A Bit about Memory Bytes
Memory is the most important factor in determining how fast your computer runs. Computers use Random Access Memory (RAM) to store and access the operating system, programs, and data. The Intel processor usually has the following amounts of RAM (main memory):Linux can run on a surprisingly small amount of memory. With some work and no graphics, you can squeeze Linux on an old PC with only 16MB of memory; 32MB makes life much easier and your computer significantly faster. Many people use old PCs with small amounts of memory as simple network servers.
If you want to run Linux with graphics, however, you need 64MB.
With 128MB, Red Hat Linux runs multiple graphical programs, like OpenOffice, with ease.
You need 256MB or more (many PCs now come standard with 512MB) for hard-core computing. Using big applications, such as VMware, make having enough memory essential.
TipVMware virtual computers need their own RAM to operate at a reasonable speed; for example, you should allocate a minimum of 128MB of memory to run a Windows 2000 virtual computer. Plan to use 512MB if you want to run multiple instances of VMware virtual computers.
You can install Red Hat Linux on most laptop computers by using the notebook’s built-in CD-ROM drive, or a PCMCIA, USB, or proprietary CD-ROM drive. If you don’t have any of these items, you can try to get a PCMCIA Ethernet controller and do a network installation, as long as another Linux system on the network has a CD-ROM drive installed. If that is the course you take, consult the Red Hat installation documentation at www.redhat.com/support. You also need a video card that Red Hat understands. Red Hat Linux supports most video cards, and usually the only problems result from bleeding-edge notebook computers that use the latest and greatest video hardware. You can use the generic VGA, XGA, or SVGA drivers that Red Hat supplies if you can’t find the specific driver.
