Study Notes
Memory Types
- Flash memory is non-volatile, meaning it retains data even when power is off.
- Volatile memory loses its contents when power is disconnected, critical for temporary data storage.
Storage Devices
- Cloud storage requires an Internet connection for data access and storage.
- Internal hard drives, solid-state drives, and flash memory do not need an Internet connection.
Computer Types
- A desktop computer has a system unit that is separated from the monitor, allowing for greater customization and upgrade options.
- All-in-one computers, laptop computers, and tablets have integrated system units.
Coding Systems
- An 8-bit coding scheme allows for the representation of one character per 8 bits, fundamental in computer data processing.
Processor Requirements
- High-powered processors are generally unnecessary for basic tasks like email and web browsing, focusing on efficiency rather than raw power.
Pointing Devices
- Touch pointer is not categorized as a pointing device; trackballs, touchpads, and mice are common examples.
Printing Technology
- Plotters are not portable and are complex devices unable to connect easily with mobile devices, contrasting with conventional printers.
Device Connectivity
- Device drivers are essential programs that enable communication between the computer and attached hardware, ensuring proper functionality.
Data Transmission
- The speed of data transfer on a bus is determined by the word size, influencing overall system performance.
Repair Scenarios
- A broken screen is a primary indicator for seeking professional repair for computers and mobile devices due to potential complexity and safety concerns.
Power Protection
- Uninterruptible power supplies (UPS) and surge suppressors safeguard computers from power outages, providing temporary backup and protection from voltage spikes.
Troubleshooting Techniques
- When dealing with display problems, checking cable connections is a recommended initial troubleshooting step before resorting to professional help or equipment replacement.
