Data Storage: Information remains on storage devices like CDs, DVDs, memory cards, and USB flash drives.
• Cloud Storage: Access data from anywhere, backup files, and easily share documents.
• Why Cloud Storage: Anytime access, ease of use, backup, and document sharing.
• Data Storage and Movement: Understand short-term and long-term storage, and how data is stored and moved.

Cloud Storage:

Anytime access is the main advantage of cloud storage. It allows you to access your files from anywhere, at any time. No more worrying about forgetting your USB drive or losing important documents. With cloud storage, your files are always just a click away.

• Easily share documents with others
• Automatic backup for peace of mind
• Simple and user-friendly interface
