Firewalls can't protect very well against things like viruses or malicious software (malware). There are too many ways of encoding binary files for transfer over networks, and too many different architectures and viruses to try to search for them all. In other words, a firewall cannot replace security-consciousness on the part of your users. In general, a firewall cannot protect against a data-driven attack--attacks in which something is mailed or copied to an internal host where it is then executed.

Alternate Answer:
Properly configured firewalls can limit the propagation of worms - a form of malware.  Typically, firewalls are edge or parameter devices (separates network zones) and most viruses and malware targets end points (user workstations and servers).

100 means 100 bps (bits per second). This is the data transfer speed for cables.

These are networking protocols tcp/ip for internet protocal
udp is the data format
ftp is file transfer protocol

typically used by hackers to connect, get the data and do the file transfer.

An objective person can compartmentalize their feelings, and has to in order to be objective. They cannot let their feelings get in the way of their thought processes. They rely on data and facts, not emotion when considering things. Depending on what the "question" is, they may consider the emotions of themselves and others as "factors" but do not allow them to control their thinking.

If a person is getting all emotional, if they're making fast defensive statements, they're not being objective. They may be "rational" but that is not the same thing as objective.

One of the Merriam Webster definitions of objective is: "expressing or dealing with facts or conditions as perceived without distortion by personal feelings, prejudices, or interpretations"

My Answer: No. I find that objective people, are usually,very difficult to have a sensible discussion with.
Most things in life are subjective and anybody who isn't aware of this, is probably, very young, or very limited in their perception and experience, of life.
