What Protocol Below Supports Two Encryption Modes: Transport And Tunnel?
The IPsec protocol supports the two encryption modes called the transport mode and the tunnel mode. Today let us discuss the Ip security protocol and its two encryption modes.
Typically, the security protocol will be applicable on the three layers. They are the Application layer, network layer, and transport layer of the OSI model. When we apply the security on the network layer of the OSI model, then we call it the Ip security protocol. Now, let us discuss the IPsec protocol in detail. As we discussed earlier, the IPsec protocol has two encryption modes. They are Transport mode and the other one is tunnel mode.
The network layer security can be between any two hosts, any two routers or it can be between a host and the router. The main aim to design the IPsec protocol is to provide security at the network layer of the OSI model. Now, let us discuss each of the layers in detail. The transport mode can be defined as protecting or give security to the data which is delivered from the network layer to the transport layer of the OSI model.
The data that is sent to the transport layer will be protected by the IPsec.
Here we have to remember that the transport mode, will only protect the data that is coming from the transport layer. It doesn’t protect the Ip header, but only protects the packet that is coming from the transport layer of the OSI model.
Another encryption mode is called the tunnel mode, here the tunnel mode will protect the entire Internet protocol data packet that is coming from the transport layer. The Ip security protocol will be applied to the whole IP packet. It is applied between the host to host or between a router to router or it can be between a host to host.
Tunnel mode is an operation mode of the IPsec. Let us take an example to understand this tunnel mode in detail. Let say we have two hosts that are between the two different local area networks. There is a gateway present between the two local area networks. Here, the traffic that is coming from host A to host B will automatically be protected by the tunnel. Host A can send packets that are not protected or encrypted by the hosts. The gateway that is present between the local area networks adds the protection and then it sends the packet to network B. And at host B, it will decrypt the packets that are sent by host A.
A protective packet will be delivered between the B’s gateway.
The main difference between the tunnel mode and the transport mode is that the tunnel mode can able to protect the entire packet and the transport mode will only protect the packet that is coming from the transport layer of the OSI model. This process can be done between the host to host or router to router or can from any node to node.

What Kind Of Cable Uses Bnc Connectors? Which Connector Is Likely To Be Used By Cable Tv?
The coaxial cable is used BNC connectors. The F-connectors are likely to be used by the Cable TVs.Today let us discuss the coaxial cable and the F-connectors. We use many different types of cables to connect to the different devices. Typically, the common cables we use in the networking are coaxial cables, optical fiber cables, twisted pair cables, and parallel and serial cables. These cable’s usage depends on their network size hardware and the software cables.
All these network cables and their connectors depend on the physical layer of the OSI model. The physical layer is layer one of the OSI model. Today let us discuss some of the common connectors along with the coaxial cables. The below figure 1.1 represents the structure of the coaxial cable. The outer cover of the coaxial cable is called the sheath. The braided metal sheath is used to reduce interference. This interference is called electromagnetic interference.
The underneath of the shielding is also called the Teflon insulator. The copper conductor is present at the central metalcore. let us know some of the uses the coaxial cables are mainly used to carry a high frequency of the electrical signals with the minimum number of the losses. These coaxial cables are normally used in telephonic systems, and in the cable TVs, ethernet, and also in the broadband ethernet.
We have many specifications in the coaxial cable, but the coaxial cable only uses the RG number in it. But what is the RG number?. The name RG stands for radio guide. Each of these types is used for different purposes.
We have an RG-6 coaxial cable, mostly used for home purposes. If we have a cable TV or a Cable connection, these RG-6 coaxial cables are used. We measure the coaxial cables in the terms of Ohm for their resistance. The Ohm is used to measure the electrical current that is passing through a circuit. The difference in the coaxial cable cannot be identified by their physical appearance.
In the coaxial cable, we have common connectors like F-type connectors, SMA connectors, N connectors, and BNC connectors. Now, let us discuss the F type of the connectors in detail. These F types of connectors are normally used to connect the cable TVs. We use this to connect to a cable modem if we have a cable internet connection. The F type of the cables is got terminated through the RG-6 cables.
When we compare coaxial cables with the twisted pair cables, the coaxial cables will carry signals to a much farther distance than the twisted pair cables. But the twisted pair cables have a higher transmission rate when we compared them with the coaxial cables.
The BNC connectors stand for British Naval Connectors. We also have the N connectors which are the whether-proof connectors. The N connectors will carry the microwave signals, and at last, we have the SMA connectors, the SMA connectors are mainly used by the high-frequency microwave systems.

What Is The Minimum Category Of Utp Cable Required In Order To Support Gigabit Speeds?
The CAT5 cable is the minimum category of the UTP cable required in order to support gigabit speeds. Today, let us discuss the cables in detail that support the speed of the gigabit. There are several different types which we can choose from, we have Cat5, Cat 5e, Cat 6, and Cat 6a cables in it. The Cat stands for category and 5, 5e, 6a are the many different standards of it. All this will use the RJ45 connector known as the ethernet ports. let us learn all the different types of ethernet cables in detail.
The first really common category is cat5, here we also have the new version of the cat 5, the Cat 5 cable can only be rated up to 100Mbps. That means it can only be rated up to 100 meters with a bandwidth of 100 megabits per second. So this Cat 5 cable cannot be seen since it only moves up to 100Mbps.
And we have Cat 5e which is an enhancement of Cat 5. The Cat 5e is the most common cable and it can be rated up to one-gigabit speeds for a distance up to 100 meters. And it can have a bandwidth of 100 Mhz. The Cat5 cables only require two twisted-pair cables and Cat 5e uses four twisted-pair cables. Hence the Cat 5e can able to transfer more data than Cat 5.
We also have the Cat 6 which will speed up to 1 gigabit to 10 gigabits per second at a distance of 55 meters in length and with a bandwidth up to 250Mhz. The bandwidth is nothing but the range of frequencies where a cable is able to use reliably and will also explain how would improve the speed.
We have the Cat 6a cables, which are also capable of 10 gigabits and with a longer distance of 100 meters and with a larger bandwidth of 500Mhz bandwidth. The Cat 6a will be more reliable for getting at a full speed of 10 gig network. It also has an improved specification for reducing the cross talk.
And the larger of all the ethernet cables are the Cat 7 cables. The Cat 7 cables are the fastest cables that we can buy at the moment in the markets. The Cat 7 cables also are rated as 10 gigabits speed with a larger bandwidth up to 600Mhz. The Cat 7 cables have some of the strict specifications for reducing the crosstalk. It provides a separate shield between the individual pairs. This is mainly for improving reliability. This cable is most suitable for permanent wire installations.
All these cables work with the minimum gigabit speed of 10. As we discussed earlier, all these cables will be connected to the Rj45 connector. All these different numbers will represent different versions that are present in the Cat cables. All these can work with the minimum of gigabits speed. But the main difference is rated through their performance.
