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