Q31. What does QBE stand for in the context of databases?
a) Query By Example
b) Quick Byte Element
c) Query Byte Element
d) Quick Binary Execution
Show Answer
Correct Answer: a) Query By Example
Explanation: QBE stands for Query By Example. It is a database query language that allows users to search for information by providing an example of the data they are looking for. QBE is designed to be more intuitive and user-friendly than traditional query languages like SQL, making it easier for non-technical users to retrieve data from databases.
Q32. What does QIC stand for in the context of data storage?
a) Quick Implementation Capability
b) Quarter Inch Cartridge
c) Quality in Care
d) Qualified Independent Contractor
Show Answer
Correct Answer: b) Quarter Inch Cartridge
Explanation: QIC stands for Quarter Inch Cartridge. It is a magnetic tape data storage format that was widely used for backup and archiving purposes in the 1980s and 1990s. QIC tapes are 0.25 inches wide and come in various lengths and capacities, allowing for the storage of large amounts of data in a compact and portable format.
Q33. What does ROM stand for in the context of computer memory?
a) Read Only Memory
b) Random Operation Memory
c) Restricted Operation Memory
d) Reusable Object Memory
Show Answer
Correct Answer: a) Read Only Memory
Explanation: ROM stands for Read Only Memory. It is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified, making it suitable for storing firmware and other data that does not need to be changed frequently.
Q34. What does RISC stand for in the context of computer architecture?
a) Reduced Instruction Set Computer
b) Random Instruction Set Computer
c) Restricted Instruction Set Computer
d) Reconfigurable Instruction Set Computer
Show Answer
Correct Answer: a) Reduced Instruction Set Computer
Explanation: RISC stands for Reduced Instruction Set Computer. It is a computer architecture designed to simplify the individual instructions given to the computer, allowing for faster execution and more efficient use of resources. RISC architectures focus on using a small set of simple instructions to perform computing tasks, in contrast to CISC (Complex Instruction Set Computer) architectures, which use a larger set of more complex instructions.
Q35. What does RAM stand for in the context of computer memory?
a) Random Access Memory
b) Read Access Memory
c) Restricted Access Memory
d) Reusable Access Memory
Show Answer
Correct Answer: a) Random Access Memory
Explanation: RAM stands for Random Access Memory. It is a type of volatile memory that temporarily stores data while a computer is running. RAM allows for quick access to data and enables efficient multitasking, as it can be read and written to at high speeds. When the computer is turned off, the data stored in RAM is lost.
Q36. What does RARP stand for in the context of networking?
a) Reverse Address Resolution Protocol
b) Restricted Address Resolution Protocol
c) Random Address Resolution Protocol
d) Reconfigurable Address Resolution Protocol
Show Answer
Correct Answer: a) Reverse Address Resolution Protocol
Explanation: RARP stands for Reverse Address Resolution Protocol. It is a network protocol used to obtain the IP address of a device from its known MAC address. RARP is typically used by diskless workstations and other network devices that do not have a permanent IP address assigned to them.
Q37. What does RDBMS stand for in the context of databases?
a) Relational Data Base Management System
b) Restricted Data Base Management System
c) Random Data Base Management System
d) Reconfigurable Data Base Management System
Show Answer
Correct Answer: a) Relational Data Base Management System
Explanation: RDBMS stands for Relational Data Base Management System. It is a type of database management system that organizes data into tables with rows and columns, allowing for efficient storage, retrieval, and manipulation of data. RDBMSs use Structured Query Language (SQL) to perform operations on the data and enforce data integrity constraints.
Q38. What does RAID stand for in the context of data storage?
a) Redundant Array of Inexpensive Disks
b) Random Array of Inexpensive Disks
c) Restricted Array of Inexpensive Disks
d) Reconfigurable Array of Inexpensive Disks
Show Answer
Correct Answer: a) Redundant Array of Inexpensive Disks
Explanation: RAID stands for Redundant Array of Inexpensive Disks. It is a data storage technology that combines multiple physical disk drives into a single logical unit for the purposes of data redundancy, performance improvement, or both. RAID can be implemented using various levels, each with different trade-offs between performance, capacity, and fault tolerance.
Q39. What does RGB stand for in the context of digital images?
a) Red Green and Blue
b) Random Green and Blue
c) Restricted Green and Blue
d) Reconfigurable Green and Blue
Show Answer
Correct Answer: a) Red Green and Blue
Explanation: RGB stands for Red Green and Blue. It is a color model used in digital imaging and computer graphics to represent colors as a combination of the three primary colors: red, green, and blue. By varying the intensity of each primary color, a wide range of colors can be produced.
