Information On Networking, Cabling, Site To Site VPN And Firewalls
Information On Networking, In the field of computers. Networking is the process of linking two or even more computer devices together with the aim of sharing data between them; this is done mainly through cabling. These networking take place in form of both computer software and computer hardware. There are two general types of computer networks;
Local Area Networks
Local Area Networks (LANs) which takes the shape of geographical networking, like a network that covers a single home. This form of network utilizes cabling to transmit data between the computers. Wide Area Networks (WANs) which traverses cities, countries, continents and even the whole world. The biggest exponent of this kind of network is the Internet,
Networking can also be distinguished by design; two of the mostly known designs are; Client-server networks- that are characterized by centralized server computers whose functions include storing mail, applications, files and web to peer networks. In this kind of network all the computers in the system perform and support the same kind of functions.
Cabling is an important ingredient in computer networking as it is the medium through which data moves in a network. The usage of cables differ between networks as some use only a single type of cable while others use a catalogue of different cables. Some of the factors that affect the type of cabling include; Protocol used by the computer network, size of the network. The larger the network the larger the cable and vice versa and topology of the network area.
Site To Site VPN
Site to site VPNs help connect all networks simultaneously, one example of which is where the branch office network is connected to the central office network. Another trait of site to site VPN is that the host servers do not use VPN client software; instead they make do with VPN gateway to receive and send TCP/IP traffic. One important factor to keep in mind is to come up with a site to site VPN that is secure, applicable and affordable to use.
Firewalls are a vital component when it comes to securing your Local Area Networks to the internet. Firewalls are by definition devices or application software that acts as buffer zones between your computer network and the outside world, especially the internet. With every inconceivable activities going online, it is paramount that you ensure that your data is secure at all times. And this is where Firewalls come in. The device operates with a set of rules that determine how the computer system networks and the particular services they should use.
