Choosing the Right Network for Your Business

When it comes to networks, the technology that is really helping to innovate is not something shiny and new, but rather something over twice as old as we are: Ethernet. But with age comes respect, and the Ethernet protocol is widely respected and used by almost all computer and networking vendors.

Ethernet allows for vast packets of information to be sent over networks. Originally these networks were Local Area Networks (LAN) – carrying information around a single building – but now the Ethernet protocol can be used to send information over an entire Metropolitan Area Network (MAN) or over a Wide Area Network (WAN).

MANs and WANs

If the servers you wish to network all reside in the same town or city then you will most likely want to invest in a Metropolitan Area Network (MAN). If your data centres or servers are within a few kilometres of one another, dark fibre and/or Ethernet Private Lines (EPL) can be installed to deliver high-speed, low latency network performance. It will cost a little more and you will have to be careful to obtain the right contract type, but it delivers unbeatable speeds across a relatively small area.

If, however, you need to connect data centres, offices and servers across an entire country, or even internationally, then you should look toward Wide Area Networks (WAN). Most WANs will use a MPLS IP VPN (multi-protocol label switching Internet Protocol virtual private network). This sounds complex, but in essence it is like sending information securely between LANs in different areas over a virtual private network (VPN).

As you may expect, sending information over such wide areas and routing it through a number of server farms takes significantly longer, and therefore WANs cannot match the speed of a MAN. However, it is much more flexible allowing for multi-office networks internationally as well as flexible-working options.

Each network type has different benefits and drawbacks and requires different components, so when it comes to deciding on a network infrastructure for your business it is important to carefully consider a few things first. You need to consider your network requirements in terms of location, speed, carrier and cost.

Location

In the unlikely event that all your computers and staff are located in the same building you can simply use a LAN. This is what Ethernet was designed for and will deliver the highest speeds and most reliable connection.

However, most businesses now have offices/staff and computers/servers/data centres in different clusters across the country or even internationally. These are often supported by single building LANs connected to other nearby units over a MAN, which may then be connected with other clusters over a WAN.

This may sound straightforward enough, but when you consider that this set-up must run over a number of network carriers using an amalgamation of very specific technologies, you may start to realise the difficulties in managing your network. If you need this kind of set-up, make sure you find a specialist partner with a deep knowledge and expertise to help you.

Speed

When it comes to the speed of your network you must ultimately balance probable latency with acceptable latency, cost with time, and peak demands with capacity purchase.

It is a difficult balance to find, especially when your business relies on continuous network access and good transfer speeds. If you are struggling to balance all these factors, we recommend choosing a specialist partner to help you out.

Carrier

When piecing together a new network, or expanding a current one, it is important to be aware not only of differences between technologies, but also differences between carrier capabilities.

Most network providers will advocate IP VPNs for the best enterprise-grade service, but these require different transport and access technologies. Order the wrong piece of kit for the job and you will find yourself wasting vast amounts of time and money.

Cost

Along with technologies, you must also invest in the right service and capacity – right both for your current and your foreseeable requirements. This can be an immensely difficult task to get right the first time around, but if you don’t get it right you will be wasting time and money, not to mention the high-chance of creating a very disjointed network.

Ultimately you must find a balance between cost and capacity while allowing for a fair amount of future flexibility.

How To Select The Right Computer Network Solutions For IT Services

There will always be something new to deal with when you have a network of computers in your business. Whether you have three or thirty work stations, if there is a virus in your system, or when something goes wrong, you will want it fixed as soon as possible. If left unattended, a small problem in your network can easily escalate into a crisis, paralyzing the entire business. The right tech support company should acknowledge how frantic you can feel when your business is grounded to a halt because of a breakdown in the network.

A good network solution provider should work hard to minimize inconveniences that are prompted by network failures. But, how do you find the right computer network solutions for your business?

The first consideration that you need to make when searching for a computer network solution is the provider’s ability to deliver a service that suits your business’ needs. Never get hypnotized by the sales messages before understanding the nature of the network solution offered by the company. You need to be aware of your business’ IT requirements before searching for solutions that will meet these requirements.

The other consideration that you need to make is the efficiency of the network solution. Never overlook information about the latest network specifications for your desired service. In addition, ensure that the network company has the latest infrastructure to deliver what you are looking for. You might want to contact the service provider’s customers for an interview on their experience with the company.

Time is of great essence in the business world. Thus, a network support solution should have the right equipment to respond to any emergency that you may experience in your computer network. A cutting edge server and network support solution should also ensure that your network performs at its peak while resolving any maintenance issues efficiently through a series of proven methodologies. As a dedicated network solution, the service provider should also ensure that your network is secured against internal and external security threats.

The service level is another important factor that you need to consider when selecting the right network solution for your business. You want a service provider that offers a professional service without straining your budget. In addition, the provider should be able to provide training to your staff on how to use your business network in an efficient manner. It would be great if the network solution you settle for is capable of responding to your business’ growing needs.

Finally, the cost of the network solution is another important consideration that you need to make. While this should not be the sole determining factor, you need to ensure that you get value for your money. Before contracting any network service provider, be sure to do your research in order to have an idea of the average market rates for this service.

What Has Really Changed in CompTIA Network+ Exam N10-005? An Overview

Anyone who is aspired to get into the field of computer networking, CompTIA Network+ certification is a great support. Attaining CompTIA Network + training and there upon a certification is a starting point for the aspired candidates those who are looking forward to achieve other high end networking certification tracks, which especially do not have a specific certification exam that covers basic networking hardware and TCP/IP etc.

Recently, CompTIA has changed its CompTIA Network+ exam look, and it is to be changed from N10-004 to N10-005. CompTIA Network+ is a mid-level certification for network technicians, designed to test the competency of a mid- level network technician in supporting and configuring TCP/IP clients in terms of network design, cabling, hardware setup, configuration, installation, support and troubleshooting.

The CompTIA Network+ certification exam invariably test the ability of a networking technician to install, maintain, troubleshoot and support a network and understand the various aspect of networking technologies including TCP/IP and the OSI model. Although, the test still cover these areas and also test the knowledge of network component and where they function in association with the OSI model, network cabling, network security and network troubleshooting.

So what are the exact changes in the CompTIA Network+ exam – N10-005?
The new Network+ N10-005 exam is a 90 minutes exam consists of 100 questions. These questions are in multiple choice formats, and mostly with one correct answer. There are often cases wherein multiple accurate selections can be considered. One requires scoring 720 points out of possible 100-900 points. It is considered as an additive test where one gain points for correct answers but there is no penalty for wrong answers. All these mentioned aspects are the same as before (similar to N10-004).

The change is in the fact that before, no actual pre-requisite requirements are needed to get qualified to take the exam. However, now CompTIA recommends CompTIA A+ certification and 9 months of computer network related experience.

No significant changes have happened, however it cannot be said that there are no changes at all, not drastic changes for sure in focus or in content. Many new items are either obvious or direct elements of a topic or are so closely related to networking that they had been common inclusions in well-rounding training and preparation materials. These newly listed exam items are of no surprise to those already familiar with networking concepts in general or for those who have already prepared using N10-004 materials. However, one can always go for CompTIA N+ training program to speed up ones preparation and attain the certification.

There are many methodologies in which one can seek CompTIA Network+ training. With the recent technological advancements various ways has come up making IT trainings easier for us. Some of the few methods to attain this credential are:

• CompTIA N+ bootcamp training
• CompTIA N+ classroom training course
CompTIA Network+ Online trainings (Instructor led live Virtual)

Additionally, some will also see the increase in Network Security from quite few percentages (11% to 19%). It goes without saying that security has always been an integral part of Network+ since ages. In this version has simply reorganized all the previous unidentified security material under the security domain.

CompTIA certifications are usually more basic and less product specific in comparison to other IT certifications. You may take the Network certification exam, and other related IT certifications at number of testing centers around the world.
