What guided media is most favored, and why?
Fiber optic cables can transmit data over far greater distances than copper cables can, thanks to their use of optical fiber. Fiber optic cable is more trustworthy than copper cable because it is resistant to any temperature fluctuations, whereas temperature variations might produce an obstruction in the connectivity of copper wire. This makes fiber optic cable more reliable than copper cable.
Which transmission media are guided and unguided?
Guided In guided media, the data being sent makes its way through a cable system that follows a predetermined course. For instance, copper wires, wires made of fiber optics, and so on. Unguided In unguided media, the data that is being communicated takes the form of an electromagnetic signal and travels through empty space. Radio waves, lasers, and other similar technologies are examples.
Which transmission method has the lowest latency or delay for moving large amounts of data over long distances?
Optical fiber can transport massive amounts of data across great distances with very little delay or latency. Optical fibers are produced by employing the process of reflecting light through a core that is composed of either glass or plastic. This allows the light to be guided in a certain direction.
Which kind of network is most likely to be restricted to a single structure or campus?
A network that is restricted to a comparatively localized region is referred to as a local area network (LAN). In most cases, it is restricted to a certain geographical location, such as a school, building, or writing lab.
In what ways is data transmission secure?
In the field of computer science, the term “secure transmission” refers to the process of transmitting data such as sensitive or proprietary information through an encrypted connection. Encryption is necessary for many different types of secure communication systems. PKI stands for public key infrastructure and is the most widely used method for encrypting email. An exchange of keys is required before the encrypted file can be accessed and opened.
Which of these methods of data transfer is the safest: HTTP or HTTPS?
HTTPS adds encryption to the HTTP protocol. The standard HTTP requests and answers are encrypted with TLS (SSL) when using HTTPS rather than HTTP. This is the primary distinction between the two protocols. Because of this, HTTPS is a far more secure protocol than HTTP. The prefix “http://” is used in the URL of a website that utilizes the HTTP protocol, whereas the HTTPS:// prefix is used for a website that uses the HTTPS protocol.
Why are infrared transmissions becoming more common?
The inability of infrared light to pass through solid objects is one of its defining characteristics. This indicates that it is possible to include it into a room in a straightforward manner. Another advantage of infrared communication is that it has a vast bandwidth that can be used, although it has not been utilized to its full potential yet.

The concept of network security is extremely all-encompassing, including a wide variety of technology, equipment, and operational procedures. It is a collection of rules and settings meant to safeguard the integrity, confidentiality, and accessibility of computer networks and data by utilizing both software and hardware technologies. Put another way, it is the most basic definition of what information security is.
What makes WPA insecure?
WPA is the option to go with since it uses an encryption mechanism that is not as robust and requires a password that is shorter. WPA is not designed to have a level of security that is sufficient to allow its use in a corporate setting, which is why there is no enterprise solution for it.
Among them, which has the best wireless security?
Who of them offers the most reliable protection for your cellular data? Explanation: Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), Wi-Fi Protected Access 2 (WPA2), and Wi-Fi Protected Access 3 (WPA3) are the most comprehensive forms of wireless security. WPA3 is the most secure and up-to-date encryption standard. 3.
What distinguishes baseband transmission from bandpass transmission?
The signal is sent without being modulated during baseband transmission, which is ideal for communications over shorter distances. When communicating over long distances, bandpass transmission is necessary because the modulated signal needs to be moved from baseband frequency to a higher frequency. This shift is accomplished by bandpass transmission.
Broadband or baseband DSL?
The most apparent applications of broadband technology are high-speed Internet connections that are provided to private residences via newly installed cable television systems (cable modems) or by digital subscriber loops (DSL).
What three different ways can data be transmitted?
The communication mode or mode of transmission of data can be of three types.
