Processors
The speed at which the processor operates internally, usually expressed in GHz.
What is processor frequency?
RAM chips that retain information without the need for refreshing, as long as the computer’s power is on; more expensive than traditional DRAM.
What is static RAM (SRAM)?
Port 80
What is HTTP (Hypertext Transfer Protocol)?
A small network consisting of personal devices at close range; the devices can include smartphones, PDAs, and notebook computers.
What is a PAN (personal area network)?
A network device that has firmware that can be configured to monitor, manage, and prioritize network traffic.
What is a managed switch?
Two processing units installed within a sing processor; first used by the Pentium processor.
What is multiprocessing?
A type of memory technology used on DIMMs that runs at twice the speed of the system clock, has one notch, and uses 184 pins.
What is DDR (Double Data Rate)?
Port 25
What is SMTP (Simple Mail Transfer Protocol)?
A network or group of networks that span a large geographical area.
What is a Wide Area Network (WAN)?
Cabling, such as a network cable, that uses pairs of wires twisted together to reduce crosstalk.
What is Twisted-pair cabling?
A system that contains more than one processor. The motherboard has more than one processor socket, and the processors must be rated to work in this multiprocessor environment.
What is a multiprocessor platform?
The most common type of system memory; it requires refreshing every few milliseconds.
What is dynamic RAM (DRAM)?
Port 110
What is POP3 (Post Office Protocol, version 3)?
A type of LAN that does not use wires or cables to create connections but instead transmits data over radio or infrared waves.
What is a WLAN (wireless local area network)?
A popular rating used for UTP cables and rated for Fast Ethernet and Gigabit Ethernet.
What is CAT-5e?
A processor technology whereby the processor housing contains two or more processor cores that operate at the same frequency but independently of each other.
What is multicore processing?
A chipset feature on a motherboard that checks the integrity of data stored on DIMMs or RIMMs and can correct single-bit errors in a byte.
What is ECC (error-correcting code)?
Port 53
What is the Domain Name System (DNS)?
An outdated Wi-Fi standard that transmitted up to 11Mbps and experienced interference from cordless phones and microwaves.
What is 802.11b?
A feature that might be available on high-end wired network adapters that allows 15.4 watts of power to be transmitted over Ethernet cable to remote devices.
What is Power over Ethernet (PoE)?
The Intel technology that allows each logical processor within the processor package to handle an individual thread in parallel; other threads are handled by other processors within the package
What is Hyper-Threading?
A method whereby the OS uses the hard drive as though it were RAM.
What is Virtual RAM or Virtual Memory?
The client receives data on Port 20 and the server listens at port 21.
What is the File Transfer Protocol (FTP)?
A broadband technology that uses cable TV lines and is always connected (always up).
What is Cable Internet?
The network of devices, such as cameras, refrigerators, and locks, that have an IP address and can connect to the local network and are accessible from the Internet.
What is the Internet of Things (IoT)?
