Hardware and software determine a computer’s speed. The CPU is the main processor, but other components like RAM and hard drives also affect speed. Installed software can slow down a computer, so managing processes can free up resources. With the exception of the central processing unit (CPU), most hardware inside a computer has two numbers […]
Computer chips are thin wafers containing circuitry that drive modern devices. CPUs are the backbone of most computer systems, GPUs output data to monitors, RAM temporarily stores data, and custom chips drive many electronic devices. Computer chips are thin semiconductor wafers containing the circuitry that drives most modern computer devices. These chips can range in […]
External hard drives are a popular option for increased storage space and information security. They can be easily connected to a computer, reducing the risk of data loss or corruption. To transfer data, select an external hard drive that meets your storage needs, plug it into the computer, and select the files you want to […]
Computer processing is the execution of instructions by a CPU, which performs mathematical and logical operations through binary electrical states. The four stages of processing are fetch, decrypt, execute, and writeback. Processing cycles increase in speed with advanced technology, with one gigahertz cycle equaling 1 billion instructions per second. Computer processing is an action or […]
Computer software tells a computer what to do, with two main types: system and application. Hardware is tangible and does physical work, while software tells hardware what to do. Open source software can be modified, proprietary cannot. Programming quality is comparable, but open source may have faster bug fixes. Computer software is a program that […]
