Q4. Integrated Chipsor IC’s were started to be in use from which generation of Computers?
Sol. IC were startedto be in use from 3rd generation of computers. In third generation of computer,IC (Integrated circuits) was used as the electronic component for computers.The development of IC gave birth to a new field of microelectronics. The mainadvantage of IC is not only its small size but its superior performance andreliability than the previous circuits. It was first developed by T.S Kilby.This generation of computer has huge storage capacity and higher calculatingspeed.
Q5. In Computerprogramming there is set of subroutine definitions, protocols, and tools forbuilding software and applications. Which among the following is a term forsets of requirements that govern how one application can talk to another?
Sol. An API may befor a web-based system, operating system, database system, computer hardware,or software library. It is an acronym for Application Programming Interface. AnAPI specifies how software components should interact and APIs are used whenprogramming graphical user interface (GUI) components.
Q6. BSoDs can becaused by poorly written device drivers or malfunctioning hardware, such asfaulty memory, power supply issues, overheating of components, or hardware runningbeyond its specification limits. Which color screen is displayed whenencountered a BSOD Error?
Sol. BSODs appearwhen Microsoft Windows encounters a critical error it can’t recover from, requiringa reboot and possibly resulting in lost work. It stands for blue screen ofdeath. Blue screens are generally caused by problems with your computer’shardware or issues with its hardware driver software. A blue screen occurs whenWindows encounters a “STOP Error.” This critical failure causes Windows tocrash and stop working

Q9. There is anetwork that can connect networks ranging from small location or area to abigger range including public packet network and large corporate networks. Thatnetwork’s enterprise allows users to share access to applications, services andother centrally located resources. Its ability for a huge geographical accesshas transformed networking. Which among the following is that network?
Sol. WAN stands forWide Area Network. A wide area network (WAN) is a geographically distributedprivate telecommunications network that interconnects multiple local areanetworks (LANs). In an enterprise, a WAN may consist of connections to acompany’s headquarters, branch offices, colocation facilities, cloud servicesand other facilities.
Q10. Which among thefollowing is not an Object Oriented Programming Language?
Sol. Pascal is animperative and procedural programming language, designed in 1968/1969 andpublished in 1970 by Niklaus Wirth as a small and efficient language intendedto encourage good programming practices using structured programming and datastructuring.
Q11. Which cloud is acloud computing environment that uses a mix of on-premises, private cloud andthird-party, public cloud services with orchestration between the two platformsand it is particularly valuable for dynamic or highly changeable workloads?
(a) Dynamic Cloud
(b) Advance Cloud
(c) Hybrid Cloud
(d) Sharing Cloud
Sol. Hybrid cloud isa cloud computing environment which uses a mix of on-premises, private cloudand third-party, public cloud services with orchestration between the twoplatforms. By using a Hybrid approach, companies can maintain control of aninternally managed private cloud while relying on the public cloud as needed.
