The motherboard is the computer's main circuit board as shown in figure 8. It's a thin plate that holds the CPU, memory, connectors for the hard drive and optical drives, expansion cards to control the video and audio, and connections to your computer's ports (such as USB ports). The motherboard connects directly or indirectly to every part of the computer.
The most common type or ROM in a computer is the BIOS. The basic input/output system is a program a computer uses to startup a computer. The BIOS controls the data flow from the computer’s operating system and the connected devices. However, before the computer can start up, it must go through the POST process. The power on self-test process is a diagnostic test performed by the computer that will notify the user if any attached device
This memory is assists in allowing the computer to simultaneously read and write data at the same time. Simply put, RAM is the most common form of memory that is utilized by computers as well as other devices. There are specific types of RAM that include dynamic random access memory and static random access memory, or DRAM and SRAM respectively. These two RAM are very different in terms of how they allow data to be read and written. Dynamic random access memory is often considered the most frequent type found in computers. Static random access memory is also found in computer, and is usually referred to as the faster of the two types due to the fact that refreshing of this form of memory is not needed whereas with dynamic random access memory it is. The term RAM is often used to describe what the computer uses to function. It is the main memory or primary memory whereby all processes and software run. Since it is random access memory, it is only available at the time a certain process is needed and is not stored anywhere on the computer specifically (2007). This is what makes random access memory often confusing to understand particular since computers also have what is known as read only
Everything you add later such as word processors, antivirus software, e-mail software, games, and internet software are extra, soon leading to an over stuffed filing cabinet (Matthew Ferrara Seminars). However, many people ask, “What is the hard drive, physically?” The hard drive can be commonly referred to as “a box”. That is what it looks like, a three and one half inch metal box. It is located inside your mainframe or tower. It sits in what is called a drive bay. Here it is secured with screws. On the bottom of the hard drive is a chip board which is the really technical and complicated pieces of the hard drive.
Computer hardware can be any part of a computer that you can touch. This includes the keyboard, monitor, mouse, floppy, hard drive, and all the pieces of electrical, physical, and mechanical components. While there are many different versions and manufactures of system components, the basic components are the same.
RAM – stands for Random Access Memory, since it enables you to access any memory cell directly so long as y...
