Now for my fifth post, what I’ll be talking about is stuff on computer hardware…
THE MOTHERBOARD
The motherboard which they sometimes call it as the logic board is what contains connectors to get the power from the power supply and other connectors in order to host in a variety of devices that have a plug-in. Another part of the motherboard is the bus which is a set of many parallel lines which enables communication among the devices with its plug-in by providing paths for electrical current.
THE POWER SUPPLY (PSU)
The power supply unit (PSU) is what it uses to convert a main AC to low-regulated voltage power for the internal components of a computer.
RANDOM ACCESS MEMORY (RAM)
Random Access Memory (RAM) is a kind of hard drive that is meant for those that want to put in data and other stuff like files. Because of that, not all of its data will be used at the same time but as it was mentioned there can be a lot of it being put on the hard drive. Whatever kind of data that we work with is what we are given at any moment to be stored with which is none other than RAM (often called as “memory). The main advantage of using RAM is take in what we are working on whether if it is data or anything as it make us have less time waiting and have more time being reproductive. The main point of RAM is that it is very fast, so reliable and not only that but everything is put where it is needed. Let’s say for an example that you are working with a bunch of files and data and your computer accidentally shuts down due to a power outage then you should not rely on putting in all of your data into the RAM in case if everything gets deleted. What will hold all of your data and other stuff will be the hard drive so whenever the power on your computer is either on or off by itself it will always be there as it is needed.
THE HARD DISK
The hard disk is what has all of its information that is being kept on your computer. Unlike RAM, which is very fast and so reliable, the hard disk can hold everything forever including your files and data either with or without having electrical current. With modern hard disks, most of them may have billions of bytes of storage space on them which means that you can take in these files to create, save and download either for months or years without even using up all of its storage space that it provides. Whenever you fill up your hard disk, what Windows will start indicating is a small message on the computer’s screen saying that “you’re running low on disk space” due to any problem in advance. But in fact that if the message appears on your computer’s screen, it means that it would not run low until you come down to 800 MB of free embed disk space. Moreover, all of these megabytes of free embed disk space you get can be equal up to 600 floppy disks and that is still plenty of room for it.
REMOVABLE STORAGE OR DISK DRIVES
The removable storage or disk drives is what people use to get information from whenever they work with computers. With the terms “disk” and “drive”, they can often be described in two exact meanings but can help understand what they are meant for. The term “disk” can be described as the storage device which helps to store information and either contain data or software straight from your computer. The term “drive” is what is described as its hardware which runs the disk. With disk drives, each of them can be designed for any type of media that is specific whether if it is either a CD, DVD or hard drive.
USB DRIVES
A USB drive is like a media drive that works slightly different as they use memory cards to take in information and store them onto there. With digital cameras, they also use what are called “Flash” memory cards because they do the same thing as USB drives do such as taking in information and storing them on.
About the USB drives, each of them should be able to do two of the following tasks:
- Write-Take in information and place them right onto the disk
- Read-Get information of data right off the disk
Also, there are four different drive sizes that you can get from an USB:
DRIVE SIZES
1000 bytes (B)->1 kilobyte (KB)
1000 kilobytes (KB)->1 megabyte (MB)
1000 megabytes (MB)->1 gigabyte (GB)
1000 gigabytes (GB)->1 terabyte (TB) (Most common type of drive size)
