Answer:
Nancy's private key
Explanation:
She's receiving it. That means Matthew used her public key to encrypt it. She should decrypt it using her private key. Watch this video for clarification :)
Watch The Internet: Encryption & Public Keys on the big video site which cannot be named on brainly :p
When somebody writes the answer for your question and posts it on your question it will show a “(crown)mark as brainliest” in blue. click it and it’ll turn yellow and mark the person the brainliest for your question
The advantage does of ExpressCard modules and U.S.B adapters offer over expansion cards is that it can connect a variety of devices to a computer. The technical standard of ExpressCard specifies the design of slots built into the computer and of expansion of cards to insert in the slots including the mobile broadband modems. It is sometimes connectors for externals devices such as flash drives, USB connectors and other ports that need to connect to the computer.
Answer:
True
Explanation:
Computer security is basically divided into three main areas:
- Vulnerability/threat assessment and risk management refers to a process that requires the identification, quantification and ranking of a system's possible vulnerabilities.
- network intrusion detection and incident response refers to software that detects malicious activity or policy violations, and blocks them
- digital forensic investigation refers to the process of identifying, recovering and interpreting (or validating) electronic data.
Generally a single individual may specialize in one of these areas, that is why he/she may need help with the others.
Answer:
Switches break up collision domains and routers break up broadcast domains.
Explanation:
- Collision domain depicts the part within a network where a collision can happen.
- Collision occurs when two hosts transmit data packet at the same time within a network. Theses packets collide and the hosts have to resend the data after some time.
- Too many collisions can result in slow traffic speed and can effect network performance.
- So switches break up collision domains between the devices on a network and each port in a switch depicts a collision domain. This reduces the chance of packet collisions between the devices or hosts.
- When data is to be sent to a host, the switch keeps that data frame and waits for availability of the destination host before sending the data frame.
- Moreover full duplex switch mode there is not chance of collision as the transmitting path on one host is the receiving path on other host.
- Broadcast domain contains all the hosts that can reach each other at the Data Link layer via broadcast.
- Routers break up broadcast domains as routers contain separate broadcast domains for each interface.
- Routers do not forward broadcasts from one broadcast domain to other and drop the packet when they detect a broadcast address.
