How to upgrade Mac Mini 2006 (mac mini 1,1)?

The first question is, "Can you upgrade your Mac Mini 2006?" The answer is YES.

Is it worth to upgrade? Well, not much but at least you can increase the processing power of your Mac Mini and extend its usability to the needs of modern computing.

What is Hyperthreading and what are its Benefits?

Hyper-threading technology from Intel has been on their computer processors for over 10 years and yet much same as the elusive Fox, most people know very little about what it says. Let us start with an analogy. Let us say I am a CPU and I am trying to process food, or eat as some people call it. I can only do as much eating as one mouth can do if I could add more mouths than I could process more. This is what multi-core processors do but due to cost constraints among other things, it is not always possible to take that approach, so I have got just one mouth I can use my hand to pick up the food, bring into my mouth, then grab another bite while my mouth is busy. If I finished chewing before my hand is ready to deliver me more food, however, then my mouth is just sitting there doing nothing. If only I could use two hands to prepare food for my mouth then even though my mouth cannot actually work any faster I would not waste any time. Oh wait I can do that.

What is Bottleneck or Bottlenecking on your PC System?

A BOTTLENECK occurs when there is some restricted element holding back the performance that could otherwise be achieved. Fluid flows much slower through the neck of the bottle than if the neck does not excess. Another word for a bottleneck is the CHOKE POINT.

Let us start with a couple of examples. In a vehicle, the traction between the tires and the road is important for optimal power delivery between the engine and the road making the car move forward. Now an example where traction would be a bottleneck if your engine were so powerful and then you go to accelerate, the wheels just spin. Now at high speeds a wing could improve traction by using airflow to force the rear of the car down towards the road. This can alleviate that bottleneck. That sounds great!

How to choose the Right PC Power Supply (PSU) for your system?

A computer power supply is almost as mysterious as the phrase, “I'm fine just leave me alone.” I mean, what does that even mean? If I actually leave you alone to go play video games, will I be making a huge mistake and like pay for it later. I mean if you were fine wouldn't you want to talk to me like you normally do and if you're not fine when it blows up later, will it be your fault for not communicating clearly or my fault for not understanding? Please tell me what you want.

Anyway, while I am not qualified to help you understand women, I can help you choose the right wattage of power supply for your PC.

When to Upgrade your RAM or Computer Memories?

You might say, “I need more RAM that will make my computer go faster.” Wrong! More RAM can improve performance and there was a time when it usually would but those days are gone. Modern computers, even ones that are two to three years old, often have enough RAM for the basic tasks that users want to perform.

So how would you know if you do not have enough memory causing your system to slow down? Check out the Performance Monitor in task manager (CTRL+ALT+DEL on Windows).

How to convert Laptop into Desktop PC?

I will tell you how I built a desktop computer using the motherboard from an old laptop that had a cracked LCD and a broken hard drive. I used Acrylic Alumina thermal adhesive to paste a big piece of aluminum on top of the CPU. It is actually glued on top of the heat pipe that is cooling the CPU.

Do you need more Pixel Density (PPI) or Retina?

Resolution is often the only specification quoted when referring to the finest of a digital image but there is actually much more to it than that. A five-inch 1280x720 image will look sharp and crisp on your phone but if you project it as 720p image in a movie theater, it would look horrible. This is where pixel density comes in. It is a measure of the resolution that also accounts for the size of the screen. PPI has become the most common way to denote pixel density although pixels per centimeter or PPC can also be used. To calculate PPI, simply measure 1 inch diagonally on the screen and then draw a line diagonally through them, and find out how many pixels it intersects with.

How to build a Low Power Consumption PC – Green PC?

I am very interested in green computing and in particular, in low-energy PCs. Today, I am going to show you the construction of my own Green computer. Let us begin by looking at the components I bought to build this energy-efficient PC.
