In digital electronics, the logic gates are the basic building blocks of all digital circuits that act as the switching devices and determine whether the input signal may pass through to the output of the digital circuits. As the name implies, a logic gate is a digital circuit used to ... Read More

Both hardware storage and cloud are storage models used to store data in a digital form. In both cases, the digital data is stored in storage servers. The most basic difference between hardware and cloud is in data accessibility. In hardware, data can be accessed only on the system in ... Read More

The most basic difference between hardware and computer platform is that the hardware is the physical components of a computer system that can be seen, touched, and manipulate, whereas a computer platform is a fundamental hardware and software infrastructure which supports the operation of computer applications.

Hard drives and flash drives are the two major types of storage devices used in computer systems for permanent data storage. The most basic difference between these two storage devices is that a hard drive is an electromechanical storage device having some movable parts, whereas a flash drive is an ... Read More

In computers, different types of disks are used to store data and information. The two most popular types of disks are hard disk and floppy disk. Both hard disk and floppy disk are the type of secondary storage devices used to store permanent data and information. The primary difference between ... Read More

There are two different technologies namely, CVT (Constant Voltage Transformer) and UPS (Uninterrupted Power Supply) that are used for providing power conditioning and protection. A CVT is an electrical device used to provide a constant output voltage despite variations in the input voltage or load, whereas a UPS is an ... Read More

A computer is a general purpose electronic device that is used to perform a wide range of computing tasks, whereas an embedded system is a specialized computer that is used to perform one or more specific functions. Read this article to learn how a computer is different from an ... Read More

Both CD-R and CD-RW are types of optical storage devices. A CD-R (Compact Disk- Recordable) is a write-once read-many device, which means data can be written to it only once but can be read many times. In contrast, a CD-RW (Compact Disk-Rewritable) is a CD that allows data to be ... Read More

In a computer system, power supply or power supply unit is a hardware component that supplies required electrical power to other components of the computer system. The power supply unit converts a 220 V AC (Alternating Current) supply into a low voltage DC (Direct Current) supply. The major function that ... Read More
