The technical specifications offered by Macs and PCs can be very similar or very different, depending on which brand and line you're comparing. While they both have similar internal parts (processors, RAM, hard drives, video cards), the speed and capacity of these components vary. Macs will generally outperform low-end PCs, because the Apple product lines typically boast more expensive and better-quality parts. Comparing Macs with higher-end PCs is a little more difficult. Generally, though, Macs have faster processors than their Windows counterparts but tend to skimp slightly when it comes to RAM, hard disk space and USB ports.
The kinds of connections and optical drives found on Macs and PCs also differ in certain ways. Macs offer a pretty standard selection of such features, including a SuperDrive (reads and writes CDs and DVDs), audio in and audio out, USB, FireWire (data transfer), Thunderbolt (video output), Ethernet, and a magnetized power port. PCs offer comparable features, plus a few more, like Blu-ray players, TV tuners, touch screens and HDMI ports.
