Study Notes
Computer Performance and Maintenance
- Bottlenecking occurs when the CPU operates efficiently, but the slower bus speed hinders overall performance.
- Increasing RAM boosts temporary data storage, enhancing the performance of laptops under heavy application use.
- Key components of a CPU - Control Unit and Arithmetic Logic Unit - are crucial for processing input into output.
Data Storage and Transfer
- The internal hard drive is where the operating system is typically stored on computers.
- Bus width greatly affects the speed at which data can travel within the system.
- Data can be stored using various devices, including external hard drives and optical media, facilitating data transfer between computers.
Memory and Processing
- Data is finally stored in binary digits format, the fundamental language of computers.
- Dynamic RAM (DRAM) needs constant refreshing to maintain its stored contents and is the prevalent RAM type in PCs.
- A CPU follows the sequence of operations: fetch, decode, execute, store during a machine cycle.
Device Management and Software
- Periodic anti-virus scans and software updates are essential for safeguarding computers from malware.
- Updating device drivers can be done by executing updates within the operating system or downloading the latest software from the manufacturer's site.
Environmental and Hardware Considerations
- Using a UPS (Uninterruptible Power Supply) or surge protector is a critical step in maintaining hardware integrity.
- Computers are sensitive to extreme temperatures and humidity; they cannot generally operate efficiently under harsh environmental conditions.
E-Commerce and Online Environments
- B2B e-commerce involves transactions requiring team reviews before final purchases, emphasizing rigorous evaluation.
- Online retailers process orders quickly through the aid of computer-manufacturing systems.
Web Development and Digital Literacy
- Data for web applications is typically stored in cloud storage, enabling easy access from multiple locations.
- Information literacy is vital for identifying the right tools to find relevant information efficiently.
Multimedia and Communication
- Devices like gamepads serve as controllers to manage on-screen movements during gaming.
- Augmented reality apps utilize location data to enhance user experiences, such as locating nearby restaurants or shops.
Copyright and Digital Rights
- Platforms like Project Gutenberg are suitable for authors who want to retain copyright while allowing free distribution of their works.
Miscellaneous Knowledge
- Unicode coding accommodates a vast array of characters, including those from multiple languages, broadening accessibility.
- Understanding the functionality of devices such as webcams, touchpads, and mice is integral, as they are crucial input devices.
