How is data transmitted securely over a network?
Data is transmitted securely over a network through encryption, which scrambles the data into a code that can only be read by authorized parties with the correct decryption key. This ensures that even if the data is intercepted, it cannot be understood by unauthorized users. Other security measures, such as firewalls and secure protocols, also help protect data during transmission.
How do you describe a modem in layman's terms?
A modem is a device that connects your home network to the internet. It takes the digital information from your computer and converts it to a format that can be transmitted over a telephone or cable line. The modem at the other end receives this information and converts it back so that your computer can understand it.
The speed of the net access is defined as the?
The speed of net access is typically defined as the rate at which data packets can be transferred between a device and a network. It is measured in bits per second (bps), with common units including Mbps (megabits per second) and Gbps (gigabits per second). The higher the speed, the faster data can be transmitted and received over the network.
How does the g s m work?
GSM (Global System for Mobile communication) works by digitizing and compressing voice data, which is then transmitted as a digital signal over radio waves. These radio waves are received by nearby cell towers, which then route the signal to the intended recipient via a network of switches. This system allows for mobile phones to communicate with each other regardless of their location, as long as they are within range of a cellular network.
What is conjection control?
Congestion control refers to techniques used in computer networks to manage the flow of data traffic in order to prevent network congestion. It helps to ensure that the network operates efficiently by regulating the rate at which data is transmitted and making adjustments as needed to avoid overwhelming network resources.
Which of the following is something a network adapter does NOT do?
it verifies that all information transmitted from the computer is correctly received by the recipient.
How do magnetic strips on credit cards work to store and transmit payment information securely?
Magnetic strips on credit cards store payment information using magnetic fields. When swiped, the information is transmitted to a card reader, which then verifies the transaction securely through a payment network.

What information can be gathered by using the command netstat?
The command netstat provides information about network connections, routing tables, interface statistics, masquerade connections, and multicast memberships. It can show all active network connections, listening ports, and the state of the connections. Additionally, it displays information about routing tables, interface statistics such as packets transmitted and received, and network protocol information.
What is the unit of information called when a network adapter adds the source and destination MAC address to the segment of data before it is transmitted on the network?
Packet
What is insertion loss in network analysis?
The Insertion Loss of a line is the ratio of the power received at the end of the line to the power transmitted into the line.
Information can be transmitted via of which siganlling methods?
Depends what sort of signalling - SS7 is used in telecomms networks. Different flavours in different networks and customer to network interface is different to network to network
What is inranet and how does it work?
An intranet is a private network that uses internet protocols, network connectivity, and public telecommunication system to securely share part of an organization's information or operations with its employees.
Does copyrights and patents protect personal information being transmitted over a network?
No; privacy law would be more involved with this.
What is the differnece in how voice is transmitted over a PSTN and how voice is transmitted over an IP network?
The difference: With PSTN, the voice is transmitted through the network of cables. While with VoIP is transmitted through the internet. This is the main difference between the two communication systems.
The 2 security methods used on network?
There are two types of network security concerns: network infrastructure security and content security. Securing a network infrastructure includes the physical securing of devices that provide network connectivity and preventing unauthorized access to the management software that resides on them. Content security refers to protecting the information contained within the packets being transmitted over the network and the information stored on network attached devices.
What is a network that transfers private information securely over the Internet of other public network?
That is called a VPN - Virtual Private Network. The basic idea is that information is encrypted before it is sent over the public network.That is called a VPN - Virtual Private Network.
