Hexadecimal Addressing**: It's easier to read and debug than binary and is widely used in computing for tasks like HTML color codes, memory dumps, and IP/MAC addresses.

**Two’s Complement Representation**: To represent -25 as an 8-bit two’s complement integer, convert 25 to binary, flip the bits, and add 1, resulting in `11101111`.

**Secondary Storage**: Includes Optical (CDs), Magnetic (hard drives), and Solid State (SSDs), each using specific methods (e.g., electromagnets, floating gates) for storing data.

**RAM vs ROM**: RAM is volatile and stores active data, while ROM is non-volatile and stores bootloader data.

**Serial Half-Duplex Transmission**: Sends data one bit at a time over a single wire, allowing for longer-distance communication but at slower speeds.

**Sensors**: Used to automate systems and gather data like temperature and humidity for applications in various fields like climate control and security.

**Web Page Access**: DNS servers resolve URLs to IP addresses, and browsers render the data to display web pages.

**Upgrading CPUs**: Improving performance by increasing clock speed, adding cores, and expanding cache size.
