Study Notes
Introduction to Networks
- Networks are collections of connected devices like computers, printers, and gaming consoles.
- The Internet is a network of networks.
- Three basic network categories:
- Local Area Network (LAN): Smallest type, connecting devices in a limited area: building, floor, department.
- Metropolitan Area Network (MAN): Covers a larger area up to 50 miles, connecting several LANs within a town or city.
- Wide Area Network (WAN): Spanning thousands of miles, allowing communication between users globally.
Network Hardware
- Network Interface Card (NIC): A printed circuit board, plugging into the computer's motherboard, connecting the computer to the network via cable.
- Router: Directs data packets between different network groups (LANs or WANs).
- Network Switch: Determines the data flow over large networks.
- Repeater: Strengthens signals for longer distances.
Computer Networks
- A network is a collection of computers and related equipment connected to allow data to move between them
- Network Interface Cards (NICs) provide the physical link between your computer and the network
- Network Hubs are the central connection point for all devices on a network
- Network Switches are like hubs, but they are more intelligent, allowing data to be transmitted to specific devices on the network
- A Local Area Network (LAN) connects computers within a limited area, such as a building or department
- A Wide Area Network (WAN) connects computers over a large geographic area, such as a country or continent
Network Cables
- Network cables are the physical medium that data travels through
- Unshielded Twisted Pair (UTP) cable is the most common and least expensive, using an RJ-45 connector
- Shielded Twisted Pair (STP) cable is more expensive and includes a protective shield to minimize interference
- Coaxial cable uses a single copper conductor at its center, insulated by a plastic layer and surrounded by a braided metal shield. It is commonly used in television industries
- Fiber Optic cable uses a glass core to transmit light signals, making it resistant to interference. Ideal for environments with high electrical interference
- Wireless LANs use radio signals, infrared light, or lasers for communication between devices, allowing for flexibility and mobility
RJ45
- RJ45 is a standard connector used for Ethernet wiring
- RJ45 has 8 positions and 8 conductor, compared to RJ-11 which is used in telephone wiring
Network Cable Wiring Standards
- There are two main wiring standards: T568A and T568B
- Straight Through cables connect PCs to switches/hubs
- Crossover cables connect two computers directly (limited to two computers)
Network Configuration
- Network configuration refers to setting the controls, flow, and operation of a network
- A patch panel is a device with multiple jacks for connecting and routing circuits, providing flexibility and organization
- A patch panel cable management system ensures organized and neat cable arrangements, adhering to industry standards
Router Configuration
- A router forwards data packets between computer networks, directing traffic on the Internet
- Router configuration allows setting up the network name (SSID), password, and security options
- Changing the WIFI name and password helps protect the wireless network
- Security modes, like WPA-PSK, provide encryption for the wireless connection
Testing Computer Networks
- Once a network is set up, it is essential to test its functionality
- Verify physical connections by checking the Link light on each computer and its connection to the switch/router
- Attempt to log on to each network computer with a valid user account to confirm connectivity
- Use network commands to verify the IP address and default gateway settings on each computer
IP Address
- An IP address is like a home address for a computer on a network.
- An IP address is a 32-bit number
- IP addresses are used for sending and receiving information over a network.
- IP addresses are divided into different classes based on their address range.
- Class A networks are typically large networks, while Class C networks are typically used for smaller networks.
- IP address classes are defined by their address range, which indicates the number of devices that can be connected to the network.
- Class D is reserved for multicast groups.
- Class E is reserved for experimental purposes.
Types of IP Addresses
- Static IP addresses are assigned to a device and do not change.
- Dynamic IP addresses change every time a device connects to a network.
- The Dynamic Host Configuration Protocol (DHCP) is used to assign dynamic IP addresses.
How to set a Static IP Address
- To find the computer's IP address, open the command prompt and type
ipconfig. - Find the IP address assigned to the network connection.
- To set a static IP address, navigate the Network and Sharing Center, right-click on Local Area Connection, and select properties.
- Select Internet Protocol Version 4 and click on Properties.
- Select 'Use the following IP address' and enter the IP address found in the command prompt.
Network Connectivity Tests
- Physical Connections: Check cables and connections.
- Login: Verify the user can log into the network.
- Network Configuration: Verify the settings are correct.
-
Ping Test: Use the
pingcommand to test communication between computers on the network.
Set-up Computer Networks
- This module covers setting up computer networks, a key skill for Computer Systems Servicing NCII.
- The module consists of 4 learning outcomes with learning activities based on information sheets.
- Upon completion, students will be assessed on their knowledge and skills.
Learning Outcome 2: Set network configuration
-
This outcome involves configuring network settings to ensure proper communication between devices.
-
Key tasks include:
- Checking each terminal's connectivity according to the network design
- Diagnosing and resolving any network issues
- Configuring network interface card settings based on the network design
- Verifying communication between terminals based on OS network configuration guides
- Addressing unplanned events according to established procedures
-
The required resources include:
- Computer peripherals
- Desktop computers
- Multi-tester
- Diagnostic software
- RJ45 modular box
- UTP cable
- Assorted pliers
- Assorted screwdrivers
- Anti-static wrist strap
- Crimping tool
- Punch down tool
- USB flash drive
- Computer storage media
Learning Outcome 3: Configure Network Devices
- Learning Outcome 3 outlines the process of configuring network devices, including routers and wireless access points.
- The goal is to establish secure and reliable connections within the network.
- The text discusses the use of a web-based interface for configuring a router's settings:
- Access the router's admin page by entering its default IP address into a web browser.
- Log in using the default username and password.
- Modify settings such as the wireless network name (SSID), security mode, and password.
- Save the configuration changes to apply the new settings.
Learning Outcome 4: Inspect and test the configured computer networks
- This outcome emphasizes the importance of thorough inspection and testing to ensure the network operates correctly.
- After configuring the network, it is crucial to:
- Perform a final inspection to verify that the configuration aligns with manufacturer instructions.
- Conduct tests to ensure the network is operating safely.
- Prepare reports according to company requirements to document the network configuration and testing results.
