Also, I have bought several USB 16GB flash drives. And I have an HP Envy printer that I
use to print off assignment details, to have them near me while completing each
assignment to make sure I do not forget anything.

Network Connection and Security
I have fiber optic high-speed, broadband internet through my electric company, Empower.
I use McAfee security for both laptops and my smartphone. I have 5 devices/ 2-year
subscription. It includes secure VPN (Virtual Private Network), Antivirus, Identity
Protection Service, Home Network Security, Safe Web Browsing, Password Manager, and
McAfee® Shredder™. I am extremely bad at using the same password for everything, I
think if I used different passwords for my accounts, it would increase my security. Also,
increasing the physical security of my laptops would be beneficial.

Hardware and Software
Hardware
Hardware is the physical components of a computer. Examples of this would be the CPU,
Monitor, Keyboard, and Memory Devices. Hardware has four main categories: input
devices, output devices, storage, and internal components. The keyboard, monitor, and
speakers are considered input and output devices. When you type something on the
keyboard, a switch beneath the key closes, which allows current to flow into a small chip
in a keyboard. Every key has a scan code number, which indicates to its spot on the
keyboard. Then, the keyboard outputs this number as binary data to the computer’s CPU.
Software
Software is the instructions that tell a computer what to do. Some types of software are
system software, embedded software, development tools, and application software. System
software controls the internal functions of a computer. A few examples of this are the
operating system which controls what comes on the monitor. Application software directs
the computer to execute commands given by the user and may be said to include any
program that processes data for a user. Application software can include word processors,
spreadsheets, database management, inventory, and payroll programs. Embedded
software is used to create the software used to control machines and devices, such as
automobiles, phones, and robots. Development tools that software developers use to do
their job, including code editors, linkers, and debuggers. Each category requires different
types of software developers. Software is developed using computer programming, carried
out by a software developer. The end-to-end process is sometimes referred to as the
software development life cycle (SDLC). When you input information into a computer, all
the computer understands is binary language (0’s and 1’s). The computer translates the
binary language into information you work with on a computer such as decimals numbers,
text, photos, sound, and video. Computers take input from their users, stores, and
processes them as information, and finally provides their users with outputs of various
kinds.
Relationship between hardware and software
Without hardware, the software cannot be used. Hardware without a set of instructions is
useless. One without the other, cannot run independently. Both work together to produce
output. A computer’s operating system is what allows the software and hardware to
communicate. For the operating system to communicate with the hardware, it needs
drivers. Drivers show the operating system how to interact with each bit of hardware. The
operating system also works directly with the CPU. Together they create a checklist of
processes to execute and makes sure each task gets done.
