Internet Gateway Advantages And Disadvantages

1)A network is when two or more computers are connected together and are able to share data and communication.

A: LAN: LAN stands for Local Area Network. LAN is a network which cover a small area like colleges, schools or buildings.

Firewall: A firewall is a software or hardware-based network security system that controls the incoming and outgoing network traffic by analysing the data packets and

Measures for information transmission on fiber optic lines-can stretch out in reach up to 124 miles.

A LAN is a ‘Local Area Network’. It is a small network of computers most often

Bridge is a simple device that aids in interconnecting similar LAN's between local area networks that use identical protocols for the physical and data link layers in accordance with the IEEE 802.3 standards. As the devices connected to the bridge use the same protocols, the amount of processing required is minimal. Nowadays, routers are used more commonly to interconnect LAN’s as bridges are Layer 2 devices and pose almost no security while the router is a Layer 3 device and offers better Data Security.

A Router is a Layer 3 or Network layer device that connects a network to another network. It connects networks with the same protocol such as RIP (Routing Information Protocol) and IP (Internet Protocol).

This created physical connection between PC’s and the network line. Connected data’s are transporting data’s through the network. Cable is a medium through which information usually moves to one network to another network.

When a computer needs to send a packet to another subnet, it sends the packet to its default gateway, which is also known as the default router.

A network is the way to communicating throughout the internet; also, it is connected to the group of computers that allow to sharing the information through a network. Not only that network is just for sharing the information though connected of group computers, but for internet that including social media, game online, telecommunication, programming that would be require network for professional career, and more that can be any in the real world, even that can be also for security throughout network to protect whoever uses network for personal and business. A network is a-must

A firewall is a system or group of systems that enforces an access control policy between two or more networks. The means by which this control is accomplished varies widely, but in principle, the firewall is a pair of mechanisms, one that blocks traffic and one that permits traffic. Some firewalls emphasize blocking traffic, while others emphasize permitting traffic. The most important thing to recognize about a firewall is that it implements an access control policy. If you don't know what kind of access you want to permit or deny, or you let someone else or some product configure a firewall based on judgment other than yours, that entity is making policy for your whole organization.

A LAN is a network of computers in a specific area interconnect using a variety of network media. For example, WBHS LAN are all the computers connected to the WBHS network via Ethernet, Wi-fi or other. This is different from a WAN (Wide area network) which extends to a much wider area such as a town, city and country. LAN are usually more restricted in access and more numerous.

This is one of the crucial advantages of networking computers. Everyibe can find and share data because of networking. This is beneficial for large organizations to maintain their information in an

Advancements in the information technology sector have brought many benefits to the people all around the world.  Today with computer networking, we can chat, speak and see each other over a long distance. Data communication refers to the transmission of the digital signals over a communication channel between the transmitter and receiver computers. Communication is possible only with wired and wireless connectivity of the computers with each other.
