1: Some of the reasons a website would need to be redesigned is the management system or technology may be out of date, the web designs are probably look old or outdated, website is not mobile friendly, not getting the result you are seeking for, or the business focus change. Technology is always changing and one way to keep the website from being hacked or breached is to keep the website updated. Making sure that the web designs are fresh, contemporary, and looks fresh is the best way to get the user's attention. Having the website improved for mobile devices so that it is easy for the user's to use is important. When people use their mobile devices to browse the internet they want to be able to get to the website quick and easy. When the focus on the business is changing then the website need to change also. I think that it is important to always be planning the next site redesign is because of growth. The way society is growing and changing today it is always best to be prepared.
2: I totally agree that it is necessary for continuous planning of new designs and technologies, as you stated " It's important to make sure your website can be viewed on different devices, such as laptops, desktops, smart phones, and tablets." and this is true, since we've been reading about web design it has caused me to focus a little more on targeted audiences, what appeals to certain groups such moms, teens, other students and various businesses as well as what's trending. And as our needs grow and change so should our designs.
IT/240
1: I have a type of local area network called a home area network in my residence. The high speed internet capabilities we have are provided by our local cable provider. While I have the option to for a wired connection to the modem, it is connected to a router which allows for wireless connectivity to the network on multiple devices as long as the user provides a password to access the network. This is the standard type of network that is installed in one's one private home. It allows for anyone within a reasonable distance from the router to have high speed wireless internet access, which allows for one person to work from home while another person uses the internet from another device without the simultaneous usage interfering with each other. It can also be used to include printers, allowing for content to be printed without a wired connection to the printer, or a shared network storage system that can be accessed by all devices on that particular network.
2:A LAN connects network devices over a (compared to other things) short distance. A networked office building, school, or home usually contains a single LAN, though sometimes one building will contain a few small LANs maybe one per room, and (every once in a while) a LAN will span a group of nearby buildings. In TCP/IP networking, a LAN is often but not always put into use as a single IP subnet. As the term hints, a WAN spans a large physical distance. The Internet is the largest WAN, spanning the Earth. A WAN is a (related to where mountains, rivers, cities, etc., are located)-broke up and moved away collection of LANs. A network device called a router connects LANs to a WAN. In IP networking, the router maintains both a LAN address and a WAN address. A WAN is different from a LAN in (more than two, but not a lot of) important ways. Most WANs (like the Internet) are not owned by any one organization but rather exist under total (of everything or everyone) or distributed ownership and management. In my household our network is LAN, we have it set up this way because my kids all like to play there games online and it seems to work better using it this way. LAN seems to be the general setup when you first install a router to your Internet modem.
