Q107. What does the abbreviation OSI stand for in computer networking?
a) Open System Interconnection
b) Open-Source Interconnection
c) Open Software Interconnection
d) Open System Interface
Show Answer
Correct Answer: a) Open System Interconnection
Explanation: OSI (Open System Interconnection) is a reference model for how applications communicate over a network. The OSI model divides the functions of a network protocol into a series of seven layers, each of which performs a specific function in the process of transmitting data between networked devices. The OSI model is widely used as a framework for understanding and designing network protocols.
Q108. What does the abbreviation OOP stand for in computer programming?
a) Object Oriented Programming
b) Object Oriented Processing
c) Object Oriented Protocol
d) Object Oriented Project
Show Answer
Correct Answer: a) Object Oriented Programming
Explanation: OOP (Object Oriented Programming) is a programming paradigm that uses objects, which are instances of classes, to represent and manipulate data. OOP emphasizes the use of objects and their interactions, rather than focusing on functions and data manipulation. This approach promotes modularity, reusability, and maintainability in software development. Examples of object-oriented programming languages include Java, C++, and Python.
Q109. What does the abbreviation OFDM stand for in wireless communication?
a) Orthogonal Frequency Division Multiplexing
b) Orthogonal Frequency Division Modulation
c) Orthogonal Frequency Data Multiplexing
d) Orthogonal Frequency Data Modulation
Show Answer
Correct Answer: a) Orthogonal Frequency Division Multiplexing
Explanation: OFDM (Orthogonal Frequency Division Multiplexing) is a digital modulation technique used in wireless communication systems to transmit data over multiple carrier frequencies. OFDM divides the available bandwidth into multiple, closely spaced subcarriers, each carrying a portion of the data. This approach increases the efficiency of data transmission and reduces the effects of interference and signal fading. OFDM is used in various wireless communication standards, such as Wi-Fi, LTE, and digital television broadcasting.
Q110. What does the abbreviation OCR stand for in computer technology?
a) Optical Character Reader
b) Optical Code Reader
c) Optical Character Recognition
d) Optical Code Recognition
Show Answer
Correct Answer: c) Optical Character Recognition
Explanation: OCR (Optical Character Recognition) is a technology that converts printed or handwritten text into machine-encoded text. OCR software can recognize characters in scanned documents, photographs, or other images and convert them into editable and searchable digital text.
