Cutting Down on Hassles With Regular Computer Network Maintenance

As for one true fact, it's impossible to run a computer network without the assistance of significant devices like routers, bridges, gateways, switches, hub as well as some heavy devices like multilayer switches, digital media receiver etc.

However, another fact says that all these mandatory devices cannot function properly 12 months a year, which means that there is a prominent need felt for the computer network maintenance services if one is willing to assure the smooth function of his computer related programs.

With a lot of corporations entering the software and online market, the heavy usage of computers is seen as obvious but, one has to ensure that an IT support system is walking alongside the business to ignore any halt in it.

In the current scenario, a lot ITprofessional companies have analysed the need for their support to the big and small companies present in the segment of the industrialised world, and hence every second day they prepare themselves for a big challenge like shielding system from a new virus, no-hassle how re-assuring system support to a company etc.

The network devices stated above work with the support of each other but, the probability of getting trapped in a hassle system is high here and hence, system support is seen quite in demand in the present times.

As for the experts in the IT world, the computer network maintenance has to be regular in the companies as well as on the individual level, as to wait for some problem to appear can cause danger to the whole system, which falls costly afterward.

Besidesthe common networking devices, a person can also find the trouble in hardware and software components like proxies, firewalls and NATs.

Taking an example of proxy. Here, different systems run with the help of one connection only. However, if the system is not maintained on a proper note, then this could result in the breakdown due to which many systems could get affected as they would be running through proxy.

There are a lot of fields where expert advices means a lot and the segment of computer maintenance is also one of them, so there is no harm in keeping the systems up to date with the help of an assistance.

CCNA Frame Relay Overview Training

As a candidate you CCNA/CCNP are expected to understand

During your career as a Cisco network engineer you will have to deal understanding Frame Relay

Frame Relay is one of the most popular WAN services out there in the real world despite it also being one of the oldest WAN technologies available and there is a very good reason for the continuing popularity of Frame-relay that is down one simple factor which is cost. Anyone building a WAN will generally consider Frame-relay as a viable connectivity option due to the cost alone, WAN's are not cheap by any margin so having Frame-Relay available to connect your different sites together is nice to know.

FR (Frame-Relay) was born out of an older technology called X. 25 which even though is older than FR is still inuse in certain parts of the world. X. 25 was a very robust protocol that had solid error recovery features which were very useful when the network infrastructure was prone to causing transmission errors on the sent date, one major drawback to X. 25 as that due to the constant error recovery features it was very slow.

As time progressed technology improved, at the same there was a requirement for faster transmission speeds from the WAN providers, this lead to the creation of Frame-Relay which on closer inspection operates in much the same way as x. 25 but with out the extensive error detection and correction carried out by x. 25.

By default, Frame Relay is classified as a non-broadcast multi-access (NBMA) network, meaning it doesn't send any broadcasts like RIP updates across thenetwork. No worries-I'm not going leave you hanging. We'll get into this more soon.

Frame relay is a fairly simple protocol to get to grips with, and is taught in the Cisco CCNA course, having said that setting up this technology and configuring it on the router is considerably more complex than setting up PPP or HDLC say which require one command on the serial interface and you're done.

In this technology we need to know the way in which the protocol it's self functions, we need to learn a new addressing scheme and new way in which the Layer 2 addresses are resolved even though frame-relay address resolution does not allow traffic to pass from one site to another like it would in an Ethernet environment.

How to Setup File Sharing in Windows 7

If you have multiple computers at home and want to network them together to share files and devices then this article is for you! In this article I'll show how to setup file sharing in a mixed environment consisting of Windows 7 and Windows XP.

The computer that will be sharing (serving) the files will be the Windows 7 computer. The computer that will be accessing the shared files on the Windows 7 PC will be a Windows xp computer. This article assumes that you either:

A: have your internal software firewalls disabled since they can often obstruct network access. Only do this if you access the internet through a router (or a wireless router).

or

B: know-how to allow network access to your internal subnet. Since you're reading this article it's pretty safe toassume that you have no idea what I'm talking about in point b. Just go ahead and turn off your firewalls (for now at least).

On your Windows 7 computer:

1. Click the Windows globe on the bottom left (the old start button).
2. right-click "Computer" and click properties.
3. Take note of the Workgroup name.

On your Windows XP-based computer:

1. Click Start.
2. right-click "My Computer" and click properties.
3. Click Computer Name.
4. Click Change.
5. Select Workgroup.
6. Type in the same workgroup name.
7. Click Ok twice.
8. Reboot.

Back on your Windows 7 computer lets share your documents folder to everyone in your workgroup:

1. Click Start.
2. Click Computer.
3. On the left window, under libraries, right-clickdocuments and click share with specific people:
4. Click the drop down.
5. Select Everyone.
6. Click Add.
7. Click Read and change it to read/write
8. Click Share
9. Select My Documents
10. Click Next.
11. Sharing your documents may take awhile depending on how many have.
12. Click Done.

Back to your Windows XP PC:

You may now access documents on the Windows 7 computer by

1. Opening your "My Computer".
2. Click "My Network Places" on the left.
3. Click "Entire Network".
4. You should now see the name of your Windows 7 computer.
5. Double click the Windows 7 computer and you'll see any shared files plus any shared devices.
