Study Notes
Network Characteristics and Security
- A violation occurs when network confidentiality is compromised, allowing patients to access each other's medical records.
- Minimum security for a small office network includes implementing a firewall and establishing strong password policies.
Network Medium Selection
- Selection criteria for network media include bandwidth capacity and distance between devices, influencing performance and range.
Quality of Service (QoS)
- QoS is essential for managing traffic types that require timely delivery, such as voice and video calls, to ensure quality service.
Cisco IOS Management
- Password protection can be applied to various interfaces in Cisco IOS, including console and VTY interfaces.
- The management interface for a Layer 2 switch typically uses the VLAN interface for remote access.
Command Functions in Cisco IOS
- Pressing the Tab key during command entry in IOS auto-completes commands or options, enhancing efficiency.
- The command
service password-encryptionencrypts all unencrypted passwords in the configuration file to enhance security.
Network Traffic Management
- Flow control techniques help two computers manage packet transmission efficiently to prevent data loss during high traffic.
TCP/IP Encapsulation Process
- In the TCP/IP encapsulation process, a source IP address is added at the network layer, while the destination port number is added at the transport layer.
TCP/IP Protocol Suite
- Three key application layer protocols in the TCP/IP suite are HTTP, FTP, and SMTP, enabling web browsing, file transfer, and email communication.
IPv4 Configuration
- The network and host portions of the IPv4 address are identified by the subnet mask during manual configuration on devices such as web servers.
Computer Threats
- A spyware threat is characterized by a program that secretly collects data about visited websites of an infected computer.
Network Types and Trends
- A Virtual Private Network (VPN) provides secure access to corporate offices for suppliers, customers, and collaborators.
- The trend allowing users to access company resources from personal devices is known as Bring Your Own Device (BYOD).
Networking Terminologies
- ISP stands for Internet Service Provider, which delivers internet connectivity to users.
- Employees retrieving confidential information within a corporate network would access an intranet.
Powerline and Wireless Networking
- Powerline networking utilizes electrical infrastructure to transmit internet data, allowing connectivity through outlets.
- Networking technicians working on wireless networks at medical clinics focus on ensuring secure and reliable wireless communications.
Network Models and Policies
- A peer-to-peer network allows computers to function as both clients and servers.
- Telecommuting involves using a home or small office network for remote work.
- Server virtualization refers to a model where server applications run on dedicated hardware.
- Quality of Service policies prioritize voice and video traffic within data flow management.
- An organization's network that comprises a private collection of LANs and WANs is termed an enterprise network.
- Device compatibility across business networks is known as cross-device functionality.
OSI Model and Packet Encapsulation
- A source IP address is added at OSI Layer 3 during the encapsulation process.
- A destination port number is incorporated at OSI Layer 4, ensuring the correct application receives the data.
