Static electricity can be shocking and unexpected when exiting your car. What can you do to stop it? Television car expert Lauren Fix has more in this edition of the Car Coach.
Part of the Microprocessors glossary: Transistor-transistor logic (TTL) is a digital logic design in which bipolar transistor s act on direct-current pulses. Many TTL logic gate s are typically fabricated onto a single integrated circuit (IC). TTL ICs usually have four-digit numbers beginning with 74 or 54.
* The TTL is the number of seconds before subsequent changes to the MX record go into effect. Once the MX records are configured correctly, we recommend changing the TTL value from 3600 to 86400, which tells servers across the Internet to check every 24 hours for updates to the MX record instead of every hour.
