Almost every device has a computer within it, but very few people know the ins and outs of how it operates. Knowing the logic behind a computer system is a great way to understand how these systems work and begin constructing some new knowledge bases. The basic design that computers are made from is in fact rather simple compared to the pieces themselves, since there is just a basic flow of information.
The central processing unit, or CPU, is the core brain of the entire system that enables it to work. Much like the brain, the processor has many different levels of memory and is the place where info is processed. Computers today are advancing by adding more cores, which are basically entirely separate processors in one single chip. There are also multiple layers of cache memory integrated into the processor that act like a higher level of system RAM. The idea is that these degrees of cache will store frequently requested processes and use that information rather than reprocessing it repeatedly. The level 3 cache will generally be more plentiful but be slower, whereas the level 1 cache will be speedier with less storage space.

After the level 3 cache there is the system RAM, which is basically a separate component entirely. To read the information, a system will load a program when launched into the system's RAM instead of reading it all from the hard drive. Even though loading to the RAM is where a lot of the wait time is spent when opening a software program, without it, many different things would not be possible as things would be so slowly pulled from the hard drive. When the computer system is turned off all the information in the RAM is erased, and because of that a hard drive is required to permanently store information.
Storage is the primary function of the hard drive even though it does work as an even lower form of RAM sometimes. There are many other components that are not exactly essential but serve a very useful purpose. The network card allows a PC to connect with a network of systems to share files or gain access to the Internet. While data centers require many Cisco GLC-T or other SFP transceiver modules to function efficiently, most home systems get away with using a single Ethernet port per system for communication. In order to make a sound and picture a video and sound card are essential. There is also the motherboard which consists of many connections and processors to do certain tasks and hook everything together.
