Olatan CSS NC II Trainer 9 INFORMATION SHEET 1.1 What is Network? A network is a collection of computers and related equipment (printers, webcams, game consoles, etc.) connected so that data can move between them. Even if you have a single computer, it looks to the Internet as part of a network. The Internet, then, is a network of networks. Three Basic Network Categories Local Area Network- the smallest of the three network types, consist of PCs connected together within a limited area, such as within the same building, floor or department. Metropolitan Area Network – are network that spans no more than 50 miles. It is design to connect LANs spanning a town or city Wide Area Network – used to distribute information thousands of miles among thousands of users. Network Hardware Network Interface Card (NIC) – also called LAN card, a printed circuit board, an adapter that plugs into the computer’s motherboard when connected with a network cable, provides the physical link between your computer and the network. Router – a device that forwards data packets between Local or Wide Area Network groups. Network Switch – It helps determine how data moves over large networks. Repeater – a device that strengthen signals and allow s it to stay clear over longer distances. Prepared by: Page Core # 2 : Set-up Computer Networks Mr. Arvincent G.

Olatan CSS NC II Trainer 11 INFORMATION SHEET 1.2 Network Cable Cable is the medium through which information usually moves from one network device to another. There are several types of cable which are commonly used with LANs. In some cases, a network will utilize only one type of cable, other networks will use a variety of cable types. The type of cable chosen for a network is related to the network's topology, protocol, and size. Examples of network media: 1. Unshielded Twisted Pair (UTP) Cable 2. Shielded Twisted Pair (STP) Cable 3. Coaxial Cable 4. Fiber Optic Cable 5. Wireless LANs 1. Unshielded Twisted Pair (UTP) cable The least expensive and most popular network media. The standard connector for unshielded twisted pair cabling is an RJ-45 connector. This is a plastic connector that looks like a large telephone-style 2. Shielded Twisted Pair (STP) Cable Although UTP cable is the least expensive cable, it may be susceptible to radio and electrical frequency interference (it should not be too close to electric motors, fluorescent lights, etc.). If you must place cable in environments with lots of potential interference, or if you must place cable in extremely sensitive environments that may be susceptible to the electrical current in the UTP, shielded twisted pair may be the solution. Shielded cables can also help to extend the maximum distance of the cables. 3. Coaxial Cable Coaxial cabling has a single copper conductor at its center. A plastic layer provides insulation between the center conductor and a braided metal shield. The metal shield helps to block any outside interference from fluorescent lights, motors, and other computers. This cable is commonly used by television industries. Prepared by: Page Core # 2 : Set-up Computer Networks Mr. Arvincent G. Olatan CSS NC II Trainer 12 4. Fiber Optic Cable Fiber optic cabling consists of a center glass core surrounded by several layers of protective materials. It transmits light rather than electronic signals eliminating the problem of electrical interference. This makes it ideal for certain environments that contain a large amount of electrical interference. 5. Wireless LANs More and more networks are operating without cables, in the wireless mode. Wireless LANs use high frequency radio signals, infrared light beams, or lasers to communicate between the workstations, servers, or hubs. Each workstation and file server on a wireless network has some sort of transceiver/antenna to send and receive the data. Wireless networks are great for allowing laptop computers, portable devices, or remote computers to connect to the LAN. CABLE INSTALLATION GUIDES The two most common network cable: 1. Straight through cable – Connected from PC to switch/hub 2. Crossover cable – Connected from Pc to PC (limited to two computers only) What is RJ45? RJ stands for Registered Jacks. These are used in telephone and data jack wiring registered with FCC. RJ-11 is a 6-position, 4-conductor jack used in telephone wiring, and RJ-45 is a 8-position, 8-conductor jack used in 10BaseT and 100BaseT Ethernet wiring. Wiring Standards for RJ45 1. T568A 2.

Olatan CSS NC II Trainer 26 INFORMATION SHEET 4.1 Testing Your Computer Network You’ve set up all your network switches, plugged in all the cables, and configured all your computers. One task remains before you can declare yo ur network finished: You must verify that the network works as expected. Here are a few simple tests you can conduct to make sure your network is functional. Check the physical connections. Check that the Link light — the little red or green light next to the RJ-45 port — is lit on every computer. You must check this light both on the computer itself and on the switch or router the computer is plugged into. If this light is not on, you have a connection problem — most likely a bad cable. Verify that you can log on. When you’re sure the physical connections are good, you should attempt to log on to each of your network computers using a valid domain user account. Check the network configuration. Click the Start button, type cmd and press Enter. Then, enter the command and press Enter. IP Address (Version 4) 192.168.8.101 Default Gateway 192.168.8.1 Prepared by: Page Core # 2 : Set-up Computer Networks Mr. Arvincent G. Olatan CSS NC II Trainer 27 This command will spit out numerous lines of information. The line you’re looking for should resemble this: Prepared by: Page Core # 2 : Set-up Computer Networks Mr. Arvincent G. Olatan CSS NC II Trainer 28 IPv4 Address........................ 192.168.1.125(Preferred) Verify that the computers can ping each other. Another basic test you should perform is to use the ping command from a command prompt to make sure that the computers on your network can contact one another. Ping another computer (LAN only) Click the Start button, type cmd and press Enter. Then, enter the command PING 192.168.8.100 and press Enter. Ping a website (WAN-Internet) Click the Start button, type cmd and press Enter. Then, enter the command PING 192.168.8.100 and press Enter. Prepared by: Page Core # 2 : Set-up Computer Networks Mr. Arvincent G. Olatan CSS NC II Trainer 29 INFORMATION SHEET 4.2 What is an IP Address? An Internet Protocol address (IP address) in layman’s terms is basically the address given to your computer when it’s connected to a network. Technically speaking, an IP address is a 32-bit number that signifies the address of both the sender and receiver of packets on a network. Class Address Range Supports Class A 1.0.0.1 to 126.255.255.254 Large networks with many devices Class B 128.1.0.1 to 191.255.255.254 Medium-sized networks. Class C 192.0.1.1 to 223.255.254.254 Small networks (fewer than 256 devices) Class D 224.0.0.0 to 239.255.255.255 Reserved for multicast groups. Reserved for future use, or Research and Class E 240.0.0.0 to 254.255.255.254 Development Purposes. The two main types of IP Address 1. Static IP Address As the name speaks, the static IP addresses are those types of IP address that never change once they are assigned to a device on a network. No doubt this type of addressing is cost effective but could have a high security risk. Static IP addresses are mostly used by web, email and gaming servers who don’t care much about hiding their locations. 2. Dynamic IP Address On the other hand, a Dynamic IP address changes each time the device logs in to a network. This kind of IP address is very tough to trace and are thus used by companies and business firms. You must be thinking as to who or what allocates this Dynamic IP a ddress every time the device logs in. Well, these IP address are assigned using DHCP (Dynamic Host Configuration Protocol). Talking about DHCP in detail is bey ond the scope of this article and we will take it up in a future post. Prepared by: Page Core # 2 : Set-up Computer Networks Mr. Arvincent G. Olatan CSS NC II Trainer 30 How to set a Static IP Address Normally, your computer’s IP Address has a dynamic IP Address. To find out your computer’s Dynamic IP simply click the Start button, type cmd and pres s Enter. Then, enter the command IPCONFIG and press Enter. To permanently set it as your Static IP 1. Right click on Wifi icon (Laptop) or LAN icon (PC) at the notification bar and select Open Network and Sharing Center 2. Select Change adapter settings 3. Right click Local Area Connection and select Properties Prepared by: Page Core # 2 : Set-up Computer Networks Mr. Arvincent G. Olatan CSS NC II Trainer 31 4. Select Internet Protocol Version 4 and click on Properties Prepared by: Page Core # 2 : Set-up Computer Networks Mr. Arvincent G. Olatan CSS NC II Trainer 32 5. Select Use the following IP address and enter the IP addresses from the command prompt (IPCONFIG). Note: If you change the default gateway and preferred DNS server, you will lose your internet connection. Prepared by: Page Core # 2 : Set-up Computer Networks Mr. Arvincent G.
