PROGRAMMING

Hardware: Tangible, physical parts of the computer

Software: Parts of the computer that you can’t touch

Motherboard: Connects all the parts together

Processor:

• The central processing unit (CPU) performs program control and data processing

• Like a brain, it controls info & tells other parts what to do

• Performs basic arithmetic operations & logical operations

Operating System:

• Helps the system operate (duh)

• Ex: Windows 10, Linux, MacOS, Android, Windows Phone, iOS 9

Memory:

• Stores data when connected to electricity

• Stores data that your computer needs quickly to help programs run faster

• You can run more than 1 program at once

Storage Devices:

• Slower, less expensive storage that persists w/out electricity

• Data stays practically forever

Monitor:

• Output device

Speaker:

• Output device

Keyboard:

• Input device

Mouse:

• Input device

How data is stored:

• Computer stores data, programs in storage devices, then loads them into memory when you turn your computer on

• Program updates data in memory and writes modified data back to storage

Programming Language

• High-level programming languages fix the problem of coding being too tedious; they allow the user to specify the actions the program acts out

• A compiler translates the high-level languages into CPU instructions
