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.

LINQ defines standard query operators that allow code written in LINQ-enabled languages to filter, enumerate, and create projections of several types of collections using the same syntax. Such collections may include arrays, enumerable classes, XML, datasets from relational databases, and third party data sources. The LINQ project uses features of version 2.0 of the .NET Framework, new LINQ-related assemblies, and extensions to the C# and Visual Basic .NET languages. Microsoft has distributed a preview release of LINQ, consisting of those libraries and compilers for C# 3.0 and Visual Basic 9. Other languages, such as F# and Nemerle, have also announced preliminary support.

A database index is a data structure that improves the speed of operations in a table. Indices can be created using one or more columns, providing the basis for both rapid random lookups and efficient ordering of access to records. The disk space required to store the index is typically less than the storage of the table (since indices usually contain only the key-fields according to which the table is to be arranged, and excludes all the other details in the table), yielding the possibility to store indices into memory from tables that would not fit into it. In a relational databasean index is a copy of part of a table. Some databases extend the power of indexing by allowing indices to be created on functions or expressions. For example, an index could be created on upper(last_name), which would only store the uppercase versions of the last_name field in the index. Another option sometimes supported is the use of "filtered" indices, where index entries are created only for those records that satisfy some conditional expression. A further aspect of flexibility is to permit indexing on user-defined functions, as well as expressions formed from an assortment of built-in functions.
