Information Technology (IT)
Is the use of digital technology, like computers and the internet, to store and process data into
useful information
What does an I.T specialist do day-to-day?
Confirms that an organization technological equipment is running
Data
Computer data is information processed or stored by a computer.
What is a computer?
A device that stores and processes data by performing calculations
What cards had holes in them that were historically used to store data?
Punch Cards
What is cryptography
The art of writing and solving code
What is magnetic tape?
An older secondary storage medium that uses a strip of thin plastic coated with a magnetically
sensitive recording medium
What is software called when it can be freely distributed, modified, and shared?
Open source
Binary System
,A system in which numbers and values are represented using only the digits 0 and 1.
Bits
The smallest unit of data the computer can process
Bytes
8 bits
Character Encoding
Assigns our binary values to characters, so that we as humans can read them
Abstraction
A simplified representation of something more complex.
Hardware
The physical components of a computer.
- Motherboard
- CPU
- RAM/ROM
- Power Drive.
- HDD/SSD
Software
The programs and other operating information are used by a computer.
Operating system
The software that supports a computer's basic functions, such as scheduling tasks, executing
applications, and controlling peripherals.
- MS Windows
- macOS
- Linux
Software Layer
How we, as users, directly interact with our computers
Ports
Plug sockets that enable you to connect an external device.
Central Processing Unit (CPU)
, The brain of the computer that performs instructions defined by software; processing all of your
commands and actions. As more tasks are completed by the CPU, more heat will be
produced by it, so this means that your CPU needs to be cooled appropriately.
Random Access Memory (RAM)
Computer location where instructions and data are stored on a temporary basis. Responsible
for storing the data from the apps and programs you open. This memory is volatile.
Hard Drive
The primary storage component of a computer holds all software and data. Can be used to store
lower amounts of data than other digital storage media such as flash drive
Motherboard
A motherboard is the central part of a computer. All of the computer components are
connected to the motherboard. The motherboard has many jobs, including controlling power to
all the parts, managing data flow between parts, and organizing communication between the
CPU and other parts of the machine.
Power Supply
Converts AC power from the wall outlet into the lower voltages of DC power required to power
all components of the computer such as the CPU, RAM, and motherboard.
Programs
Sets of instructions that carry out the tasks of the user.
Land Grid Array (LGA)
A feature of a CPU socket whereby pads, called lands, are used to make contact in uniform rows
over the socket.
Pin grid array (PGA)
A feature of a CPU socket whereby the pins are aligned in uniform rows around the socket.
Heat Sink
A device or substance for absorbing excessive or unwanted heat.
RAM Information
When the machine is powered off the RAM is usually wiped and to run a program it needs to be
stored in RAM for computers to process it
