Study Notes
Categories of Computer Peripherals
- Computer peripherals are classified into three categories based on data flow: input devices, output devices, and input/output/storage devices.
- Input devices exclusively send data to the computer, while output devices receive data without sending information back.
- Some devices can perform both functions, allowing bidirectional data communication.
Input Devices
- Input devices are one-way peripherals that send information to computers without receiving any feedback.
- Common examples include:
- Mouse: Directs cursor movement by sending positional data.
- Microphone: Captures audio input and transmits it to the computer.
Output Devices
- Output devices receive data from the computer but do not send data back.
- Examples include:
- Speakers: Produce sound output based on data received from the computer.
- Monitors: Display graphical data; standard monitors serve as output only, unlike touchscreen monitors, which can interact with input.
Computer Memory
- Memory is crucial for system performance; without it, computers cannot execute tasks.
- Two main types of memory:
- Primary Memory: Includes RAM (volatile) and ROM (non-volatile).
- Secondary Memory: Includes hard drives and CDs for permanent data storage.
Secondary Storage Devices
- These devices complement primary storage by providing permanent data storage.
- Use non-volatile memory, allowing the retention of data even when powered off.
- Storage ranges from megabytes to petabytes, holding programs, operating systems, and user data.
- Common uses include data backup, long-term archiving, and storing less critical data.
Use Cases of Secondary Storage
- External storage devices have become popular, notably USB flash drives and cloud-based solutions.
- Cloud services (e.g., Dropbox, Google Drive) provide remote data storage, favored by companies using SaaS models.
Forms of Backup Storage
- Backup storage includes various types of devices:
- Solid-State Drives (SSDs), Hard Disk Drives (HDDs), Cloud Storage
- Optical Drives (CD-ROM, DVD, Blu-ray)
- Removable Media (USB flash drives, SD cards)
- Legacy devices like tape drives and floppy diskettes have been largely replaced.
BIOS Access Methods
- BIOS (Basic Input/Output System) is essential for system boot and hardware configuration.
- Accessing BIOS can typically be done through:
- Hotkeys during boot-up (e.g., F2, DEL).
- Windows' advanced start menu for recovery settings.
- The timing for accessing BIOS is crucial; it should be done just after powering the computer on.
Bluetooth Device Pairing
- To connect a Bluetooth device:
- Ensure the device is powered on and discoverable.
- Navigate to PC settings and add the Bluetooth device.
- Follow prompts to establish a connection.
RAID (Redundant Array of Independent Disks)
- RAID enhances performance and fault tolerance by utilizing multiple drives.
- Key RAID configurations include:
- RAID 0: Performance-focused, no fault tolerance.
- RAID 1: Mirroring for reliability, requires double the storage.
- RAID 5: Combines data striping with parity for fault tolerance.
- RAID 6: Similar to RAID 5 but with greater reliability.
GPU (Graphics Processing Unit) Basics
- GPUs enable high-performance graphics rendering in computers.
- Types of GPUs:
- Integrated GPUs: Embedded within the CPU, sharing system memory.
- Discrete GPUs: Separate cards with dedicated memory, enhancing graphic performance.
- GPUs are essential for gaming, content creation, and computational tasks, freeing up the CPU for other processes.
