Solutions
S1. Ans.(b)
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.
S2. Ans.(a)
Sol. Ctrl+F is the short cut key combination that can be used to search in Windows Explorer.
S3. 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.
S4. 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.
S5. Ans.(d)
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.
S6. Ans.(a)
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.
S7. Ans.(c)
Sol. Octet is another name for a byte=8bits
S8. Ans.(c)
Sol. Broadcast slideshow is a feature available under Slide Show Tab in PowerPoint.
S9. Ans.(a)
Sol. Communication between the CPU and control bus is necessary for running a proficient and functional system. Without the control bus the CPU cannot determine whether the system is receiving or sending data. It is the control bus that regulates which direction the write and read information need to go.
S10. Ans.(a)
Sol. Cache is not secondary memory.
S11. Ans.(e)
Sol. Microsoft is a cloud computing platform and infrastructure created by Microsoft for building, deploying, and managing applications and services through a global network of Microsoft-managed data centers.

S12. Ans.(d)
Sol. After a credit card transaction has been authorized by the issuing bank by sending an authorization code to the merchant, the settlement stage of the process begins. This is called batch processing because a number (or batch) of transactions is settled all at one time.
S13. Ans.(d)
Sol. Assembly language is mnemonic based low level language. Mnemonics are short codes of assembly language which chosen to remind the programmer of the instructions of binary machine-code which are apparently which are very hard to remember, write down, or correct.
S14. Ans.(e)
Sol. Tianhe-2 is China’s Supercomputer. It was the fastest until its position being taken up by SunwayTiahu Light as the Fastest Supercomputer.
S15. Ans.(b)
Sol. ALU does the arithmetic and logical operations in a computer system.
