(2bi)
In crash recovery, a checkpoint is a saved state of a system at a specific point in time. It helps ensure data consistency by recording critical information about ongoing processes and transactions. After a crash, the system can use the checkpoint to restore operations, minimizing data loss and reducing recovery time.

(2bii)
(PICK TWO ONLY)
(i) Both are essential components of decision-making processes.
(ii) Both can be stored and retrieved using computers.
(iii) Both can be represented in various formats, such as text, numbers, or graphics.
(iv) Both are used in communication and analysis.
(v) Both are valuable assets in organizational operations.

(i) Select the paragraph by clicking and dragging the cursor over it.
(ii) Right-click the selected paragraph and choose “Cut” or press “Ctrl+X”.
(iii) Place the cursor at the desired location for the paragraph.
(iv) Right-click the new location and select “Paste” or press “Ctrl+V”.
(v) The paragraph will be moved to the new location.

(3aii)
(PICK FOUR ONLY)
(i) Microsoft Excel
(ii) Google Sheets
(iii) LibreOffice Calc
(iv) Apple Numbers
(v) WPS Office Spreadsheet
(vi) Zoho Sheet
(vii) Apache OpenOffice Calc

(3bi)
A distributed database is a collection of data that is stored across multiple physical locations, which can be on different computers or servers, yet managed and accessed as a single unified database system.

(3bii)
(PICK THREE ONLY)
(i) Analyzing and identifying user requirements.
(ii) Designing system solutions to meet those requirements.
(iii) Conducting feasibility studies for system implementation.
(iv) Collaborating with stakeholders to gather and clarify system needs.
(v) Preparing system specifications and documentation.
(vi) Overseeing the testing and implementation of new systems.

(4ai)
(PICK TWO ONLY)
(i) A database is a collection of organized data, while a database management system (DBMS) is software used to manage and interact with the database.
(ii) A database stores the actual data, while a DBMS provides tools to manage, retrieve, and update that data.
(iii) A database is passive and stores information, while a DBMS is active and enables users to perform operations like queries and updates.
(iv) A database can exist independently, while a DBMS is required to access, manipulate, and organize the database.
(v) A database focuses on data storage and retrieval, while a DBMS focuses on providing security, concurrency control, and backup features for the database.

Mesh network topology is a network design where every device (node) is connected directly to one or more other nodes. This structure provides multiple paths for data to travel, ensuring reliability and redundancy. If one connection fails, data can still reach its destination through alternative routes.

(5bi)
Local Area Network is a network that connects computers and other devices within a limited area, such as a home, office, or school. LANs enable devices to share resources like files, printers, and internet connections, using wired (e.g., Ethernet) or wireless (e.g., Wi-Fi) communication.
