If you are preparing for the Punjab Board Class 10 Computer Science and Entrepreneurship Annual Examination 2027, these Chapter 1 (1.1 Introduction to Operating System) MCQs are an excellent resource for revision. The questions are prepared according to the New Computer Science and Entrepreneurship Syllabus 2026 and cover the most important concepts frequently asked in board examinations. Practice these multiple-choice questions to strengthen your understanding and score higher marks.
1.1 Introduction to Operating System (OS)
Operating System (OS) is a type of system software that manages hardware, runs application software, and provides a user interface like Windows, macOS, Linux, Android, and iOS, along with their basic roles. Here we will go a step further and focus on how the operating system works as the central controller of the computer system, ensuring smooth and secure interaction between the user and the hardware, especially in multi-user environments.
1.1.1 Operating System (OS) as the Central System Controller
An operating system works like a traffic controller for the computer. It decides which task should be done first, how the computer’s memory is used, and which devices (like a printer or speakers) should be active at a given time. In short, we can say that the OS makes sure the computer works smoothly even when multiple tasks are running at the same time.
1.1.2 Role in User-Hardware Interaction
Computer hardware cannot understand human language directly. The operating system acts as a translator between the user and the hardware system.
Example: When you click an icon or type something, the OS changes those actions into instructions that the hardware can understand. This allows people to use computers easily without learning how the hardware works.
1.1.3 Responsibilities in Multi-User Environments Tasks
In places like schools, offices, or online systems, many people may use the same computer. The operating system ensures:
1. The creation and management of separate user accounts.
2. Keeps each user’s files and information private.
3. Shares the computer’s resources fairly so that no one slows down the systems functionalities.
4. Protect shared resources from unauthorized access.
1.1.4 Creating and Managing User Accounts
The operating system allows separate accounts for different users, each with its own desktop, files, settings, and passwords.
Example: In computer lab, students login with a username and password provided by the school. This keeps each student’s work separate and private.
In most modern OS like Windows, a new account can be created through the Settings or Control Panel by selecting User Accounts, choosing Add New User, and entering details like username, password, and account type(Standard, Administrative, Guest).
