Computer Networking

Because networking is a relatively young science, it borrows language from other disciplines. Many networking terms come from the realm of physical transportation–terms such as bridge, hub, port, routing, and switching. That borrowing is apt. Just as the transportation revolution, and especially the advent of the railroad, was an economic catalyst of the Industrial Age, networks are the economic catalysts of the information age. And just as railroads need a solid infrastructure, so do networks. The foundation technologies of networks are routing and switching.

The Basics

In its most basic form, a network consists of two pieces of electronic equipment that communicate data back and forth, connected by a third piece of equipment that enables that communication. A printer attached directly to a computer via a parallel or USB cable does not comprise a network; it becomes a network if the printer and computer are both attached to a switch or router. The Internet provided the impetus for most companies to adopt a network infrastructure. Even the smallest businesses need network-enabled Internet connections to send and receive e-mail, advertise and sell products and services online, interact with customers, and connect with suppliers. Moving to a networked environment opens new possibilities, including online business applications and collaboration opportunities. Data security also becomes a central consideration with a network. While switches and routers have evolved and the lines between them may seem blurred, one simple distinction remains: Switches reside within a local-area network (LAN), while routers are needed in a wide-area network (WAN) environment. It’s analogous to an old-fashioned office phone: Switching is like dialing a four digit extension to reach someone in your building, while routing is like dialing 9 to get an outside line, and then dialing a seven- or ten-digit phone number.

IT Networks though simple, require extensive planning to ensure stability, yet we often encounter businesses that are unacquainted with the imperative role networking plays in the efficient functioning of their company.

Informed business entrepreneurs often opt to upgrade their networking systems to suit their organizational structure. Although upgrading is an expensive, time consuming process, its benefits are ten fold. Though, there are some small size companies that insist on having a Windows XP workstation function as a network server, this decision may eventually lead to decrease in efficiency and productivity of the entire Information Technology environment.

Network Consultants should always analyze the nature of your business so as to recommend a networking/Information Technology system that would be the best fit for your business. IT Consultants should evaluate both hardware and software requirements to guide your company through the pros and cons of various networking options that your business may be considering.

From a network consulting standpoint, these are five common problems that are either neglected by businesses or not included in the overall planning of the Network Infrastructure.

Disaster Recovery: Although entrepreneurs are risk takers they provide for all contingencies. While they insure their store and goods against fire, theft, natural calamities, etc., in many cases they ignore the need to implement a disaster recovery plan for financial records, employee payroll and client data. Losing valuable customer information to a fire would result in temporary chaos and a financial drain. Therefore, a data recovery system should be available to restore normal operation within 24 to 48 hours.
There are several options to evaluate depending on the size of the business. A good Technology consulting company should be able to assess the needs and accordingly recommend an IT recovery plan that is fool proof yet affordable. Read the rest of this entry »
