Computer Hardware Quiz: Basics and Fundamentals

Study Notes

CPU and Video Cards

CPU speed refers to how fast it can process instructions, and faster CPUs can handle more tasks in less time.
A video card is a separate hardware component that is added to a computer to handle graphics processing, while on-board video is integrated directly into the motherboard.
PCI Express (PCIe) slots are commonly used for video cards.

Expansion Slots and RAM

PCI (Peripheral Component Interconnect) slots are used for adding expansion cards.
To install computer memory (RAM), align the memory module with the slot on the motherboard and firmly press it down until it clicks into place.

Software and Networking Basics

Open Source software is software whose source code is freely available for anyone to view, modify, and distribute.
Proprietary software is owned by a specific company or individual, and its source code is not freely available.
System software manages the computer's hardware and provides a platform for running application software, while application software performs specific tasks for the user.
A computer network is a group of computers and other devices connected together to share resources and communicate with each other.

Networking Concepts

A data link is a connection between two devices that allows them to exchange data.
A node is any device connected to a network, such as a computer or printer.
LAN (Local Area Network) covers a small geographic area, MAN (Metropolitan Area Network) covers a larger area like a city, and WAN (Wide Area Network) covers the largest area, often spanning across countries or continents.
In a Peer-to-Peer Network, devices communicate directly with each other without the need for a central server.
In a Client-Server Network, client devices request services or resources from a central server, which manages and provides those resources.

Network Setup and Security

Setting up a home network involves connecting devices like computers, printers, and routers together using Ethernet cables or Wi-Fi, and configuring network settings to enable communication and resource sharing.
WEP, WPA, WPA2 are types of encryption protocols used to secure wireless networks.
Firewalls are software or hardware devices that monitor and control incoming and outgoing network traffic to protect against unauthorized access.

Networking Hardware and Cables

Switches are devices that connect multiple devices on a network and manage data traffic between them.
Bridges connect two separate network segments.
Gateways connect different types of networks together, such as connecting a LAN to the internet.
Different types of cables include Ethernet cables for wired connections, HDMI cables for audio and video signals, and USB cables for connecting peripherals like printers and external hard drives.
Fibre Optic cables use light to transmit data and offer high-speed and reliable communication over long distances.

Description

Test your knowledge on basic computer hardware concepts such as CPU speed, video cards, and PCI Express slots. Understand the differences between a video card and on-board video, as well as the importance of CPU speed in a home computer.
