Overview

Introduction

Welcome to the Managing Units of Measure - Disks, Network Throughput and Processor Practice Lab. In this module, you will be provided with the instructions and devices needed to develop your hands-on skills.

Learning Outcomes

In this module, you will complete the following exercises:

  • Exercise 1. Create Disk Volumes with Different Sizes
  • Exercise 2. Measure Network Throughput
  • Exercise 3. Retrieve Processor System Information

After completing this lab, you will be able to:

  • Shrink a disk volume
  • Create and format partitions
  • Create virtual hard disks with Disk Management
  • Download and install Wireshark
  • Collect information on network throughput
  • Download and install CPU-Z
  • Access system information
  • Verify system information

Exam Objectives

The following exam objectives are covered in this lab:

  • 1.5 Compare and contrast common units of measure.

Lab Duration

It will take approximately 1 hour to complete this lab.

Exercise 1 - Create Disk Volumes of Different Sizes

A bit (binary digit) is a single unit of information and is represented as a binary value of zero or one. Eight bits is equal to one byte. Computer storage media use bytes, a standard of unit measurement for setting hard drive (disk) capacity. For disk storage, 1 kilobyte is equivalent to 1,024 bytes while 1 megabyte is equal to 1,024 kilobytes, because a byte is composed of 8 bits in the binary system (2^10). Therefore, you will increment by 1,024 units as you go up the kilo, mega, giga, terascale and so on.

In this exercise, you will learn how to create partitions of different sizes using the existing disk volumes of a Windows 10 device. Partitions are logical segments on a physical hard disk. The operating system considers each partition as a separate entity where an operating system can store files and install applications.

Learning Outcomes

After completing this exercise, you will be able to:

  • Shrink a disk volume
  • Create and format partitions
  • Create virtual hard disks with Disk Management

Exercise 2 - Measure Network Throughput

Network throughput in data communications is defined as the amount of data transmitted in one direction over a link either on wired or wireless media, divided by the time (seconds) to transmit it and expressed in bits per second (bps). Network protocols use “bits” as a standard unit of measurement of network speed.

In this exercise, you will learn how to measure network throughput by connecting to the Internet and downloading a file hosted on an intranet site using a network analyzer called Wireshark.

Learning Outcomes

After completing this exercise, you will be able to:

  • Download and install Wireshark
  • Collect information on network throughput

Exercise 3 - Retrieve Processor System Information

The central processing unit (CPU), also called a processor, is the device that executes instructions from computer’s hardware peripherals and installed software. A CPU is used on different devices like server computers, desktops, laptops, tablets, smartphones and smart televisions. CPUs can likewise be found in the Internet of Things (IoT) are devices that promise anywhere connectivity that will enable billions of devices to talk to each other and to people. Voice controllers, security cameras, smart alarm clocks, thermostat controls, and many others are some examples of IoT devices.

In this exercise, you will view a virtual machine’s CPU information using a tool called CPU-Z.

Learning Outcomes

After completing this exercise, you will be able to:

  • Download and install CPU-Z
  • Access system information
  • Verify system information
