    Long story:
    I'm in a unit in the army that's job is to investigate crimes in the army (from drug usage to weapon thefts). Now, my current position is of an investigator, meaning I need to sit and investigate the people. There's a special unit in our unit that's in charge of fraud crimes and computer-related crimes and offenses, which I am hoping to get into. Problem is, they require a certain amount of knowledge in computer hardware, which I lack. I've started reading randomly in Wikipedia, but we all know how messy that can get (with every new term I don't know I open a new tab, and I get about a hundred tabs in 5 minutes :lol:).
    So I was wondering whether anyone here could give me a simple explanation about computer hardware that I could base myself on, and also maybe give me some direction as to where I could learn more by myself.

    Short story:
    I need to learn about computer hardware. Can you help?

    Thanks anyway!

    I think your best bet would to camp YouTube and go over tons of PC rebuilds. Seeing someone rebuild should give solid outline on internal "guts" of a PC.

    Honestly, though...you TRUE best bet would to build your own systems, then install more than one OS on it (Linux/Unix/Windows/etc multiboot) and start tinkering.

    While I was in the Army, my MOS was 19D (Armored Recon Specialist/Cav Scout), which translated to no future in the real world. I got an old distro of RedHat Linux 5.2 back when RedHat was free (prior to Mandrake), and using forums/maillists/etc, I taught myself the OS and was hosting my own domain, DNS, mail server, SpamAssassin, etc at home on dial up.

    Bottom line....tinkering was better than any training I've had to date and is why I've slowly amassed a small "lab" of old PCs w/ old OSs.

    Considering I get about 93$ a month as payment, and I get home every other weekend (and I have no internet access in my base), I don't really have either the time or the money to buy and build my own PC (I'm assuming that's what you meant? because if you didn't then I lost you)

    Are you looking for books then?

    If it's hardware knowledge you want look for some "A+" certification practice books, for networking go towards CCNA or other types of Cisco books. For Programming look into anything from O'Reilly is awesome (and some of it comes in the form of free pdfs/ebooks).

    If you're just looking for general computer know-how the best advice I can give you is to just jump in and start using the platform. Get to know about how different file systems work and the ins and outs of the intricacies of your operating system first hand.

    If it's computer forensics you want to learn I'm not sure about reading material but I can introduce you to some tools. If you are working with Linux Sluethkit seems to be the most popular. On Windows, FTK and EnCase are the go-to programs for that sort of thing. All of these will allow you to image hard drives, check metadata and file times for a timeline of events, look for data in unallocated space (attempted to be deleted) and much much more. This field can be a lifestyle and there are so many resources out there just keep googling and PM me if you have any specific questions here as this stuff especially intrigues me.

    I'm mostly looking for computer hardware knowledge- Knowing how to build one, take it apart, what does every part do (how does it do it, basically), and similar stuff.
    Immediate reading/watching material would be best (meaning, internet mostly) as I'd prefer not spending much cash if possible, and carrying books with me to the base will be slightly annoying (not to mention I don't have much time to read, so I'm planning on my time at home to learn)
