Free Alternative To Microsoft Office

Anyone who ever priced the Microsoft Office Suite knows it represents a significant investment.
A quick check of the CompUSA.com website shows Microsoft Office Standard costs $399 and Microsoft Office Professional will set you back $449. Now, this doesn t discount the value of the software.
In fact, the functionality in MS Office represents the true workhorse of home and small business computing, namely: word processing (Word), spreadsheets (Excel), presentations (PowerPoint), and desktop database applications (Access).
However, with the cost for such functionality at a premium, it comes as no surprise that a viable alternative emerged to challenge Microsoft s position atop the office application market.
OpenOffice.org offers a suite of office software applications free to download for anyone with a computer, including PC s operating with Windows or Linux.
Open Office also offers a free version for Macintosh computers.
Open Office offers its software freely to anyone who wants to download it.
Their all-volunteer organization, sponsored in large part by Sun Microsystems, operates with the noble goal of making productivity software available worldwide in 36 languages, particularly to economies that simply can t afford the cost of other office solutions.
The Open Office software publishes in the Open Document Format to make data universally available (instead of using proprietary file formats that, for instance, make it hard to share between Microsoft Word and Word Perfect).
Open Office contains several main components, each of which help the user with specific tasks.
Writer - This software offers a full-featured word-processing program enabling the user to type letters, brochures, faxes, even entire books. No matter what you need to type, this program lets you do it. It also offers such features as spell check, auto-correction, and thesaurus.
Calc - Calc offers a spreadsheet program enabling the user to create cells containing text or digits, execute simple and complex calculations, database functions, and more. Calc is perfect for accounting spreadsheets, inventory and more.
Impress - Impress enables the user to create "slideshow" presentations containing text and images for use in sales or group presentations. Impress also allows the user to create impressive slide transition effects and eye-catching animation.
Draw - Draw gives the user the ability to create simple to complex drawings using vector graphics. Users can create drawings by hand, or incorporate an array of existing shapes, arrows, lines and other graphics.
Though it does represent an excellent alternative to expensive office software suites, Open Office is not without a few drawbacks.
Since they make the software available free of charge, tech support for the free version only lasts 30 days. Also, by its nature, the software is a "work in progress."
As such, you will find bugs periodically that should get reported to the Open Office website so they can fix them.
However, despite these drawbacks, Open Office software rates a "must look" if you need word processing, spreadsheets and other capabilities we ve naturally come to associate with home and small business computing.

Cisco CCNA Certification Exam Case Study: Frame Relay, Pings, And Routing Protocols

Cisco CCNA certification training includes troubleshooting your own work and that of others. The best CCNA training you can do is indeed troubleshooting your own Cisco router and switch configurations - as I m always telling my students, "I can guarantee that any error you make has been made before, and you ll probably see it again one day." One such common error involves two very important Cisco CCNA certification topics - Frame Relay and routing protocols.

A student was working on her Cisco CCNA exam home lab and came up with an interesting problem. He set Frame Relay up in a hub-and-spoke configuration with R1 as the hub and R2 and R3 as the spokes. He wrote the following frame map statements:

frame-relay map ip 172.12.123.2 122

frame-relay map ip 172.12.123.3 123

He was able to ping both spokes from the hub, so he assumed everything was working correctly. Then he configured RIP version 2 on the router and got the following result after running "debug ip rip" and clearing the routing table with "clear ip route *":

03:33:01: IP: s=172.12.123.1 (local), d=224.0.0.9 (Serial0), len 72, sending broad/multicast

03:33:01: IP: s=172.12.123.1 (local), d=224.0.0.9 (Serial0), len 72, encapsulation failed

You may have already spotted the problem, and if you did, your CCNA certification exam studies are going well! The problem is that the "broadcast" option was left off the frame map statements. "broadcast" must be configured on frame map statements in order to send broadcasts and multicasts across the frame link. As you know from your CCNA certification exam studies, RIP version 1 broadcasts updates and RIP version 2 multicasts them, so the "broadcast" option must be present for either version to send updates by using those frame mappings.

He then rewrote the frame map statements as shown below....

R1(config-if) frame map ip 172.12.123.2 122 broadcast

R1(config-if) frame map ip 172.12.123.3 123 broadcast

.. and the RIP updates went out as expected.

R1 debug ip rip

RIP protocol debugging is on

R1 clear ip route *

06:22:13: RIP: sending general request on Loopback0 to 224.0.0.9

06:22:13: RIP: sending general request on Serial0 to 224.0.0.9

06:22:13: RIP: ignored v2 packet from 1.1.1.1 (sourced from one of our addresses
)

06:22:14: RIP: received v2 update from 172.12.123.3 on Serial0

06:22:14: 1.1.1.1/32 -> 0.0.0.0 in 3 hops

06:22:14: 2.2.2.2/32 -> 0.0.0.0 in 2 hops

06:22:14: 3.3.3.3/32 -> 0.0.0.0 in 1 hops

06:22:14: 172.12.23.0/24 -> 0.0.0.0 in 1 hops

06:22:14: 172.12.123.0/24 -> 0.0.0.0 in 1 hops

06:22:14: RIP: sending v2 update to 224.0.0.9 via Loopback0 (1.1.1.1)

06:22:14: 2.2.2.2/32 -> 0.0.0.0, metric 3, tag 0

06:22:14: 3.3.3.3/32 -> 0.0.0.0, metric 2, tag 0

06:22:14: 172.12.23.0/24 -> 0.0.0.0, metric 2, tag 0

06:22:14: 172.12.123.0/24 -> 0.0.0.0, metric 1, tag 0

06:22:14: RIP: sending v2 update to 224.0.0.9 via Serial0 (172.12.123.1)

Cisco CCNA certification depends on noticing details like these, and there s no better way to learn these details than by working on real Cisco routers and switches. Whether you re renting rack time online or buying used Cisco routers and switches, real-time debugs and configurations are the way to CCNA certification exam success!
