What you'll learn
Basic of Hardware and Networking (BHN) is a foundational area of study that covers the physical components of a computer and how those computers are connected to communicate and share resources. The hardware and software components work together to form a functional computer system and network.
Basic computer hardware
Hardware refers to the physical, tangible parts of a computer system. BHN describes components such as:
- Central Processing Unit (CPU): The "brain" of the computer that performs calculations and carries out instructions.
- Motherboard: The main circuit board that connects all hardware components, allowing them to communicate.
- Random Access Memory (RAM): Temporary, or "volatile," memory that stores data the CPU is actively using for quick access.
- Storage Devices: Components like Hard Disk Drives (HDD) or Solid-State Drives (SSD) that store data permanently.
- Power Supply Unit (PSU): Supplies power to the internal components of the computer.
- Input/Output Devices: Peripherals that allow a user to interact with the computer, such as a keyboard, mouse, and monitor.
Basic networking concepts
Networking is the process of connecting multiple computers and devices to share data and resources. The basic concepts include:
- Network Components: Devices like servers, clients, and network peripherals that are connected together.
- Connecting Devices: Hardware such as routers, switches, and hubs that link different computers or networks.
- Transmission Media: The communication channels used to transfer data, which can be wired (like Ethernet cables) or wireless (like Wi-Fi).
- Network Topologies: The layout or structure of the network, which can include common patterns like star, bus, or ring.
- IP Addressing: A logical address assigned to each device on a network that allows for communication.
- Protocols: The rules and standards that govern how data is exchanged between devices on a network.
Skills and applications
Studying BHN can provide hands-on skills valuable for IT careers, such as:
- Assembling and disassembling a personal computer.
- Installing and troubleshooting an operating system.
- Configuring networks and managing IP addresses.
- Performing basic network security tasks.
- Troubleshooting common hardware and network issues
