The document provides definitions and explanations for various computer networking and repair terms. It starts with logic gates, which are fundamental components in digital circuits, characterized by binary conditions.
Soft Soldering
Soft soldering is the joining of small intricate parts that have low melting points.
Ransomware
Ransomware is software designed to block access to a computer system until a sum of money is paid.
Spyware
Spyware is software that gives users the ability to obtain information about another user’s computer activities and to collect personal information or monitor internet browsing activities.
. Antimalware
Antimalware is software that protects a computer from infections that are aimed at stealing data from the user or computer.
Trojan Horses
Trojan Horses are programs designed to breach the security of a computer system typically to allow hackers to gain access to a user’s system.
Disk Cleanups
Disk cleanups are designed to free up disk space on a computer’s hard drive.
. Disaster Recovery Plan
A disaster recovery plan, or DRP, is a process to recover and protect a business’s IT infrastructure in the event of a disaster.
System Maintenance
System maintenance involves the modification of a system to correct faults, improve performance, and/or adapt the system to a different environment
Floppy Disk Drive
A floppy disk drive, or FDD, is a thin and flexible magnetic storage enclosure that stores data externally for electronic devices.
Hard Disk Drives
Hard disk drives are data storage devices that use magnetic storage to store and retrieve digital information. Both internal and external hard drives are available.
eSATA
A Serial Advanced Technology Attachment, or eSATA, provides a signal connection for external storage devices that use the computer for power.
USB
USB stands for Universal Serial Bus. It is used to connect a computer to devices and peripherals.
S-Video
A standard definition video connection, or S-Video, separates black-and-white and color signals from the computer to a monitor.
. Peripherals
Peripherals are devices used to input or output data to and from the user and an electronic device. The most widely used peripheral devices include mice, keyboards, monitors, and printers.
RAM
Random Access Memory, or RAM, is the term given to computer data storage used to store frequently accessed data to increase the speed of the system.
. Power Supply
The power supply converts main AC current to low-voltage regulated DC current used to power an electronic device.
Microprocessor
A microprocessor is a central processing unit, or CPU, contained on a single integrated circuit.
Motherboard
A motherboard is a printed circuit board containing the components of an electronic device.
. Memory
Memory is a temporary storage area that holds data and instructions for an electronic device to function.
Logic Gates
Most logic gates have two inputs and one output. Every terminal is in one of the two binary conditions, 0 or 1.
Hard Soldering
Hard soldering is the connection of two pieces of metal at a high temperature.
TCP/IP
Transmission Control Protocol/Internet Protocol, or TCP/IP, is a set of networking protocols allowing multiple computers to communicate.
. Wi-Fi
Wireless fidelity, or Wi-Fi, is wireless local area networking for computers or devices that connect to the internet via a wireless access point (WLAN).
LANs
Local area networks, or LANs, are computers that are close enough to connect usually in the same building.
. HDMI
High-Definition Multimedia Interface, or HDMI, is used to transmit data between components, typically an electronic device and monitor or television.
