Study Notes

Network+ Guide to Networks Eighth Edition - Chapter 1

The book is the Network+ Guide to Networks Eighth Edition, Chapter 1, Introduction to Networking
Objectives for the chapter include distinguishing client-server and peer-to-peer models, identifying network applications and protocols, describing network hardware and common physical topologies, explaining the OSI model's seven layers, and outlining network troubleshooting procedures.
Topology is how parts of a whole work together
Physical topology refers to hardware and describes how computers, devices, and cables are connected to form the physical network
Logical topology describes how access to the network is controlled via software
A Network Operating System (NOS) controls access to the entire network, required by client-server models.
Peer-to-peer (P2P) networks have no centralized control, and the OS of each computer manages its resources
Computers in a P2P network (nodes or hosts) form a logical group
P2P networks may share or prevent access to resources, and each computer user has a local Windows account.
P2P networks only work on one computer at a time
Advantages of P2P networks are simple configuration and lower costs compared to other models.
Disadvantages are limited scalability and security issues.
Client-server networks rely on a centralized directory database managed by the NOS.
A Windows domain is a logical group of computers controlled by a Windows Server.
Active Directory (AD) is a centralized database holding user account information and network security for a domain.
Users can access resources on the network from any computer within the AD domain using AD DS.
Clients request data or services from servers, not directly from each other.
Client access is controlled by the domain database via servers.
Server examples include Windows Server 2016, Ubuntu Server, and Red Hat Enterprise Linux.
Servers require more memory, processing, and storage capacity, plus special hardware like network management functionalities.
Client-server models have advantages over P2P models, including centralized user credentials, centrally controlled shared resources, monitoring, diagnostics, correction, and scalability.
Network services provide the resources and applications available on a network
Includes the applications and the data these applications provide
Client-server applications include a client computer requesting data or services from a server computer
Two primary network protocols are Transmission Control Protocol (TCP) and Internet Protocol (IP)
TCP/IP protocol suite is used by OSs to communicate on a network
The OSI model is a seven-layer reference model for networking communications.
Layers are numbered in order, starting with the Physical layer.
Layers include the Physical, Data Link, Network, Transport, Session, Presentation, and Application layers.
Application layer acts as an interface between applications on separate computers.
Applications use Application layer protocols like browsers or web servers
Utility programs or applications provide services to systems, such as SNMP.
Payload is the data transmitted between applications and operating systems.
Presentation layer formats, compresses, and/or encrypts data for receiving applications
Session layer synchronizes data between applications.
Transport layer is responsible for transporting application payloads between applications.
TCP protocols make a connection to the end host before transmission and check receipt.
UDP does not require a connection and doesn't check the receipt.
Protocols add header information to the data
Encapsulation is the process of adding header information to data
Transport layer uses port numbers for receiving applications.
Large messages are divided into smaller segments by TCP.
UDP messages are called datagrams.
Network layer is responsible for moving messages from one node to another until they reach the destination host, using IP addresses
Network layer includes protocols to find the best route for packets and processes packet fragmentation
The Data Link layer interfaces with the physical hardware of the local network.
Data Link Layer protocols vary with hardware (e.g., Ethernet, Wi-Fi).
Data Link layer includes MAC addresses (hardware addresses) for devices
Physical layer sends bits via wired or wireless transmission.
Transmission can be via wavelengths, voltage signals, or light.
Protocol data unit (PDU) is a technical term for a group of bits.
Network and computer technicians need to protect themselves and equipment
OSHA safety guidelines apply to power tools, lifting heavy objects, and static electricity protection.
Emergency procedures include knowing escape routes, having fire suppression systems, portable fire extinguishers, emergency power-off switches, and suppression agents.
A Material Safety Data Sheet (MSDS) provides safe handling procedures.
Grounding and using ESD straps is necessary to prevent static electricity damage to components.
Proper troubleshooting steps for network problems involve identifying the problem, gathering information, identifying symptoms, questioning users, determining if changes occurred, establishing probable cause, testing the theory, determining next steps and documenting findings.
