A computer is an electronic device that stores, retrieves, and processes data, and can be programmed with instructions. A computer is composed of hardware and software, and can exist in a variety of sizes and configurations. Hardware is the physical equipment of a computer system, including the central processing unit (CPU), data-storage devices, terminals, printer, etc. Software is a program or set of instructions or rules that control the operation of a computer. The most obvious hardware component is the computer case. The case is where size comes into play. A bigger case allows more room for components. A bigger case is most often used for servers. For basic home computing needs, a small or mid-sized case is most common. Cases also …show more content…
It is responsible for reading the instructions and data from the main memory in order to perform calculations and coordinate the other components. It interprets instructions and processes data contained in computer programs. The actual CPU is about 1.5 inches square. Today, some of the more widely used CPU’s are made by Intel and known as Pentium 1 through Pentium 4. This information and instructions for the CPU are stored in Random Access Memory (RAM). This memory is the next hardware component for a bare bones PC referred to as the main memory. The CPU has direct access to any instructions for programs to be executed that are in the main memory and only in the main memory. The main memory is volatile which means it can only store data or instructions when the computer is powered on. The device that stores data when the PC is powered off is the hard drive. It is the computers primary method of storage. Another way it stores memory is through the floppy drive. This form of memory is removable. In order to store something in the main memory, it must first be input through the keyboard or mouse or other input device. A keyboard is designed to enter text, numbers, or punctuation. It is the main input device on most PC’s. The mouse is a pointing device used to select, point, and click on a computer screen. The keyboard and mouse are used to send information to the CPU. This information is translated through other devices called output devices such as the monitor. This
CPU : This is the central processing unit, better known as the processor. This is the heart of the PC where calculations are madeRAM: RAM stands for random access memory. This part in the PC grabs the file from the hard drive and stores on its non permanent memory so that you can have multiple windows open such as word and be able to access this data faster. The more RAM the faster and more apps you can open and the bigger the files the ram can hold. However, if you are using word and your pc crashes and you haven’t saved the file to the hard drive. The work that you have done will be lost due to that RAM does not hold on to files. GPU(Graphics card): The graphics
RAM (Random Accesses Memory): RAM is used by CPU when a computer is running to store the information that it needs to be used very quickly but it does not store any information permanently.
Motherboard is centralized computer of the PC that all framework inside the electronic in light of the fact that a few sections are not quite the same as each other like RAM, CPU and framework unit
Answer: hardware and software is the core of the computer without it computer cannot perform its task. The PC contains various electronic components that we are able to see when we open it. By only pc by itself cannot perform their task on their own. Our PC needs something to get instructed to set it on where we need software to perform it. There are six different component of hardware to function the computer .The first one is central processing unit(CPU )it is the brain of the
It executes instructions. The major companies that produce microprocessor for IBM and Macintosh computers are Motorola and Intel. Microprocessor requires a primary storage, a system clock and power supply to function as processor. Some families of microprocessor chips are used by quite a lot of types of PCs. The internal components of a standard microprocessor are Arithmetic logic Unit (ALU), Control Unit (CU), cache memory, internal buses and registers. The basic characteristics of a microprocessor are clock speed, instruction set and bandwidth. [Source: (Mcqsetscom,
The final major component you’ll need is the power supply. This does just as the name implies, it powers the computer. Depending on what you plan on using the computer for will determine the “size” of power supply you’ll need. Just as I said with picking the case, wait to pick this out until you figure out how much power you’ll need.
Are you tired of paying hundreds or thousands of dollars to a company for a computer that gives a below average experience? Well, why not build your own computer? This might sound like a crazy idea, but once you understand the principles, it's a piece of cake and you will probably end up saving 100 or 200 dollars from buying the same thing from a well-known company. You might be asking yourself, "How on earth am I supposed to build a computer? Where will I obtain the parts?". Well, don't worry, because this guide is everything you need from sourcing the parts to booting up your own functional computer. The basics are always the computer essentials: a motherboard, a CPU, a graphics card [optional], RAM, a hard drive, a power supply and a
Primary storage (or main memory or internal memory), often referred to simply as memory, is the only one directly accessible to the CPU. The CPU continuously reads instructions stored there and executes them as required. Any data actively operated on is also stored there in uniform manner.
The most fundamental characteristic of an SoC is complexity. A memory chip may have many transistors, but its regular structure makes it a component and not a system. Exactly what components are assembled on the SoC varies with the application. Many SoCs contain analog and mixed-signal circuitry for input/output (I/O). Although some high-performance I/O applications require a separate analog interface chip that serves as a companion to a digital SoC, most of an SoC is digital because that is the only way to build such complex functions reliably. The system may contain memory, instruction-set processors (central processing units [CPUs]), specialized logic, busses, and other digital functions. The architecture of the system is generally tailored to the application rather than being a
A Computer is an electronic device, operating under the control of instructions stored in its own memory
The computer is designed around the Arduino MEGA2560 microprocessor. The basic components consist of buffers, decoder, RAM, ROM, and I/O ports. The diagram is shown in Figure 2.5.
The CPU or central processing unit is responsible for reading and completing or delivering commands from the hardware and the software. It is said by many people to be the brain of the computer. Integrated CPUs can have multiple cores or multiple processors on a single chip, these are multi-core processors and have more power than a normal processor as it is able to do multiple tasks at the same time.
Computer memory (an information storage device, a storage device) is a part of a computer, a physical device or a data storage medium used in calculations for a particular time. Memory, like the CPU, is an unchanged part of the computer since the 1940s. Memory in computing devices has a hierarchical structure and usually involves the use of multiple memory devices having different characteristics.
What is computer? Does everyone know what computer is? What is its function? Computer is the most probably used technology in our generation which is 21st century. But does anyone know what are computer and its function in our society? According to Margaret Rouse (2005), she said that a computer is a device that accepts information (in the form of digitalized data) and manipulates it for some result based on a program or sequence of instructions on how the data is to be processed. Complex computers also include the means for storing data (including the program, which is also a form of data) for some necessary duration. A program may be invariable and built into the computer (and called logic circuitry as it is on microprocessors) or different programs may be provided to
A computer has basic information that must be understood. A computer is a device that can manipulate information or data. Computers can be a laptop, a tablet, a mobile phone, a server, and your everyday desktop computer. On a computer you can stream movies, create documents, browse the web, or send emails. To do these things on a computer hardware and software is needed.
