Some people worry that artificial intelligence will make us feel inferior, but then, anybody in his right mind should have an inferiority complex every time he looks at a flower.

Tech Word
Stands for "Small Computer System Interface," and is pronounced "scuzzy." SCSI is a computer interface used primarily for high-speed hard drives. This is because SCSI can support faster data transfer rates than the commonly used IDE storage interface. SCSI also supports daisy-chaining devices, which means several SCSI hard drives can be connected to single a SCSI interface, with little to no decrease in performance.The different types of SCSI interfaces are listed below:
- SCSI-1: Uses an 8-bit bus, supports data transfer speeds of 4 MBps.
- SCSI-2: Uses a 50-pin connector instead of a 25-pin connector, and supports multiple devices. It is one of the most commonly used SCSI standards. Data transfer speeds are typically around 5 MBps.
- Wide SCSI: Uses a wider cable (168 cable lines to 68 pins) to support 16-bit data transfers.
- Fast SCSI: Uses an 8-bit bus, but doubles the clock rate to support data transfer speeds of 10 MBps.
- Fast Wide SCSI: Uses a 16-bit bus and supports data transfer speeds of 20 MBps.
- Ultra SCSI: Uses an 8-bit bus, supports data rates of 20 MBps.
- SCSI-3: Uses a 16-bit bus, supports data rates of 40 MBps. Also called Ultra Wide SCSI.
- Ultra2 SCSI: Uses an 8-bit bus, supports data transfer speeds of 40 MBps.
- Wide Ultra2 SCSI: Uses a 16-bit bus, supports data transfer speeds of 80 MBps.
- Ultra3 SCSI: Uses a 16-bit bus, supports data transfer rates of 160 MBps. Also known as Ultra-160.
- Ultra-320 SCSI: Uses a 16-bit bus, supports data transfer speeds of 320 MBps.
- Ultra-640 SCSI: Uses a 16-bit bus, supports data transfer speeds of 640 MBps.
While SCSI is still used for some high-performance equipment, newer interfaces have largely replaced SCSI in certain applications. For example, Firewire and USB 2.0 have become commonly used for connecting external hard drives. Serial ATA, or SATA, is now used as a fast interface for internal hard drives.

Tech Jokes
Junior engineer, a Design engineer and their Project Manager are on their way to a meeting. On their way through a park, they come across a wonder lamp. They rub the lamp and a ghost appears. The ghost says, "Normally, one is granted three wishes but as you are three, I will allow one wish each". So the eager Junior Software engineer shouted, I want the first wish. I want to be in the Bahamas,on a fast boat and have no worries. "Pfufffff"and he was gone.Now the Senior Software engineer could not keep quiet and shouted " I want to be in Florida with beautiful girls, plenty of food and cocktails. "Pfufffff"and he was also gone.The Project Manager calmly said," I want these two idiots back in the office after lunch at 1.30pm" Moral of the story is: "Always allow the boss to speak first"
