A fax machine also known as a facsimile, telecopying, or telefax, is a device that scans text and images and transmits over the telephone line to another similar device. Fax machines work by scanning a document and converting it into a digital format, which is then transmitted to the receiving fax machine. The receiving fax…
Serial Advanced Technology Attachment (Serial ATA) is a standard of cables and connectors that are used to connect storage devices such as hard disks to the computer motherboard. SATA cables are used to transfer data and power to the device. There are 2 main SATA cables, data, and power cables. The data cable connects to…
Cache memory also known as CPU memory is a high-speed intelligent memory buffer that temporarily stores data the processor needs. This allows the computer processor to execute instructions faster. Cache reduces retrieval time compared to if data was accessed directly from the main memory (RAM). It is said to be intelligent since it not only…
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…
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…
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 &…
Floppy disks also known as diskettes are the old type of magnetic storage devices that were used in earlier computers. The initial floppy disk was just a disk without a cover. It was later covered to secure it in a floppy casing. Today’s computers don’t come with floppy drives but we have external drives connected…
