How do operating systems
acquire and manage to keep accurate time?

Answers

Answer 1

Operating systems acquire and manage accurate time through Real-Time Clock (RTC) or hardware clock that is located on the computer's motherboard.


Operating systems acquire and manage accurate time through a variety of methods. The most common method is by using a Real-Time Clock (RTC) or hardware clock that is located on the computer's motherboard. The RTC is powered by a small battery and is independent of the operating system, meaning that it will keep time even when the computer is turned off.

When the operating system boots up, it retrieves the time from the RTC and sets its internal clock to match. The operating system then continues to keep track of time using its internal clock, which is typically more accurate than the RTC. The internal clock is updated periodically by the operating system using a time synchronization protocol such as Network Time Protocol (NTP).NTP is a protocol used to synchronize the clocks of computers over a network. It works by having a central time server, which is connected to a highly accurate atomic clock, provide time updates to other computers on the network. The operating system periodically checks in with the time server to update its clock and ensure that it is accurate.In addition to using an RTC and time synchronization protocols, some operating systems also use other methods to keep accurate time. For example, some operating systems use the computer's processor clock, which is a high-frequency oscillator that generates pulses at a very precise rate. The operating system can count these pulses to keep track of time.Overall, operating systems acquire and manage accurate time through a combination of hardware clocks, time synchronization protocols, and other methods. These techniques ensure that the operating system's clock is accurate and reliable, which is important for a variety of applications, including network communication, file timestamps, and scheduling tasks.

Ranking Task: How Star Properties Affect Star Formation
Part B: Provided following are the spectral types of four different main-sequence stars. Rank the stars based on the strength of the radiation pressure that pushes outward as they are forming, from highest pressure to lowest pressure.
-O9
-A5
-G2
-M6

Answers

The strength of radiation pressure that pushes outward as stars are forming is primarily determined by their mass and luminosity, both of which are closely tied to their spectral type. Generally, higher mass and higher luminosity stars will have stronger radiation pressure.

Therefore, the ranking of the four main-sequence stars based on the strength of their radiation pressure from highest to lowest would be:

1. O9 (highest radiation pressure due to high mass and luminosity)
2. A5 (lower radiation pressure than O9, but still relatively high due to high luminosity)
3. G2 (lower radiation pressure than O9 and A5 due to lower mass and luminosity)
4. M6 (lowest radiation pressure due to low mass and luminosity)
Hi! I'd be happy to help you rank these main-sequence stars based on the strength of their radiation pressure during formation. The radiation pressure increases with the star's temperature and mass.

Longitudinal (horizontal when facing down the road) joint should always be staggered how far apart

Answers

Longitudinal (horizontal) joints in asphalt pavement should be staggered by a minimum of 3 feet.

The intersection of two adjacent lanes of asphalt pavement is known as a longitudinal junction. The longitudinal junction should be spaced apart from the joint in the next lane by a minimum of three feet to ensure the life and durability of the pavement. This aids in avoiding the development of a continuous joint line, which might be a weak spot in the pavement and cause early collapse. Staggering the joints allows the pavement's load-bearing capacity to be spread uniformly throughout the whole surface, lowering the likelihood of cracking, rutting, or other types of distress. Furthermore, staggered joints reduce the buildup of water and dirt at the joint, which can potentially cause early failure.

Q4)c) Describe the three-step handshake in TCP connection openings.

Answers

The three-step handshake is a process used to establish a reliable TCP connection between two devices in a network. It involves the following steps:

1. SYN: The initiating device (client) sends a TCP packet with the SYN (synchronize) flag set to the receiving device (server) to request a connection. This packet also contains an initial sequence number that the client will use for data transmission.

2. SYN-ACK: Upon receiving the SYN request, the server sends a TCP packet back to the client with both the SYN and ACK (acknowledge) flags set. The server acknowledges the client's initial sequence number and provides its own sequence number for data transmission.

3. ACK: Finally, the client sends another TCP packet to the server with the ACK flag set, acknowledging the server's initial sequence number. This completes the three-step handshake, and a reliable TCP connection is established between the two devices.

In summary, the three-step handshake in TCP connection openings consists of a SYN request from the client, a SYN-ACK response from the server, and an ACK confirmation from the client, which together establish a reliable connection for data transmission.

To generate the same amount of lift as altitude is increased, an airplane must be flown at A) the same true airspeed regardless of angle of attack. B) a lower true airspeed and a greater angle of attack. C) a higher true airspeed for any given angle of attack.

Answers

To generate the same amount of lift as altitude is increased, an airplane must be flown at "a higher true airspeed for any given angle of attack" (option c).

This is because as altitude increases, the air density decreases, which means that there is less air flowing over the wings to generate lift. To compensate for this decrease in air density, the airplane must fly at a higher true airspeed to maintain the same amount of lift. This is because the lift generated by the wings is directly proportional to the square of the true airspeed, so as airspeed increases, the lift generated also increases. Additionally, the angle of attack may need to be adjusted to optimize lift and maintain the desired altitude.

Answers

The correct answer would be b) Left-hand traffic and Runway 18. When approaching an airport, pilots must follow a specific traffic pattern to ensure safe and efficient arrivals and departures. The traffic pattern direction and runway in use are determined by the wind direction and other factors. In this case, Runway 18 is being used, and left-hand traffic is the appropriate pattern to follow.

This means that all turns in the pattern will be made to the left, and aircraft will enter the pattern from the downwind leg, which is opposite the direction of landing. Left-hand traffic and Runway 22.The choice of traffic pattern and runway for landing is determined by a number of factors such as wind direction, traffic flow, and airport layout. The appropriate selection ensures safe and efficient operations during takeoff and landing.In this case, the correct answer would be a) Left-hand traffic and Runway 22. This means that aircraft approaching the airport would fly a left-hand traffic pattern, which involves making left turns when approaching and departing from the runway.The choice of Runway 22 indicates that the runway direction is oriented at 220 degrees. This is important because it aligns with the direction of the wind and allows aircraft to take off and land into the wind, which provides better performance and control.Option b) Left-hand traffic and Runway 18 would not be the correct choice as the runway is oriented in a different direction than the wind, which could create a crosswind situation, making landing and takeoff more difficult and unsafe.Option c) Right-hand traffic and Runway 18 would also not be the correct choice as it would require aircraft to fly a right-hand traffic pattern, which is less common and may cause confusion or errors in communication between pilots and air traffic controllers.In summary, the appropriate choice of traffic pattern and runway for landing is determined by factors such as wind direction, airport layout, and traffic flow, and selecting the correct combination ensures safe and efficient operations during takeoff and landing.

A network administrator may notice a lower throughput compared to the end-to-end network bandwidth due to the following three factors:
1. Network congestion: Heavy traffic on the network can lead to slower data transfer rates and lower throughput.
2. Latency: High latency or delays in data transmission can reduce the effective throughput of the network.
3. Protocol overhead: Additional data, such as headers and error correction, added by network protocols can consume a portion of the available network bandwidth, resulting in lower throughput.
