HCI converges the entire datacenter stack, including compute, storage, storage networking, and virtualization. More specifically, it combines commodity datacenter server hardware with locally attached storage devices (spinning disk or flash) and is powered by a distributed software layer to eliminate common pain points associated with legacy infrastructure. Complex and expensive legacy infrastructure is replaced by a distributed platform running on industry-standard commodity servers that enables enterprises to size their workloads precisely and to scale flexibly as needed. Each server, also known as a node, includes x86 processors with SSDs and HDDs. Software running on each node distributes all operating functions across the cluster for superior performance and resilience.
Hubs connect multiple computer networking devices together. A hub also acts as a repeater in that it amplifies signals that deteriorate after traveling long distances over connecting cables. A hub is the simplest in the family of network connecting devices because it connects LAN components with identical protocols.
This section of the website consists of network design proposals. The projects in this section understand different types of computer networking topologies and design network proposals based on the topologies. Different types of sectors like home, office, campus etc are included. The necessary equipments which are required to setup the network, the details related to the IP address design, required applications and services along with a detailed network design diagram is provided.
The network design proposal ebook contains 12 network design proposals reports. Each report contains detailed networking and soltuion explanation, topology diagrams and list of hardware and software. The details of the reports in the ebook is provided below.
This book is organized into the network layers of Internet Protocol Stack which is the base of all computer networking (together with the OSI model), therefore it offers a very good structure and learning experience.
This is one of the most recent (8th edition at the time of this writing) and updated textbooks in this list about computer networking that covers a wide range of topics for both beginners and for seasoned professionals.
Permissions andsecurity are central to the idea of networking: you can access filesand share resources only if someone gives you permission to do so.Most personal computers that connect to the Internet allow outgoingconnections (so you can, theoretically, link to any other computer),but block most incoming connections or prohibit them completely.Servers (the machines on the Internet that hold and serve up Webpages and other files) operate a more relaxed policy to incomingconnections. You've probably heard of hacking, which, in onesense ofthe word, means gaining unauthorized access to a computer network bycracking passwords or defeating other security checks. To make anetwork more secure, you can add a firewall (either a physicaldeviceor a piece of software running on your machine, or both) at the pointwhere your network joints onto another network or the Internet tomonitor and prohibit any unauthorized, incoming access attempts.
Photo: Computer architecture: We can think of computers in layers, from the hardware and the BIOS at the moment to the operating system and applications at the top. We can think of computer networks in a similar way.
Perhaps the best-known way is with what's called the OSI (Open Systems Interconnect) model, based on an internationally agreed set of standards devised by a committee of computer experts and first published in 1984.  It describes a computer network as a stack of seven layers. The lower layers are closest to the computer hardware; the higher levels are closer to human users; and each layer makes possible things that happen at the higher layers:
OSI was conceived as a way of making all kinds of different computers and networks talk to one another, which was a major problem back in the 1960s, 1970s, and 1980s, when virtually all computing hardware was proprietary and one manufacturer's equipment seldom worked with anyone else's.
If you've never heard of the OSI model, that's quite probably because a different way of hooking up the world's computers triumphed over it, delivering the amazing computer network you're using right now: the Internet. The Internet is based on a two-part networking system called TCP/IP in which computers hook up over networks (using what's called TCP, Transmission Control Protocol) to exchange information in packets (using the Internet Protocol, IP). We can understand TCP/IP using four slightly simpler layers, sometimes known as the TCP/IP model (or the DARPA model, for the US government's Defense Advanced Research Projects Agency that sponsored its development):
As we saw above, higher levels of the basic computing models are independent of the lower levels: you can run your Firefox browser on different Windows operating systems or Linux, for example. The same applies to networking models. So you can run many applications using Internet packet switching, from the World Wide Web and email to Skype (VoIP) and Internet TV. And you can hook your computer to the net using WiFi or wired broadband or dialup over a telephone line (different forms of network access). In other words, the higher levels of the model are doing the same jobs even though the lower levels are working differently.
Like highways or railroad lines that connect towns and cities, computer networksare often very elaborate, well-planned things. In the days when computers were big static boxes that never shifted from data centers and desktops, computer networks also tended to be fairly static things; often they didn't change much from one week, month, or year to the next. The Internet, for example, is based ona set of well-defined connections called the Internet backbone including vastsubmarine cables that obviously have to stay in place for years. That's computer networking at one extreme.
Suppose you order a book by mail order and it arrives, a few days later, with the packaging ripped andthe cover slightly creased or torn. That's a kind of error of transmission. Fortunately, since a bookis analog information, a bit of damage to the coverdoesn't stop you appreciating the story the book tells or the information it contains. But what ifyou're downloading an ebook (electronic book) and there's a blip intransmission so some of the data goes astray. Maybe you won't be able to open thebook file at all, rendering the whole thing useless. Or what if a bank is sending an electronic paymentto someone and the data it transmits across its network is corrupted so the account number orthe amount to be paid gets scrambled What if a military control center sends a signal toa nuclear missile installation and a blip on the network alters the data it contains so, insteadof \"power down,\" the rocket is told to \"launch immediately\" The point is a simple one: whenwe send data over computer networks, we need to be absolutely certain that the informationreceived is identical to the information transmitted. But how we can do thiswhen vast amounts of data are being sent around the world all the time 1e1e36bf2d
