A server room is a space in an organization that is dedicated to housing the computer server and major networking devices. It is a critical room for any organization that has computerized its operations since that is where its data and processes reside. The main component in the room is a computer server that stores,…
An ethernet port is a networking interface that is found in networking devices that allows computers and other devices to connect to a network using a cable. The port is a female part of the connection where the male jack (RJ45) goes to connect the device to a wired network. Ethernet ports are found on…
The difference between UEFI and the legacy boot is that UEFI is the latest technology that is more secure and user-friendly while legacy is an old less secure method. Unified Extensible Firmware Interface (UEFI) uses the GUID Partition Table (GPT) partition while the legacy BIOS Master Boot Record (MBR) partition structure. Allows devices using UEFI…
Computer ergonomics involves the designing of the working environment, devices, and computer system for a comfortable and safe working area. By designing computers and work environments in an ergonomically sound way, it is possible to reduce health-related issues such as carpal tunnel syndrome, vision syndrome, back pains, etc. The main benefit of following ergonomic guidelines…
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…
Firmware is a type of software that is embedded in the device that controls all its functions. It is stored on the ROM, EPROM, or flash memory within the device by the manufacturer. It is found in devices such as computers, routers, smartphones, cameras, smart homes, etc. The main function of firmware is to boot…
The main difference between cache and Random Access Memory (RAM) is cache has a smaller storage capacity and is faster than the main memory. While RAM stores data that is currently being executed cache stores the most frequently used instructions. The cache is within the CPU chip, unlike RAM which is a separate component on…
Overclocking is the process of increasing the CPU clock speed of a computer’s central processing unit (CPU) or graphics processing unit (GPU) beyond the manufacturer’s rated speed. This is done by adjusting settings in the computer’s BIOS or by using software tools. The goal is to make the computer run faster, which can be useful…
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…
