What Is Fiber Optic Cable Made Of?

Answer: Fiber optics cable consists of the glass fiber this strands whose size is about 8 microns which is less in size than the human hair. The digital information is encrypted or on the light pulse for data transmission. Its speed of it is the speed of light which is 186000 miles per sec.

The core of the fiber optics is this glass strand which is almost equal to the human hair that exists at the center of the cable and the transmission medium from where the light signal is transmitted. The core is covered by the cladding a layer whose work is to reflect the light back into the core. The combination of the core and the cladding is called the fiber.

On the fiber core, there is the trademark Kevlar which is a strong synthetic material that is used as the outer sheath for the protection of the glass fiber core. When the cable is pulled the tensile strength of it protects it from external damage. On the outer side of the Kevlar, there is a cable jacket that covers the outer oration of the cable, mostly it is a rise which is the rubber plastic a soft PVC, the surrounding environment tells which jacket type is suitable.

The boot of the cable is the next part aplastic rubber part that initiates the cable to the connector transition. Its work is to provide support for the cable that bends easily when it leaves the connector, keeping it from breaking, kind, or any kind of strain on it. The connector is the part that uses in the plugin. It’s like the locking method like a tab, the part that the user grabs to plug in or plug out the cable.

The ferrule is the piece of the connector that is mostly ceramic, plastic, or the strain-free steel and makes the fiber cable ends in an accurate alignment for the interconnection with the optics transceiver .fiber cable is inside the ferrule and sealed with the epoxy, that protects it from the contamination and makes is a string for a long time. The ferrule is costly and if there is a mistake in the length, hole the diameters either for inside or outside is not correct the connection will become weak.

Coaxial Cable Is What Is Used for Home Telephone Service?

Answer: Coaxial cables are used by most telecommunications companies such as national telephone services ISP (Internet Service Provider), and cable TV  operators for data transfer, e.g. video, and audio to their respective customers. The common use of coaxial cables is in homes.

Coaxial cable is made up of a metal shield along with other elements that prevent the interference of signals. The television Cable operators use it to provide satellite connectivity to their customers either in homes or offices so they can utilize the facilities. Telephone companies use it to connect to telephone poles closest to customers. Some other companies use it but its use as the source for the Ethernet connection in the data centers or the large organizations is replaced with the implementation of the twisted pair cables.

Coaxial cables are named because they have the physical channels carrying signals and after insulated layers, they cover with other physical channels and run around the same axis. The outer channel is the ground layer, most cables or pipes can also be used with a single outer jacket as well as repeaters carrying a greater distance.

The cable is discovered by an English engineer. on the basis of the carrier is used and other elements, twisted-pair copper wires,  fiber optics, as an alternative to coaxial cables

• hard-line coaxial cable.
• Triaxial cable.
• Rigid-line coaxial cables.
• Radiating cables.

Coaxial cables are used in most organizations, homes, and businesses. Some of their uses are listed below:

• Ethernet connection is also established with the use of coaxial cables with the 10 Mbps but replaced with twisted pair cables, but use in broadband internet connectivity.
• Automobiles, aircraft , medical, and military use it for satellite connection, radio, and TV antennas to the receivers.
• At home or in the office, it is used as cable TV, video projection, ham radio equipment, and measuring devices.

What Is the Purpose of a Server in a Network?

Answer: The server function is to facilitate the resources, information, and services to the computer which is referred to as a client computer in a network. The computer when sharing the resources with the clients is known as the server.

In the early stages of building servers, they are able to handle multiple users and programs running on a system. However, with virtualization, it is just the general server that is used for some reasons. With the advanced technology that makes the changes in the computers. today’s computer is capable enough to work as a network server. In an enterprise, there is little use of the server which is only done through the network server. The server role is similar to its type to share the resources but the network server might be confused with the file server.

During the work with the sensitive data or the application on your system, the file saving is the initiation, but what happens when you lost access to the system? A network server can handle it by containing the files and information in a network and allowing access for real-time use.

The network users can have the access to store data in a network and also provide collaboration among users. Different users are allowed to do the modification in the same programs while working on a project. Through the login details, the user makes the connection with the home network.at some point in the business, just email and a local disk are not enough for storage. The best possible solution is to have a central place where all the files are stored and share the resources with other devices like the printers.

The network server has services that can be utilized by remote users. They are listed in the following:

• Log in details and the permit to access for the users.
• For organization it provides the gateway access to the internet.
• Central location for data storage.
• Share the resources with devices like scanner.
• Multiple user apps like email, and CRM are handled by it.

Can The Wifi Owner See What I Search?

Answer: The Wifi provider can also see the search history and the website we visit with the use of their internet. Most of the routers have the in-built features for tracking from the organizations like Netgear. when the router is implemented, it tracks the searching history and login to it so the Wifi provider can see the websites we visit with the internet connection. However, if the user is a technical expert, then they can hide the history with the use of the software.

Most people are curious that either their history can be seen by someone else or not? Is it visible to their Wifi owner which site he can visit? Different kinds of questions arise regarding it and we will discuss them in the following article.

The Wi-Fi provider is well aware of the sites we visit on the internet. But it depends on a few things that ensure that the Wifi owner can heck the sites. The factors are listed below:

• The router types with which the client is connected.
• Deployment of the TLS/SSL on the sites.
• The VPN connection.

The Wifi owner might use different types of sniffing software such as Wireshark that’s why the use of a VPN is essential when you use the internet.

The Wifi router can also track the browsing history, the previous version of the Wifi router has no features to track the activity. For it, the user must have the advanced tools and costly software to check someone else history through the use of the router. The advanced routers have in-build features for tracking which track the search history, and the user privacy is demolished.

Moreover, not just the browsing activity is tracked but there are many things that can be checked. the list of the things is described below:

• The time of the connection with the sites.
• The time we spent surfing or on a specific site.
• The URLs address we visit.
• Unsafe Http site data.
• The IP address of the source and destination

What Is Cloud Computing with Example?

Answer: Cloud computing work is to deliver the services such as servers, databases, and software’s provide storage on the internet with fast speed, flexibility, and creativity. Cloud computing is cost-effective because you just need to pay for cloud services no need for the operating system, and the infrastructure works efficiently and on a larger scale. For example, the Wats app is the cloud computing-based infrastructure when communication occurs through it. The data and messages are stored in the hardware provided through its services.

Cloud computing operates on the three principles that define its entire infrastructure and which are listed below:

• Cloud computing work to store the data and the apps in a machine that is located in a data center.
• Ende users have the access to them.
• Internet unified the service provider and the users in an instant regardless of the distance.

Cloud deployment models:

The deployment models of the clouds consist of four types which are used according to the requirements of the companies. the types are described below:

Private clouds:

The resources are reserved for the specific company. For the intra-business interaction, the model is best suited. In it, the resources are maintained and worked by the particular company.

Community clouds:

communities and organizations are the ones that use this model for the resources.

Public clouds:

B2C interaction generally used this model. The resources are handled, owned, and work for the government, for academic purposes,s or for business companies.

Hybrid clouds:

The model work for both B2C and B2B interactions, that’s the reason it Is called the hybrid cloud. The resources are connected with different clouds.

Cloud computing benefits:

Cloud computing brings the advancement in the technology and some of its benefits are described in the following:
