Chapter Summaries In chapter one it is a general overview of the components and hardware that are necessary for a computer to function. The four major components for a computer to run are the motherboard, hard drive, RAM, and BIOS/CMOS. After assembling the computer, the next step will be obtaining workstations and network servers. For an example the workstations include Windows, Linux, UINX, and Mac OS. The OS is an a very essential because it provides many critical services including a user interface, memory management, file system, and an interface to a computer’s hardware device. To be able to connect to the internet a NIC must be provided. The NIC provides a connection between the computer and the network. After implanting the NIC there will be a need for a network medium, for an example an ethernet cable or a wireless …show more content…

There are broad categories of cables copper wire and fiber optic. The main differences between the two are composition of signals, speed at which signals can be sent, and the distance the signals can effectively travel. There are a lot of things to factor when choosing a network media for an example bandwidth rating, maximum segment length, interference, cable grade, and ease of installation. Now to understand the difference types of cabling. The first one is unshielded twisted-pair cable and are used for most networks. While the shielded twisted-pair cable is used for noisy environments or very high-bandwidth. Lastly is the fiber-optic cable which are bits transmitted as pulses of light instead of electricity. Fiber-optic cables are also immune to electrical interference and high secured. But sometimes wiring isn’t cost efficient so they opted into wireless networking which is a lot more affordable. Not only is it cost efficient it establishes backup or contingency connectivity for existing wired

3. Insulation material: made from XLPE and isolate between the three phases, its thickness is about 5.5 mm along the cable 4. Outer semiconductor: uniformly distribute the voltage on the surface of the insulation 5. Earth layer: made from copper, used to ground the cable, in case of short circuit it protect the cable by leaking the short circuit current into the ground, its thickness is about 25mm2 area 6. Filling: synthetic fibers used to make the cable circular and to fill the gap between the phases 7.

Goals of the Lab This lab has many different overall goals that are meant to introduce us to the challenges and procedures of building a preliminary enterprise environment from the ground up. Each task has it’s own set of goals that expose us to important areas of system administration in this type of environment. The lab first introduces us to installation and configuration of an edge routing device meant to handle all internal network traffic between devices, and allow access out to an external network, in our case the Internet. The lab then introduces installation of an enterprise Linux distribution, Red Hat Enterprise Linux 7, which will be used as the main Linux based server in our enterprise environment.

Understanding networking is a fundamental part of configuring complex environments on the internet. This has implications when trying to communicate between servers efficiently, developing secure network policies, and keeping your nodes organized. Every location or device on a network must be addressable. This is simply a term that means that it can be reached by referencing its designation under a predefined system of addresses. In the normal TCP/IP model of network layering, this is handled on a few different layers, but usually, when we refer to an address on a network, we are talking about an IP address.
