Broadcast frames are layer 2 and not Layer 3, examples are DHCP/ARP/RARP etc.  request.  A Router will block all broadcast traffic unless configured to let the specific packet through via the IP Helper statement to direct to a remote DHCP server and back.
Obviously, a bus topology this is OLD technology they rarely exist anymore. Today, switches have taken over the dumb hubs or even vampire taps on a coax cable. However, a broadcast it still passed on to every port on the switch, unless configured not to do so. Anyway, I could go on and on.

A(n) ____________ is special high-speed memory that allows a microprocessor to access data more rapidly than from memory located
iren [92.7K]

Answer is CPU cache

Explanation: A CPU cache is a special high-speed memory which is smaller and faster, and which helps to store copies of data from main memory location which are often used. It is actually located quite close to the processing core, and is used by the CPU of a computer to save time and energy in accessing data from the main memory.

The way it works is if the processor is either trying to read from or write to a particular location in the main memory, it checks to see if the data from the location is already in a cache, if it is, then it alternatively read from or write to the cache; which faster, instead of the main memory.

Please let me know if this helps.

Pleas help with this question: Which statement about word processing software is true?
deff fn [24]
Short Answer C

The Primary use of any word processor is to create word documents (like this editor) with the ability to format it with bold letters or <u>underlining</u> or <em>italics</em>. There are many other choices of things to do. All your choices are true but the main one is the third one down.

It can do very simple mathematical calculations if it can create tables (neither of which is possible with this editor. A is incorrect.

D is mostly incorrect. Very few word processors have built in capabilities that would help you with word games. There are some that do. Most don't.

I would hate to create fonts using a word processor. It's remotely possible, but anyone in his right mind would try using a program designed for that.. B is incorrect.
