CHAPTER 10

This chapter discussed about Planning and Cabling Network. I’ve learned that in order to have a well planned functioning network, one must consider the different factors in choosing a device. These includes: the cost, ports/interfaces, speed, its expandability, its manageability, and its additional features and services. And because there are several types of media, such as UTP, Fiber Optics, and Wireless, there are also some factors to consider in choosing a media, these includes: its cabling length, its cost, adequate bandwidth, ease of installation, and is susceptible to EMI/RFI. I’ve learned that when connecting different types of devices, we shall use straight-through cable, and crossover cable when connecting same types of devices.

                It is also discussed here in this chapter the different end devices that requires IP addresses such as computers (for users and administrator), servers, IP cameras, printers, and IP phones; also network devices that requires IP address: router LAN interfaces and router WAN (serial) interfaces; and lastly are the network devices that requires IP address for management: switches and wireless access points.

                Designing an addressing scheme of the internetwork and assign ranges of network devices, router interface, and hosts are also learned here in this chapter. And in interconnecting devices, I’ve also learned the corresponding interfaces or ports of every Cisco devices, switches, and routers. For the LAN interface is the Ethernet, WAN interface is the serial, console interface for initial configuration of Cisco router or switch, and the Auxiliary interface is for remote management of the router.

                And in making LAN connections,  several cables are used such as UTP straight-through cables, UTP crossover cables, and others. When connecting different types of devices, use straight-through cable. And when connecting the same type of device, use a cross over cable.

                And in making WAN connections, there are also several connectors such as DSL (Digital Subscriber Line), physical serial cables, etc.

                Counting subnet is also reviewed in this chapter, but in this chapter, it is discussed that determining the total number of host is useful to develop its addressing scheme. And the ways for calculating addresses in the network is fully instructed in this chapter.

KEY TERMS:

1.       DCE       

-          Data Communication Equipment.

-          It provides a physical connection to the network, forwards traffic, and provides a clocking signal used to synchronize data transmission between DCE and DTE devices.

-          Some of its examples are modems and interface cards.

2.       DTE

-          Data Terminal Equipment.

-          It is the interface between the router and the DCE. It also controls data coming inbound or outbound.

3.       EMI       

-           interference in a radio receiver or other electrical circuit by electromagnet radiation

        emitted from an external source.

4.       MDI      

-          Medium Independent Interface.

-          It is the pinout order on an NIC card of a PC. It is also known as an uplink port for hubs or switches.

5.       MDIX

-          Media Independent Interface Crossover.

-          It is the pinout of switch or hub in which the input pins on side correspond with the output pins on the other side.
