Explicação

## Step 1: Write out the absolute pathname for specified files<br />### The absolute pathname includes the full path from the root directory to the file.<br />- For `MID.TXT`: The path is `/SCHOOL/A/TEACHER/MID.TXT`<br />- For `ASSIGNMENT.DOC`: The path is `/SCHOOL/A/TEACHER/ASSIGNMENT.DOC`<br />- For `ROSTER.XLS`: The path is `/SCHOOL/B/STUDENTS/GRADE 10/ROSTER.XLS`<br />- For `NIO`: The path is `/SCHOOL/B/STUDENTS/GRADE 10/SECTION.ABC/NIO`<br /><br />## Step 2: Write out the relative pathname for specified files using given working directories<br />### The relative pathname is the path from the current working directory to the target file.<br />- For `PRINT.RTF` with `TEACHER` as the working directory: The path is `PRINT.RTF`<br />- For `SECTION.ABC` with `STUDENTS` as the working directory: The path is `GRADE 10/SECTION.ABC`<br /><br />## Step 3: How files are deleted immediately without moving to Recycle Bin<br />### Files can be permanently deleted by using specific commands or key combinations that bypass the Recycle Bin. For example, in Windows, pressing `Shift + Delete` will delete a file immediately.<br /><br />## Step 4: Identifying different types of files on a computer<br />### Files can be identified by their extensions (e.g., `.txt`, `.docx`, `.xls`) which indicate the type of file and the application used to open them. Additionally, file properties and metadata can provide more information about the file type.<br /><br />## Step 5: Advantages of file conversion<br />### File conversion allows compatibility across different software, reduces file size, improves accessibility, and ensures better data preservation.<br /><br />## Step 6: Importance of saving files in different formats<br />### Saving files in different formats ensures compatibility with various applications, facilitates sharing and collaboration, and preserves the integrity and formatting of the document.<br /><br />## Step 7: Use of zipped files<br />### Zipped files compress multiple files into a single archive, reducing storage space and making it easier to transfer and share large amounts of data.<br /><br />## Step 8: Types of drives available to store files on a computer system<br />### Common types of drives include:<br />- Hard Disk Drive (HDD) - typically labeled as `C:`<br />- Solid State Drive (SSD) - also often labeled as `C:`<br />- Optical Drive (CD/DVD) - typically labeled as `D:` or `E:`<br />- USB Flash Drive - labeled as the next available letter after internal drives<br /><br />## Step 9: Definition and characteristics of signals in transmission media<br />### A signal is an electrical or electromagnetic representation of data. Characteristics include:<br />- Analog signals: Continuous waves that vary over time.<br />- Digital signals: Discrete pulses representing binary data.<br />- Transmission media characteristics: Bandwidth, latency, noise resistance, and attenuation.<br /><br />## Step 10: Factors to consider when choosing a transmission medium<br />### Factors include bandwidth, cost, distance, interference susceptibility, installation complexity, and environmental conditions.<br /><br />## Step 11: Application areas of radio waves, microwaves, and infrared<br />### <br />- Radio waves: Used in broadcasting, communication systems, and wireless networking.<br />- Microwaves: Used in satellite communication, radar, and microwave ovens.<br />- Infrared: Used in remote controls, thermal imaging, and short-range communication.
