What is a LAN?
Answer: A LAN, or Local Area Network is a network that spans a relatively small area, such as a home, office building, or school campus. It connects devices within a limited geographical area.
What are the advantages of using a LAN?
LANs offer several advantages, including fast communication between devices, centralized management of resources, cost-effectiveness, and easy sharing of files and devices.
How are devices connected in a LAN?
Devices in a LAN are typically connected using Ethernet cables or wireless connections (Wi-Fi). They can also be connected through networking hardware like switches and routers.
What is an IP address?
An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to a network. It identifies the device’s location and allows it to communicate with other devices on the network.
How do devices communicate on a LAN?
Devices on a LAN communicate by sending data packets to each other using their IP addresses. This communication is facilitated by networking protocols such as TCP/IP.
What is a subnet mask?
A subnet mask is a numerical value used to divide an IP address into network and host portions. It helps devices determine which part of an IP address corresponds to the local network and which part identifies individual devices.
Traffic Enforcer of Ip address, you’re only allowed to go to a certain area
What is DHCP?
DHCP, or Dynamic Host Configuration Protocol, is a networking protocol that automatically assigns IP addresses to devices on a network. It simplifies network administration by eliminating the need for manual IP address configuration.
What is a router in a LAN?
A router is a networking device that connects multiple LANs or LAN segments together. It forwards data packets between networks, allowing devices in different LANs to communicate with each other.
How can you secure a LAN from unauthorized access?
You can secure a LAN by implementing measures such as setting up strong passwords for network devices, enabling encryption on Wi-Fi networks, configuring firewalls, and restricting access to sensitive resources through user authentication.
Also you can change the IP Address itself to secure LAN
What is a PCIe slot?
A PCIe (Peripheral Component Interconnect Express) slot is a high-speed expansion slot on the motherboard used to connect peripherals, such as graphics cards, network cards, and storage controllers.
What tools are typically needed for computer disassembly? **
Common tools for computer disassembly include screwdrivers (Phillips and flathead), pliers, tweezers, anti-static wrist straps, and possibly a spudger or pry tool for separating components.
Why might someone need to disassemble a computer?
There are several reasons for disassembling a computer, such as performing hardware upgrades (e.g., adding more RAM or replacing a hard drive), cleaning the internal components to prevent overheating, troubleshooting hardware issues, or recycling old components.
What are some safety precautions to take before beginning a computer disassembly?
Before disassembling a computer, it’s essential to power it off completely and unplug it from the electrical outlet. Additionally, wearing an anti-static wrist strap can help prevent damage from electrostatic discharge (ESD). Working in a well-lit area with plenty of space and keeping track of screws and other small components are also important safety measures
How should one approach disassembling a laptop compared to a desktop computer? **
Disassembling a laptop typically requires more careful handling and attention to detail due to the compact design and integrated components. It often involves removing screws from the bottom of the laptop, carefully prying apart the casing, and disconnecting ribbon cables and other connectors. Desktop computers generally have more accessible components and larger, easier-to-handle parts, but still require caution when handling delicate components like the CPU and RAM.
What are some common components that one might encounter when disassembling a computer?
Common components found inside a computer include the motherboard, CPU, RAM modules, hard drives or SSDs, power supply unit (PSU), cooling fans or heat sinks, expansion cards (such as graphics cards or network adapters), and various cables and connectors. When disassembling a computer, each of these components may need to be removed and handled carefully, depending on the purpose of the disassembly.
