Professionalism: Punctuality, listen to customer, take notes, clarify problems, positive attitude, speak clearly, project confidence, be culturally sensitive, set and meet expectations, avoid distractions (phone calls, texting, social media), and avoid confidential data. 45. An integer is a whole number that can be positive, negative, or zero. For example, 2, –2, 0, 201, –201. A string represents text rather than numbers. It is enclosed with quote marks like “This is a short string.” 46. Basic loops let a program execute the same statement several times. 47. PowerShell will always place a $ before a variable—for example, $i . 48. Scripting types: Windows PowerShell (.ps1); batch file (.bat); Linux Bash (.sh); Python (.py); Visual Basic script (.vbs); JavaScript (.js). 49. Remote access: RDP (Remote Desktop Protocol, port 3389), SSH (Secure Shell, port 22, ex. PuTTY), Virtual Network Computing (VNC). 220-1002 1. Windows 10 min. requirements: CPU = 1 GHz; RAM = 1 GB for 32-bit, 2 GB for 64-bit; free disk space = 16 GB for 32-bit, 32 GB for 64-bit. 2. Common system tools include Device Manager, System Information tool, Task Manager, and msconfig . 3. Remote Desktop (RDP) software enables a user to see and control the GUI of a remote computer. 4. Workgroups are for small networks (20 maximum inbound sessions to a Windows client). Domains are for larger networks and are controlled by a domain controller that has Active Directory installed. 5. The %systemroot% (or %windir%) is C:\Windows by default. 6. Windows boot files include Bootmgr, Winload.exe, BCD. 7. In Windows, DIR is the directory command. Navigate with the CD command, including CD.. and CD\ . 8. Files can be manipulated with del (deletes), copy (copies files), robocopy (robust file copy, copies multiple files and directory trees). 9. Drives can be manipulated with format (writes new file system), diskpart (does everything Disk Management does but in Command Prompt). 10. File checking command-line tools that can be used in Windows include Chkdsk ( /F fixes errors; /R locates bad sectors and recovers info) and SFC (System File Checker). SFC /scannow is common. 11. A hard drive using GPT (GUID Partition Table) can have 128 partitions and go beyond MBR’s 2 TB limit. GPT is stored in multiple locations. Requires UEFI- compliant motherboard. A hard drive using MBR (master boot record) can have four partitions: up to four primary partitions but only one extended partition. Logical drives are sections of an extended partition. The Active partition is the one that is booted from; it usually contains the OS. Any section of a drive with a letter is called a volume. Volumes in dynamic drives can be resized, but not in basic drives. NTFS is the most common file system in Windows. exFAT for flash drives. 12. Backups can be accomplished in Windows 10/8 with File History, and in Windows 7 with Backup and Restore. 13. System Restore can fix issues caused by defective hardware or software by reverting to an earlier time.
