Microsoft Office documents store results of many hours, days or even years of work of practically all office employees and most people who use their computers at home. Microsoft Word dominates the market of word processors, and most if not all documents are stored in RTF and its proprietary DOC formats. Microsoft Excel and its XLS file format dominate spreadsheet market. Most presentations are created in Microsoft PowerPoint and stored in PPT files, and most charts and drawings are drawn in Microsoft Visio and saved as VSD files. Combined, files in these formats occupy significant space on the users’ hard drives, and represent hours and hours of work, much more than any other file format.

In an unfortunate case of hard disk crash or file system failure, what would you try to recover the hardest? Would it be a set of software products such as Windows or Office itself, which you can easily re-install from the original CD or DVD, or would it be files and documents you spent your personal time working on? Unless you have a fresh backup of your documents somewhere, the documents are impossible to simply re-install. If you have a recent copy of your Office documents, that’s great! But what if your backup is several days old, and you’ve put a lot of work into these documents? Or even worse, what if you don’t have a backup at all?

Recover latest versions of your deleted documents even after a hard drive failure with DiskInternals Office Recovery securely and reliably. Unlike general-use undelete and data recovery tools, DiskInternals Office Recovery strongly benefits from being designed specifically to handle documents stored in Microsoft Office format.

General-use recovery products scan the computer’s file system in order to locate files that were deleted or corrupt because of a hard drive failure. However, they frequently fail to work properly if the file system itself is damaged, which happens a lot after hard drive failures.

DiskInternals Office Recovery scans entire surface of your hard drive in order to locate all Microsoft Office documents that are still there. In order to find the documents, it uses a set of signatures that are characteristic for the Office file types. The file system is also scanned in order to retrieve the names of the files. The results of disk scan are matched against information contained in the file system, and you are presented with a complete list of all Microsoft Office documents that are on the disk and that are still possible to recover.

Quite often you don’t want to see the list of all Microsoft Office documents that were ever saved on your computer. There’s no point in spending time scrolling through an endless list of files if you just need the latest revision of a PPT presentation or an XLS spreadsheet, but you need that document right away. DiskInternals Office Recovery offers an extensive set of filters allowing you to display only the files that you need with just a few mouse clicks. If you need a DOC file that you know you worked with today, you simply activate the File Format and Date filters, and only the Word documents that were modified on this day will be displayed. If you don’t remember the name of the file, but know its title or the person who created the document, the Title and Author filters will show you those files. Similarly, if you only remember a line or even a few words of text from the document, you can instantly locate that particular file by activating the Text filter.

With full document preview in the free evaluation version, there are no worries or surprises in buying DiskInternals Office Recovery. Download the free trial version from http://www.diskinternals.com/ and see for yourself that it is fully capable to do the job!

A popular method of doing this is using PPP callback, but as we all know, it’s a good idea to know more than one way to do things in Cisco World! A lesser-known but still effective method of callback is Caller ID Screening & Callback. Before we look at the callback feature, though, we need to know what Caller ID Screening is in the first place!

This feature is often referred to simply as “Caller ID”, which can be a little misleading if you’ve never seen this service in operation before. To most of us, Caller ID is a phone service that displays the source phone number of an incoming call. Caller ID Screening has a different meaning, though. Caller ID Screening on a Cisco router is really another kind of password – it defines the phone numbers that are allowed to call the router.

The list of acceptable source phone numbers is created with the isdn caller command. Luckily for us, this command allows the use of x to specify a wildcard number. The command isdn caller 555xxxx results in calls being accepted from any 7-digit phone number beginning with 555, and rejected in all other cases. We’ll configure R2 to do just that and then send a ping from R1 to R2. To see the results of the Caller ID Screening, debug dialer will be run on R1 before sending the ping. Ive edited this output, since the output you see here will be repeated fire times once for each ping packet.

R2(config-if)#isdn caller 555xxxx

R1#debug dialer

Dial on demand events debugging is on

R1#ping 172.12.12.2

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 172.12.12.2, timeout is 2 seconds:

03:30:25: BR0 DDR: Dialing cause ip (s=172.12.12.1, d=172.12.12.2)

03:30:25: BR0 DDR: Attempting to dial 8358662.

Success rate is 0 percent (0/5)

R1 doesn’t give us any hints as to what the problem is, but we can see that the pings definitely aren’t going through. On R2, show dialer displays the number of screened calls.

R2#show dialer

BRI0 – dialer type = ISDN

Dial String Successes Failures Last DNIS Last status

8358661 1 0 00:03:16 successful

7 incoming call(s) have been screened.

0 incoming call(s) rejected for callback.

The callback option mentioned in the last line shown above enables the router to reject a phone call, and then call that router back seconds later.

R2 will now be configured to initially hang up on R1, and then call R1 back.

R2(config-if)#isdn caller 8358661 callback

R1 will now ping R2. The pings aren’t returned, but seconds later R2 calls R1 back.

R1#ping 172.12.12.2

Success rate is 0 percent (0/5)

R1#

03:48:12: BRI0: wait for isdn carrier timeout, call id=0×8023

R1#

03:48:18: %LINK-3-UPDOWN: Interface BRI0:1, changed state to up

R1#

03:48:18: BR0:1 DDR: dialer protocol up

R1#

03:48:19: %LINEPROTO-5-UPDOWN: Line protocol on Interface BRI0:1, changed state to up

R1#

03:48:24: %ISDN-6-CONNECT: Interface BRI0:1 is now connected to 8358662 R2

show dialer on R2 shows the reason for the call to R1 is a callback return call.

R2#show dialer

BRI0 – dialer type = ISDN

Dial String Successes Failures Last DNIS Last status

8358661 3 0 00:00:48 successful

7 incoming call(s) have been screened.

10 incoming call(s) rejected for callback.

BRI0:1 – dialer type = ISDN

Idle timer (120 secs), Fast idle timer (20 secs)

Wait for carrier (30 secs), Re-enable (15 secs)

Dialer state is data link layer up

Dial reason: Callback return call

Time until disconnect 71 secs

Connected to 8358661 (R1)

The drawback to Caller ID Callback is that not all telco switches support it, so if you have the choice between this and PPP Callback, you’re probably better off with PPP Callback. However, it’s always a good idea to know more than one way to get things done with Cisco!

ATSC Standards is a digital television format which will in the long term replace the current NTSC television system, as is the case in United States by February 17, 2009 and in Canada by August 31, 2011. These new high definition standards produce a display resolution better than approximately six times its predecessor it shows off a lucrative 16:9 wide screen images up to 1920×1080 pixels in size. Not to forget, other different image sizes are still supported so that a maximum of six standard definition channels can still be broadcasted.

Sound wise, the ATSC is capable of a theater quality audio as it adopts the Dolby Digital AC-3 format, which also produces the 5.1 channel surround sound.

When broadcasting with the ATSC and an analog signal, two separate channels are required as the ATSC requires an entire channel for itself. As virtual channels can be remapped to any other number from 1 to 99, ATSC stations will often associate with one of the NTSC channels or all stations will use the same number.

Also, like many other systems, the ATSC is an interwoven standard, and is also heavily patented as it includes elements from MPEG, AC-3 audio coding, and the 8VSB modulation.

Comparison with Other Standards
Nowadays, the ATSC system, despite previously being criticized as being too complicated for the ordinary and over-priced to be a household system, is relatively simplified and is moderately priced compared to the current worlds most used system, the DVB.

Also, the ATSC signal, ironically, is more capable of adopting the changes in radio propagation conditions compared to the likes of DVB-T and ISDB-T. Were the ATSC capable of changing its parts such as its error correction modes, code rates, the randomizer, and the interleaver mode, it could become even more robust. Regardless of such fixed settings, it still is sturdy under various conditions.

So what’s so great about USB flash drives?

Small

Prior to the creation of USB flash drives all external storage devices for computers were either bulky or awkward (dozens of blank discs for example) or sometimes an annoying combination of being both bulky and awkward. USB flash drives are also called Thumb Drives because they’re about the size of your thumb (although some are much smaller now) and you can easily fit several gigabytes of data in your jeans or shirt pocket thus eliminating the bulky and awkward factor straight away.

Portable

USB flash drives are about the single most portable data backup device possible. They don’t require an external power source of any kind, nor do you need any cables or tools to set them up and last but not least they don’t require any additional software to be installed for them to work on any modern computer (Windows XP, 2000 and Vista and most Macs) so you can quite literally pick them up and use them anywhere you want.

Reliable

Once the data is stored on a USB flash drive you can rest assured that it’s going to stay there and be there when you next need it. This is totally unlike the world of floppy disks or rewriteable CD/DVD discs where they can just stop working for no apparent reason. Flash drives were built to provide consistent and reliable performance. Most of these drives come with built-in write protection to prevent you from overwriting your own important data – if you were silly enough to do so.

Tough

For years people fiddled with boxes of floppy disks and CDs/DVDs. These were bulky, easily lost and easily damaged. External hard drives also provided another method of transporting data between systems but the smallest jolt was and is enough to kill an external hard disk stone dead. USB flash drives are based on what’s called Solid State Memory – this simply means that it’s the same as standard computer memory in that it has no moving parts and is therefore almost impossible to damage (except for jumping up and down on it or maybe hitting it with a hammer for example. Please don’t test either of these theories at home!)

Mass Storage

The first USB thumb drives only offered between 16MB and 64MB of storage space. The incredible popularity of these drives has driven the desire for more and more storage space to new heights every few months. Currently 8GB USB drives are becoming pretty common and it won’t be long before the 12GB and 24GB models hit the market. To put this in perspective 8GB is enough to hold 2 full DVD quality movies or about 2,700 high quality MP3 files – surely this is enough for you? No?

The portability of the USB flash drive combined with reliability and the more than generous storage provided by such a tiny device make them the smart choice for anyone who needs to move files between PCs or simply just keep a second copy of their most precious data on a secure and reliable storage device.

Norton Anti-virus

Symantec’s Norton AntiVirus software is perhaps the world’s most trusted antivirus solution. It is available for both Windows PC’s, and Macintosh (Symantec Antivirus for Macintosh – S.A.M). Norton AntiVirus is a very reliable and easy-to-use anti-virus product. It’s the best anti-virus product for catching viruses in downloaded files and E-mail. Norton AntiVirus is also more expensive than McAfee VirusScan although not by much, and the added abilities of Norton can easily make up the difference.

Norton AntiVirus includes many tools that can be run in the background, including watching for suspicious PC activity and automatically checking downloaded files for viruses. Norton AntiVirus is also automatically configured to handle E-mail virus scanning for email messages coming into your computer, as well as those you send. This process automatically scans and cleans both incoming and outgoing email, stopping viruses from infecting your computer or spreading to others. It removes viruses automatically, without interrupting your work and prevents infections during real-time online chats, and also detects viruses in instant-message attachments. Because so many viruses and internet worms are now spread using email and Instant Message Systems, this is extremely valuable and necessary protection.

Norton Installation

Installation is simple. Simply install the CD in your CD drive, and the installer will launch automatically. The installer should ask you if you want to do a pre-install scan of your system for viruses. This is a very good thing to do. Once this is finished, the installation will proceed, and you can accept all the defaults without worry. Once the installation is complete, you’ll be prompted to go online and get up-to-date virus definitions. DO NOT skip this step. Having up-to-date virus definitions is essential to the performance of any antivirus software.

Normal Use

Norton is a very hands-off program. Pretty much it is an install and forget program that looks after itself. It will automatically notify you if there is anything that you need to do. If a virus is found, the software will try to automatically repair the file, if it can’t, it will place the file in a safe ‘quarantine’ zone, and let you know. In addition to looking for known viruses, the Norton Antivirus Bloodhound feature tries to spot new viruses and worms by their behaviour that is common to such nasty programs.

Checking your system and downloading updates are two things you need to do regularly. Norton Antivirus makes them painless by setting up a full system scan once a week and checking for new updates (both to the software, and virus definitions) whenever you’re online. These simple update scans hardly slow down your PC down at all.

Overall, Norton Antivirus is an excellent way to guard against viruses. It is the system that I recommend to my clients most often, and that I use personally.

On the Internet, companies come in every size, too, from a stand-alone ebook sales page with webmaster and owner all in one, to 300 pound gorilla like Amazon, with over a million pages, who requires the entire population of a small country to serve as webmaster.

If your site is a single page, it is its own network. But if your site is any bigger, and you have plans to grow, it is a network or is fast becoming one. You need network monitoring.

Most ecommerce webmasters are at least somewhat familiar with website monitoring. Many use a website monitoring service or software to keep track of “uptime” and “downtime”.

At your local shopping mall, serious business requires more than just knowing when the front doors are open and when they are closed. Serious ecommerce needs to know more than just when the site is accessible. That is what network monitoring is all about.

DNS servers: These are used to translate your site name, like www.URL.com, to the numbers called “IP addresses” that computers understand. If DNS servers are not working properly, end-users will not be able to find your site and will get an error. Usually only an external or remote monitoring service will detect such a problem.

An FTP server: File Transfer Protocol servers are used to help you
exchange files with remote users. If you use FTP, a monitoring
service can make sure it is always up and running.

POP3 and SMTP servers: These are used for exchanging emails. If you are using email, chances are you are using SMTP and POP3. If your SMTP server is down, everyone who sends you email will receive an error, stating that your mail server is down and cannot accept incoming email. To say that the impression this leaves your customers is bad would be an understatement. If your POP3 server is down, you will be unable to retrieve email from your mailbox. Once again, only external monitoring will prevent such a problem.

Firewalls: Many businesses use firewalls to protect their internal network from un-authorized traffic, such as spyware, viruses and sabotage by competitors. Furthermore, a firewall is your first line of defense. If your firewall goes down, your whole network may actually become inaccessible from outside. In other words, if you host your own web site and mail servers, those will become
inaccessible to the outside world if your firewall goes down. Once again, remote network monitoring is required to detect that a problem exists and quickly get it repaired.

Internet connections: Users come to your network from multiple backbones, depending on the company they use to connect to the Internet and their location. It is important to insure that your connection performs well for each user. A remote monitoring service can ping your networks from multiple locations around the world, thus testing most major routes to your web server or network. Before hiring a network monitoring service, check to see that they have both your customer geography and the Internet backbone layout covered.

Very few websites of any size and functionality are anything less than a complete network, and many networks rely on servers in different parts of the world.

A good network monitoring service can ensure, as a base, that all servers are properly functioning, that data can be sent to and received from each server, and that each function sharing the server responds as required. An advanced network monitoring service can even remotely monitor the temperature of your servers.

What you need to monitor depends on how extensive your network is. A network monitoring expert can help you determine what needs monitoring. If you own the servers, or are remotely hosted on dedicated servers, you most likely need everything monitored. If your site is hosted on shared servers, you might need fewer functions monitored.

If you did, you would quickly realize what a difference computer keyboards can make to a typing experience. It took me a couple of years to realize that there were actuallly a lot of options when it comes to computer keyboards and that I didn’t have to be satisfied with a computer keyboard that didn’t fit my hands.

I have probably made my way through at least eight or nine computer keyboards in the past ten years. I have learned what suites my body and my needs better and that has often caused me to go on the hunt for a newer and better computer keyboard. I have learned that there are a huge variety ofAs computer keyboards and that if you search for them, they do not have to be too expensive or hard to find.

If you are about to purchase a computer for the first time, or if you are simply looking for a computer keyboard that fits your body and your needs better, then don’t rush into a purchase until you have done some research to learn about your options. A great place to begin the search for computer keyboards or any other part of computers is by visiting a computer store where the employees are knowledgable about all things computer. Stop into a local store or two and see what you can learn about choosing computer keyboards that are right for you.

Another great way to do research on computer keyboards is online. That is, if you can manage to use your current keyboard for a few hours to do the research! Look through many websites until you find the deals that are in your budget and that match your needs. Finding a computer keyboard can be a tedious process, or it can be easy if you look in the right places. The bottom line is that if you are going to be using your computer a lot, then it pays to have the best possible computer keyboard.

Avoid Buying From Offline Retailers

One of the most worst things you can do as a consumer is to buy games, especially if they are not new, from a local retail outlet. Most of the games within these stores are overpriced even after you factor in the discount that you will get from the advertised sale price or the savings through the store’s discount card. If you have too, then its best to buy a game from the pre-owned section. Pre-owned games are generally in good condition and cost 20 % less then their counterparts, just remember to inspect the game box for any missing game manuals and the game disc for scratches.

Search For Online Deals

As a consumer your first choice should be eBay. Generally used games on eBay are much cheaper than the major retailer’s pre-owned selection and occasionally you do find good deals. Instead of bidding on a single title you should instead try to win a lot of 10 to 50 games. Keep the games that you need from the lot and auction off the rest. Lots are generally more cheaper, on a per game bases, and in my experience these sellers do not gouge buyers on shipping costs. Also when using eBay be sure to use Paypal as the payment option. Paypal issues, several times during the year, coupons which can be used when paying for eBay items, these coupons offer an additional saving of 5 10% and are usually found in eBay’s monthly newsletters. There are also online sites such as pricegrabber.com and dealrush.com that display weekly deals from all the major video game retailers. An advantage to using these sites is that they are updated daily meaning you can stop having to rely on the Sunday flyers to find deals. Apart from these sites you can also save money by purchasing used games from members on the various gaming forums (such as cheapassgamer.com) that you may participate in. Just be sure that the forum members that you trade with have a high iTrader rating.

Have Patience

Game prices fall dramatically within a span of four months. Therefore, you should consider waiting a couple of months before buying a new game. Apart from saving you money this approach also allows you to get a better idea of how good the game is and if its worth owning.

Rent If Broke

So why should you rent games? Because its cheap and it provides you the ability to test new games. Most of the latest games appear on the renting shelves within the first two weeks of the initial release date, and given that most major retailers charge only $4-$8 for a game rental, this is the perfect opportunity to test, review and hopefully finish the game. Renting works especially well if you just need to play the latest games without caring too much about owning a personal copy. Remember, you can always buy your favorite rented games later on in the year when they cost a fraction of the original price.

Sell Your Games After You Finish Them

As a broke gamer the worst thing you could is start a collection, especially with new releases. Most new games fall dramatically in price within the first few months, so its vital that you sell your new games as soon as possible. Remember, you can always rent games, either when company comes over or at times when you are bored. This method will not only provide you with additional revenue but will also insure that you are able to play the latest releases.

For your Cisco home lab, one important cable is the DTE/DCE cable. These cables have two major uses in a home lab. To practice directly connecting Cisco routers via Serial interfaces (an important CCNA skill), you’ll need to connect them with a DTE/DCE cable. Second, if you plan on having a Cisco router act as a frame relay switch in your lab, you’ll need multiple DTE/DCE cables to do so. (Visit my website’s Home Lab Help section for a sample Frame Relay switch configuration.)

If you have multiple switches in your lab, that’s great, because you’ll be able to get a lot of spanning tree protocol (STP) work in as well as creating Etherchannels. To connect your switches, you’ll need crossover cables.

You’ll need some straight-through cables as well to connect your routers to the switches.

Finally, if you’re lucky enough to have an access server as part of your lab, you’ll need an octal cable to connect your AS to the other routers and switches in your lab. The octal cable has one large connector on one end and eight numbered RJ-45 connectors on the other end. The large connector should be attached to the async port on your AS, and the numbered RJ-45 connectors will be connected to the console ports on your other routers and switches.

Choosing and connecting the right cables for your Cisco CCNA / CCNP home lab is a great learning experience, and it’s also an important part of your Cisco education. After all, all great networks and home labs all begin at Layer One of the OSI model!
