The plastic ups drive housing is what we call a floppy drive, and it's called floppy disk drive. It's a device that reads a 3.5-inch or 5.25-inch floppy disk. The most commonly used today is the 3.5-inch floppy drive, which can read and write 1.44MB of 3.5-inch floppy disk. The 5.25-inch floppy disk has been phased out and is rarely seen.

Rich Templeton, chairman, president and chief executive officer of Texas Instruments, said: “National Semiconductor has now become a strategic part of the growth of Texas Instruments' analog business. After the merger, we will focus on accelerating innovation in semiconductor business and enhancing customers. Electronic system performance and power efficiency."
National Semiconductor’s more than 5,000 employees will formally become members of Texas Instruments. The two companies will immediately work to integrate National Semiconductor into a division of Texas Instruments' analog business. At that time, Texas Instruments' analog business will have nearly 45,000 analog product portfolios, powerful customer design tools and 10 times the number of US countries. Semiconductor's original sales team.
Templeton pointed out: "The successful completion of this acquisition has enabled Texas Instruments to gain more market-leading analog products, stronger manufacturing capabilities, and the industry's largest sales and application team, thereby expanding the market advantage of Texas Instruments. After the merger, Texas Instruments will serve more customers in a wider market."
The acquisition was announced on April 4, 2011, and has now passed all necessary regulatory reviews and approved by National Semiconductor shareholders. Texas Instruments will report the third quarter earnings report released on October 24, 2011, explaining the contribution of the National Semiconductor business to the company’s financial performance.
After the formal completion of the acquisition, the analog business will account for more than 50% of the entire company's revenue.
Texas Instruments will continue to operate National Semiconductor’s manufacturing facilities in Maine, Scotland and Malaysia, and take over its headquarters and global sales and design support organization in Santa Clara. 
Floppy drive device built - in and external two. The built-in floppy drive USES the special FDD interface, while the external floppy drive is generally used for the laptop, using the USB interface.
With the development of computer, these disadvantages are gradually obvious: too small capacity, slow reading and writing speed, poor service life and reliability of floppy disk, and easy loss of data, so floppy drive has been replaced by other devices. New computers are no longer equipped with floppy drives, and personal computer users are no longer equipped with floppy drives.
