Study Notes

Data Storage Units

A floppy disk can store 1.44 MB of data, which is equivalent to more than a million characters.
A hard drive can hold 1 TB of data.
One bit represents a single binary value (1 or 0).
One byte consists of 8 bits and stores one ASCII character.
1 kilobyte (KB) equals 1,024 bytes.
1 megabyte (MB) equals 1,024 KB.
1 gigabyte (GB) equals 1,024 MB.
1 terabyte (TB) equals 1,024 GB.
1 petabyte (PB) equals 1,024 TB.
1 exabyte (EB) equals 1,024 PB.

Processing Devices

A processing device receives data, processes it, and outputs results.
The Central Processing Unit (CPU), also known as the processor or microprocessor, is a key processing device.
The CPU's primary components are the Arithmetic Logic Unit (ALU), the Control Unit (CU), and the Memory Unit.

Motherboard

The Motherboard, or Logic board on Apple computers, connects all computer components.
It houses the CPU, RAM, BIOS, expansion slots, and back panel.

Expansion Slots

These slots allow expansion cards to be added for new features.

Paragraph Formatting

Borders and shading highlight paragraphs.
Indents and tab stops improve paragraph clarity.
The default tab stop moves the cursor ½ inch to the right, which can be customized.
Tab stop types include left, center, right, decimal, bar, first line indent, and hanging indent.

Page Formatting

Page size options include Letter (8.5" x 11") and A4 (8.27" x 11.60").
Page Orientation can be Portrait (vertical) or Landscape (horizontal).
Page margins are the space between the text and the edge of the document.
Headers and Footers are areas at the top and bottom of pages.
