Alton Kerry 18470825 Unit 4 Research Paper – Port Expander A port expander is computer hardware that allows you to plug more than one device into a single port. It can be any device that takes one existing port and makes multiple ports out of it. There are two basic forms, internal expander which has a connection typically to the motherboard, and an external expander which plugs into the existing port which then has multiple ports. When not part of a computer, these devices are known as splitters. In the non-computer world splitters are very common, such as an extension cord or a power strip.
The motherboard also has expansion slots most commonly used by audio and video cards, although the slots can be utilized by many other types of cards. You also find mass storage ports for hard drives, CD-ROMs, and DVD-ROMs on the motherboard. Functions of motherboards: The motherboard is where all the major component of the computer is held. It is the central meeting point of all technologies in the computer. It serves as a circuit board that connects and communicates to all devices and components attached to it.
However, suppliers of production material for PCs have less power. There is a low cost of switching suppliers, and there are similar production inputs available which reduces firms being locked in to certain suppliers. So in this case the bargaining power of suppliers is a weak force. Overall, the bargaining power of suppliers is a moderate force in the PC industry. The fact that PCs have such a large customer base that ranges from government to business to personal use means that the bargaining power of individual customers is low.

A port expander is a device that allows one port on a computer system to connect to multiple devices. There are two basic forms of port expander: internal and external. An internal expander has a connection inside the computer, typically on the motherboard, and the only part the user sees is the expansion plate containing multiple ports. An external device plugs into the existing port and then has multiple places to connect. .
Manages Applications – each OS installs, uninstalls, runs applications and manages the interface to the hardware for an application. 4. Manages Hardware – each OS manages the permanent programs and memory. All three OS’s also diagnose software and hardware problems and interpret the needs of each. With the similarities in the forefront of our minds, let us delve into the depth of the differences in the Linux, Mac, and Windows operating systems.
One example of a business where IM will not work is a business that that sells electric wheelchair. Additionally, companies looking to sell products to a wide range of people and are looking to have large number of sales will not find IM as useful as outbound marketing (OM). While IM is good because it is cheaper to imploy and brings in higher value potential customers, it only captures a small market. OM should still be pursued if a company is seeking for large sales and large customer base. The most optimal marketing strategy may still be to apply both methods of marketing with the right
Household machines come either mechanical or computerized. Mechanical tend to be cheaper, less versatile, and last longer. Computerized machines are more expensive, and have much more functions. Industrial machines are designed for efficient garment construction. They tend to save money and time.
It’s far cheaper than using mainframes and big servers and at the same time very easy to access and maintain. Grid computing is a technology used to harness computing powers from various sources and use them in harmony to achieve a specific goal. The great advantage of grid computing is the ability to significantly reduce the time that is taken to accomplish that goal, also increasing efficiency. Educational organizations like colleges and universities can use grid computing and support their online teaching program. By doing this they can bring all the students together in one forum and solve problems and have discussions.
