Question 1: Computer Security Threats and Best Practices
Cybersecurity protects business data, hardware, software, networks, and users from unauthorized access, damage, theft, or misuse. In business, cybersecurity is important because companies store customer records, financial data, employee information, and operational documents digitally.
Three Types of Computer Security Threats
| Threat Type | Explanation | Business Example | Solution / Best Practice |
|---|---|---|---|
| 1. User-related threat | This happens because of human mistakes or careless behavior. Users may click phishing links, use weak passwords, or share login credentials. | An employee receives a fake bank email and enters company login details. | Train employees, use strong passwords, enable two-factor authentication, and avoid suspicious links. |
| 2. Hardware-related threat | This involves damage, theft, or failure of physical computer devices such as hard disks, servers, laptops, or USB drives. | A company laptop containing customer data is stolen. | Use device encryption, backup data regularly, lock devices physically, and use antivirus protection. |
| 3. Data-related threat | This occurs when business data is stolen, deleted, corrupted, or accessed without permission. | Hackers attack a company database and steal customer payment records. | Use access control, database encryption, regular backups, firewalls, and updated security software. |
Explanation
User-related threats are common because employees are often the weakest point in security. Phishing, social engineering, and weak passwords can allow attackers to enter business systems.
Hardware-related threats can stop business operations. If servers or storage devices fail, the organization may lose important files unless proper backup exists.
Data-related threats directly affect confidentiality, integrity, and availability of business information. Data theft can damage customer trust and create financial loss.
Conclusion
Businesses can reduce security threats by combining technology, employee awareness, strong policies, and regular monitoring.
Question 2: Data Hierarchy and Applications of DBMS
Data Hierarchy
Data hierarchy means the organized structure of data from the smallest unit to the largest unit.
| Level | Meaning | Example |
|---|---|---|
| Bit | Smallest unit of data, 0 or 1 | 0, 1 |
| Byte / Character | A letter, number, or symbol | A, 5, @ |
| Field | A single data item | Student Name |
| Record | A collection of related fields | One student’s full information |
| File / Table | A collection of related records | Student table |
| Database | A collection of related files or tables | University student database |
Example
In a university database:
Field: Student ID, Name, Department, CGPA
Record: 241-11-123, Rahim, BBA, 3.75
Table: Student Information Table
Database: DIU Student Management Database
Applications of DBMS
| Application Area | Use of DBMS |
|---|---|
| Banking | Managing customer accounts, transactions, loans, and ATM records |
| Education | Managing student records, results, course registration, and attendance |
| Business | Managing sales, inventory, employees, customers, and financial data |
| Healthcare | Managing patient records, appointments, prescriptions, and billing |
| E-commerce | Managing products, orders, payments, and customer profiles |
| Human Resource Management | Managing employee salary, attendance, recruitment, and performance |
Conclusion
A DBMS helps organizations store, organize, retrieve, update, and secure data efficiently. It improves decision-making and reduces data duplication.
Question 3: Operating System and Its Types
Concept of Operating System
An operating system is system software that works as an interface between the user and computer hardware. It manages hardware resources and allows users to run application software.
Main Functions of Operating System
| Function | Explanation |
|---|---|
| Process management | Controls running programs and tasks |
| Memory management | Allocates and manages RAM |
| File management | Stores, organizes, and retrieves files |
| Device management | Controls devices like printer, keyboard, mouse, and monitor |
| Security management | Protects system through passwords and permissions |
| User interface | Provides GUI or command-line interface |
Types of Operating Systems
| Type | Explanation | Example |
|---|---|---|
| 1. Single-user OS | Allows one user to operate the computer at a time. | Windows, macOS |
| 2. Multi-user OS | Allows multiple users to access the system at the same time. | UNIX, Linux Server |
| 3. Multitasking OS | Allows multiple programs to run at the same time. | Windows 11, macOS |
| 4. Real-time OS | Gives immediate response, used in critical systems. | RTLinux, VxWorks |
| 5. Distributed OS | Manages multiple connected computers as one system. | Amoeba, Plan 9 |
| 6. Mobile OS | Designed for smartphones and tablets. | Android, iOS |
| 7. Network OS | Manages network resources, users, and shared files. | Windows Server, Linux Server |
Conclusion
The operating system is essential because it controls the entire computer system and makes hardware usable for business and personal applications.
Question 4: Impact of 5G and Digital Collaboration Platforms
Impact of 5G on Connectivity and Performance
5G is the fifth generation of mobile network technology. It provides faster speed, lower delay, and better connectivity than previous networks.
