Yes they will require different memory than PC's, also being more expensive.
no
There are different amounts of memory capability depending on the type of Mac computer you have. An iMac is going to be different than an iBook. You can also install more memory in your computer if needed. It's best to contact a retail store and talk to someone who specializes in memory to discover how much memory you can acquire with your Mac computer.
Generally speaking, servers usually have more memory than desktops and workstations.
Most people do not require additional virus protection for their Macs. Mac OS X is not invulnerable to viruses but it is much more secure than Windows. I have used Macs for a number of years without any issue, without additional virus protection.
No you can't. Your system memory is something completely different than the memory used by USB Drive.
Windows is better than Macs because it is more compatible with all types of software.
less
No. Pages is used a lot but Microsoft Word would be used a lot more than it. Most people have IBM PCs more than Macs and so Microsoft Word is more common, as it is available for both PCs and Macs, whereas Pages is mainly for Macs.
Hard drives show less memory in Windows and Macs and some utilities because drive manufacturers give drive sizes in decimal (base 10) and Windows and the others use binary (base 2). One megabyte is 1,000,000 bytes in decimal and 1,048,576 bytes in binary. So it's the same amount of memory, just given in different number systems. I'd guess drive manufactures use decimal because it makes their drives sound bigger.
