every company regardless of size relies on this
Hardware - correct answer physical devices associated with a computer system
physical phone itself
software - correct answer set of instructions the hardware executes to carry out
specific tasks
anything telling the computer what to do, web browsers, photos, games
operating system and apps
video - correct answer two key concepts foundational to technology
binary: series of 1's and 0's. 8 of these create one byte. one byte creates a single
character: binary is the only language computers only understanding
-computing and networking wouldn't work without it
Moore's law: cost of computing and data communications and storage and essentially 0.
allowed us to have power and create more powerful instruments for less and less
money
video on hardware - correct answer hardware:
-clients: end user device (smartphones, tablets, laptops)
-server: computer dedicated to providing info in response to requests
--servers stored in specially designed data centers
,3 basic hardware components
- HDD (hard disk drive): where storage is (photos, documents)
- RAM (random access memory): temp kind of memory where applications can be
called into it for faster access
- CPU (central processing unit): brain of device; processing requests (ultra-fast)
most hardware and software run via network - correct answer
network - correct answer communications systems created by linking two or more
devices and establishing a standard methodology in which they communicate
most companies use a specific form of network infrastructure called client and server
network
client - correct answer computer designed to request info from a server

website (server responding with the web page being requested by client)

failures or system crashes as the backup system immediately and automatically takes
over with no loss of service
example: enables business to support operations if there is a power failure or flood
EXPENSIVE FORM OF BACK UP
only mission critical applications use it
failover - correct answer a specific type of fault tolerance, occurs when a redundant
storage server offers an exact replica of the real-time data, and if the primary server
crashes, the users are automatically directed to the secondary server or backup server
high speed and cost method of back up and recovery
failback - correct answer occurs when the primary machine recovers and resumes
operations, taking over from the secondary server
disaster recovery plan - correct answer a detailed process for recovering information
or a system in the event of a catastrophic disaster
to combat these disasters below they create this
foresees possibility that not only computer equipment but also buildings may be
