Computer Networking: Elements And Components

The message is generated by the end user that needs to make the transmission. This message will be fed to the network later. Medium: the medium is the transmission path over which the data will be transmitted. Is is used to connect the end user with the network device or to connect the network devices with each other. Many types exist for the medium. Mainly it can be wired or wireless medium. The wired medium can be copper or optical fibers. The copper is subdivided into coaxial cables and twisted pairs. The copper wires carry data as electrical pulses while the optical fiber carry data as light pulses. The wireless medium carries data as electromagnetic waves. Each of the above mediums has its own specifications and used according to the application.

there are two basic types of devices in the network: end user devices and network devices. The end user device is considered to be the source of the message. It can be a client computer or an IP phone. The function of the end user device is to send the data to the network. The main function of the computer network devices is to forward the data to the correct destination based on the address that is send along with the data. The two main devices that accomplish this are the routers and the switches. The router forwards the data according to the IP address while the switch forwards the data according to the MAC address inside the data frame.

Do Customers Care About Microsoft Certification?

I Work for a London based IT Support Company and have done so for the last several years, during this time my company has spent literally thousands of pounds ensuring all the staff get the latest qualifications so we can be a ”certified partner” of various IT related industries. And what do the customers think? Well I can tell you from speaking with our sales staff that 75% of potential clients couldn’t care less when it comes to certification. The old one liner of “we are Microsoft Gold Certified” just doesn’t cut it in this day and age with clients, their perspective on things is that all IT support companies are capable of doing the same job; they just want the cheapest one.

Getting qualifications from companies such as Microsoft isn’t cheap; we pay a pretty penny to be Microsoft gold certified. But don’t get me wrong, being certified does have its benefits’ internally as we get access to resources that wouldn’t normally be available and we get discounts on software etc etc. At the end of the day I will keep our engineers qualified as it feel it reflects well on us as a company. Although I have full confidence in my engineers, getting them to sit exams does keep them on their toes and that can only benefit everyone.
