Free BSGS Computer Studies Question and Answer — Questions and Answers
Question 1: The region of the motherboard designated as temporary computer memory is known as .
- RAM (Correct answer)
- Math co-processor
- ROM BIOS
- Expansion slot
Correct answer: RAM
RAM, or Random Access Memory, is the primary temporary storage area for data and programs currently being used by the CPU. It is volatile memory, meaning its contents are lost when the computer is turned off. RAM allows for quick read and write access, enabling the computer to perform tasks efficiently.
Question 2: The tool that performs the conversion of analog to digital signals in a data communication network is known as the .
- Modem (Correct answer)
- Front end processfor
- Multiplexer
- Decoder.
Correct answer: Modem
A modem (modulator-demodulator) is a device that converts analog signals into digital signals (demodulation) and digital signals into analog signals (modulation). This conversion is essential for transmitting digital information over analog transmission mediums, such as telephone lines or cable networks, allowing computers to communicate over long distances.
Question 3: What service listed below DOES NOT exist on the internet?
- Electronic mail
- World Wide Web
- Chat room
- Off line shopping (Correct answer)
Correct answer: Off line shopping
The internet provides various online services like electronic mail, the World Wide Web for browsing, and chat rooms for communication. "Off line shopping" refers to shopping in physical stores without an internet connection, which is a traditional method of commerce and not an internet service itself.
Question 4: Software that was downloaded without a license is referred to be .
- Duplicated
- Pirated (Correct answer)
- Shared
- Original software
Correct answer: Pirated
Pirated software refers to copyrighted software that has been illegally copied, distributed, or used without proper authorization or a valid license from the copyright holder. This practice violates intellectual property laws and can lead to legal penalties. It deprives software developers of their rightful revenue.
Question 5: We can employ ________ to increase computer security.
- ID numbers
- Passwords (Correct answer)
- Account number
- User names
Correct answer: Passwords
Passwords are a fundamental security measure used to restrict unauthorized access to computer systems, accounts, and data. By requiring users to enter a secret string of characters, passwords verify identity and ensure that only authorized individuals can access protected resources. Strong passwords significantly enhance overall computer security.
Question 6: A byte is made up of:
- 8 bits (Correct answer)
- 1 bit
- 0 or 1 bit
- 0 bit
Correct answer: 8 bits
In computing, a byte is a unit of digital information that most commonly consists of eight bits. A bit is the smallest unit of data, representing a binary value of either 0 or 1. A byte is typically used to encode a single character of text, making it a fundamental building block for storing and processing data.
Question 7: Identify the printer that prints exceptionally quickly.
- Dot-matrix
- Ink-jet printer
- Laser printer (Correct answer)
- Plotter
Correct answer: Laser printer
Laser printers are known for their high printing speed and excellent print quality, especially for text and graphics. They use a laser beam to project an image onto a photosensitive drum, which then attracts toner particles. This process allows them to print pages much faster than inkjet or dot-matrix printers, making them ideal for high-volume printing.
Question 8: Another name for a RAM is:
- Working memory
- Working memory
- Random Access Memory (Correct answer)
- All of the above
Correct answer: Random Access Memory
RAM is an acronym for Random Access Memory. It is a type of computer memory that can be accessed randomly, meaning any byte of memory can be accessed without touching preceding bytes. This allows for very fast data retrieval, making it crucial for the computer's active operations.
Question 9: What makes up the CPU is:
- The ALU only
- ALU and CU (Correct answer)
- Programs only
- The CU only
Correct answer: ALU and CU
The Central Processing Unit (CPU) is composed of two main parts: the Arithmetic Logic Unit (ALU) and the Control Unit (CU). The ALU performs all arithmetic and logical operations, while the CU manages and coordinates all the components of the computer, fetching instructions, decoding them, and directing the flow of data.
Question 10: A computer program may also be referred to as:
- Peripheral
- Input-output
- Hardware
- Software (Correct answer)
Correct answer: Software
Software refers to the set of instructions, data, or programs used to operate computers and execute specific tasks. It is the intangible component of a computer system, in contrast to hardware, which is the physical components. Computer programs are a type of software designed to perform particular functions.
Question 11: A ______________ is an electronic device that enables the input, processing, and output of information.
- Motherboard
- Computer (Correct answer)
- CPU
- Operating system
Correct answer: Computer
A computer is an electronic device designed to accept data (input), process it according to a set of instructions, and produce results (output). It can store and retrieve information, perform calculations, and execute various tasks. This definition encompasses its core functions in handling information.
Question 12: A global network of computers is called .
- Internet (Correct answer)
- Network
- CPU
- RAM
Correct answer: Internet
The Internet is a vast, global network of interconnected computer networks that uses standard communication protocols to link billions of devices worldwide. It enables users to share information, communicate, and access a wide range of services. It is the largest and most widely used computer network.
Question 13: Give the name of the component in the computer that handles calculations, data movement, and processing.
- Motherboard
- CPU (Correct answer)
- RAM
- Hard Drive
Correct answer: CPU
The Central Processing Unit (CPU) is often referred to as the "brain" of the computer. It is responsible for executing instructions, performing arithmetic and logical operations, and managing the flow of data throughout the system. All major calculations and data processing tasks are handled by the CPU.
Question 14: The component of a computer that enables a user to input data is referred to as .
- Software
- Input Device (Correct answer)
- Operating system
- Output Device
Correct answer: Input Device
An input device is any peripheral used to provide data and control signals to an information processing system, such as a computer. Examples include keyboards, mice, microphones, and scanners. These devices allow users to interact with the computer and feed it information.
Question 15: A folder, program, or other item represented by a little picture is referred to as a .
- Image
- Desktop
- Desktop
- Icon (Correct answer)
Correct answer: Icon
An icon is a small graphical representation of a program, file, function, or website on a computer screen. Icons provide a visual shortcut for users to quickly identify and access specific items without needing to know their full names or locations. They are a key element of graphical user interfaces (GUIs).
Question 16: What is the name of the short-term memory that a computer loses when it is shut off?
- RAM (Correct answer)
- Processor
- Hardware
- CPU
Correct answer: RAM
RAM (Random Access Memory) is a type of volatile memory that temporarily stores data and programs currently in use by the CPU. Its contents are lost when the computer's power is turned off, which is why it's considered short-term memory. This characteristic distinguishes it from non-volatile storage like hard drives.
