Study Notes
Secondary Storage Device
- A device used to store data when the power is off.
- Examples include hard disk drives, magnetic tape, USB memory sticks, memory cards, solid-state drives (SSDs), CDs, DVDs, and Blu-ray discs.
Hardware Components
- Central Processing Unit (CPU): Executes instructions and performs calculations. Multiple cores mean more than one instruction can be processed at once.
- Motherboard: Connects all computer components together.
- RAM (Random Access Memory): Temporary memory for files and applications. Volatile (deleted when power off).
- ROM (Read-Only Memory): Stores the computer's startup instructions. Non-volatile (data retained when power off).
- Power Supply: Provides electricity to all computer components.
- Fan: Keeps the computer cool.
Network Hardware
- A network consists of two or more computers or devices connected via ethernet cables or WiFi.
- Switch: Connects multiple computers, workstations, or printers to the network.
- Server: Manages and stores files or provides services, controlling the network.
- Modem: Converts digital data to analog to transmit over telephone lines and vice versa.
- Router: Directs data packets around a network and can connect different networks together, often used with a modem for internet access.
- Wireless Access Point (WAP): Allows Wi-Fi devices to connect to a network.
Network Topologies
- Star: All devices are connected to a central switch, facilitating easy addition of devices without affecting other components. However, a failure in the central switch affects the whole network.
- Mesh: All devices are interconnected. Offers multiple data paths. More complex to maintain than star, but provides redundancy and flexibility.
Types of Networks
- LAN (Local Area Network): A network covering a small geographical area like a school or office.
- WAN (Wide Area Network): Covers a large geographical area, like the internet.
- PAN (Personal Area Network): Connects devices within a small area, often less than 10 meters.
