Network Components
network in your new or existing location is called the name given for the system established for data sharing of more than one computer. The network, also called a network or network, is established as wired and wireless. The wired network connects computers with connections such as fiber optic cables. In the wireless network system, the devices called access points are reached by the antenna and the system works. In network installation; active and passive components.
What are the Components of a Passive Network?
The passive components used when installing the network system are;
Cabinet: cabinet is also called network cabinet. There are floor and wall types (19 inches). Inside there is ventilation with electrical outlets and consists of a metal box.
Organiser: it is the accessory that arranges the vertical and horizontal cables with the hooks inside.
Patch panel: there are 24 or 48 ports in this box, which is a kind of transfer board. The cables that provide the connection between the active device and the user can be coded here.
Patch cord: transfer cables (between the device and the transfer board) located in lengths of 1, 2, 3, 4 and 5 m that provide data communication.
Cable: it is a cable consisting of a pure glass rope and intended to transfer data for long distances in varieties that vary according to their use and categories.
Channel: they ensure the safety of cables, they are made of aluminum or metal.
Socket: equipment where the data cable and the user's device meet (it can also be mounted on the wall).
Termination box: these are the boxes where fiber optic cables are terminated.
What are the Components of an Active Network?
The active components in the network system are;
Server (server)NIC card: prepares
information to be transmitted from computers to the network environment Hub: provides a sharing path to computers (ports 8, 12, 16, 24 and 48)
Switch: is the device that filters the data from the computers and sends it only to the receiving computer Repeater: the device
that cleans and rebroadcasts the data it receives Bridge: thehardware that connects the two IPs or TCP to each other Router: Gateway: provides
access
Other Issues
In network installations, the number and size of active and passive network components can change, taking into account the need and the level of computer and security to be used.
This change is also different for wired and wireless network installations.

Firewall Solutions
The concept of FIREWALL, which is often mentioned among the issues related to security on the Internet, is the general name given to the security system that is created mainly by software, restricts / prohibits access to a system over the internet and usually works as an internet gateway service (the service that provides the main internet connection – gateway).
It is one of the various ways to protect the local network from the Fırewall internet network. In general, we can talk about two types of firewall structures; types that block data traffic and types that allow data traffic. In some firewall types, it is essential to prevent data flow, while in others it is important to regulate and limit data traffic. Often the firaws are arranged to prevent unauthorized access to the network from the outside. Access to the external network is restricted while outward access from the network is free. Some libraries only allow e-mail traffic, while others allow different types of data transmission, but block services (such as FTP, NFS, X-Windows) and some types of communication that may be problematic. Such choices and access permissions are determined entirely by the preferences of the users.
The main purpose of Fırewall is to prevent those who want to damage or infiltrate the network. In general, firewalls are a frequently used security method for companies and data centers. Firewals create a kind of gateway point for safety and supervision. In addition, when it is desired to connect to the system with a modem, Firewall has the opportunity to control and monitor this connection.
The use of various user access control and authorization mechanisms (such as a one time password) along with the firewall is also an element that increases the security of the local network. In this way, the firewall offers extra features for defining and using user passwords and authorizations and hiding the traffic of this information between networks.
Cabinet Solutions
19 Rack Cabinet or Network cabinet offers a wide range of uses for the IT and communication sector. It is needed for the security and layout of active devices with high material value in the data processing center and system rooms. It is the most suitable solution that gathers standard size 19 inch (inch) and non-standard size active devices in a single rack cabinet. Data, audio and video images can be transmitted from a single cable with structured cabling and all devices can be placed in a cabinet. Through a network system established in the Network Cabinet, all network active and passive devices can work in harmony. Equipment is safely protected.
Active and passive devices measuring 19 inches (inch) are connected directly to server cabinet or rack cabinet struts. Equipment that is not 19 inch (inch) is generally placed in fixed and movable racks of various sizes that can be mounted between 19" struts at the front and back in the rack cabinet. The hardware that can be placed in a 19 inch (inch) server or network rack cabinet can be: Server, Computer, Ups, Monitor, Keyboard, Printer, Switch, Router, Firewall, Modem, Switchboard, Patch panel and other rack cabinet accessories that allow the arrangement of passive network equipment.
What advantages do 19 inch Server or Network Rack Cabinets provide you?
Easy System Usage: Data supply and distribution points can be easily changed in the rack cabinet and malfunctions that may occur can be easily detected in advance.
Data and Information Security: The 4 doors of a rack cabinet offer the possibility to be locked with the same encrypted key if desired. Since the rack cabinet can provide this feature, it can also ensure that only authorized persons intervene in the system.
Active Device Security: Except in special cases, the rack cabinet, which is usually made of steel sheet, thus ensures the physical safety of expensive active devices placed inside. Thanks to the fan module with analog or digital thermostat mounted on the rack 19 inch cabinet ceiling, overheating of the devices is prevented and air circulation is provided in the closed cabinet.
Ease of Use and Cable Arrangement: With the regular placement of the cabinet, the space to be occupied by the devices is saved. Any future changes to the system can be easily realized by replacing the ends of the copper and fiber patch panels in the network or server cabinet. In this way, the cables get rid of the red and uneven appearance and become pleasing to the eye. The front door of the network cabinets is made of glass, the rear and side covers are made of sheet metal and are removable and lockable. In server cabinets, flat perforated or curved perforated covers are more commonly used.
