The processing capability of a computer; how fast a computer can perform an operation
1 of 19
computer system
All the components that make up a complete, working computer, e.g. hardware, software, peripherals
2 of 19
handshake process
The process by which a sender on a network alerts a receiver of a coming message and the protocol that is going to be used, e.g. between a computer and printer to establish if it is ready to receive transmitted data
3 of 19
hub
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
4 of 19
IP address
An identifying address, unique to each computer, that is mapped to the NIC and allows computers to send messages and files across the network
5 of 19
LAN
A network that covers a relatively small, localized area, like an office or school
6 of 19
MAC address
A unique 12-digit hexadecimal number given to every device when it is manufactured
7 of 19
network
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
8 of 19
network interface card
A special device added to a computer that allows it to function as part of a network
9 of 19
peer to peer
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
10 of 19
packet
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
11 of 19
router
A device that enables multiple computers and devices to connect to the same network. Routers control priorities and rules such as connections and traffic.
12 of 19
scale
Describes the physical reach of a network, whether relatively small (LAN) or large (WAN)
13 of 19
server
A computer or program that ‘serves’ data to a client once it has been requested, e.g. web server, mail server
14 of 19
switch
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
15 of 19
thin client
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.
16 of 19
topology
Describes the arrangement of devices on a network, e.g. ring, bus, mesh
17 of 19
WAN
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.
18 of 19
wireless network card
Like a standard NIC, but without the use of wires, it has a transmitter/receiver for sending signals via radio waves
