As an IT Consultant. . .

Take this scenario:

If you were hired by the university president as an IT consultant, what would you suggest (technology, infrastructure, innovations, steps, processes, etc) in order for the internet connectivity be improved?



Razz HOW TO IMPROVE INTERNET CONNECTIVITY?

Connectivity refers to the data or Internet connection whether it is dial-up, dedicated lines, satellite, wireless or other means.

Infrastructure and Networks refer to the computers, peripherals, cameras, hubs, routers, wiring within facilities and network architecture, whether a LAN, WAN or National Grid.


What a Face Growth




Although the basic applications and guidelines that make the Internet possible had existed for almost two decades, the network did not gain a public face until the 1990s. On 6 August 1991, CERN, a pan European organisation for particle research, publicized the new World Wide Web project. The Web was invented by English scientist Tim Berners-Lee in 1989.

An early popular web browser was ViolaWWW, patterned after HyperCard and built using the X Window System. It was eventually replaced in popularity by the Mosaic web browser. In 1993, the National Center for Supercomputing Applications at the University of Illinois released version 1.0 of Mosaic, and by late 1994 there was growing public interest in the previously academic, technical Internet. By 1996 usage of the word Internet had become commonplace, and consequently, so had its use as a synecdoche in reference to the World Wide Web.

Meanwhile, over the course of the decade, the Internet successfully accommodated the majority of previously existing public computer networks (although some networks, such as FidoNet, have remained separate). During the 1990s, it was estimated that the Internet grew by 100 percent per year, with a brief period of explosive growth in 1996 and 1997.

This growth is often attributed to the lack of central administration, which allows organic growth of the network, as well as the non-proprietary open nature of the Internet protocols, which encourages vendor interoperability and prevents any one company from exerting too much control over the network. Using various statistics, Advanced Micro Devices estimated the population of Internet users to be 1.5 billion as of January 2009.

What a Face Technology

The complex communications infrastructure of the Internet consists of its hardware components and a system of software layers that control various aspects of the architecture. While the hardware can often be used to support other software systems, it is the design and the rigorous standardization process of the software architecture that characterizes the Internet and provides the foundation for its scalability and success.

The responsibility for the architectural design of the Internet software systems has been delegated to the Internet Engineering Task Force (IETF).The IETF conducts standard-setting work groups, open to any individual, about the various aspects of Internet architecture. Resulting discussions and final standards are published in a series of publications each of which is called a Request for Comment (RFC), freely available on the IETF web site. The principal methods of networking that enable the Internet are contained in specially designated RFCs that constitute the Internet Standards.

These standards describe a framework known as the Internet Protocol Suite. This is a model architecture that divides methods into a layered system of protocols (RFC 1122, RFC 1123). The layers correspond to the environment or scope in which their services operate. At the top is the Application Layer, the space for the application-specific networking methods used in software applications, e.g., a web browser program, and just below it is the Transport Layer which connects applications on different hosts via the network (e.g., client-server model) with appropriate data exchange methods. Underlying these layers are the actual networking technologies, consisting of two layers.

The Internet Layer enables computers to identify and locate each other via Internet Protocol (IP) addresses, and allows them to connect to one-another via intermediate (transit) networks. Lastly, at the bottom of the architecture, is a software layer that provides connectivity between hosts on the same local network link (therefor called Link Layer), such as a local area network (LAN) or a dial-up connection. The model, also known as TCP/IP, is designed to be independent of the underlying hardware which the model therefore does not concern itself with in any detail. Other models have been developed, such as the Open Systems Interconnection (OSI) model, but they are not compatible in the details of description, nor implementation, but many similarities exist and the TCP/IP protocols are usually included in the discussion of OSI networking.


The most prominent component of the Internet model is the Internet Protocol (IP) which provides addressing systems (IP addresses) for computers on the Internet. IP enables internetworking and essentially establishes the Internet itself. IP Version 4 (IPv4) is the initial version used on the first generation of the today's Internet and is still in dominant use. It was designed to address up to ~4.3 billion (109) Internet hosts. However, the explosive growth of the Internet has led to IPv4 address exhaustion which is estimated to enter its final stage in approximately 2011.

A new protocol version, IPv6, was developed which provides vastly larger addressing capabilities and more efficient routing of Internet traffic. IPv6 is currently in commercial deployment phase around the world and Internet address registries (RIRs) have begun to urge all resource managers to plan rapid adoption and conversion.

IPv6 is not interoperable with IPv4. It essentially establishes a "parallel" version of the Internet not directly accessible with IPv4 software. This means software upgrades or translator facilities are necessary for every networking device that needs to communicate on the IPv6 Internet. Most modern computer operating systems are already converted to operate with both versions of the Internet Protocol. Network infrastructures, however, are still lagging in this development.

Aside from the complex physical connections that make up its infrastructure, the Internet is facilitated by bi- or multi-lateral commercial contracts (e.g., peering agreements), and by technical specifications or protocols that describe how to exchange data over the network. Indeed, the Internet is defined by its interconnections and routing policies.

What a Face Structure

The Internet and its structure have been studied extensively. For example, it has been determined that both the Internet IP routing structure and hypertext links of the World Wide Web are examples of scale-free networks. Similar to the way the commercial Internet providers connect via Internet exchange points, research networks tend to interconnect into large subnetworks such as GEANT, GLORIAD, Internet2 (successor of the Abilene Network), and the UK's national research and education network JANET.

These in turn are built around smaller networks (see also the list of academic computer network organizations). According to a June 2007 article in Discover magazine, the combined weight of all the electrons moved within the Internet in a day is 0.2 millionths of an ounce. Others have estimated this at nearer 2 ounces (50 grams). Computer network diagrams often represent the Internet using a cloud symbol from which network communications pass in and out.

Many computer scientists describe the Internet as a "prime example of a large-scale, highly engineered, yet highly complex system".The Internet is extremely heterogeneous; for instance, data transfer rates and physical characteristics of connections vary widely. The Internet exhibits "emergent phenomena" that depend on its large-scale organization. For example, data transfer rates exhibit temporal self-similarity.

Further adding to the complexity of the Internet is the ability of more than one computer to use the Internet through only one node, thus creating the possibility for a very deep and hierarchical sub-network that can theoretically be extended infinitely (disregarding the programmatic limitations of the IPv4 protocol). Principles of this architecture date back to the 1960s and it might not be a solution best suited to modern needs. Thus, the possibility of developing alternative structures is currently being looked into.

What a Face Connectivity

Common methods of home access include dial-up, landline broadband (over coaxial cable, fiber optic or copper wires), Wi-Fi, satellite and 3G technology cell phones. Public places to use the Internet include libraries and Internet cafes, where computers with Internet connections are available. There are also Internet access points in many public places such as airport halls and coffee shops, in some cases just for brief use while standing. Various terms are used, such as "public Internet kiosk", "public access terminal", and "Web payphone".

Many hotels now also have public terminals, though these are usually fee-based. These terminals are widely accessed for various usage like ticket booking, bank deposit, online payment etc. Wi-Fi provides wireless access to computer networks, and therefore can do so to the Internet itself. Hotspots providing such access include Wi-Fi cafes, where would-be users need to bring their own wireless-enabled devices such as a laptop or PDA. These services may be free to all, free to customers only, or fee-based.

A hotspot need not be limited to a confined location. A whole campus or park, or even an entire city can be enabled. Grassroots efforts have led to wireless community networks. Commercial Wi-Fi services covering large city areas are in place in London, Vienna, Toronto, San Francisco, Philadelphia, Chicago and Pittsburgh. The Internet can then be accessed from such places as a park bench.[19] Apart from Wi-Fi, there have been experiments with proprietary mobile wireless networks like Ricochet, various high-speed data services over cellular phone networks, and fixed wireless services.

High-end mobile phones such as smartphones generally come with Internet access through the phone network. Web browsers such as Opera are available on these advanced handsets, which can also run a wide variety of other Internet software. More mobile phones have Internet access than PCs, though this is not as widely used. An Internet access provider and protocol matrix differentiates the methods used to get online.




Rolling Eyes These are the steps to improve and optimize internet connectivity:


Exclamation Delete windows internet explorer and download Firefox you go to c and then programs and then delete all of the files in the internet explore folder don’t get frustrated because most of the files you deleted will reappear that is caused by another file you did not delete(in the internet explore folder) after you have successfully deleted all of the files in every internet explore folder you can delete the folder and then download Firefox at this link
http://www.filehippo.com/download_firefox/download/fc877e9a730f9480566f5b71bddf812f/ then once you’ve done that when you open up Firefox it will ask you run as default browser click yes and do not show message again then you have to download your plug-in don’t worry its really quick and easy once it says they are done double click one it to finish install here is all the links here is and best of all Firefox is easier to use better faster takes up less space and extremely customizable

Exclamation Do some basic maintenance on your PC. Run Disk Defrag, a scan disk, a virus scan, a malware scan, and clear your recycle bin. An unusually slow Internet connection experience is often the only sign that your computer is infected with viruses or other malware. Delete old files and temporary files. Never allow the free space on your C: drive to be less than 10% of the total size or twice the installed RAM (which ever is larger). A well maintained PC will operate much better than a PC that has never had any maintenance. Google or your local computer repair store should be able to help you with this if you don't know how.

Exclamation Reset Your Home Network. Sometimes restarting your home network if you have one will drastically increase the speed of your connection.

Exclamation Optimize your cache or temporary Internet files. These files improve your Internet connection performance by not downloading the same file over and over. When a web site puts their logo graphic on every page your computer only downloads it when it changes. If you delete the temporary files it must be downloaded again. if you disable the cache, it must be downloaded every time you view a page that uses it. This can be done by opening Internet Explorer, clicking on "Tools" at the top and choosing "Internet Options". On the General tab, click the "Settings" button next to Temporary Internet Files. Set Check for newer versions to "Automatically". Set amount of disk space to use to 2% of your total disk size or 512 MB, which ever is smaller. On Firefox, click "Tools" then "Options," and go to the privacy tab. Then click on the Cache tab within this.

Exclamation Never bypass your router. Most routers include a firewall that is very difficult for hackers to defeat. If you don't need to use Wireless then hook your computer directly to your router. Routers will only slow down your connection by a few Milli-seconds. You won't notice the difference but the hackers will.

Exclamation If you are using a Wireless router, make sure it doesn't conflict with a cordless phone or wireless camera. Wireless routers come in two varieties; 802.11bg (2.4Ghz) or 802.11a (5.8Ghz) If you are using a 2.4Ghz Cordless phone and 2.4Ghz Wireless router then your Internet connection speed will slow while you use the cordless phone. The same is true of wireless security cameras. Check on your phone and camera, if it's 900Mhz then it's fine. If it says 2.4Ghz or 5.8Ghz then it could be the cause of your slow connection speed while they're in use.

Exclamation Call your Internet service provider (ISP). Sometimes you just have bad service. They can usually tell if your connection is substandard without having a technician come to your home. Just be nice and ask.

Exclamation Upgrade your computer. If your computer is slow, it doesn't matter how fast your Internet connection is, the whole thing will just seem slow. You can only access the Internet as fast as your PC will allow you to.

Exclamation Replace your old cable modem. Any solid-state electronics will degrade over time due to accumulated heat damage. Your broadband modem will have a harder and harder time 'concentrating' on maintaining a good connection as it gets older (signal to noise ratios will go down, and the number of resend requests for the same packet will go up). An after-market cable modem as opposed to a cable-company modem will frequently offer a better connection.

Exclamation Often your connection speed is slow because other programs are using it. To test if other programs are accessing the Internet without your knowing, Click Start, Click Run. Type "cmd" (without quotes). Type "netstat -b 5 > activity.txt". After a minute or so, hold down Ctrl and press C. This has created a file with a list of all programs using your Internet connection. Type activity.txt to open the file and view the program list. Ctrl Alt Delete and open up the Task Manager. Go to the process menu and delete those processes that are stealing your valuable bandwidth. (NOTE: Deleting processes may cause certain programs to not function properly)

No No After you have tried all this try your connection again and see if it's running any faster.


Tips

•Call your ISP and have them verify all of your TCP/IP settings if you are concerned. Ask them to verify that your Proxy settings are correct.

•Don't expect dial up or high speed lite service to be fast. The Internet is primarily geared towards Broadband Connections. Sometimes, you have to wait a little.

•Download programs that make browsing faster:

•Loband.org is a browser inside of a browser that loads web pages without the images.

•Firefox and Opera both have options to disable images.

•In Firefox, you can also use extensions such as NoScript that let you block scripts and plug-ins that would otherwise slow things down a lot.

•If you are using Internet Explorer or Firefox, try downloading Google Web Accelerator. It is meant to speed up broadband connections, but it can also slow your Internet connection. Try enabling it and disabling it and see when your Internet connection runs faster.

•If you are using Firefox, download the Fasterfox extension and Firetune.

•Reduce the amount of programs running that use your Internet connection (Instant Messengers, RSS Feeders, and MS Applications set to send Internet data)

•Google Accessible Is designed to search pages in order of how clean they are of junk. This will bring up pages that are usually not only easy to read, but are quick to load.
•Upgrade your RAM. This will not only improve your regular computer use, but it will affect the speed of your Internet connection because your computer works faster.

•Use the Stop button to stop loading pages once you've gotten what you want.

•Some times malware on your computer can eat up your bandwidth. Make sure you have an up-to-date malware protection program.

•Most Internet Providers have flaky DNS servers (no citation necessary, it's a given) - so, instead of using those provided by your ISP, switch your DNS servers to use those of OpenDNS. OpenDNS is far faster, and more reliable, simply using 208.67.222.222 and 208.67.220.220 as your domain name servers will speed up most flaky DNS problems (may even speed up your networking since OpenDNS has large caches).

•Look into running your own local DNS server on your network. Some newer routers may include their own nameserver, otherwise, check into AnalogX.com's DNSCache program, it works great to hold commonly accessed domain names in the "cache" so that the IP addresses do not have to be looked up every time you navigate to a new page.

Exclamation Exclamation Warnings Exclamation Exclamation

•Viruses and malware can often use up your bandwidth and slow down your Internet connection. Make sure you have protection against this. Many ISP's will provide software for this. Make sure your anti-virus and malware scanners are up-to-date.

•Bypassing the router will leave you more vulnerable to attacks because you no longer have the built-in firewall from your router protecting you.

•Watch out for scams that claim to make your Internet go a lot faster for free. They may tell you to download their program, which usually has a lot of other hidden programs attached that might steal your identity.

Much like organic viruses found in the real world, computer viruses, which are malicious programs, are just as crafty and can greatly damage your computer system, starting from slowing it down considerably to making it crash. Protecting your computer from malicious attacks is therefore of vital importance and even more so if you use the Internet on a regular basis.

Although you may religiously follow the golden rule of not downloading anything from strange websites or opening unknown attachments, there is always a chance of viruses sneaking into your system without you being aware of it. Also, with the increased incidence of flash memory drives being used as portable devices for storing and sharing data, the chances of a virus infection become even more pronounced.

A virus present in your friend’s flash drive can easily be transferred to your computer when you plug it in. Thus there arises a need for anti virus software that will monitor your system on a regular basis, checking for virus attacks.

Some of the well-known commercial anti virus software include the ESET Nod32 Antivirus 4, the Norton Antivirus 2009, Kaspersky Anti-virus 2009, Panda Antivirus Pro 2009, AVG and the BitDefender Antivirus 2009 to name a few. Ideally, anti virus programs should come with the ability to detect a wide range of viruses and the manufacturing company should come up with regular updates. Getting updates on a regular basis is an extremely important factor as new viruses are created on a daily basis.

Now the ESET Nod32 Antivirus 4 is quite a well-rated commercial anti virus software that is fast and light while protecting against a host of malware. One of the highlights of this anti virus program is the use of its ThreatSense technology which comes is very handy as it can help ward off attacks from even new viruses.

Norton Antivirus 2009 is another commercial anti virus software that is widely used and protects your computer from a wide range of viruses, worms, rootkits and other infective agents. You can also get “rapid pulse” updates after every five to fifteen minutes. However, the flipside to using Norton is that you would have to pay for any technical support that you may require.

The Kasperky Anti-virus 2009, which is a little more expensive than other anti virus programs, is quite a force to reckon with when it comes to virus protection. The software is fast and easy to use while detecting viruses, both known and unknown present even in user applications. It also has built-in system restoration capabilities along with automatic updates.

The Panda Antivirus Pro 2009 is another solid anti virus program that has an “ultrafast scan engine” which along with viruses, also detects and removes rootkits. The BitDefender Antivirus 2009 is another impressive anti virus program which uses minimal computer resources while protecting your system from malware with 96% accuracy. AVG Antivirus is another reputed antivirus and antispyware program which has real-time virus protection and also has a free edition for home use.
