Approximately 2000 luminous photons are produced for every 25 keV accelerated electron that strikes the output phosphor when it is struck by an electron.
When the input phosphor emits light photons, what does the photocathode emit in return?When light photons hit the input screen's photocathode, photoelectric interactions absorb them, causing the photocathode to emit photoelectrons (via the photoelectric effect). By creating an electric field between the photocathode and anode, the electrons are propelled in the direction of the output fluorescent screen.
The photocathode's function is what?A thin coating of an antimony and cesium alloy serves as the photocathode in an image intensifier (SbCs3). Through the PE effect, the photocathode transforms the light photons released by the entry phosphor into photoelectrons.

OB. It could perform any task that was asked of it, including data
crunching, word processing, and calculations.
OC. It was the first computer to successfully connect to the World

Answer:
D. It was designed to contain parts that helped establish the design
principles of every modern computer today.
Explanation:
The Analytical Engine, designed by Charles Babbage in the 19th century, is considered to be the first computer ever designed because it was the first machine to contain many of the key components of modern computers, such as memory, a control unit, and the ability to perform conditional branching. It was also the first machine to be programmable using punched cards, a precursor to modern programming languages. These design principles laid the foundation for the development of modern computers, which is why the Analytical Engine is often considered to be the first computer ever designed.

you have just finished installing windows server 2016. you have assigned the server a name and finished configuring ip addresses. you have tested your configuration by using ping to verify network connectivity with your default gateway and another server on the network, and everything worked fine. however, the next day, a colleague tells you that when she tried to ping the server, her request timed out. you try to ping her computer and receive a reply just fine. why can't your colleague ping your server successfully?
There could be a number of reasons why your colleague is unable to ping your server successfully. Some possible causes include:
Firewall issues: Your server's firewall may be blocking incoming ping requests.
Network configuration issues: The IP address or subnet mask of the server may have been configured incorrectly.
Router or switch issues: There may be a problem with the router or switch that is preventing the ping request from reaching the server.
Network segmentation: the server could be located in different VLAN or subnet and the colleague is not able to reach it.
DNS resolution issue: the server name may not be resolving to the correct IP address.
Other network devices: there could be other network devices along the path that may be blocking or filtering the traffic.
It is recommended to troubleshoot the issue by checking the server's firewall settings, network configuration, and checking the connectivity with other devices in the network. It would also be helpful to check the logs of the network devices and the server to see if there is any indication of the issue.
The possible reasons that one cannot log into the server is:
1. Firewall settings
2. IP address conflict
3. Network configuration changes
4. Network connectivity issues
5. DNS resolution
6. Network isolation or segmentation
The possible cases can be as follow:
1. Firewall settings: It's possible that the server's firewall is blocking incoming ICMP (ping) requests. Ensure that the appropriate firewall rules are configured to allow ping requests.
2. IP address conflict: It's possible that another device on the network has the same IP address as your server, causing conflicts and preventing your colleague from reaching your server.
3. Network configuration changes: Check if any network configuration changes have been made since the initial successful ping. This includes changes to IP addresses, subnet masks, or default gateway settings. Ensure that the network configuration is consistent across all devices.
4. Network connectivity issues: Examine the network connectivity between your colleague's computer and the server. There might be network issues, such as a disconnected cable, faulty switch port, or network congestion, preventing successful communication between the devices.
5. DNS resolution: If your colleague is using a hostname to ping your server, check the DNS resolution. Ensure that the server's hostname is correctly registered and resolvable in the DNS system used by your colleague's computer.
6. Network isolation or segmentation: Check if there are any network policies, VLANs, or other configurations that could be isolating or segmenting your server from your colleague's computer.

consider a 128 kb 8 way set associative cache with 32 byte lines. both the virtual and physical address spaces are 36 bits in size. how many bits are used for the tag comparison, set index, and byte offset
The number of blocks in the cache (12 bits in this example because 212=4096) serves as the index for a direct mapped cache. Then, all of the bits that are left comprise the tag.
How do I determine the size of a cache line?A memory block corresponds to each cache line or slot. That indicates there are 16 bytes in each cache line. 64Kbytes/16 = 4096 cache lines if the cache has 64Kbytes.
How is the cache determined?The most accurate technique to determine a cache hit ratio is to divide the total number of hits by the total number of hits plus the total number of cache misses. This statistic is typically expressed as a percentage of the hits or requests to the relevant cache.
