Greeting to all visitors!
This weekend we would like to get you to be familiar with your own PC. PC or Personal Computer is our everyday usage tools and for a geek, it might consider as a girlfriend 😀 Before a Computer Science Professor get crazy to our discussion here, we just want to keep it clear that all information delivered in this blogs are based on our experiences in real work environment and a simple way to deliver the knowledge. So it might be astray from what you will learn in your university Computer Science lecture. So here we go!
5) Power Supply Unit (PSU)
6) Screen Display
Motherboard or known as Mobo for short. Yes, it is the real abbreviation by the way. Like its name, you would never exist without your mother, so as PC. Typical motherboard consist of processor, ports, bus and made up from a PCB. Even though some of them are shipped without on-board processor installed, for you to choose the suitable processor based on your need. Criteria to be look forward when purchasing or choosing a motherboard are, Chipset range, Memory modules, PCI slots, ATA port (Serial or Parallel) and number of USB ports.
Processor or CPU (Central Processing Unit) is the brain of your computer. Like human, processor will determine the ability and capability of your computer to process your task. Well known manufacturer for PC processor are Intel and AMD. There are variety of chipset made by them. In general, they are distinguishable by chipset, architecture (x86/x64), processing speed, power consumption and heat dissipation. Averagely, the processing speed for conventional CPU are between 1GHz to 3GHz. So, is higher processing speed means that the CPU is better? definitely yes! but they come with higher price too. If you have tight budget to build your PC, you might be okay with less speed CPU like Intel Pentium or Dual Core.
Most popular things that perhaps everybody with PC knows are Flash Drives or generally known as a storage. What not everybody knows are they come with 2 version, HDD and SSD. HDD stand for Hard Disk Drive which obviously run using disk and electromechanical components. Oppositely, SSD which stand for Solid State Drive run without any mechanical components which make them more stable and durable for harsh condition and it is pretty fast too. However, because of they are just coming to market around 5 years ago, the price is a bit higher compared to standard HDD. Computer manufacturer such as Apple are taking the speed and durability advantage from SSD for their latest product. However, keep in mind that even though SSD is durable, they are not prone to corruption and breaking. If lost in data is not an option, we suggest you getting RAID instead which is a minimum 3 and more low-cost HDD that store your data redundantly. The theory says that all 3 or more HDD would not break at the same time but who knows right? 😀
Input and Output, I/O
Your mouse and keyboard are the perfect example for Input and your monitor and printers are the example for Output. Input and Output can be split into 2 types, Serial and Parallel. Why there are 2 types? well, before serial coming to gameplay, parallel is the king. Parallel I/O would be mean faster transfer rate of data or latency but this would result in bigger motherboard to connect all cables for each devices. In modern era where more device are connected to each others, one motherboard need to handle more than one device without taking a lot of spaces. Therefore, serial I/O were invented.
Power Supply Unit (PSU)
Any digital devices need a power unit supply. In PC world, they are known as Power Supply Unit (PSU). PSU comes with variety of wattage, but same voltage level which is 24VDC. With more power could be supply from a PSU, that would mean there will be a lot more heat dissipation. So make sure your PSU and PC components have good ventilation to prevent humidity level goes up. Why? when there is humidity, water droplet would happen even in micro form. It is no good to PC which known to be unfriendly to water.
Some computer doesn’t need a monitor at all such as a Server. But for a regular PC, a screen display is a must 😀 Screen display or called as monitor comes with choices of screen size and pixel density. Bigger screen does not guarantee a crystal clear display but pixel density does. Ironically, larger pixel density sometime does not guarantee it either because of their poorly written software by developer and manufacturer. Typical usage of monitor size in a regular workplace would be 19″ to 21″. Our favourite monitor would always be Dell, HP and IBM since it has professional and humble looks but have good quality and excellent after sales service.
Cables always been a factor that is intangible to your PC performance. Poorly cable bought from street alley would not deliver the same results as the quality one. Some say they are all the same, but as a PC user, you should know basic of purchasing cables for your PC components. You can see a quality cable have long lasting usage compared to cheap one. Before purchasing a cable, you should know what it will be use for. For monitor, the typical cable connection would be DVI, VGA and HDMI. For keyboard and mouse, it would be USB2.0 and USB3.0. Manufacturer such as Apple even have port for USB type C for their Iphone and Macbook. So make sure you know which USB you are talking about. One thing you should know also is American Wire Gauge of known as AWG. This is a worldwide standard for cables rating in power and size.
