A university called 'LearnMore' is currently receiving student applications for the new year - NSC Information Technology - Question 2 - 2023 - Paper 2

One other component that processes data in a computer system is the GPU (Graphics Processing Unit).

1. Solid State Drive (SSD): A common type of flash storage, offering high speed and reliability.

2. SD Card: A portable flash storage option for easy data transfer.

A cloud-based virtual server is a server that operates on virtualized hardware hosted on the internet. It does not exist as a physical entity, allowing users to access and manage resources flexibly and efficiently without the need for on-premises hardware.

1. Accessibility: Cloud virtual servers can be accessed from any location at any time with an internet connection, enhancing operational flexibility.

2. Scalability: They can be adjusted to meet the changing needs of the organization without the need for physical upgrades.

1. No Installation Required: Users do not need to install software on their own devices, simplifying deployment.

2. Collaboration Features: SaaS applications often include tools for real-time collaboration, enhancing teamwork.

Acquiring a single-user license allows each user to have their own instance of the software, ensuring they receive updates and support, and prevents unauthorized sharing or potential licensing violations.

A backup strategy is a comprehensive plan that outlines how data will be backed up and restored to prevent loss. It helps prevent downtime by ensuring that all critical data is regularly copied and can be quickly restored in the event of data loss or system failure.

1. Internet Access Required: Users must have reliable internet access to retrieve data, which can lead to issues during outages.

2. Bandwidth Limitations: Large backups can require significant bandwidth, which could slow down other operations.

The correct term is power user, as they typically use advanced features of software applications.

1. Self-Replication: A computer worm can duplicate itself across networks without user intervention.

2. Exploitation of Vulnerabilities: Worms often take advantage of security flaws in software to spread to other systems.

Antivirus products are designed to detect and remove malware, including worms, that may infiltrate a system. While firewalls block unauthorized access, they do not inherently stop malware already present on a device from executing.

Solid-state drives (SSDs) do not suffer from the same fragmentation issues as traditional hard drives because they have no moving parts. Data can be accessed instantly regardless of its location on the drive, making defragmentation unnecessary and potentially harmful to the SSD's lifespan.
