Activities, questions, directions, exercises, and discussions are carefully stated for you to understand each lesson. Each SLM is composed of different parts. Each part shall guide you step-by-step as you discover and understand the lesson prepared for you. Pre-tests are provided to measure your prior knowledge on lessons in each SLM. This will tell you if you need to proceed on completing this module or if you need to ask your facilitator or your teacher's assistance for better understanding of the lesson. At the end of each module, you need to answer the posttest to self-check your leaming. Answer keys are provided for each activity and test. We trust that you will be honest in using these. In addition to the material in the main text, Notes to the Teacher are also provided to our facilitators and parents for strategies and reminders on how they can best help you on your home-based learning. Please use this module with care. Do not put unnecessary marks on any part of this SLM. Use a separate sheet of paper in answering the exercises and tests. And read the instructions carefully before performing each task. If you have any questions in using this SLM or any difficulty in answering the tasks in this module, do not hesitate to consult your teacher or facilitator. Thank you NegOr_Q4 C8810 Modulel-4_V2What I Need to Know This module covers the knowledge, skills and attitudes on networking, using tools and LAN cabling. The scope of this module permits it to be used in many different learning situations. The language used recognizes the diverse vocabulary level of students. The lessons are arranged to follow the standard sequence of the course. But the order in which you read them can be changed to correspond with the textbook you are now using, ‘The module is divided into four lessons, namely: + Lesson 1 - Computer Networking + Lesson 2- Common Tools for Networking After going through this module, you are expected t + Identify necessary network materials in accordance with established procedures and check against system requirements. + Check tools, equipment, and testing devices in accordance with established procedures. + Install network cables and cable raceways in accordance with established procedures and installation requirements. + Follow OHS standards and SS principles according to enterprise requirements. + Configuring client device systems, a What I Know Direction.

Do you know causes it? Various researches indicate that in many cases, the network is down on due to poor cabling systems, Installing standard structured cabling systems can eliminate much of this downtime. A network is defined as two or more computers connected to share resources, It refers to any interconnected group or system that shares information. Computers are networked according to certain protocols such as TCP/IP. TCP/IP is one of the rules or standards that allow computers on the network to communicate with one another. 2 NegOr_Q4_C8S10_Modulel-4_V2GF What’s In Direction: Unscramble the letters to form a word. Write your answers on your notebook or answer sheets. 1, ITTENERN — 2. WETKRON — Ww What’s New Direction: Try to identify what type of network is in the picture 3 NegOr_Q4_C8S10_Modulel-4_V2What is It ‘Types of Network Networks are categorized by several methods, including the technology used and the size of the network. The following are network categories based on size or physical area they cover: 1, Personal Area Network (PAN) - composed of personal devices like cell phone and notebook — computer, communicating at close range at least about 20-30 feet (approximately 6-9 meters). PANS can use wired connections (such as USB or FireWire) or wireless connections (such as Bluetooth or infrared). The reach of a PAN is typically close but this is expected to increase with technology improvements. 2. Local Area Network (LAN) -— used for workstations, servers, printers, and other devices to communicate and share resources and covers a small local area such as a home, office, other building, or small group of buildings. LANs can use wired (most likely Ethernet) or wireless (most likely Wi-Fi, also called 802.11) technologies. 3. Wireless LAN (WLAN) - covers a limited geographical area and other places where networking cables are difficult to install, such as outdoors, in public places, and in homes that are not wired for networks, 4. Campus Area Network (CAN) - a computer network made up of an interconnection of local area networks (LANs) within a limited geographical area. It is also a form of a metropolitan area network, specific to an academic setting. ee =e 4 [Neg0r_Q4_CSS10_Modulel-4_V2. Metropolitan Area Network (MAN) - a network that can cover a large campus or city. (A small MAN is sometimes called a CAN or campus area network.) It uses wireless network technology (most likely LTE or 7 WiMAX) and/or wired (for e: with fiber-optic cabling). ample, Ethernet Wide Area Network (WAN) - is made up of many smaller networks and covers a large geographical area. Internet is the best-known WAN. Some technologies used to connect a single computer or LAN to the Internet inchide DSL, cable Internet, satellite, cellular WAN, and fiber optic. Global Area Network (GAN) - no common definition and its specification is in development by several groups. In general, however, is intended for supporting mobile communications across an arbitrary number of wireless LANs, satellite coverage areas, etc. Virtual Private Network (VPN) — a computer network in which some of the links between nodes are carried by open connections or virtual circuits in some larger network (e.g., the Internet} instead of by physical wires. The data link layer protocols of the virtual network are said to be tunneled through the larger network when this is the case. One common application is secure communications through the public Internet, but a VPN need not have explicit security features, such as authentication or content encryption. 5 NegOr_Q4_C8S10_Modulel-4_V2Network Topology Network topology or physical topology is the arrangement of the connections between computers. ‘Types of Network Topology a ff ‘\ * = & a 1. Mesh Network - each node (a computer or other device that ‘uses the network} on the network is responsible for sending and receiving transmissions to any other node to which it wants to communicate without a central point of communication. When each node connects to every node on the network, the network is called a fully connected mesh topology. 2, Ring Network - works by passing a token around the nodes that form a ring, However, this topology is seldom used today because one down computer or a broken cable can stop all connections or communication on the ring. 3. Bus Network Another old topology is a bus network whereby all computers are connected in a sequential line. The bus network worked better than a ring network because one down computer does not prevent other computers from communicating on the bus. However, a broken cable can still bring down an entire bus network. 4, Star Network ~ uses a centralized device (switch or hub) to manage traffic on the network. Star networks are almost totally used for LANs today. An advantage of a star network is that one down computer or one broken cable does not bring down the entire network. When a star network uses multiple switches in sequence, the switches form a bus network, and the network topology is called a star bus network or a hybrid network. 6 NegOr_Q4_C8S10_Modulel-4_V2© What I Have Learned ‘Think back on something that you have learned from this Learner’s Material.

Make sure that you are familiar with the correct use of each tool and that the correct tool is used for the current task. Skilled use of tools and software makes the job less difficult and ensures that tasks are performed properly and safely. Using tools properly helps prevent accidents and damage to equipment and people. 10 NegOr_Q4_CSS10_Modulel-4_V2What’s New Re Direction: Identify what network tool is in the picture.
