Computer Science
- Computer components
- Processors
- GPU (Graphics
Processing Unit)
- A programmable logic chip, specialised for
display functions. A GPU renders images
animations or videos for the computer
screen, the more powerful the GPU the
more high deffiniton assets it can render

- CPU (Central
Processing Unit)
- the CPU is the brains of the computer where most
of the calculations take place, there are many
different types of CPU from single cores to quad
cores. the CPU is one of the most important parts
of the computer system
- the amount of tasks a PC can complete at once depends on the
amount of cores; for example a single core processor could run
maybe one or 2 programs at a time where only a few calculations
are being made, on the other hand if you were trying to play a Large
video game for example Battlefield 1 a quad core processor would
be a better fit because it can make 4 calculations at the same time
and this is good for CPU intensive tasks like gaming
- another key factor of a CPU is its clock
speed, the clock speed measures how fast
the proccessor exacutes instructions, the
higher the clock speed the better. clock
speed is measured in megahertz or
gigahertz,

- Mother Board
- the motherboard is
the back bone of all
computers and it
connects all other
components
- "a printed circuit board containing the
principal components of a computer or
other device, with connectors for other
circuit boards to be slotted into."

- Memory
- RAM(Random
Access Memory)
- RAM memory is the 2nd fastest type of memory that is stored,
when the computer looses power all RAM memory is wiped of
the computer, RAM is memory that is needed to run
programs fast so the computer does not need to go though
the entire hard drive searching for one file.

- Hard memory
- hard memory is memory where the
main files of the computer are stored,
for example files like the operating
system and files the user saves to the
computer. hard memory is stored on
the hard drive for example. devices like
the hard drive and memory sticks can
store a huge amount of memory, the
typical hard drive is around 1TB in size.

- Power Suply
- A power supply is an electronic device
that supplies electric energy to an
electrical load. The primary function of a
power supply is to convert one form of
electrical energy to another. As a result,
power supplies are sometimes referred
to as electric power converters.
- the power supply sipplies
energy to the entire PC and all
USB devices and screens
connected to it

- software development life cycle
- types of life cycle
- waterfall
- requirements
- design
- implementation
- testing
- deployment
- maintenance
- There are some issues which come up in the client
environment. To fix those issues, patches are released.
Also to enhance the product some better versions are
released. Maintenance is done to deliver these changes in
the customer environment.

- Once the functional and
non-functional testing is done;
the product is deployed in the
customer environment or
released into the market.
- maintenance
- All the units developed in
the implementation phase
are integrated into a
system after testing of
each unit. Post integration
the entire system is tested
for any faults and failures.
- deployment
- With inputs from the system design, the system is first developed in small programs called units,
which are integrated in the next phase. Each unit is developed and tested for its functionality,
which is referred to as Unit Testing.
- testing
- The requirement specifications
from first phase are studied in this
phase and the system design is
prepared. This system design helps
in specifying hardware and system
requirements and helps in defining
the overall system architecture.
- implementation
- All possible requirements of
the system to be developed are
captured in this phase and
documented in a requirement
specification document.
- design
- All these phases are cascaded to each
other in which progress is seen as flowing
steadily downwards (like a waterfall)
through the phases. The next phase is
started only after the defined set of goals
are achieved for previous phase and it is
signed off, so the name "Waterfall Model".
In this model, phases do not overlap.
- requirements
- spiral
- the spiral model will go
infinately until the
software developer stops
it
- used for expensive projects
like AAA games ect
- it can be very expensive and
sometimes cost more than the
sofware makes
- it can go for a very long time for
example some games take so long to
make in the end they never actually get
released
- used with large companies with
very large teams
