The personal computer or PC consists of a number of physical components that are otherwise called computer hardware.
Which hardware components in personal computer include: Central Processing Unit or CPU a host of outbound / outbound devices Two main types of memory Data storage devices
Processor Central Unit (CPU) – represents the part of the computer in which calculations are made and instructions are executed. In most cases, we only briefly call it a processor. The CPU is a silicon chip that is located inside the personal computer system unit. It works like a small fast calculator processing the cffi information into it and then generates and transports it to its output.
Peripheral Devices – are all those devices that can be added to your computer.
These peripheral devices may be inbound and outbound. To input PC information, you need an input device. Keyboard and mouse are two of the most commonly used devices for data entry. Computer systems can use different outbound devices, each of them converting data to readable form. Monitors and printers are two of the most common devices for data entry.
Memory – represents the components of the computer in which it is temporarily stored, the data to be processed. There are two main types of memory, they are:
Random Memory Memory – RAM Only For Memory. Reading – ROM
RAM is used for temporary storage of data. It contains all the new data since the last preservation of our work. RAM content changes constantly and it loses when turning off the computer. The content is permanent and protected during the production process at the plant. For example (ROMs contain data that serve the normal functioning of the computer with its startup.
Hard Drive. – Almost all computers have a hard drive. Once the computer has been processed with data processing, the result must be stored somewhere in, permanently. Solid disk, is the computer device in it, which stores the data in, the longest time frames. The cffi data, stored in the hard disk, remain there even when the computer is turned off.
Mobile data storage devices. – There is a number of mobile devices for storing it. data. This includes floppy drives or floppy disks, ZIP disks, CD-ROMs and magnetic tape tapes
Central Processor Unit – CPU
As we mentioned earlier with the term hardware, we mean all the physical components from which a personal computer is built. These components include the CPU and various peripheral components, such as input / output devices. Input devices serve to input data into, the computer processes and interprets these data while the outbound devices have a duty to display the data. scoring and forwarding data at its exit. The CPU is built from silicon and is usually called logical chip, because it is designed to perform logical and arithmetic operations. Basic CPU operations are collecting, subtracting, comparing two numbers, and shifting numbers from one space to another.
The speed with which the CPU processes the data is measured with Mega Hertz – MHz. The higher the number of MHz, the faster the CPU will be.
