How a Computer Works Introduction: A computer is a device which is used for several applications; business, gaming, or school. It’s important for people to know how computers work because in this day and age, operating a computer is an everyday task. This complex electrical device utilizes several parts inside of it to keep itself cool, conduct the proper tasks, and maintain stability. These devices can be found several places whether it be on the job, in one’s room, or on a school campus. Computers are essential for everyday use in order to complete what is required. What each component is and its function will be described. Components: A computer is a combination of several parts. These parts are Random Access Memory (RAM), a Central Processing …show more content…
RAM is used for memory caching, which means when the computer’s in operation, programs use this hardware for quick access and has memory saved temporarily for applications that’s deleted once the computer’s powered down. A CPU is what performs the large part of information processing in the computer, this tells what each part should be doing and it also proccesses requests; whether it be to turn on a cooling fan or to accept information to provide processing for words. It’s very important that the CPU is cooled well as it generates a lot of thermal energy. This heat is dissipated using a CPU cooler which often consists of a heatsink and fan. Newer technology is using liquid cooling and a radiator, which is a quiet solution to keep the CPU cool. The GPU is what processes graphics to create a display. Some graphics cards are powerful enough to provide viewing in multiple displays. A higher performance graphics card requires direct connection to the power supply as the motherboard can’t keep up with the power consumption of the card. Graphics cards can be combined to work together to process graphics. A cable linking
Processor (CPU) – The processor, also known as the Central Processing Unit runs the operating system and other applications. It is constantly receiving data from the user or other active software. The data is then processed and then an output is produced which either will be displayed on screen or stored by an application.
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
The Central Processing Unit (CPU) is the brains of the computer where most of the calculations take place and it is the most important element of a computer system. For the PC the CPU is housed in a chip (known as the microprocessor) such as the Inte...
A desktop computer consists of a computer system unit, a keyboard, a mouse, and a monitor. These are also input devices which are the devices used to input data in the computer or used to provide data and control signals to an information processing system. The computer system unit is the enclosure for all the other main interior components of a computer. The primary function of the computer system unit is to hold all the other components together and protect the sensitive electronic parts from the outside elements.
The most common type of computer is the personal computer, which is otherwise known as P.C., or the desktop computer. Computers contain countless electronic parts. These parts all contribute to processing, sorting, and receiving data. Usually, computers are linked to thousands of other computers and handheld devices via the World Wide Web or also known as the internet. It is estimated that about half of the jobs today use computers. Computers have changed the way we communicate and learn forever. You can communicate to other people using phones, laptops, tablets and PCs. You can do all of this through the internet or also known as the World Wide Web. Before modern communication we didn't know about things happening on the other side of the world for weeks or even months. But today we know what is happening all over the world in an
Imagine working on your English papers sitting comfortably on your couch in front of the TV, or working outside on a beautiful day. This dream could be a reality for those who purchase a notebook computer. Today's notebooks have just as much computing power as desktop models but are more compact, and with wireless internet access are now more portable than ever. This paper will give a brief history of notebook computers, explain how they work, and compare a couple models.
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
Conventionally, a computer consists of at least one processing element, typically a central processing unit and some form of memory. The processing element carries out arithmetic and logic operations, and a sequencing and control unit that can change the order of operations based on stored information. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved.
Thousands of years ago calculations were done using people’s fingers and pebbles that were found just lying around. Technology has transformed so much that today the most complicated computations are done within seconds. Human dependency on computers is increasing everyday. Just think how hard it would be to live a week without a computer. We owe the advancements of computers and other such electronic devices to the intelligence of men of the past.
Computers are one of the most popular kinds of electronic devices in the world today. Whether kid or adult, male or female, everyone wants to learn how to operate the computer. People use computers for different purposes such as typing papers, creating websites, making presentations, browsing on the internet, playing games, etc. In fact, many people are still confused about choosing what kind of computer they want to buy. In the world today, there are two types of computers: notebook/laptop and desktop. They both are actually very different in several ways. In this paper, I will compare the size, connectivity, power, and price of notebook and desktop computers. I can make these comparisons because I have both a notebook and a desktop computer in my apartment.
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.
There are four types of memory. These are the RAM, ROM, EEPROM and the Bootstrap loader. The RAM, also known as Random Access Memory, is the temporary space where the processor places the data while it is being used. This allows the computer to find the information that is being requested quickly without having to search the hard drive space. Once the information has been processed, and stored onto a permanent storage device, it is cleared out of the RAM. The RAM also houses the operating system while in
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.
You usually say that the computer has 2 types of components. The hardware and software. The big difference between these 2 are that, you can touch and react with
Also known as the CPU (Central Processing Unit) is essentially the brain of the computer system it is responsible for processing information and makes sure that other parts of the computer system are functioning properly. The processor is mostly known as the most complex part to any computer system, without it the computer system would not be able to operate and perform at all.
