Students will be able to demonstrate their understanding of basic operating system installation by installing and configuring a common desktop operating system so that they can prepare common desktop PCs for deployment.
This week we will be working in the lab with Operating Systems installation. We will be wiping and repartitioning the hard drives of our lab PCs, performing a basic operating system installation (Windows 10), and installing a specialized OS (Kali Linux) that we will use in the second half of our course.
Collect your PC from the storage shelf and assemble it on the tables in Lab 212. Connect all peripherals and test it to ensure that it still boots to the desktop login window. You do not need to log in.
Windows 10 installation media will be distributed. Boot from the Windows installation USB to begin the installation process.
You will be directed in class how to partition and format your hard drive. Once the hard drive is formatted to a single active partition, you may proceed with the installation process.
Follow the installation process, paying close attention to all instructions and prompts.
The required Account Name, Password and Machine Name naming convention will be written on the whiteboard in front of the room. Please make sure you type the Account Name and Password correctly, using capitals where indicated. Also, please take care to follow the correct Machine Name convention. DO NOT MAKE UP YOUR OWN INFORMATION FOR THESE STEPS.
Your Windows 10 installation is nearly complete when your machine boots to the desktop, and you have successfully logged into the Admin account. You should then browse to the Dell Support page, where you will download and install all required support updates for your PC. Use the Dell support tag located on the top of the machine to determine your required updates on the Dell Support site. See me if your Dell support tag is missing.
Once all device drivers and support software installations are complete, use the Control Panel to access the Windows Update settings. Click the Check for Updates button to search for updates and service packs. Install all service packs and updates that are available.
Your Windows 10 installation is complete when all required device drivers, service packs and system updates are complete. Next week, we will install a specialized OS called Kali Linux, that is specifically designed for offensive security and penetration testing

Decimal System A numbering system that uses ten digits, 0 through 9.
Binary System A numbering system that uses two digits, 0 and 1.
Hexadecimal System A numbering system that uses sixteen digits, 0 through 9, and A through F.
Bit The smallest unit of digital information, represented by a 1 or 0.
Byte A group of eight bits joined together. Digital Data A physical signal, such as text, numbers, graphics, or sound, interpreted by converting it into binary numbers.
Encoded Integers The representation of integers using a group of bytes. Normally, one bit in one of the byes represents the sign, 1 for negative and 0 for positive. The remaining 31 bits are used to encode the number itself using binary digits.
Encoded Text The representation of text by assigning a unique binary code to each character.
Processor Speed The speed at which a computer processes information, as measured by the number of cycles per second (Hertz) that the computer’s CPU operates at. Processor speed is measured in kilohertz, megahertz, and gigahertz.
Storage Space The measurement in bytes of the volume that a storage device can contain. Storage space is measured in kilobytes (1024 bytes), megabytes (1024 kilobytes), gigabytes (1024 megabytes), and terabytes (1024 gigabytes).
Throughput The measurement in bits per second that information is transferred through a network from one computer to another. Throughput is measured in Kbps (kilobits per second), Mbps (megabits per second), and Gbps (gigabits per second).
ASCII Pronounced ask-ee and short for American Standard Code for Information Interchange, the most common format for text files in computers on the internet where each character is represented by a unique 7-bit binary code. Extended ASCII uses an 8-bit binary code and allows for international characters.
Unicode An international 16-bit encoding standard that accommodates character sets from multiple languages, with each letter, digit, or symbol being assigned a unique numeric value.
Sample The part of a sound wave that is captured, measured, and assigned a numeric value during digital sound recording.
Bit Depth The amount of memory used to store the numeric value of a sound sample during digital sound recording. 8-bit sound uses eight bits (or one byte) to store the value of each sample. 16-bit sound uses two bytes per sample. Generally speaking, the better the bit depth, the better the sound.
Sampling Rate The number of individual samples taken each second during digital sound recording. Measured in Hertz, the higher the sampling rate, the better the recording. Most modern sound recordings are made at 44.1 kHz.
Frame Rate The number of images, or frames, that are taken each second during digital video recording. Most digital videos have a frame rate of about 30 frames per second.
Resolution The number of pixels in the width and height of each frame in a digital video recording. The higher the resolution, the clearer the image will be.
Color Depth The amount of memory the computer uses to display colors in a digital image or a digital video. 8-bit color images use one byte of data for each pixel. 24-bit color uses three bytes for each pixel.
RGB Display A display on a computer monitor that is made up of sets of tiny red, green, and blue (RGB) lights, each set combining to make a pixel. A pixel will display different colors depending on the brightness of each light.
Raster Images Images stored by dividing a picture into rows of pixels and collecting the color values of each pixel, in order, row-by-row.
Vector Images Images stored by mathematically describing the shapes in the image. A circle might be stored as a center point and the distance from the center point to the circle’s edge. A square is stored as four lines, each with a beginning point and a length. More complex shapes can be stored as a set of small lines.
File Compression A way of reducing the size of files, making them easier to store.
Lossless Compression A compression algorithm, such as GIF, PNG, PDF, and ZIP, that doesn’t affect the original data. A file compressed using a lossless compression algorithm, when decompressed, will be exactly the same as the file before compression, bit for bit.
Lossy Compression A compression algorithm, such as JPG, MP3, and MP4, that slightly alters the data to make it easier to store, taking advantage of the limitations of human sight and hearing, and is usually used for images, videos, and audio files.
Run-Length Encoding A common lossless compression algorithm that looks for repeated patterns of bits or bytes and records the pattern and then number of times the pattern is repeated.
Compression Artifact A patch of pixels in a compressed image or video that have less visible detail than the rest of the image.
Topics Discussed:
How do computers convert physical signals into digital data?
How do computers encode digital image, sound, video and text files?
When is it best to use compressed files? When is it better to use uncompressed files?
