Have you ever wondered how computers actually work? Not too long ago in our history computers would take up entire rooms and had only enough processing power to do a few simple calculations. Now we can fit computers, with more processing power than the computers that sent a man to the moon, in our pocket.

Most people use these machine without any understanding of how they are put together or what the individual components inside actually do. It might as well be magic as far as they are concerned. And it’s understandable. Computers are complex machines. Not easy to understand.

So we are going to virtually deconstruct a typical PC and go through what each of the components actually does. We will be explaining it in layman terms as well, so don’t worry about getting bogged down with a lot of technobabble.

The Motherboard

You will hear the motherboard mentioned in connection with nearly every other component inside of a PC. The motherboard is, essentially, the large piece of circuitry that all the other components rest on. It is the section of the PC that it attached and fitted inside the case itself. It acts as a body for the machine, allowing all the individual components to do their job in tandem. This does mean if the motherboard gets damaged, the whole system can stall out and break.

 

The CPU

If the motherboard if the body, the CPU is the brain. Without this, you don’t have a PC. CPU stands for central processing Unit, not to be confused with the processors. The CPU is where all the commands are issued from. It controls all the other components and is what generates the information you see on your screen. When ever you click your mouse, the CPU passes that information to the relevant section. If you open a program, the CPU will start the code and activate it. The more powerful your CPU, the faster your machine will run.

 

Processors

The CPU handles all the big tasks, but a computer also has to carry out an insane amount of calculations a second, and the CPU cannot handle this alone along with managing all your apps, tasks and the other components. This is where your processors come in.

Processors do all the busy work. All the calculations or background checks the CPU is too busy to handle. The CPU is the queen and the processors are the workers bees. Having more processors will make your machine far more powerful, which is why you often see Quad-Core touted as a great thing to have.

RAM

The most common question I get asked is, what is RAM? RAM stands for Random Access Memory. Imagine it like a massive box of thumb tacks. And every time you need to open a program you need to tack it up on the wall. This is how RAM works. It is spare memory used only to run different programs.

Programs need to store information while they are running. And if they stored it on your hardrive it would slow down you machine constantly. So instead that information is stored on the RAM drive and then deleted once the program closes.

The more RAM your machine has, the more programs you can have open at once without issues. You also need a lot of RAM to run high-end games. So if you are building a PC make sure you check out the best ram for your PC on this German site.

 

Hard-Drive

Chances are you know what this one does. But for anyone who doesn’t, that’s OK. Simply put the Hard Drive is the memory center of your PC. It is where everything permanent is stored. The CPU knows how to run programs but is only a tiny chip. The Hard Drive is where the code is kept.

It is also where you store all your documents, music, photos and videos. You might also have heard the time SSD, which stands for Solid State Drive. These function the same as a hard drive, but allow for quicker memory retrieval and are far more powerful.

 

The Fan

I have said that the CPU is the most important part of the computer, and this is technically true. But for the survival of a PC, the fan is the most important part. CPU’s run hot. It is a side effect of the sheer power of the computations that go on within the case. Not to mention anything that uses electricity is going to run hot as it is.

The more your computer is processing, the hotter it gets. And if it gets too hot it can overheat and die. So the fan, as you can guess, keeps the system cool and functioning. The cooler a CPU is kept, the greater its efficiency.

 

The tech industry is known to be a world that values who you know more than what you know, and once you are in you are never really out. This comes as a challenge to those who may not have links to the tech world, and no real route of actually getting in. The tech industry is a cut-throat place and you will need all the help you can get; so as an insider who has experience within the tech industry I will provide you with all the skills I have learned to help you get that dream tech firm job. So, here are my biggest tips.

 

Always be Honest

First and foremost, you must always be honest. Tech firms value honesty like gold dust, and if you think that these tech firms won’t use powerful software to dig into your past then you are mistaken. Tech firms strive for honesty and there are numerous cutting edge background checks that these companies will use; I mean just look at this Http://www.kyshrm.org/employment-background-check/, so if you want to get anywhere near the interview room just be honest! And remember the tech industry is a small place so if you lie to one firm it is almost a certainty that others will find out, and you will tarnish your already small reputation. Tech firms are extremely secretive places so a potential employee must show a true streak of honesty. So, try to stay clean and stay true.

 

Communication

Like almost all forms of life, communication is key, and this is no truer than in the tech world. It is one of life’s great myths that all techies are asocial nerds, this simply cannot be further from the truth. Tech firms hold great value in an applicant’s social skills as it is highly likely that they will be working in a small team, where chemistry is pivotal. So do not be afraid to show confidence and extroverted nature, these assets are necessary to the functioning of any tech firm.

 

 

A Multi-Talented Individual

It is no longer enough for an individual to be great at just one thing, an employee must now be a swiss army knife with great abilities in multiple different sectors. So, do not just focus on coding or just software engineering at college. As tech firms get smaller and smaller, a potential employee must show great ability in numerous aspects of the tech world. When I first started out this was something that was not necessary. You did your job and you were fine. Nowadays, an employee is expected to do five different jobs at once!

 

Experience

Finally, the most important attribute that a tech firm will look for is experience. This experience will come from internships. There are things that college will simply not teach you. You need to feel the rhythm of the workplace environment and showcase a true understanding of the tech world. Tech firms are always looking for free labor, so while at college try to apply for as many internships as possible. Though the work may feel steep the rewards are numerous and this experience will shine brighter than any grade on your resume. I remember when I got my first tech job, I was specifically told that my experience in the field, from my internships, was what truly made me stand out.

 

So, for any potential Bill Gates or Tim Cooks, remember to build yourself as an individual in both the personal and the professional; and I hope that these tips can help you get that first foot in the door.
