Short Response
Discuss where a computer stores its basic hardware settings, why it does so, and what some of those settings are. A computer is a very complex and complicated piece of equipment that take teams of professional’s to manage. What people seem to forget is even this enigma of hardware also have a very basic system that fires it up. This is called the BIOS (Basic Input/Output System). As the name suggests, it’s a basic function of just turning the hardware on in a particular order. It is no more complicated than the light switch in your room or the ignition in your car. A switch is closed, a piece of hardware receives a power on signal and starts its job. Compare storage devices using four criteria: versatility, durability, speed, and capacity. To keep this answer basic, I will discuss the basic types of storage devices made available to us today. In the current year of 2015, we have “Solid State Drives” and “Hard Disk Drives”. With HDD’s, you can achieve very high storage capacities, moderate durability, moderate speeds, and good versatility. HDD’s are great for mobile PC’s and workstations that need to contain large amounts of data, while not needing the speeds of a SSD. HDD’s have their faults of being fragile and slow read/write speeds, but can be almost as fast as a SSD if purchasing a specific type of HDD. The other type of storage device is SSD’s or “Solid State Drives.” Solid state drives use multiple NAND Flash chips inside of it to hold memory. SSD’s are very compact, use no moving parts, but are limited by capacity and read/write cycles. SSD’s are commonly used in phones, smaller PC’s, USB flash drives, and small devices such as cameras and TV’s.

Please explain the differences between RAM and ROM. Where are RAM chips usually configured? Why are RAM chips considered to be volatile? Before we begin to discuss this question, let’s form knowledge of what RAM and ROM is. RAM is an acronym for “Random Access Memory” which is just as the name suggests, it’s a fast, random form of memory that is constantly being written to and read from. ROM is also an acronym for “Read Only Memory”, just like RAM, is self-explanatory being that it is memory that will only be read from, not written to. RAM modules are usually placed near the CPU because RAM is the “Waiting Room” for the CPU. When something large needs to be processed, it is queued into the RAM to be fed into the CPU for efficient processing. Think of it as being in your car. You need to get up to 60MPH, so you gradually accelerate. You cannot accelerate to 0-60MPH in just a fraction of a second, or you will more than likely experience extreme G-force and lose control of the vehicle. The same applies to a CPU. A CPU cannot suddenly process a large file in one huge sweep, or you will experience a system failure and possible loss of data. RAM is there to slowly (and I say slowly loosely as there are millions of things processing in the midst of this) feed the CPU the information so it can efficiently process your information at a optimal speed. Define storage mediums and storage devices. How are these different from one another? Provide at least three examples of both and elaborate on the purpose of each. Storage mediums and Storage devices are indeed, two separate objects that do different functions. A Storage Medium is something that simply holds data varying between a HDD to a stone slab. A Storage Device is something that reads the Storage Medium. This can be a record on a record player, the record being the medium and record player being the storage device. A HDD is a type of Storage Device that houses silicon magnetic platters, the Storage Medium. The Platters house the actual information in magnetic sections, hills, and valleys. The HDD itself reads with a mechanized arm that goes back and forth over the Medium to translate to an...
