Breadcrumbs design pattern The user needs to know his location in the website's hierarchical structure in order to possibly browse back to a higher level in the hierarchy. Use when the structure of the website follows a strict hierarchical structure of similar formatted content. Use when the structure of the site is parted in to sections which can be divided into more subsections and so on Use when the user is most likely to have landed on the page from an external source (another site deep linking to the web page in question). For instance from a blog or a search engine. Use when the page in question is placed fairly deep into the hierarchy of pages and when no other form of visual navigation can show the details of the same deep level. Use together with some sort of main navigation.

IPv6 was developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated problem of IPv4 address exhaustion. IPv6 is intended to replace IPv4, which still carries the vast majority of Internet traffic as of 2013. As of February 2014[update], the percentage of users reaching Google services over IPv6 surpassed 3% for the first time. Every device on the Internet is assigned an IP address for identification and location definition.
Pagination design pattern The user needs to view a subset of sorted data that is not easily displayed on one page. Use when there is more data than what is comfortably fitted into one screen. Use when the dataset is ordered into amount of interest (that usually means newest first) Do not use when you don’t want the user to pause for navigating to the next page. Internet Protocol Suite The Internet protocol suite is the computer networking model and set of communications protocols used on the Internet and similar computer networks. It is commonly known as TCP/IP, because its most important protocols, the Transmission Control Protocol (TCP) and the Internet Protocol (IP), were the first networking protocols defined in this standard. Often also called the Internet model, it was originally also known as the DoD model, because the development of the networking model was funded by DARPA, an agency of the United States Department of Defense. TCP/IP provides end-to-end connectivity specifying how data should be packetized, addressed, transmitted, routed and received at the destination. The TCP/IP model and related protocol models are maintained by the Internet Engineering Task Force (IETF). History
Dynamic Host Configuration Protocol The Dynamic Host Configuration Protocol (DHCP) is a standardized network protocol used on Internet Protocol (IP) networks for dynamically distributing network configuration parameters, such as IP addresses for interfaces and services. With DHCP, computers request IP addresses and networking parameters automatically from a DHCP server, reducing the need for a network administrator or a user to configure these settings manually. Overview Computers use the Dynamic Host Configuration Protocol for requesting Internet Protocol parameters from a network server, such as an IP address. The protocol operates based on the client-server model. DHCP is very common in all modern networks ranging in size from home networks to large campus networks and regional Internet service provider networks.
Host (network) Computers participating in networks that use the Internet Protocol Suite may also be called IP hosts. Specifically, computers participating in the Internet are called Internet hosts, sometimes Internet nodes. Internet hosts and other IP hosts have one or more IP addresses assigned to their network interfaces. The addresses are configured either manually by an administrator, automatically at start-up by means of the Dynamic Host Configuration Protocol (DHCP), or by stateless address autoconfiguration methods. Every network host is a physical network node (i.e. a network device), but not every physical network node is a host. Network devices such as modems, hubs and network switches are not assigned host addresses (except sometimes for administrative purposes), and are consequently not considered to be network hosts.
Network switch A network switch (sometimes known as a switching hub) is a computer networking device that is used to connect devices together on a computer network by performing a form of packet switching. A switch is considered more advanced than a hub because a switch will only send a message to the device that needs or requests it, rather than broadcasting the same message out of each of its ports. Overview A switch is a device used on a computer network to physically connect devices together.
Internet 2012 in numbers Posted in Tech blog on January 16th, 2013 by Pingdom There is so much happening on the Internet during a year that it’s impossible to capture it all in a blog post, but we’re going to give it a shot anyway. How many emails were sent during 2012? How many domains are there? What’s the most popular web browser? IPv4 Internet Protocol version 4 (IPv4) is the fourth version in the development of the Internet Protocol (IP) Internet, and routes most traffic on the Internet. However, a successor protocol, IPv6, has been defined and is in various stages of production deployment. IPv4 is described in IETF publication RFC 791 (September 1981), replacing an earlier definition (RFC 760, January 1980). IPv4 is a connectionless protocol for use on packet-switched networks.
Am I addicted to the internet? Maybe, but so what? Every so often, a new study comes out that says people are “addicted” to the internet, or to digital tools, or social media — describing their anguish when cut off from these services in the same way that smokers or alcoholics react when prevented from smoking or drinking. The latest is research from a UK survey company that asked 1,000 respondents to go without internet access for 24 hours, and found that more than half of those surveyed were “upset.” But is this really that surprising?
Syllabus Cisco Certified Architect Certification Observe the definition and responsibilities of the CCAr below, in addition to the CCAr Exam Topics to determine if you are already working at that capacity. Defining the Cisco Certified Architect The CCAr is able to develop and articulate the vision for a network and align the vision with the business’ strategic goals and requirements. The CCAr is able to document the network vision in the form of an architectural specification that guides the technical design for the network. To accomplish these tasks, the CCAr must be adept at discovering business goals and requirements, determining the architectural or functional specifications (e.g., the properties and characteristics of the network) to support those goals, and communicating those decisions and rational to technical and non-technical audiences.
