Study Notes

ICT System Components

Two components of an ICT system:
Hardware (e.g. computers, mobile devices)
Software (e.g. operating systems, applications)

Gig Economy

Example of how PlayTech can make use of the Gig economy:
- Outsource specific tasks to freelancers or independent contractors
Reason why an expert programmer might not be interested in the Gig economy:
- Lack of job security and stability

Merge Cube

The Merge Cube is an educational toy that allows users to hold digital 3D objects
Interacts wirelessly with a mobile device using a wireless network (e.g. Wi-Fi, Bluetooth)

Database Management

The Job card database has two tables: tblEmployee and tblTasks
Fields in the tblEmployee table:
- ID (primary key)
- StaffID (unique staff number)
- Name (employee name and surname)
- Position (employee’s job description)
- ContactNumber (employee phone number)
- HourlyRate (amount paid per hour worked)
Fields in the tblTasks table:
- TaskID (primary key)
- Description (task description)
- Status (task status: In Progress, Pending, or Completed)
- Overdue (whether the task is overdue)
- Daysleft (number of days left before the task should be completed)

Data Security

Suitable data type for the HourlyRate field:
- Numeric or decimal
One way to restrict physical access to data:
- Use biometric authentication (e.g. fingerprint scanning)
Cloud storage is a more secure way to store sensitive data than on a local server because:
- Data is stored in multiple locations, making it harder to access
One other factor that could be used to authenticate users in addition to a password:
- Fingerprint scanning
UPS stands for:
- Uninterruptible Power Supply

Communication Methods

Most appropriate communication method for sending a message to all factory staff with an attachment:
- Email
Two functions of email that justify this recommendation:
- Ability to send attachments
- Ability to send messages to multiple recipients at once
