Study Notes
Computer Basics
- Desktop computers consist of a monitor, keyboard, CPU, speakers, printer, and mouse.
- The operating system is typically stored on an internal hard drive.
Storage and Performance
- Performance issues may occur due to declining free space on a hard drive.
- Essential files can be backed up using an external hard drive, especially for large data storage requirements (e.g., over 80 GB).
- RAM expansions can enhance performance by providing more temporary storage for applications.
Input and Output Devices
- Input devices include webcams, mice, and touchpads; printers are not classified as input devices.
- Projectors are ideal for delivering presentations in classrooms or conference rooms.
- A voice synthesizer assists users with visual impairments, converting text to speech.
Maintaining and Restoring Systems
- Users should consider restoring their operating system when apps fail to launch or system performance slows.
- Data should be transferred to external storage before restoring the operating system.
- For hardware maintenance, start by turning off the computer and disconnecting from power.
Storage Types and Formats
- Blu-ray discs are an example of optical medium storage.
- External hard drives and optical media serve as transportable storage solutions.
CPU and Processing
- The CPU processes input data through its two essential components: the Control Unit and Arithmetic Logic Unit.
- Processing instructions follow the sequence: Fetch, Decode, Execute, and Store.
- Bottlenecking occurs when CPU performance is high, but bus speed is slow, affecting overall performance.
Software and Drivers
- Device drivers control connected devices and can be updated using OS prompts or from the manufacturer’s website.
- System software encompasses utilities and operating systems; application software is also a key category.
Network and Connectivity
- A network interface card allows a computer to connect to a router.
- Plug-and-play devices require no manual driver installation; they function immediately upon connection.
Cloud and External Storage
- Cloud storage enables access to files across multiple devices and is a secure backup solution.
- Memory cards can be prone to damage; proper storage precautions can mitigate risks of data loss.
Battery and Maintenance
- It is recommended to fully charge battery-operated devices prior to first use.
- Overheating from direct sunlight can adversely affect various computer components, including LCD screens and processors.
Miscellaneous
- Solid state drives offer greater durability compared to traditional hard disk drives.
- Benchmark tests evaluate the performance of hardware components.
- RAID technology stands for Redundant Array of Independent Disks, offering data redundancy and performance improvements.
Data Representation
- Data is stored in computers as binary digits (1s and 0s), which represent all file types, including ASCII conversion for textual data.
- Optical character recognition technology converts scanned documents into editable text formats.
Issues and Solutions
- Slow performance can be remedied by uninstalling unnecessary applications or upgrading RAM.
- Hardware issues, such as a faulty power or video cable, can cause display problems.
