No, they are not. The reason is that the more users/clients you have on a Peer to Peer network the harder it is to administer it. Everyone is their own administrator and you can't enforce policies, backups, or security easily with a peer to peer network.

Why do old people hate computers?

Some older people don't use computers, many, many do.

Essentially it's because they have no need to use computers. They have gotten along their entire lives and haven't needed one yet, and see no benefit to starting now On the other hand, many "old" people use computers very well, but aren't as likely to play with them. They see them more as tools to get work done. That doesn't mean they don't play at all, though, but they tend to play things like solitaire and word puzzle games instead of WarCraft or GTA. Part of this is an interest thing, and part is that the "younger" people have grown up with computers and game systems, so they have trained their reflexes in ways that the previous generations didn't.

What are the four key components of a computer system with an examples?

Motherboard

connects all the pieces together

Hard Disk

long term memory,stores everything, including files, data...etc

advantage over RAM: data remains even after the computer shuts down.

Disadvantage: Very slow compared to RAM

RAM

(stands for Random Access Memory)

short term memory - When data is needed it is loaded from the hard disk to the RAM for much faster processing.

Advantage over hard disk: Much faster

Disadvantage: loses data when computer shuts down

CPU

(Central Processing unit)

The "brain" of your computer, allows it to "think"

Graphics card:

Helps the CPU in processing graphics.

Example of these components working together:

1. A user opens up a video game ()

2. The CPU processes the click, and loads the video game from the hard disk to the RAM.

3. The user starts playing, the CPU and the Graphics Card now process everything in the game (player movement, environment, etc...)

4. when the player finishes, the data is removed from the RAM.

*of course, the component that connects all these things together is the motherboard

Note that there are a lot more components such as the power supply, Cd drives and more...

Apps of computer systems and techniques to gather legal evidence?

Being somewhat of computer expert, I've been told to stay away from this field. Unless you hold specific qualifications as an expert in data recovery (and such), your efforts can be challenged in court (and probably thrown out).

There are many very specific techniques to data recovery, including but not limited to keeping the device in it's recovered state until the process is ready to begin (like keeping a plane's black-box in salt-water until delivered to the recovery team).

Additionally, there is specific hardware designed to *never* write to the media, but only read from it. This is not the same as hooking up a hard drive to your existing computer, because your OS is likely to try to write some information to the "data" drive. Once that happens, your findings are useless.

In the old days disks had write-protect jumpers and such, but not these days.

You can search for apps to recover deleted data (there are lots of good freeware programs out there that I've personally used and have worked great), but it will never pass in court.

Maybe someone else will follow-up my post with a better answer.
