Study Notes
Data Storage Hierarchy
- A bit is a binary digit (0 or 1)
- The data storage hierarchy is:
- 2^n (e.g., 2^1 = 2, 2^2 = 4, 2^3 = 8, etc.)
- 2^10 = 1024 (1 KB)
- 2^20 = 1,048,576 (1 MB)
- 2^30 = 1,073,741,824 (1 GB)
- 2^40 = 1,099,511,627,776 (1 TB)
Units of Data Storage
- Bit: a binary digit (0 or 1)
- Byte: 8 bits (basic storage unit in computer systems)
- Kilobyte (KB): 2^10 bytes ≈ 103 bytes
- Megabyte (MB): 2^20 bytes ≈ 1,000,000 bytes
- Gigabyte (GB): 2^30 bytes ≈ 1,000,000,000 bytes
- Terabyte (TB): 2^40 bytes ≈ 1,000,000,000,000 bytes
Other Related Bytes
- Nibble: a half-byte (4-bit)
- Word: a 2-byte (16-bit) data item
- Doubleword: a 4-byte (32-bit) data item
- Quadword: an 8-byte (64-bit) data item
- Paragraph: a 16-byte (128-bit) area
Text, Dates, and Logical Data
- Text: any group of letters, numbers, or special characters
- Text operators: & (concatenation)
- Text functions: right(), left(), mid(), lower(), upper(), len(), etc.
- Dates: date and time values
- Dates operators: N/A
- Dates functions: now(), today(), hour(), minute(), etc.
- Logical: true or false values
- Logical operators: <, >, =, =
- Logical functions: if(), and(), or(), not(), isblank()

- Selecting a cell: click on the cell once, or use the arrow keys or Enter key
- Entering information: type in the cell, and press Enter or click the check button
- Modifying a cell: double-click on the cell, and click and drag the separator to adjust the column width
- Resizing a row: drag the separator between the rows
Working with Cells and Ranges in Excel
- Selecting a large range of cells: click on the upper left cell, hold the shift key, and click on the lower right cell
- Selecting non-contiguous areas: hold the Ctrl key and click on the cells
- Writing a formula: start with an equal sign (=), and use operators (+, -, *, /, ^) and cell references
Data Processing with Microsoft Excel
- Overview of Excel formulas: use an equal sign (=) to indicate a formula, and use operators and cell references
- Guidelines for writing effective formulas: keep them simple, avoid hiding data values, and break up formulas to show intermediate results
