S2. Ans. (a)
Sol. The Antikythera mechanism is an ancient analogue computer and orrery used to predict astronomical positions and eclipses for calendrical and astrological purposes, as well as the Olympiads, the cycles of the ancient Olympic Games.
S3. Ans. (c)
Sol. MARK-1 invented was by Howard Aiken.
Sol. ENIAC was the first electronic computer in the world.
Sol. ENIAC stands for Electronic Numerical Integrator and Computer
S6. Ans. (b)
Sol. The first computer was programmed using Machine Language.
Sol. Multi-programming started in third generation.
Sol. Alpha was android version 1.0 released on 23rd September 2008. Android is continually developed by Google and the Open Handset Alliance (OHA), and has seen a number of updates to its base operating system since the initial release.
Sol. Ctrl+F is the short cut key combination that can be used to search in Windows Explorer.
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.
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.
Sol. Java Database Connectivity (JDBC) is an application programming interface (API) for the programming language Java, which defines how a client may access a database. It is part of the Java Standard Edition platform, from Oracle Corporation.
Sol. A segmentation fault is a common condition that causes programs to crash; they are often associated with a file named core. They are caused by a program trying to read or write an illegal memory location. In other words, this is a memory access violation error.
Sol. Octet is another name for a byte=8bits
Sol. Broadcast slideshow is a feature available under Slide Show Tab in PowerPoint.
