Desktop and Laptop Computers - This is one of the most exciting and fun decisions you can make in the world of technology and it is not as hard as it may seem.
Internet, Networking, and Router - Networking is the process of linking two or more computers. This occurs via wired networks (which must have ethernet cables connecting all equipment), or via wireless networks (which require that a cable connects a modem to a wireless router).
Monitors, Display, and Video Cards - Monitors and video cards go together like a horse and carriage. One cannot function without the other.
Printers, Fax, and Copy - Printers today are very affordable with options falling between inkjets, lasers, and multifunction units that come with fax and copy functions.
Laptop and Desktop Memory - RAM and "memory" are interchangeable terms. RAM actually stands for random access memory. Memory and the speed of your computer chip are two of the most important factors in determining your computer's overall speed.
