This diagram, originally by Chao-Kuei and updated by several others since, explains the different categories of software.
Depending on the specific number of internal drive bays and the height of the tower, these cases can be further classified into mini-size, mid-size and full-size tower cases.
One of the biggest considerations when choosing between case sizes is the number of slots and the number of devices we would like to add to those cases. Full Tower Full-tower cases are generally big with a height that is about or more than 30 inches more than 76 cm.
The number of internal drive bays inside these cases can be between 6 and Mid-tower cases are the most widely used computer cases. Mini-cases normally stand at a height of 12 to 18 inches 30 to 45 cm. Expandability is a problem with these cases.
They can hold a monitor on top of the case. SFFs are available in a variety of sizes and shapes, including shoe boxes, cubes, and book-sized PCs. They need to match. The size of the motherboard is often called the Form Factor Catergories of computers there are several standards.
The form factor identifies the size of the circuit board, the location of the slots as well as the location of the faceplate that comes out Catergories of computers back of the computer. The form factor also identifies the location of the holes that are used to mount the motherboard into the system case.
For example, the full tower has more than enough room to fit an ATX motherboard. Mid-tower case can also accommodate an ATX motherboard in most cases.
Mounting holes for both are located in the same place, making them interchangeable in most cases. The faceplate line up to the exact same position as in all other versions of ATX.
The smaller mid or mini tower cases would likely be too small for a full ATX motherboard but should accommodate micro ATX motherboard.
It is derived from Micro ATX and is used in small computer cases. Notice that there is a single expansion slot and the motherboard itself is considerably smaller than the ATX and even the micro ATX. Also notice that the faceplate still line up and the hole positions still match the ATX hole positions.
Theoretically we could take this micro ITX motherboard and place it inside a full tower case. However we usually use a small form factor case for this motherboard. It is used with smaller devices like set-top boxes, car PCs, media centers, and other embedded devices.
The computer case has to be designed for larger than standard ATX form factor. It is longer in order to provide space for two additional CPU sockets.
Notice that the faceplate is on the opposite end. Another difference is that the hole positions are different. Also, the processor socket is slightly rotated so that it is at an angle to the system board.
This rotation is to aid in the airflow across the processor to assist in cooling the processor. As a result, the availability and variety of BTX-compatible components is limited.
The NLX form factor is used in slim line cases that are very short. We insert a Riser Card on the end of the motherboard. Riser Card is then used for expansion cards, so that now expansion cards lay flat rather than being perpendicular to the motherboard.
The riser card does not have built-in ports for audio, joystick, USB, network or modem. Remember When choosing a system case, other than considering the size of the computer that we want, the most important thing is to match the motherboard form factor with the form factor supported by the computer case.
The most common system case type is the tower.
Full tower, Mid tower and Mini tower.Types of Computer Viruses: The Difference Between Malware, Spyware, Adware and Ransomware Computer Viruses Anti-virus programs promise to cover a broad range of things, especially malware, adware, spyware, and ransomware.
Computer virus is a malware program that is written intentionally to gain entry into computer without owner’s permission. These kinds of programs are primarily written to steal or destroy the computer data.
Different types of Computer Operating Systems refer to the collection of various softwares. Every computer possesses an operating system to run other programs present in it. Nowadays operating system has become very popular as it can be found on several devices ranging from personal computers to cell phones, particularly the smart phones.
