Python is renowned for its clear syntax and readability, making it a popular choice for beginners and in educational settings. Other languages like C++ and Java are more complex, while Assembly is low-level and less accessible for beginners.
What does the term 'software' refer to in computer systems?
Networks and communication devices
Storage devices like hard drives
Programs and applications
Physical components of the computer
Software consists of the programs and applications that instruct a computer on how to perform tasks. This is distinct from hardware, which are the tangible components of a computer system.
Which of the following is an example of non-volatile memory?
RAM
Cache memory
Registers
Hard disk drive
Non-volatile memory retains data even after the computer is turned off. A hard disk drive is a typical example of non-volatile memory, unlike volatile memory types such as RAM or cache.
Which option best defines the Internet?
A global network connecting millions of computers
A single website
A personal computer in an office
A program used for creating documents
The Internet is a vast, global network that connects millions of computers worldwide, allowing for communication and data exchange. It is not represented by a single computer, website, or standalone program.
Which device directs data between different networks?
Modem
Switch
Hub
Router
A router is responsible for directing data packets between different networks, ensuring that information reaches its intended destination. Although switches and hubs work within local networks, they do not perform the inter-network routing function.
In email communication, what does 'CC' stand for?
Carbon Copy
Central Copy
Controlled Copy
Correlated Copy
The term 'CC' in email stands for Carbon Copy, which is used to send an identical copy of the email to additional recipients. This feature helps keep other parties informed without making them the primary recipient.
Which application is best suited for creating and editing text documents?
Spreadsheet
Word processor
Database
Presentation software
A word processor is designed specifically for creating, editing, and formatting text documents. The other applications serve different functions such as numerical analysis, data management, or creating visual slideshows.
What is the primary function of an antivirus program?
To manage user passwords
To detect and remove malware
To increase system speed
To backup files automatically
An antivirus program is designed to detect, quarantine, and remove malicious software from a computer system. Its primary role is to protect the system from malware, rather than optimizing performance or managing passwords.
What is the main difference between RAM and ROM in a computer system?
Both RAM and ROM are volatile, but ROM is faster
RAM is used solely for graphics processing while ROM handles system instructions
RAM permanently stores data, while ROM is only for temporary data
RAM is volatile and loses data when power is off, whereas ROM retains data
RAM (Random Access Memory) is volatile, meaning it loses its stored data when the computer is turned off, while ROM (Read-Only Memory) is non-volatile and retains crucial data permanently. This distinction is fundamental in understanding computer memory.
Which of the following best describes 'open source' software?
Software created exclusively for government use
Software with source code made publicly available for modification and distribution
Software that is only available through paid licenses
Software that can only run on one specific device
Open source software provides users and developers with access to its source code, allowing modification and redistribution. This promotes collaboration and transparency, distinguishing it from proprietary software.
What does the term 'protocol' refer to in the context of computer networks?
A software application for editing documents
A set of rules that govern data communication between devices
A method for repairing computer hardware
A device used to connect a computer to the internet
A protocol is a standardized set of rules that defines how data is transmitted and received across networks. It ensures effective communication between different devices in a network.
How does encryption enhance computer security?
It converts data into a code to prevent unauthorized access
It creates random advertisements on the screen
It deletes old files to free up space
It speeds up data processing by using complex algorithms
Encryption transforms readable data into an unreadable format that can only be decoded with the correct key. This process helps protect sensitive information from unauthorized access.
What does the binary system in computing represent?
A computer network protocol
A numeral system that uses only two digits: 0 and 1
A system that uses decimal numbers for calculations
A programming language used for database management
The binary system is a base-2 numeral system that uses only the digits 0 and 1. This system is fundamental to digital computing and data representation.
