What does STP standard temperature and pressure stand for?
What does STP standard temperature and pressure stand for?
Standard temperature and pressure, abbreviated STP, refers to nominal conditions in the atmosphere at sea level. Standard temperature is defined as zero degrees Celsius (0 0C), which translates to 32 degrees Fahrenheit (32 0F) or 273.15 degrees kelvin (273.15 0K).
What is standard temperature and pressure in Kelvin and ATM?
Standard Temperature and Pressure. Standard temperature is equal to 0 °C, which is 273.15 K. Standard Pressure is 1 Atm, 101.3kPa or 760 mmHg or torr. STP is the “standard” conditions often used for measuring gas density and volume.
What are the conditions of standard temperature and pressure STP for a gas?
Since 1982, STP is defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of exactly 105 Pa (100 kPa, 1 bar).
What is the temperature give in both C and K at STP?
Both STP and standard state conditions are commonly used for scientific calculations. STP stands for Standard Temperature and Pressure. It is defined to be 273 K (0 degrees Celsius) and 1 atm pressure (or 105 Pa).
Which one is the first step in STP operation?
When you enable STP, the first step in its convergence process is to elect a switch to act as a root bridge using the Spanning Tree Algorithm. To accomplish this, all network switches participation in STP exchange BPDU frames to determine which one has the lowest bridge ID (BID).
What is STP convergence?
Spanning Tree Protocol (STP) convergence (Layer 2 convergence) happens when bridges and switches have transitioned to either the forwarding or blocking state. When layer 2 is converged, Root Switch is elected and Root Ports, Designated Ports and Non-Designated ports in all switches are selected.
How does STP protocol work?
Spanning Tree Protocol (STP) is a link management protocol that provides path redundancy while preventing undesirable loops in the network. When it comes to ethernet networks, only one active path can exist between two stations in order for them to function properly. Loops occur in networks for a variety of reasons.
How does STP decide which port to block?
Each switch uses the STA to determine which ports to block. While the STA determines the best paths to the root bridge for all switch ports in the broadcast domain, traffic is prevented from being forwarded through the network.
What port is STP?
Spanning Tree Protocol, Rapid STP Port Costs – Port States
| STP (802.1D) Port State | RSTP (802.1w) Port State | Is Port Included in Active Topology? |
|---|---|---|
| Blocking | Discarding | No |
| Listening | Discarding | Yes |
| Learning | Learning | Yes |
| Forwarding | Forwarding | Yes |
What is an advantage of Pvst +?
What is an advantage of PVST+? PVST+ requires fewer CPU cycles for all the switches in the network. PVST+ reduces bandwidth consumption compared to traditional implementations of STP that use CST. PVST+ optimizes performance on the network through autoselection of the root bridge.
Which state of the default STP configuration allows ports to listen for BPDUs but not send any?
A port in the blocking state does not participate in frame forwarding and also discards frames received from the attached network segment. During blocking state, the port is only listening to and processing BPDUs on its interfaces.
Which command will enable port security?
Use the switchport port-security command to enable port-security. I have configured port-security so only one MAC address is allowed. Once the switch sees another MAC address on the interface it will be in violation and something will happen.
What is the status of designated port?
The Designated Port is the port that has the lowest Path Cost on a particular Local Area Network (LAN) segment. Each segment has a single port that is used to reach the Root Bridge (Root Switch) called Designated Port. A Root Port can never be a Designated port.
Which two issues are the result of a broadcast storm?
Which two issues are the result of a broadcast storm? Due to high processing demands during a broadcast storm , communication may fail between end stations in the broadcast domain. Durining a boardcast storm , constant changes to the MAC address table prevent a switch from accurately forwarding frames.
How can a broadcast storm be ended?
One approach to alleviate the broadcast storm problem is to inhibit some hosts from rebroadcasting to reduce the redundancy, and thus contention and collision.
How will Switches find the best paths to the root bridge?
After the election of a root bridge has occurred, each switch will have to determine the best path to the root bridge from its location. The path is determined by summing the individual port costs along the path from each switch port to the root bridge.
What is an accurate description of LAN redundancy?
Explanation: Redundancy attempts to remove any single point of failure in a network by using multiple physically cabled paths between switches in the network.
What is a characteristic of out of band device management?
What is a characteristic of out-of-band device management? Out-of-band device management requires a direct connection to a network interface. It requires Telnet, SSH, or HTTP to access a Cisco device. It requires at least one network interface on the device to be connected and operational.
What is a best effort protocol well suited for streaming audio and VoIP?
Select one:TCPIPUDP SSHRefer to curriculum topic: 5.2. 1User Datagram Protocol (UDP) operates at the transport layer of the TCP/IP model. UDP has no reliability mechanisms, operatesas a “best effort” protocol, and is commonly used with delay sensitive applications such as streaming audio and VoIP.
Which two port numbers could be used to remotely access a network server?
Port 20 and 21: FTP data and FTP control, respectively. Port 22: Remote login protocol secure shell (SSH) Port 23: Telnet, used for accessing system remotely but is not very secure.
At what layer of the OSI model are port numbers addressed group of answer choices?
layer 4
What is the primary motivation for development of IPv6?
The standard specifies that any ICT system within the network has a unique number (IP address) has. The main motivation for the development of IPv6 was to increase the amount of available addresses compared to the present standard predecessor IPv4.
Should IPv6 be on or off?
Others might disable it because of a misperception that having both IPv4 and IPv6 enabled effectively doubles their DNS and Web traffic. This is not true. Therefore, Microsoft recommends that you leave IPv6 enabled, even if you do not have an IPv6-enabled network, either native or tunneled.
Is IPv6 faster than IPv4?
Without NAT, IPv6 is faster than IPv4 That’s in part because of the proliferation of network-address translation (NAT) by service providers for IPv4 Internet connectivity. The IPv6 packets don’t pass through carrier NAT systems and instead go directly to the Internet.
Should I activate IPv6?
IPv6 is extremely important for the long-term health of the Internet. Switching from IPv4 to IPv6 will give the Internet a much larger pool of IP addresses. It should also allow every device to have its own public IP address, rather than be hidden behind a NAT router.
Does IPv6 slow down a network?
Windows, Linux, and other operating systems all have built-in support for IPv6, and it’s enabled by default. According to a myth going around, this IPv6 support is slowing down your connection and disabling it will speed things up.
