When setting up a typical computer network, two important devices that allow for network connection are the modem and router. For those that are newer to computer networking, distinguishing between these two devices can be difficult, especially as they can either be separate or combined devices. As everyday businesses and many day to day activities now greatly depend upon functioning networks, understanding these two devices and their capabilities can be very helpful.

What is a Modem?
 
The name “modem” is a portmanteau of “modulator-demodulator”, describing the functions that a modem provides for a computer network. In simpler terms, the modem is used as a medium that either encodes or decodes information that it sends and receives from other devices. While the data is on a computer, it is stored in a digital format for use. When sending information over a network, that digital format is transformed into an analog wave and sent over phone or cable lines.
 
There are various types of modems, and these types can affect the method in which data is transferred and a network connection is established. The cable modem connects to a network via a coaxial cable that is tightened to the back of the device. The other end of the coaxial cable may be connected to a wall panel if present, or to the back of the cable box. With current technology standards, the cable modem is considered to be the fastest option with “high speed internet” capabilities. DSL is another form of modem, allowing for connection with a cable. DSL connections work through the phone line of a network infrastructure. Similar to DSL, dial-up modems also use the phone line to establish a connection to the internet service provider (ISP). Unlike DSL, however, dial-up internet connection cannot be established while a phone is being used if there is only one line. Dial-up is also the oldest form of internet connection, and it provides slower network connections as compared to the other two options.
 
What is a Router?

While modems encode and decode information for use, the router connects networks and directs traffic in between them. A network consists of the internet connection and a private local network. Devices communicate to each other over the private local network, and the router bridges the connection from the local network to the internet connection. Routers also allow for establishing a Wi-Fi network, providing an access point for wireless connection of devices to the internet. Finally, routers can provide protection to devices that connect to the internet, controlling the traffic and devices that can connect to the local network.
 
For some connections, such as a single computer on a network, a router might not be needed. Nevertheless, they are recommended for multiple devices, as well as general business and home networking. Modems and routers may be purchased as two separate devices, connecting to each other through cabling. In recent years, some ISPs have begun offering devices that combine the router and modem into a single unit. If VOIP is a need for your project, ISPs may also have router/modem combined units that also have phone interfaces.

A network adapter is defined as the component of a computer’s internal hardware that is used for communicating with another computer over a network. A network adapter enables a computer to connect with any computer, server, or other networking device via LAN connection. They can be used over both wired networks via ethernet cable and wireless networks through a router.

The network is typically the only component within a computer for interfacing or connecting with a network. Adapters are commonly built on a printed circuit board with jumpers that connect to the computer’s motherboard. Adapters for wired networks feature an RJ-45 port that uses cables for network connectivity. Wireless adapters connect to the network via a built-in or externally connected antenna. Both network adapters, whether wired or wireless, support LAN protocols like TCP/IP and others. This blog will provide further insight into network adapters, their types, and functions.

Several types of hardware adapters exist: integrated wireless chips, USB adapters, media adapter, and PCI adapters. An integrated wireless chip is a built-in network adapter that is pre-installed in a new computer. This is common only in newer models. A USB adapter is probably the most commonly-used adapter. It is a simple USB plug that fits into a port to enable computer network connections. This is found in WiFi or ethernet applications. A media adapter, sometimes called a game adapter, is used to connect to older models of game consoles or other home entertainment with modern networks, simultaneously providing WiFi capability.

The final type of network adapter, the PCI adapter, is found on older PCs. Also called a NIC(Network Interface Card), the PCI adapter is a type of add-on card installed inside a desktop computer. A variation of the PCI called a PC Card can be inserted into the side of a laptop computer and provide the same function. In addition to these, there are some types of network adapters that have no hardware component, but rather consist solely of software. These are called ‘virtual adapters’ because they lack any physical parts. Virtual adapters are commonly found in VPNs (virtual private networks), which mask your IP address and encrypt your internet traffic to protect your online identity. In addition to VPNs, virtual adapters are used in research computers or IT servers that run virtual machine technology.

How to Install A Network Adapter? 
The process of installing a network adapter differs depending on the type and model of adapter you are using, but, generally speaking, consists of two simple steps. The first step is to connect the adapter hardware to the computer, and the second is to install any corresponding software needed for the adapter to operate. Most adapters can be installed while the computer is running normally, but PCI adapters require the user to turn off and unplug the computer before installation. Regardless of the network, adapters are a necessity. Any adapter you purchase will support either WiFi or ethernet standards, and is an essential piece of both wired and wireless computer networks. Specialized adapters with very particular applications are also available, but are not commonly found or needed in most personal or workplace networks.

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.
 
Each of these parts plays an important role in the function of a computer network and communication system.

There are various benefits to acquiring a great motherboard, especially for those who enjoy or aspire to build their own PC. Along with embracing the power of deciding just how much storage your computer can hold, you can also customize the resolution for high quality graphics and more. Instead of simply buying a computer that is set with its own limitations, many people opt for building their own PC, and a significant part of this process is in choosing the right motherboard.
 
To the PC, the motherboard acts as the backbone that allows for the communication of several different components and commands. It is built as the printed circuit board (PCB) which enables the interaction between the computer’s central processing unit (CPU), graphics processing unit (GPU), computer memory, and storage. It consists of a medley of circuits, transistors, capacitors, slots, connectors, heat sinks, and more. Choosing the perfect motherboard is entirely dependent on whether or not you intend to upgrade your PC in the future. If you prefer not to have to upgrade in the future, then choosing the right motherboard now is important.
 
The first easy decision to make as you’re narrowing down to the perfect motherboard is to choose between which CPU you need for your PC. The choices are between Intel and AMD. You’ll have to do further research into these companies as both are constantly upgrading and both produce CPUs that can sufficiently meet your web browsing, productivity, and gaming needs. It’s their upgrades and features that you’ll have to look out for, as AMD’s Ryzen processors may be more suitable for apps that can use multiple processor cores at once.
 
After you’ve determined your central processing unit (CPU), the last step is selecting a motherboard that uses the correct chipset and socket. Choosing the wrong one means that you’ve just invested money into a great motherboard that simply doesn’t fit the sockets pertaining to your CPU. There are multiple places that you can reference for this, including Newegg’s online comparison tool.

Every computer needs a storage solution, somewhere that it can save and edit data for future use. (SSDs) Solid state drives and hard disk drives (HDDs) are roughly similar hard drives in their physical specifications, but store data in very different ways, and have their own sets of advantages and disadvantages.
Hard disk drives consist of one or more magnetically sensitive platters, an actuator arm with a read/write head for each platter, and a motor to spin the platters and move the arms. There is also an I/O controller and firmware that tells the HDD’s hardware what to do and communicates with the rest of the system. The platters are divided into concentric circles called tracks, which are further divided into logical units called sectors. Each track and sector number results in a unique address used to organize and locate data. Whenever a computer retrieves or updates data, the I/O controller tells the actuator arm where data is located, and the read/write head gathers said data by reading the presence or absence of an electrical charge in each address.
           
The drawbacks of HDDs are that mechanical parts used to read and write data, and physically find and retrieve the data takes more time than finding it electronically. These mechanical parts can also skip and fail if they are handled roughly or dropped. They are also heavier, and use more energy than SSDs. However, HDDS are much less expensive than SSDs, and have much more storage space.
Solid state drives are a newer type of storage device, but are progressing rapidly and adding more and more storage capacity with every passing year. Solid state drives use NAND, a type of flash memory. At the lowest level, floating gate transistors record a charge or lack of a charge to store data, and are organized into grid patterns, which are further organized into blocks. Block size can vary, but each row that makes up the grid is called a page. An SSD controller performs several functions, as well as keeping track of where data is located. Each time an SSD retrieves or updates data, the controller looks at the address of the data requested, and reads the charge status. Updating data in an SSD is more complex, as all data in a block must be refreshed whenever a portion of it is updated.
The greatest drawback of SSDs is that they are newer and therefore more expensive than HDDs. SSDs are also much smaller in terms of capacity than HDDs, which can be two and a half times larger than SSDs. SSDs however, are much faster for games, apps, and movies, are lighter and more shock-resistant, and use less electrical energy.
