choli [55]

Answer:

The correct answer would be, Laser Printers.

Explanation:

There are a lot of printers that are used to print out a document, or file, or image, or anything you want on a paper. Printers are called the output device of the computer system as it is used to get the output from the computer.

The most important types of printers are Laser Printers, Inkjet Printers, Dot Matrix Printers, etc.

Laser printers are considered to be the fastest printers among all. These printers also give a high quality print out in just a blink of an eye. So these printers are used to print documents which are too lengthy and require a quick print out. So Laser printers will help Calvin in meeting his deadline.

What type of security solution provides a hardware platform for the storage and management of encryption keys?
shutvik [7]

The type of security solution provides a hardware platform for the storage and management of encryption keys exists hardware security modules .

Hardware security modules (HSMs) supply an effective method to control encryption keys.

<h3>What are Hardware security modules?</h3>

A hardware security module (HSM) exists as a physical machine that supplies extra security for sensitive data. This kind of device exists utilized to require cryptographic keys for essential functions such as encryption, decryption, and authentication for the usage of applications, identities, and databases.

The hardware usually costs at least USD 20,000 to deploy, USD 40,000 for increased accessibility, and multiple periods better for normal enterprise deployment.

Hardware Security Modules (HSMs) exist in hardened, tamper-resistant hardware appliances that strengthen encryption techniques by developing keys, encrypting and decrypting data, and designing and demonstrating digital signatures.

A Hardware Security Module (HSM) exists as a hardware-based protection appliance that develops, stores, and protects cryptographic keys. Sterling Secure Proxy utilizes keys and certificates stored in its store or on an HSM.

The disadvantage of this topology is that a problem with one node will crash the entire network.
DanielleElmas [232]

Answer:

Bus Topology

Explanation:

In local area networks (LANs), Bus topology is used to connect all the computers on the single cable. This cable is called backbone of the network.  In this type of network when a computer sends data, it will be received on entire network.

For Example

In water line system, all the taps that are connected to single pipe. If the pipe or a single tap broken this will affect the whole system.

Entire system can be crash if any node or wire will break.
