abstraction (process) – the act of selecting and
capturing relevant information about a thing,
a system or a problem.

used to create web pages.
input (noun) – an input is a data value passed
from the outside world to a computer.
input (verb) – to input is to send data from the
outside world into a computer system.
internet – a network of interconnected networks.
interpreter – a program that converts instructions
written in one language into equivalent
instructions in another language, and executes

numeric value that is assigned to a computer or
other device connected to the internet so that it
may be identified and located.
lists – a data structure for storing ordered values.
model – a representation of (some part of) a
problem or a system.
modelling – the act of creating a model.
modular design – the practice of designing a
system or program as a set of independent
but interacting units (modules) that may be
implemented and tested separately before
bringing them together to solve the overall
problem.
network – more precisely, a computer network;
a collection of computational devices (personal
computers, phones, servers, switches, routers,
and so on) connected to one another by cables
or by wireless media, and arranged so that data
may be sent between devices either directly or via
other devices.
operating system – a set of programs that manage
the functioning of, and other programs’ access to,
hardware.
output (noun) – a response from a system.
output (verb) – to generate an output.
packet – more precisely, a network packet. A
formatted unit of data for transmission across a
network. Each packet contains part of a message
plus some additional data, including where it is
from and where it is going.
pixel – the smallest controllable element of
picture/display.
process (noun) – a process is a running program.
process (verb) – the act of using data to perform a
calculation or other operation.

and designing, writing, testing and maintaining
programs to solve them.

give a computer instructions.
repetition – the process of repeating a task a set
number of times or until a condition is met.
resolution – a measurement of the number of
pixels needed to display an image.
router – more precisely, a network router. A
router is a device that connects networks to one
another (typically one or more local area networks
(LANs) to a wide area network (WAN)), and directs
packets between networks. A home broadband
router performs the functions of a switch while
allowing computers to connect to the internet.
selection – using conditions to control the flow of
a program.
sequence (noun) – an ordered set of instructions.
sequence (verb) – to arrange a set of instructions
in a particular order.
server – a computer or program dedicated to a
particular set of tasks that provides services to
other computers or programs on a network.
software – the programs that run on the
hardware/computer system.
switch – more precisely, a network switch. This is
a device that connects multiple computers to one
another on a single local area network (LAN), and
directs packets from machine to machine.

under column headings.
