Sol. Ctrl+F is the short cut key combination that can be used to search in Windows Explorer.

S10. Ans.(d)
Sol. The very first device that had fundamentally the same functionality as a router does today was the Interface Message Processor (IMP); IMPs were the devices that made up the ARPANET, the first TCP/IP network.

S11. Ans.(a)
Sol. First Generation computers are characterized by the use of vacuum tubes. These vacuum tubes were used for calculation as well as storage and control. Later, magnetic tapes and magnetic drums were implemented as storage media. The first vacuum tube computer, ENIAC, was developed by US army ordinance to calculate ballistic firing tables in WWII. It had about 17 000 vacuum tubes.
