Study Notes

Networking Fundamentals

In a TCP/IP encapsulation process, segments are sent from the transport layer to the internet layer.
The command show ip interface brief is used to verify the condition of the switch interfaces, including the status of the interfaces and a configured IP address.

Naming Conventions

The host names SwBranch799 and RM-3-Switch-2A4 follow the guidelines for naming conventions on Cisco IOS devices.

Powerline Networking Technology

Powerline networking technology allows a home LAN to be installed without the use of physical cabling.

VLANs

A data VLAN should not carry voice and network management traffic.

Switch Buffers

Switch buffers store frames received, thus preventing premature frame discarding when network congestion occurs.

Dark Web

The dark web is a part of the internet that can only be accessed with special software.

Python

The output of the Python expression print("%.2f"%x) where x=56.236 is 56.23.

SQL

The main difference between DELETE and TRUNCATE statements is that a delete statement enables you to selectively remove data from a table, whereas the truncate statement unconditionally removes all rows from a table.

AngularJS

The syntax module("app", []) is used to create a module in AngularJS.
Data-binding in AngularJS refers to the synchronization of data between the model and view components.

Switching

A device connecting to an existing home LAN using an adapter and an existing electrical outlet is an example of powerline networking technology.
ASIC (Application-Specific Integrated Circuit) reduces the amount of packet handling time inside the switch.

VLAN Spanning Multiple Switches

When a device in VLAN 20 sends a broadcast Ethernet frame, only devices in VLAN 20 see the frame.

Cisco 2960 Switch Configuration

The command mdix auto automatically adjusts the port to allow device connections to use either a straight-through or a crossover cable.

ARP

The property of ARP that allows hosts on a LAN to send traffic to remote networks is that local hosts learn the MAC address of the default gateway.

Java

The extension of compiled java classes is .class.
The output of the given Java code is 1.

React.js

A state in React.js is also known as internal storage of the component.
The correct way to access the state of a component from inside of a member function in React is this.state.

REST API

The component used for specifying the protocol used for transmitting the request in a REST program is the URI scheme.
The default media type for requests and responses in a REST API is application/json.
