A system clock or timer uses a quartz crystal oscillator to generate pulses. These pulses are counted as the number of cycles per second. Then the cycles are counted into Hertz. A modern computer has a million (MHz)or billion hertz per second(GHz). A 3.2GHz processor means it has 3.2 billion cycles per second. System clock…
Hyperthreading is an Intel-developed technology that allows a single physical central processing unit (CPU) to appear as two logical CPUs in the operating system and applications. If a system has 2 cores when hyperthreading is implemented it creates 2 more virtual cores. This means physically we have 2 cores but from an operating system point…
A chipset is a group of electronic microchip components in a computer or device that manages the data flow between the processor, memory, and other peripherals. It is a crucial component of a computer that manages data flow from the processor to the main memory and all other input-output devices. It acts as the central…
A mousepad is a simple, yet essential accessory for any computer user. It provides a smooth and stable surface for a computer mouse to glide over, improving the accuracy and precision of cursor movement. Whether you’re a gamer, a designer, or simply use a computer for work or leisure, a mousepad can make a big…
An uninterruptible power supply (UPS) is a device that provides a backup power source to critical devices and systems in the event of a power outage or other electrical disturbance. It is designed to keep these devices and systems running smoothly and uninterrupted, even in the case of a power failure. A computer is one…
Networking twisted pair (TP) cables are types of cables that come in pairs that are twisted. The twisting is used to reduce crosstalk and electromagnetic interference. They are the most common types of ethernet, CCTV, and telephone networking cable. They are simple to configure and cheaper compared to other types of guided networking media. Twisted…
In this digital age, information can be presented as either a soft copy or a hard copy. Hard copies are tangible physical documents while soft copies are intangible documents. Information presented as a soft copy is usually stored on computer storage devices and can be viewed from digital device screens. Hard copy information is presented…
A network interface card also known as a network controller or network adapter is a circuit board card fixed on a computer motherboard that enables connection to the network. Without a network card, either ethernet or wireless, a computer cannot connect to the internet. It acts as a physical connection (link/interface) between the computer &…
Many users use the term computer repair and maintenance interchangeably but they differ depending on when and how they are done. Computer repair is restoring a partial or total fault computer back to functionality while maintenance is the activities that are carried out to the device to reduce device breakdown. The main difference between computer…
Currently, we live in the information age that is characterized by high-speed data processing and other modern technologies. As some of these technologies continue to be used we realize better and new ways to use them for human benefits. This leads to better technologies that will be common in the future. Information age technologies have…
