Q91. What does DNA stand for in computer terms?
a) Digital Network Architecture
b) Data Network Architecture
c) Dynamic Network Architecture
d) Distributed Network Architecture
Show Answer
Correct Answer: a) Digital Network Architecture
Explanation: In computer terms, DNA stands for Digital Network Architecture. It is a proprietary networking framework developed by Digital Equipment Corporation (DEC) in the 1970s and 1980s. DNA was designed to provide a set of communication protocols and services for DEC’s computer systems, enabling them to communicate with each other and share resources.
Q92. What is the full form of D/A in computer abbreviations?
a) Data to Analog
b) Digital to Analog
c) Disk to Analog
d) Distributed to Analog
Show Answer
Correct Answer: b) Digital to Analog
Explanation: In computer abbreviations, D/A stands for Digital to Analog. It refers to the process of converting digital signals, which are represented by discrete values (such as 0s and 1s), into analog signals, which are continuous waveforms. Digital-to-analog converters (DACs) are electronic devices that perform this conversion, allowing digital data to be processed and transmitted through analog systems.
Q93. What does DRDO stand for?
a) Data Research and Development Organization
b) Digital Research and Development Organization
c) Defence Research and Development Organization
d) Distributed Research and Development Organization
Show Answer
Correct Answer: c) Defence Research and Development Organization
Explanation: DRDO stands for Defence Research and Development Organization. It is an agency under the Ministry of Defence in India, responsible for the research and development of defense technologies and systems. DRDO was established in 1958 and has since been involved in the development of various defense-related products, including missiles, radars, electronic warfare systems, and more.
Q94. What is the full form of DPI in computer terms?
a) Data Per Inch
b) Dots Per Inch
c) Digital Per Inch
d) Disk Per Inch
Show Answer
Correct Answer: b) Dots Per Inch
Explanation: In computer terms, DPI stands for Dots Per Inch. It is a measure of the resolution of a printer, scanner, or display device, indicating the number of individual dots that can be placed within a linear inch. A higher DPI value generally corresponds to a higher level of detail and image quality.
Q95. What does DMA stand for in computer language?
a) Data Memory Access
b) Direct Memory Access
c) Digital Memory Access
d) Distributed Memory Access
Show Answer
Correct Answer: b) Direct Memory Access
Explanation: In computer language, DMA stands for Direct Memory Access. It is a feature of computer systems that allows certain hardware subsystems, such as disk drives or graphics cards, to access the main system memory directly, bypassing the central processing unit (CPU). This can improve the performance of data transfers and reduce the workload on the CPU.
Q96. What is the full form of DBS in computer terms?
a) Data Based Switching
b) Demand Based Switching
c) Digital Based Switching
d) Distributed Based Switching
Show Answer
Correct Answer: b) Demand Based Switching
Explanation: In computer terms, DBS stands for Demand Based Switching. It is a power management technique used in computer processors to dynamically adjust the operating frequency and voltage of the processor based on the current workload. This helps to reduce power consumption and heat generation when the processor is not fully utilized, improving energy efficiency and extending the life of the device.
Q97. What does DDS stand for in computer abbreviations?
a) Data Data Storage
b) Digital Data Storage
c) Dynamic Data Storage
d) Distributed Data Storage
Show Answer
Correct Answer: b) Digital Data Storage
Explanation: In computer abbreviations, DDS stands for Digital Data Storage. It is a family of magnetic tape data storage formats developed by Hewlett-Packard (HP) and IBM in the late 1980s. DDS uses helical scan technology to store data on magnetic tape, providing a cost-effective and reliable solution for long-term data storage and archiving.
Q98. What is the full form of DRAM in computer terms?
a) Data RAM
b) Digital RAM
c) Dynamic RAM
d) Distributed RAM
Show Answer
Correct Answer: c) Dynamic RAM
Explanation: In computer terms, DRAM stands for Dynamic RAM. It is a type of random-access memory that stores each bit of data in a separate capacitor within an integrated circuit. DRAM is volatile memory, meaning that it loses its data when power is removed. It is widely used in personal computers, workstations, and servers due to its relatively low cost and high storage capacity.
Q99. What does DDL stand for in computer language?
a) Data Definition Language
b) Data Description Language
c) Data Design Language
d) Data Distribution Language
Show Answer
Correct Answer: a) Data Definition Language
Explanation: DDL stands for Data Definition Language. It is a subset of SQL that deals with the creation, modification, and deletion of database structures, such as tables, indexes, and constraints. DDL statements include CREATE, ALTER, and DROP, which are used to define and manage the structure of a database.
Q100. What is the full form of DBMS in computer terms?
a) Data Based Management System
b) Data Base Management System
c) Digital Based Management System
d) Distributed Based Management System
Show Answer
Correct Answer: b) Data Base Management System
Explanation: DBMS stands for Data Base Management System. It is a set of software programs that control the storage, retrieval, and modification of organized data in a database. DBMS allows users to create, read, update, and delete data in a structured and organized manner. It also ensures data consistency, integrity, and security.
