कंप्यूटर अवेयरनेस टेस्ट - 26

 Ans.(a)

Sol. F2 is a shortcut to rename selected object in MS windows 8 and higher versions

 Ans.(c)

Sol. IC were started to be in use from 3^rd 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 main advantage of IC is not only its small size but its superior performance and reliability than the previous circuits. It was first developed by T.S Kilby. This generation of computer has huge storage capacity and higher calculating speed

Ans.(d)

Sol. BSODs appear when Microsoft Windows encounters a critical error it can’t recover from, requiring a reboot and possibly resulting in lost work. It stands for blue screen of death. Blue screens are generally caused by problems with your computer’s hardware or issues with its hardware driver software. A blue screen occurs when Windows encounters a “STOP Error.” This critical failure causes Windows to crash and stop working

 Ans (e)

Sol. Walter Houser Brattain was an American physicist, along with John Bardeen and William Shockley, invented the point-contact transistor.

 Ans (a)

Sol. Diamond shaped figure is used to represent relationship in E-R diagram.

Ans (d)

Sol. Updating is periodically adding, changing and deleting file records

Ans (c)

Sol. A gutter margin setting adds extra space to the side margin or top margin of a document that you plan to bind. A gutter margin helps ensure that text isn't obscured by the binding.

Ans (a)

Sol. A codec is a device or computer program for encoding or decoding a digital data stream or signal

 Ans (d)

Sol. General purpose computers can perform all those tasks

Ans (b)

Sol. Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers

 Ans.(a)

Sol. Personal Digital Assistant (PDA) is a device with functioning of a mobile information manager.

Ans.(c)

Sol. IEEE 802 is a family of IEEE standards dealing with local area networks and metropolitan area networks. 802.3 is for Ethernet.

Ans.(c)

Sol. Byte is a 8-bit binary number and the biggest number you can get from a byte is 255(decimal)- 1111 1111 (binary).

 Ans.(b)

Sol. Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. The tags contain electronically stored information. Passive tags collect energy from a nearby RFID reader's interrogating radio waves.

Ans.(b)

Sol. Binary language (number system) has 2 digits- 0 and 1.

Ans.(b)

Sol. Microsoft Edge is a web browser developed by Microsoft and included in Windows 10, Windows 10 Mobile.

 Ans.(b)

Sol. Algorithm is a self-contained step-by-step set of operations.

Ans.(d)

Sol. Remote Desktop Services (RDS), known as Terminal Services in Windows Server 2008 and earlier, is one of the components of Microsoft Windows that allows a user to take control of a remote computer or virtual machine over a network connection.

Ans.(d)

Sol. Simplex is unidirectional while half duplex and full duplex communication modes are bidirectional. Difference between half duplex and full duplex is that the transmission of data is done one at a time in half duplex while simultaneous data transmission takes place in full duplex communication.

Ans.(d)

Sol. Since static and dynamic images, high graphics, voice notes and songs are rich in properties, they occupy a lot of memory in the storage system of the computer.

Ans.(b)

Sol. Input devices are hardware components that allow you to enter data and instructions into a computer system.

Ans.(c)

Sol. HDMI is the most common one for connecting to TVs and also appears on many external monitors and projectors. Other ports for this purpose are DVI (Digital Visual Interface) and Display Port. Earlier there were VGA ports  (Video Graphics Array) .

Ans.(d)

Sol. A motherboard is a part of the computer hardware that compensates the difference between the speeds of CPU and peripherals.

Ans.(c)

Sol. RAM is a hardware component that helps to start a computer system by booting, as it contains the startup instructions.

 Ans.(a)

Sol. A motherboard is that part of a CPU which coordinates all the activities of a computer system. Various types of hardware are attached on the motherboard to facilitate these activities. 

 Ans.(c)

Sol. A floppy disc is a storage device that has a very small storage capacity of only 1.44 MB. Due to small storage capacity and proneness to frequent damages floppy discs vanished from the market. 

Ans.(d)

Sol. CDs and DVDs are used to write data on them. Even though compact, these devices can easily carry large volumes of data. They are Optical storage devices.

 Ans.(d)

Sol. In a computer system, there are only three types of languages to perform different types of work on the computer, which are high level, low-level, and machine languages.

 Ans.(a)

Sol. Hertz is a unit in which the speed of clock frequency of a microprocessor is measured.

 Ans.(c)

Sol. A flash drive is plugged into a USB port.
