Category Description: Computers: A Brief Overview A computer is an electronic device capable of processing data according to instructions given to it. This processing involves inputting data, storing it, manipulating it, and producing output. Key Components: * Hardware: The physical components of a computer, including the central processing unit (CPU), memory, storage devices, input/output devices, and peripherals. * Software: The intangible programs and applications that instruct the hardware to perform specific tasks. This includes operating systems, software applications, and programming languages. How Computers Work: * Input: Data is entered into the computer through devices like keyboards, mice, scanners, or digital cameras. * Processing: The CPU interprets and executes instructions from software, performing calculations and making decisions. * Storage: Data is saved on storage devices such as hard drives, solid-state drives, or external drives for later use. * Output: Processed data is displayed on monitors, printed on paper, or sent to other devices as output. Types of Computers: * Personal Computers (PCs): Desktop and laptop computers for individual use. * Servers: Powerful computers that manage networks and share resources. * Supercomputers: Extremely powerful computers used for complex calculations and simulations. * Mainframes: Large computers capable of handling massive amounts of data. * Embedded Computers: Computers integrated into other devices like smartphones, cars, and appliances. Impact of Computers: Computers have revolutionized society, transforming industries, education, communication, and entertainment. They have increased efficiency, accuracy, and speed in various fields. However, their widespread use also raises concerns about privacy, security, and dependence. Computers continue to evolve rapidly, with advancements in artificial intelligence, quantum computing, and other technologies promising to shape the future.

Q2. Which of the following monitor looks like a television and are normally used with non-portable computer systems?
Q2. Which of the following monitor looks like a television and are normally used with non-portable computer systems?

(A) LED monitor
(A) LED monitor
(B) LCD monitor
(B) LCD monitor
(C) CRT monitor
(C) CRT monitor
(D) OLED monitor
(D) OLED monitor
Answer: (C) CRT monitor
Answer: (C) CRT monitor
A CRT (Cathode Ray Tube) monitor is a type of display technology that was widely used in older computer systems and televisions. They are characterized by their bulky, heavy design, which resembles traditional TV sets. These monitors use an electron gun to project a beam onto a phosphorescent screen, creating images. Due to their size and weight, CRT monitors are typically used with non-portable computer systems (desktops) and are not suitable for laptops or other mobile devices. Modern display technologies like LCD, LED, and OLED monitors are much thinner, lighter, and more energy-efficient.

(A) Commonly Oriented Machine Purposely Used for Technological and Environmental Research
(A) Commonly Oriented Machine Purposely Used for Technological and Environmental Research
(B) Commonly Oriented Machine Purposely Used for Technological and Educational Research
(B) Commonly Oriented Machine Purposely Used for Technological and Educational Research

(D) Commonly Operated Machine Purposely Used for Technological and Environmental Research
Answer: (C) Commonly Operated Machine Purposely Used for Technological and Educational Research
Answer: (C) Commonly Operated Machine Purposely Used for Technological and Educational Research
The word "COMPUTER" is not an abbreviation itself, but rather a standalone word derived from the verb "compute." While some informal or contextual shortenings like "comp" might be used, there is no universally recognized or official abbreviation for "COMPUTER" in the same way that there are for terms like "e.g." or "Dr." Attempts to create an acronym for "COMPUTER" (e.g., "Common Operating Machine Purposely Used for Technical and Educational Research") are generally considered backronyms and not the origin or a true abbreviation of the word.

(A) HTML
(A) HTML
(B) Python
(B) Python
(C) JavaScript
(C) JavaScript
(D) CSS
(D) CSS
Answer: (B) Python
Answer: (B) Python
HTML (HyperText Markup Language) is the foundation for structuring web content. CSS (Cascading Style Sheets) is used for styling the visual presentation. JavaScript adds interactivity and dynamic behavior. XML (Extensible Markup Language) is used for storing and transporting data, but it's not a core language for front-end web development in the same way the others are. Python is a general-purpose programming language often used for back-end development, but not typically for directly building the user interface of a website.

Q17. Which of the following language does the computer understand?
Q17. Which of the following language does the computer understand?

(A) High-level language
(A) High-level language
(B) Assembly language
(B) Assembly language
(C) Machine language
(C) Machine language
(D) Natural language
(D) Natural language
Answer: (C) Machine language
Answer: (C) Machine language
Computers fundamentally understand machine language, which is composed of binary code (sequences of 0s and 1s). Every instruction and piece of data that a computer processes must ultimately be converted into this binary format. While programmers write in high-level languages (like Python or Java) or even assembly language, these languages must be translated (compiled or interpreted) into machine language before the computer's Central Processing Unit (CPU) can execute them. Natural languages are too complex and ambiguous for direct computer understanding without sophisticated artificial intelligence processing.

(D) C
(D) C
Answer: (C) Machine Language
Answer: (C) Machine Language
Machine language is the only computer language that is directly written and understood in binary codes (sequences of 0s and 1s). It is the lowest-level programming language and is specific to the computer's architecture. Every instruction that the CPU executes is in machine code. Assembly language uses mnemonics to represent machine code instructions, making it slightly more human-readable than raw binary, but it still requires an assembler to translate it into machine code. High-level languages are much more abstract and human-readable, requiring compilers or interpreters to translate them into machine code before execution.
