CPU is the abbreviation for central processing unit. Sometimes referred to simply as the central processor, but more commonly called processor, the CPU is the brains of the computer where most calculations take place. In terms of computing power, the CPU is the most important element of a computer system.
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 PC by replacing the CPU chip. To add additional core features, you may need to replace the motherboard entirely.
RAM is an acronym for random access memory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is found in servers, PCs, tablets, smartphones and other devices, such as printers.
A type of video adapter that contains its own processor to boost performance levels. These processors are specialized for computing graphical transformations, so they achieve better results than the general-purpose CPU used by the computer. In addition, they free up the computer's CPU to execute other commands while the graphics card is handling graphics computations.
The popularity of graphical applications, and especially multimedia applications, has made graphics accelerators a common enhancement. Most mid-range to high-end systems have a graphics card.
Non-Volatile Memory Express, or NVMe, is a communications standard and protocol developed to fully utilize the speed of the PCIe bus for faster, more efficient storage hardware access.
NVMe was developed to be deployed in computer hardware systems with solid state drives (SSDs).
Mini-SATA, or mSATA, is a low-profile interface connector that enables more effective Serial ATA (SATA) integration in small form-factor drives roughly the size of a business card, such as solid state disks (SSDs). mSATA supports data transfer rates of 1.5 Gb/s and 3.0 Gb/s for high performance while enabling compact integration in a wide variety of applications for the hard drives and solid state drives (SSDs) used in ultraportable laptops, netbooks and similar mobile devices.
Hard disk drives (also called hard drives or disk drives) is the mechanism that reads and writes data on a hard disk. Hard disk drives (HDDs) for PCs generally have seek times of about 12 milliseconds or less. Many disk drives improve their performance through a technique called caching.
There are several interface standards for passing data between a hard disk and a computer. The most common is SATA or Serial ATA.
Abbreviated SSD, a solid state drive is a high-performance plug-and-play storage device that contains no moving parts. SSD components include either DRAM or EEPROM memory boards, a memory bus board, a CPU, and a battery card.
Because they contain their own CPUs to manage data storage, they are a lot faster (18MBps for SCSI-II and 35 MBps for UltraWide SCSI interfaces) than conventional rotating hard disks ; therefore, they produce highest possible I/O rates.
An optical drive is a type of computer disk drive that reads and writes data from optical disks through laser beaming technology.This type of drive allows a user to retrieve, edit and delete the content from optical disks such as CDs, DVDs and Blu-ray disks. Optical drives are among the most common computer components.An optical drive may also be known as an optical disk drive (ODD).
Also called a power supply unit or PSU, the component that supplies power to a computer. Most personal computers can be plugged into standard electrical outlets. The power supply then pulls the required amount of electricity and converts the AC current to DC current. It also regulates the voltage to eliminate spikes and surges common in most electrical systems. Not all power supplies, however, do an adequate voltage-regulation job, so a computer is always susceptible to large voltage fluctuations.
Power supplies are rated in terms of the number of watts they generate. The more powerful the computer, the more watts it can provide to components.
