Few weeks ago, we looked at the engineering process and how it relates to computer building, this week we will look at what each of the components mean.
CPU: The CPU (Central Processing Unit), is the “brain” of the computer system. The CPU is responsible for executing a sequence of stored instructions called a program.
Clock Speed
CPU clock speed, or clock rate, is measured in Hertz, generally in gigahertz, or GHz. A CPU's clock speed rate is a measure of how many clock cycles a CPU can perform per second. A CPU that processes one instruction per second will have a clock speed of 1 Hz (Hertz). Hertz is defined as cycle per seconds.
Cache
The CPU cache is memory stored in the CPU. The advantage of this is that date stored in the cache can be accessed very fast, but is limited to its capacity.
Specs for the Intel Pentium G358
The Pentium has a clock speed of 3.2 GHz (Gigahertz), so therefore this processor will be able to process 3.2 billion instructions per second.
The Pentium has a cache of 4 MB, so there for 4 MB of data stored in the cache will be will be accessed very fast, but the data stored there can’t be more than 4 MB.
Random Access Memory (RAM)
SSD
SSD stands for solid state drive. Compared to regular hard drive, solid state drive provide faster read/write speed. The write speed is how long it takes to save something on to the drive, the read speed is how long it takes to read something from the drive so, how long it takes to open a file that’s stored on the drive.
The SSD that is going to be in this computer will have a read/write speed of 540 MB/s. Therefore you can save and open data from this SSD at a rate of 540 megabits per second.
Cache, RAM, and SSD are all form of storage. While the CPU’s cache provides fast speed, the capacity of the cache is limited, due to how small the CPU is. RAM is the computer’s thinking space, and the SSD is how much the computer can remember or save.
Power Supply
A computer power supply takes in 120 volts of alternating current (AC) from the wall outlet, and converts it into different amount of directing current (DC), to supply sufficient power to the components in the system.

Random Access Memory (RAM)
RAM stands for random access memory. It refers to memory that the microprocessor can read from and write to. When you create something in memory, it’s saved in the RAM.
So the more RAM you have, the better your computer will run. You can think of RAM as the computer’s thinking space, the more thinking space you have, the more you can think. SSD
SSD stands for solid state drive. Compared to regular hard drive, solid state drive provide faster read/write speed. The write speed is how long it takes to save something on to the drive, the read speed is how long it takes to read something from the drive so, how long it takes to open a file that’s stored on the drive.
