Study Notes
Chapter 7: Networking: Connecting Computing Devices
- Chapter 7 of Technology in Action discusses networking concepts.
- Learning objectives cover describing computer networks, their pros and cons; explaining network definitions; describing transmission media; outlining necessary hardware and software; and summarizing broadband internet access options.
- Additional objectives include understanding wireless internet access, planning home networks, connecting devices to the network, and troubleshooting, and securing and managing wireless networks.
Networking Fundamentals
- A computer network connects two or more computers to communicate.
- Each device within a network is considered a node—includes computers, peripherals (like printers), and network devices (like routers).
- Benefits of networking include sharing high-speed internet, printers, files, and enabling easier communication.
- The disadvantage of networks is the initial setup and administration time.
- Data transfer rate (bandwidth) is the maximum possible speed data can travel.
- Throughput is the actual speed of data transfer.
- Measurements are in megabits per second (Mbps) or gigabits per second (Gbps).
Network Architectures
- Networks can be classified by distance: personal area networks (PANs), local area networks (LANs), home area networks (HANs), metropolitan area networks (MANs), and wide area networks (WANs).
- PANs connect devices close to a single person.
- LANs connect devices within a small area, like a home or office.
- HANs are specific types of LANs located in a home.
- MANs span a large area, such as a city.
- WANs cover large geographical areas globally.
- Networks are also classified by administration levels; client-server networks depend on a central server, whereas peer-to-peer networks allow devices to connect directly.
Classifying Networks by Protocols
- Ethernet is a common networking protocol developed by IEEE.
- It includes wireless (Wi-Fi) and wired (gigabit Ethernet [GbE]) types.
- Backward compatibility allows current devices to use earlier standards.
Network Components
- Networks require a means of connection (cables or wireless), specialized hardware to allow nodes to communicate, and software to run the network.
- Network interface cards (NICs) are integrated network adapters for each node on the network.
- Modems translate signals between digital and analog for broadband connections.
- Routers transfer data between networks.
- Switches act as traffic signals within a network.
Network Components: Software
- P2P (peer-to-peer) networks use operating system software for device communication while client-server networks utilize central servers and specialized network operating system (NOS) software.
Connecting to the Internet
- Broadband is the preferred method for internet access, using technologies like cable internet, DSL (digital subscriber line), and fiber-optic service.
- Cellular and dial-up connections might be alternatives in limited circumstances.
- Obtaining internet access typically requires a connection from an Internet Service Provider (ISP)
Installing and Configuring Home Networks
- Planning a home network involves listing devices, utilizing the latest networking standards, and employing the most current equipment.
- Routers and switches are critical networking devices.
- Specialized devices such as NAS (Network Attached Storage) and home network servers support storage and management, respectively.
Troubleshooting Wireless Networks
- Maximum range, obstacles, and signal placement affect wireless network performance..
- Wireless range extenders can enhance the signal.
Managing and Securing Wireless Networks
- Securing a wireless network involves employing encryption protocols, changing the network name (SSID), disabling SSID broadcast, changing default passwords, creating unique passwords, and using additional security methods such as access controls, limited signal range, updated firmware, and disabling remote access.
