According to the system. Disabling interrupts is preferable in some real-time processes, but the interval during which they are deactivated MUST be brief enough to prevent problems.
It would respond in 50 microseconds, whereas using an interrupt would take more over 100. I used it once to handle a somewhat messy device (saving and restoring registers and such). Consequently, a loop without interruptions and with a countdown timer. The device was tagged as "offline" and interruptions were enabled again if the countdown limit was reached. Interrupts were re-enabled if the device responded. Thus, interrupt blocking was quicker and took a manageable amount of time so that other devices weren't starved.

why is it difficult for routing loops to occur in networks that use link-state routing? group of answer choices routers use hold-down timers to prevent routing loops. each router builds a simple view of the network based on hop count. routers flood the network with link-state advertisement to discover routing loops. each router builds a complete and synchronized view of the network.
It is difficult for routing loops because each router builds a complete and synchronized view of the network.
What is link-state routing?Each router in the network exchanges information about its neighbourhood with all other routers using a technique called link state routing. Each router in the network comprehends the network topology in this method, which then bases the routing table on this topology.Each router will transmit information about its connection to its neighbor, who will then transmit it to their neighbours and so on. This appears just before the network topology has been established by all routers.Every node in the link-state flooding method keeps a database of all LSP messages, which prevents the general problems of broadcast in the presence of loops. Each LSP has a creator that includes its identity, information about the link that changed status, and a sequence number.To learn more about link-state routing refer :

a dmz is . a. a trusted network b. a semitrusted network c. an untrusted network d. not actually a network
A DMZ is a semitrusted network. Henec, option (b) 'semitrusted network' holds the correct answer.
In the context of computer security, demilitarized zone or DMZ refers to the physical or logical subnet that separates a LAN i.e. local area network from another untrusted network- commonly the public Internet. The purpose of the DMZ is to provide organizations with exposed, outward-facing services. The DMZ acts as the exposed point to untrusted networks like the Internet.
The DMZ is called a subnet because it occupies only a portion of the network and isolates itself from the rest of the network. It is usually recommended that the DMZ host is to be disabled unless it is absolutely necessary. This way, the network is only exposed for a certain period of time when the DMZ is configured rather than being exposed all the time.

What Does Query String Mean?
The part of a URL known as a query string is used to pass information to a back-end database or web application. Because the HTTP protocol is stateless by design, we need query strings. You must continue to operate a website in order for it to function as more than a brochure (store data).
There are several methods for doing this: You can use something like server-side session state on the majority of web servers. Cookies can be used to store data on the client. You can also use a query string in the URL to store data.
All URLs on the internet can be divided into three parts: protocol, file (or program) location, and query string. The majority of the time, the protocol you see in a browser is HTTP.
The location is represented by the hostname and filename in their typical format (for instance, www.brainly.com/somefile.html), and the query string is whatever comes after the question mark symbol ("?").

suppose a computer using direct mapped cache has 64 kbyte of byte-addressable main memory, and a cache of 512 blocks, where each cache block contains 32 bytes. a) how many blocks of main memory are there? b) what is the format of a memory address? provide the names and the sizes of the fields. c) to which cache block will the memory address 0x2fa map?
a) Number of blocks in the main memory = 2^32 / 2^6 = 2 ^ 26 blocks.
b) block offset size is 6 bits and size of the block filed is 3 bits.
c) The cache has 2 ^ 3 blocks (0 block, 1 block, 7th block), the given address maps to 6th block.
What is address maps?
Address mapping, also called pin mapping or geocoding, is the process of giving addresses in a database a location on a map.
Given that,
a) It is given that the size of the main memory= 2^32 bytes
Cache size = 512 bytes = 2 ^ 9 bytes
And block size = 64 bytes= 2^6 bytes
Therefore number of blocks in the main memory = 2^32 / 2^6 = 2 ^ 26 blocks
b) From the given information block size = 64 bytes= 2^6 bytes
Therefore the block offset size is 6 bits.
Number of blocks in the cache= Cache capacity(C)/ Block size (b)
= 2 ^ 9 / 2 ^ 6
= 8 blocks
= 2^3 blocks
Therefore, the size of the block filed is 3 bits.
Since the main memory is byte addressable and the size of the main memory is 2 ^ 32 bytes, 32 bits are required to refer a byte in main memory.
Tag bits = (size of the main memory address- size of the block field(i.e. index) – size of the block offset)
= (32-6-3)
= 23 bits
Therefore the size of the tag field is 23 bits.
c) Given memory address is (13A4498A)

Since, the cache has 2 ^ 3 blocks (0 block, 1 block, 7th block), the given address maps to 6th block.
