[Q]: Firstly conceived and still used today for optical storage devices (CD-RW drives, DVD drives, etc.), several manufacturers offer external portable USB hard disk drives, or empty enclosures for disk drives. These offer performance comparable to internal drives, limited by the current number and types of attached USB devices, and by the upper limit of the USB interface (in practice about 30 MB/s for USB 2.0 and potentially 400 MB/s or more for USB 3.0). These external drives typically include a "translating device" that bridges between a drive's interface to a USB interface port. Functionally, the drive appears to the user much like an internal drive. Other competing standards for external drive connectivity include eSATA, ExpressCard, FireWire (IEEE 1394), and most recently Thunderbolt.
[A]: Several manufacturers offer what?


[Q]: Following the '69 season, the club posted winning records for the next few seasons, but no playoff action. After the core players of those teams started to move on, the 70s got worse for the team, and they became known as "The Loveable Losers." In 1977, the team found some life, but ultimately experienced one of its biggest collapses. The Cubs hit a high-water mark on June 28 at 47–22, boasting an 8 1⁄2 game NL East lead, as they were led by Bobby Murcer (27 Hr/89 RBI), and Rick Reuschel (20–10). However, the Philadelphia Phillies cut the lead to two by the All-star break, as the Cubs sat 19 games over .500, but they swooned late in the season, going 20–40 after July 31. The Cubs finished in 4th place at 81–81, while Philadelphia surged, finishing with 101 wins. The following two seasons also saw the Cubs get off to a fast start, as the team rallied to over 10 games above .500 well into both seasons, only to again wear down and play poorly later on, and ultimately settling back to mediocrity. This trait became known as the "June Swoon." Again, the Cubs' unusually high number of day games is often pointed to as one reason for the team's inconsistent late season play.
[A]: During what decade did the Cubs become known as "The Loveable Losers"?


[Q]: Waste management including sewage treatment, the linked processes of deforestation and soil degradation, and climate change or global warming are the major environmental problems in Nigeria. Waste management presents problems in a mega city like Lagos and other major Nigerian cities which are linked with economic development, population growth and the inability of municipal councils to manage the resulting rise in industrial and domestic waste. This huge waste management problem is also attributable to unsustainable environmental management lifestyles of Kubwa Community in the Federal Capital Territory, where there are habits of indiscriminate disposal of waste, dumping of waste along or into the canals, sewerage systems that are channels for water flows, etc.
[A]:
What is the largest Nigerian city?
