Previous Year SSC Computer Awareness MCQ Set- 20
191. Which language is used to write code for Web pages?
A. JavaScript
B. Python
C. Hypertext Markup Language (HTML)
D. C++
Answer – Answer: C. Hypertext Markup Language (HTML)
Explanation- HTML is the standard language used to create web pages. It is a markup language that defines the structure and layout of a web page using various tags and attributes. JavaScript is a programming language used to add interactivity and dynamic behavior to web pages. Python is a high-level programming language used for various purposes such as web development, scientific computing, and data analysis. C++ is a programming language used for system programming, game development, and other applications where high performance is required.
192. What language were the first computers programmed with?
A. Machine language
B. Assembly language
C. High-level language
D. Python
Answer – A. Machine language
Explanation- The first computers were programmed using machine language, which is the lowest-level programming language. Machine language consists of binary code that can be executed directly by the computer’s hardware. Assembly language is a low-level programming language that uses mnemonics to represent machine instructions. High-level programming languages, such as Python and C++, were developed later to make programming easier and more accessible to programmers.
193. What is a filename?
A. A name given to a folder
B. A name given to an operating system
C. A name given to a computer program
D. A unique name given to a file of information
Answer – D. A unique name given to a file of information
Explanation- A filename is a unique name given to a file of information stored on a computer’s hard drive. It is used to identify and locate a specific file on the computer. A folder is a container for files and other folders, and it can also have a name. An operating system is a system software that manages computer hardware and software resources. A computer program is a set of instructions that perform a specific task.
194. What is data or instruction entered into the memory of a computer considered as?
A. Processing
B. Output
C. Input
D. Storage
Answer – D. Storage
Explanation- Data or instructions entered into the memory of a computer are considered as storage. There are different types of computer memory, such as primary memory (RAM), secondary memory (hard drive, solid-state drive), and tertiary memory (optical disks, magnetic tapes). Processing refers to the manipulation of data or instructions by a computer’s central processing unit (CPU) to produce a result. Output refers to the information produced by a computer as a result of processing input. Input refers to the data or instructions entered into a computer’s memory.
195. What part of the computer displays the work done?
A. Keyboard
B. CPU
C. Printer
D. Monitor
Answer – D. Monitor
Explanation- The monitor, also known as a display screen, is the part of the computer that displays the work done. It allows the user to see the output produced by the computer, such as text, images, and videos. The keyboard is an input device used to enter data and commands into the computer. The CPU is the brain of the computer that performs calculations and logical operations. The printer is an output device that produces a physical copy of the output produced by the computer.
196. What is a series of instructions that tells a computer what to do and how to do it?
A. Software
B. Hardware
C. Input
D. Program
Answer – D. Program
Explanation- A program is a series of instructions that tells a computer what to do and how to do it. It can be written in various programming languages and executed by the computer’s CPU (Central Processing Unit) to perform specific tasks.
197. What is hardware?
A. The part of a computer that one can touch and feel
B. The part of a computer that stores data and programs
C. The part of a computer that performs calculations and logical operations
D. The part of a computer that communicates with other computers
Answer – A. The part of a computer that one can touch and feel
Explanation- Hardware refers to the physical components of a computer system that can be touched and felt, such as the keyboard, monitor, CPU, memory, hard drive, and other peripheral devices. It is the opposite of software, which refers to the intangible programs and data that are stored and processed by the computer.
198. What is the role of a computer sales representative?
A. To create computer hardware and software
B. To repair computer hardware and software
C. To determine a buyer’s needs and match it to the correct hardware and software
D. To program computers
Answer – C. To determine a buyer’s needs and match it to the correct hardware and software
Explanation- The role of a computer sales representative is to understand the needs and requirements of the buyer and recommend the appropriate hardware and software solutions that can meet those needs. This involves assessing the buyer’s budget, usage requirements, and other factors to suggest the most suitable options.
199. What do supercomputers refer to?
A. The smallest and cheapest computers
B. The most common computers used in households
C. The fastest, biggest, and most expensive computers
D. Computers used only by scientists and researchers
Answer – C. The fastest, biggest, and most expensive computers
Explanation- Supercomputers are high-performance computing systems that are designed to handle large and complex computational tasks. They are used in various fields such as scientific research, weather forecasting, financial modeling, and cryptography. Supercomputers are typically the fastest, most powerful, and expensive computers available, and they can perform trillions of calculations per second.
200. What is executing?
A. The process of carrying out commands
B. The process of creating commands
C. The process of storing commands
D. The process of deleting commands
Answer: A. The process of carrying out commands
Answer – A. The process of carrying out commands
Explanation- Executing refers to the process of carrying out or performing the commands or instructions that are specified in a program. Once a program is compiled or interpreted by the computer, its instructions are executed in the sequence specified by the program’s logic, and the desired output or result is produced.
