A computer network is a good example of something being greater than the sum of its parts. The combination of servers, workstations, network interface cards, active & passive hubs, routers, bridges, and much more create a network of operating parts that put the world at a user’s fingertips. Each of these parts has an important task in the function of the computer network. This blog will explain what a computer networking system is and many of the smaller parts it consists of.
 
Servers and clients are the two components making an exchange within the network. A server, the most powerful component of a network, is a computer that holds shared files, programs, and the network operating system. Servers provide access to resources to any user of a given network. Servers come in varying types and configurations, and a single server can provide multiple services. Servers are sometimes referred to as host computers. A client in this case is a computer that accesses the server, network, and shared network resources. Client computers are essentially the user of the network. For example, if you are playing an online video game, your gaming console is the client of the game’s network. Clients are also sometimes referred to as workstations. To function, a client must be equipped with the hardware and software necessary to connect to a LAN (local area network) whether it be wireless internet or a wired connection.
 
The servers, clients, and network as a whole are controlled by the network operating systems (NOS). The NOS is the component that controls communications and shared resources on the network, as well as provides distributing processing ability. Current NOSs provide the basis for client/server applications, integration of all types of computers, and connection of workgroups. The operating system works in tandem with the computer’s operating system. Each client needs an additional card known as a network interface card (NIC). The NIC’s job is to move signals from from the network to the data stream inside the PC via network cables. It can also format data and control the flow of data from the client to the network and vice versa.
 
The heart of any network is called the hub. The hub is a centralized distribution point for all data transmission in a network. The hub receives transmissions and rebroadcasts them to the other clients connected to the network. In most cases, the hub is a passive device, meaning it does not know the destination of the data it receives and instead sends copies to all connections. Similar to the hub, the switch is a telecommunication device like a hub but with more advanced features. Switches use physical device addresses in incoming messages to identify the right destination or port to which the message must be delivered.
 
The router is a networking device that forwards data packets between computer networks. Routers direct information sent through the internet, such as a web page or email, from one router to another until the data reaches its destination. They are connected to two or more data lines sourced from IP networks. When data comes in, the router reads the network address to determine the final destination before directing the data to the next network.

Having a few media converters in your toolbox can increase your flexibility while decreasing stress on the job. In this article, we will be covering the basis of media converters and their most popular uses.
               
Now, what is a media converter? It essentially acts as the glue for networks. It helps connect networks made up of different signal types, network protocols, data rates, connectors, or cabling types through on transceiver. A media converter is versatile because it converts light waves into electrical waves and electrical waves into light waves. Some types include copper to fiber, coax to fiber, fiber to fiber, and single mode to multi-mode.
 
There are a few factors that make media converters the superior and smarter choice to use. Older equipment, or legacy equipment, is the cheaper and easier solution to a new computer. The same thought goes into older buildings or complexes, or legacy buildings, where the rewiring of a whole structure is just not feasible or practical. These situations are ideal to utilize a media converter to drive costs down and productivity up. Cutting down on cost has made the media converter steadily more popular over the years.
 
 With the ever-changing technology of our world, the need for media converters increases. Fibers that are located outside, WANs and LANS, remote management with monitoring capabilities, and enhanced bandwidth that allows signals to go in 2 directions are a few reasons why these devices are selling in mass quantities recently.
 
There are several types of converters that can meet any need. There are a few questions you need to ask yourself before purchasing. Firstly, ask yourself what kind of network it will need to support? What cable or connector type do you use? What type of cables are you connecting? Finally, you need to ask yourself what kind of tasks you will need the media converter for, managed or unmanaged capabilities?
 
Here are some recommendations for media converters depending on how you answered the questions above. Ethernet converters connect different types of network media to allow them to connect, no matter their individual data rates. Some models can rate switch anywhere from 10/100 to 10/100/1000. A fiber media converter can switch between multi and single mode. The two types, optical and coaxial, transmit signals in either a form of light or a form of electricity, respectively.
 
The main goal of media converters is to decrease the amount of money spent to keep ethernet strong and increase the speed of all devices to run an overall smoother business in any setting.

A network switch is a computer networking device that keeps users connected to each other and to the internet. It’s not just the computer itself that benefit from this device: printers, gaming consoles, DVD drives, etc. benefit from this as well. It allows you to perform various functions on multiple devices. Choosing the network switch that is right for you depends upon factors such as the number of devices and the number of people that are going to be using the network. Some of the different types of network switches are local area network (LAN) switch or active hub, unmanaged network switches, managed switches, and routers.
 
The LAN switch or active hub is also known as the local area network or Ethernet switch. It connects points on a company’s internal LAN and allocates the bandwidth economically so overlapping data is blocked. The LAN switch delivers data to its intended recipient and reduces traffic.
 
Unmanaged network switches are the easiest to install and are used mostly in home or small business settings. They also allow different devices to connect with each other. Managed switches can be customized and can enhance a networks functionality. There are two types of managed switches: smart and enterprise. Smart switches have limited features but create a web interface and accept configurations of basic settings. Enterprise switches have a wide range of management features and are often found in large companies that have a lot of connections, nodes, switches, and ports. Because they are more customizable, they are more expensive. Routers send data along networks and are usually connected to LANs or wide area networks (WANs). They are able to connect more than two networks.

A Digital Subscriber Line (DSL) uses the same wires as a telephone line to generate high-speed internet connection. The wires used in telephone installation can handle a greater range of frequencies than those used for voice. DSL takes advantage of this without having to disturb the line’s ability to carry a conversation.

ADSL, or asymmetric DSL, works on the assumption that users browse more information than they send. ADSL is sensitive to distance, limited to 18,000 feet. The maximum downstream speed is 8 megabits/second and maximum upstream speed is 640 kilobits/second. ADSL can be disqualified when loading coils, which boost voice signals, are used. Bridge taps, fiber-optic cables, and distance can also compromise ADSL signals.

Two standards for ADSL are the discrete multitone system (DMT) and the carrier less amplitude/phases system (CAP). DMT divides data signals into 247 channels, each 4 KHz wide. The system switches between channels to find the optimum for transmission and reception. CAP divides signals into three bands. Voices are carried in the 0 to 4 KHz band, the upstream channel is carried between 25 to 160 KHz, and the downstream channel is carried between 240 KHz and 1.5 MHz. Low-pass filters are used to block signals above 4 KHz. These prevent data signals from interfering with phone calls.
The DSLAM, DSL access multiplexer, consolidates connections from many users onto a single connection to the internet. DSLAM supports multiple types of DSL in a central office and different varieties of protocol and modulation in the same type of DSL. ADSL connections trace back to the DSLAM which prevents performance decrease as users increase.

Other types of DSL include: very high-bit rate DSL (VDSL), symmetric DSL (SDSL), rate-adaptive DSL (RADSL), ISDN DSL (IDSL), and universal DSL (Uni-DSL). DSL alternatives include cable and wireless.
