Social Network Technology in the Classroom

Considering that today's students were born wired, and live and play in the world of the Web, the challenge for many teachers and administrators is meeting students on their own turf and adapting to the students' medium of choice. Specifically, the emergence of social networks has created a technical gap between teachers, students, and parents unlike any that has previously existed. The need to use technology in the classroom is becoming more important every day. Clearly, social networking will be at the core of any technology that is to succeed in the classroom.

Although some teachers are hesitant to use social networking (also referred to as Web 2.0) - considering privacy issues and a potentially steep learning curve - it's important that they learn to understand and use these tools that are becoming increasingly embedded in the lives of their students.

However, social networks such as MySpace and Facebook are the students' domain, and teachers and parents may not always be welcome. To many of today's students, a teacher socializing on Facebook is the equivalent of having that teacher show up at a weekend party, or at a regular student hangout.

Today's educators need an intuitive, safe, online environment that connects students, teachers, parents, and administrators in a responsible way. One that is geared toward education and one that, while driven by teachers, is open to students, parents, and administrators.

Simply put, they need a social network for the classroom.

In a true Web 2.0 environment, students, parents, and administrators can participate in the teaching process by showing mastery of a specific topic or concept. All parties can interact to ask questions, share knowledge, and relay experiences. The proliferation of ideas never needs to be stagnant. This concept applies not only within a specific classroom, but across all classrooms that can now share a common learning environment - a common social network. To take it a step further, the concept not only applies to all classrooms sharing that same learning environment, but to all classrooms across time.

Consider, as an example, a lesson that was taught in the classroom just ten years ago: The lesson was introduced, a discussion followed, and the lesson ended.

Now, consider that same lesson as it is taught in a Web 2.0 embraced environment: The lesson is introduced, and an online discussion follows. But this discussion includes the viewpoints and experiences of students, teachers, administrators, and parents from around the globe. It will include comments and span new ideas and conversations. It will be supported by images and videos which will also spawn new ideas and conversations.

In addition, this same lesson, when taught the following year, already has the foundation of the previous year's information. The next year builds upon the previous two years, and so on. In the end, we have an ever-growing historical account of the ideas brought about by the lesson - a clearly superior situation to the way it had been taught ten years earlier.

Considering the speed at which technology is evolving, teachers should be encouraged to find and use a social network. One that can be used responsibly and that is geared toward the proliferation of ideas that start in the classroom.

Novell Networking Technologies Exam

Novell Networking Technologies exam (050-632) is a part of the Novell CNE (Certified Networking Engineer) certificate for Novell Netware 5. It covers a wide range of topics that are essential for each and every network engineer or perhaps administrator for Novell, as well as non-Novell networks.

This exam is aimed to cover the following topics:

Topic # Topic Description

1 OSI reference model and physical and logical topologies that are used in computer networks.

2 Functions of networking devices, starting from NICs and up to routers and gateways.

3 IEEE 802.x standards with the concentration on 802.3, 802.3u, and 802.5.

4 FDDI and its devices.

5 WAN technologies; SLIP, PPP, X.25, Frame Relay, ISDN and ATM.

6 Hubs, Bridges, spanning tree, source-routing bridge, and token ring switches.

7 Dynamic routing protocols; distance vector and link state, and nonroutable protocols.

8 IP address structure, network classes, how to obtain a registered IP address, and registering a domain name.

9 Assigning addresses to hosts along with the function of host names, host tables, and DNS.

10 Subnets, supernets and subnet mask.

11 TCP/IP protocol suite.

12 IP routing and disadvantages of RIP and distance vector routing.

13 Link state routing with IP.

14 Using of protocol analyzers in managing a TCP/IP network.

15 IPv6.

16 Internetwork Packet Exchange (IPX) and Sequenced Packet Exchange (SPX).

17 IPX routing protocols RIP and SAP and Link State Routing with IPX NLSP and compare RIP/SAP, NLSP, and OSPF functionality.

18 X.500, and LDAP.

When you go through the list above, the first thing that comes to your mind is Network+. That is right. These topics are very much similar to what Network+ covers. And the fact that Novell would accept Network+ instead of this exam for CNE requirements only assures this idea.

One problem in Novell’s 050-632 [http://www.novell.com/training/testinfo/objectives/565tobj.html] exam is the lack of self-study guides. CramSession offers free exam study guide but its not adequate. It does not cover the whole thing. So, if you are thinking of this exam you might consider taking the course. O perhaps you can read Network+ study-guides and go for Novell’s exam.

You might ask why bother going this road when I can do the Network+ exam which is more popular. I might just have the answer for you. It’s the cost. Novell’s 050-632 exam is about half the price of CompTia’s Network+ !!!

I have always thought of CompTia’s exams as expensive. And I do not believe that making the exams more expensive would increase its value.

Advantages of Leasing Network Technology

Businesses of all sizes are facing up to new challenges in recent times. Most likely your business is feeling the crunch due to the recent economic slump. Now add to the fact that you need to install, or upgrade existing network equipment and that crunch can be even tighter. Don't worry though; leasing network technology may be the answer to your budget problems.

Information technology companies have long been the lead developers of new network systems, and their support systems. Leasing network technology is an idea that's popping up right across the board. It works just like leasing, or renting a car. We all know that building and maintaining your own networks and subsystems can be quite expensive. This type of program allows you to circumvent those costs, and go with an option that's more affordable for you.

Unlike car rentals however, you will never find gum on the technology you lease, and in the off chance you do you might want to let the company know. When companies lease or rent their networking technologies they make sure the equipment is in top condition. After all this is your backbone for a while. Leasing and renting plans differ from place to place, and on what equipment you need.

Leasing network technology is something that's handled with the greatest of care. Many companies offer monthly and yearly plans, some with upgrade options. Renting is essentially a monthly fee, and when you don't need it anymore you return it. Leasing works just like an automobile, you pay a monthly fee for a set time and then are given the option to buy, or upgrade.

Regardless of which path you choose most companies understand you have a limited budget. After all the biggest of the big started out as a small tiny business in an old building. Regardless of the size of your business it's never a bad idea to think about these programs for your network solutions. Have you actually seen the physical components of your network? Chances are no, you let your tech guys handle that.

Trust me it's not pretty, and in some instances it's quite a mess. Even the smallest of networks can have quite a bit of cable and equipment. When leasing network equipment you don't have to worry about setting all of this up, there are installation plans available as well. If you choose this route all you need to do is maintain everything, but if the hardware fails the company takes care of the replacement.

Don't worry technology for servers and other networking equipment has evolved substantially over the years. If the server goes out in most cases you just pull the data tapes, drives, or boards and then slide them into a replacement. No muss, no fuss, and everything works as it should. Yes some severs still use tapes; it's not a dead technology yet.

In closing, leasing network technology is a solution for your networking needs that you might want to look into. After all this can be cheaper than buying and setting up your own equipment. Plus with the ability to buy later on if you so choose, it can be the perfect plan for your business. Now the only thing left to do is think about the size of your desk.
