The processing capability of a computer; how fast a computer can perform an operation
Computer power
1 of 18
All the components that make up a complete, working computer, e.g. hardware, software, peripherals
computer system
2 of 18
A connection device that works at a device level, it connects multiple computers (via the NICs) together on a network and allows them all to share transmitted data
hub
3 of 18
An identifying address, unique to each computer, that is mapped to the NIC and allows computers to send messages and files across the network
IP address
4 of 18
A network that covers a relatively small, localized area, like an office or school
local area network
5 of 18
A unique 12-digit hexadecimal number given to every device when it is manufactured
media access control (MAC) address
6 of 18
A linked collection of computer systems that allows resources and computer power to be shared, e.g. a computer network at a school or college
network
7 of 18
A special device added to a computer that allows it to function as part of a network
network interface card (NIC)
8 of 18
A small collection of broken down data, sent by computers across a network, that finds the quickest route to its destination and is then reassembled at the other side
packet
9 of 18
A network that links computers directly allowing users to access programs and resources on each other’s hard drives. A P2P network does not require a server
peer to peer (P2P)
10 of 18
A device that enables multiple computers and devices to connect to the same network. Routers control priorities and rules such as connections and traffic.
router
11 of 18
Describes the physical reach of a network, whether relatively small (LAN) or large (WAN)
scale
12 of 18
A computer or program that ‘serves’ data to a client once it has been requested, e.g. web server, mail server
server
13 of 18
A connection device that connects multiple computers to a network and (unlike a hub) allows data to be transmitted to specified computers, which frees up bandwidth and improves speed and performance
switch
14 of 18
A computer device that connects to a network and allows interaction with programs on the server. It uses the power residing on the server without downloading or saving any data to the device itself.
thin client
15 of 18
Describes the arrangement of devices on a network, e.g. ring, bus, mesh
topology
16 of 18
A network that covers a large geographical area and connects different buildings, sites, even countries. The internet is an example of a global WAN. Two or more LANs make a WAN.
wide area network (WAN)
17 of 18
Like a standard NIC, but without the use of wires, it has a transmitter/receiver for sending signals via radio waves
