Recommended: Main component of the computer
The three main components of a computer are as followed: Central Processing Unit (CPU),Primary Storage (Main Memory) ,and Secondary Storage (Secondary Memory). The first component of the computer is the Central Processing Unit or known as the CPU. The CPU manipulates the data and controls the tasks performed by the other components. The CPU sequentially access programs instructions, decode them, and controls the flow of date to and from the ALU; the ALU is the Arithmetic-logic unit (this performs mathematics calculations and make logical comparisons). The CPU also access programs such the registers, the caches, primary, secondary storage, and various output devices. The register is a high-speed storage area that store very small amounts of data and instructions for short periods of time. The cache memory is another type or high-speed memory which enables the computer to temporarily store frequently used blocks of data. The CPU works like this. The first step is that it inputs data and brief instructions about what to do. The CPU instructions come from the RAM or Random Access Memory. Some of the data can be entered by the user with a keyboard and mouse; these instructions are then stored in registers until they are sent to the next step. The second step the CPU does is it sends data with the use of a chip via the electrical pathways called buses. A bus is “a set of physical connections (cables, printed, circuits, etc) which can be shared by multiple hardware components in order to communicate with one another” (http://ccm.net/contents/375-computer-bus-what-is-it). A bus is used to reduce the time of with data is sent from a chip through. The third step of a CPU is to control the flow of data and instructions within the chip.... ... middle of paper ... ...ving locally installed software. A thin client if it needs information would access it through the network server rather than accessing through a disk drive. The thin client is less-expensive and easier to operate and support than PCs. Some of the benefits of a thin-client is that they are fast at application deploying; they are more centralized management involved; lower the cost of ownership; and they tend to easier to install, manage, maintain, and support. However there are some disadvantages that they must be aware of, and this tend to be the main issue is if the network fails due to outside sources and/or crashes, or problems that come about, no one on the network using a thin-client would be able to access anything on their computer. While those who use fat clients would still be able to use their computer; due to having the software stored on their computers.
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
Computer hardware engineers research, develop, and test computer systems and components such as processors, circuit boards, memory devices, and many more (Bureau of Labor Statistics). They design new computer hardware, create blueprints of computer equipment to be built. Test the completed models of the computer hardware that they design. Update existing equipment so that it will work will new software. Oversee the manufacturing process for the computer hardware. Maintain knowledge of computer engineering trends and new technology(Bureau of Labor Statistics).
Thin-client computing now offers real hope for progress. The state of affairs described above is like a fat pitch don the middle of home plate, just begging for thin-client computing proponents to smack it out of the park. When it comes to total cost of ownership for desktop computing services, thin-client computing is a bottom-line winner. Yes users will have to five up some control of their desktops. Any yes, administrators will need to learn a new approach to application deployment. But the payback is so clear; thin clients' arrival is almost inevitable.
The room is silent, making the faint click of a button reverberate around my bedroom. A short beep and the fans begin to whir. What happens next will determine my fate: back to the drawing board, or success in building my computer.
The motherboard is the main circuit board of a microcomputer. The motherboard contains the connectors for attaching additional boards. Typically, the motherboard contains the CPU, BIOS, memory, mass storage interfaces, serial and parallel ports, expansion slots, and all the controllers required to control standard peripheral devices, such as the display screen, keyboard, and disk drive. Collectively, all these chips that reside on the motherboard are known as the motherboard's chipset. On most PCs, it is possible to add memory chips directly to the motherboard. You may also be able to upgrade to a faster CP by replacing the CPU chip. To add additional core features, you may need to replace the motherboard entirely. (Glossary)
Today many people around the world rely on computers in their workplace, as well as their personal needs. Many people believe that computers are very complex machines that requires a person with a high level of expertise to put one together. Hence, most people spring to just buy one and do not think about that decision very deeply. In reality learning how to assemble a personal computer is not an extremely difficult one. Building a computer is much more cost effective, educates the builders about basic functions of a computer, and there is room for more expansion.
The next step is putting the computer together. First you will need to put the
I’ve always been very interested in computers, from the way that they function, to how reliant we are on them in the modern day. So when it came to narrowing down a list of potential topics for my senior project, building a computer was one of the top choices I had. Eventually I did choose to that. This included buying all of the separate parts and assembling it together. After that, I knew that I would have to install an operating system on it, most likely Microsoft Windows, for it to be functional to the common person. Most people do not know how to navigate through a computer without a GUI, also known as a graphical user interface. I felt that it would be a great learning experience to build my own computer system, and did prove to be in the end. I knew that the first step I would have to do was figure out how assemble all of the parts, along with find out which parts work with each other. Although it seems like a complex process to do, I now know how to totally disassemble virtually all modern computers and could tell you what purpose each of the parts serve, and how combined they function together seamlessly. A future career I may pursue due to this project is a Network Administrator. This would include maintaining a businesses network along with all of the computers connected to it. I would have to provide support to the end users when they have problems with their computers, and help keep the individuals computers safe from viruses and other harmful things that computers are susceptible to. I believe that I would be perfectly suited for a job similar to this. Overall, choosing this project was very eventful.
A processor is the chip inside a computer which carries out of the functions of the computer at various speeds. There are many processors on the market today. The two most well known companies that make processors are Intel and AMD. Intel produces the Pentium chip, with the most recent version of the Pentium chip being the Pentium 3. Intel also produces the Celeron processor (Intel processors). AMD produces the Athlon processor and the Duron processor (AMD presents).
CPU Stands for "Central Processing Unit." The CPU is the primary component of a computer that processes instructions. It runs the operating system and applications, constantly receiving input from the user or active software
Computer memory refers to any physical device that has the ability of storing information either permanently or temporarily. For instance, the Random Access Memory (RAM) is a volatile memory that has the ability of storing information on various integrated circuits that are used by not only the operating system, but also by the hardware and software. In essence, there are two major types of computer memory namely Read Only Memory (ROM) and the Random Access Memory (RAM). ROM refers to smallest parts of a computer system’s silicon or solid state memory which is not only fixed in size, but also permanently stores or keeps the instructions of the manufacturer upon switching on a computer. On the other hand, RM refers to the larger part of a computer memory that comprises of floppies, DVD, CD, and hard disk which are together referred to as secondary storage and which are employed or applied in both running of programs as well as archiving of relevant data. It is prudent to note that computer memory can either be volatile and non-volatile (Tanenbaum & Austin, 2012).
Computers are very complex and have many different uses. This makes for a very complex system of parts that work together to do what the user wants from the computer. The purpose of this paper is to explain a few main components of the computer. The components covered are going to be system units, Motherboards, Central Processing Units, and Memory. Many people are not familiar with these terms and their meaning. These components are commonly mistaken for one and other.
According to Parsons and Oja (2014), they state that a “microprocessor is an integrated circuit designed to process instructions” (p 67).
A CPU has various discrete units to help it in these tasks for example there is an arithmetic and logic unit(ALU) that takes care of all the math and logical data comparisons that need to performed. A control register makes sure everything happens in the right sequence. The motherboard is the main circuit board inside the PC. All other components are either slotted into or soldered to this board.
In designing a computer system, architects consider five major elements that make up the system's hardware: the arithmetic/logic unit, control unit, memory, input, and output. The arithmetic/logic unit performs arithmetic and compares numerical values. The control unit directs the operation of the computer by taking the user instructions and transforming them into electrical signals that the computer's circuitry can understand. The combination of the arithmetic/logic unit and the control unit is called the central processing unit (CPU). The memory stores instructions and data.
