A Wireless Access Point's SSID Broadcast is what allows a person or computer to easily identify a wireless network, turning this off will help mask/hide a network's identification.

Wikipedia

In IEEE 80211 wireless local area networking standards (including Wi-Fi), a service set is a group of wireless network devices which share a service set identifier (SSID)—typically the natural language label that users see as a network name (For example, all of the devices that together form and use a Wi‑Fi network called Foo are a service set) A service set forms a logical network of nodes operating with shared link-layer networking parameters they form one logical network segment A service set is either a basic service set (BSS) or an extended service set (ESS) A basic service set is a subgroup, within a service set, of devices that share physical-layer medium access characteristics (e

Answer Description

If the battery is not charging and the laptop powers off when plugged in, it is most likely an issue with the power cord or DC jack. Remember: Laptops do not convert AC->DC. The power is converted by the power cord before reaching the laptop's DC jack.

Wikipedia

A DC connector (or DC plug, for one common type of connector) is an electrical connector for supplying direct current (DC) power. Compared to domestic AC power plugs and sockets, DC connectors have many more standard types that are not interchangeable. The dimensions and arrangement of DC connectors can be chosen to prevent accidental interconnection of incompatible sources and loads. Types vary from small coaxial connectors used to power portable electronic devices from AC adapters, to connectors used for automotive accessories and for battery packs in portable equipment.

In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted network and an untrusted network, such as the Internet.

Answer Description

A full format will delete all data on a disk, scan the disk for bad sectors, and then install the operating system. The Quick format will delete data, install the operating system, but not scan the disk for bad sectors.

Wikipedia

Disk formatting is the process of preparing a data storage device such as a hard disk drive, solid-state drive, floppy disk, memory card or USB flash drive for initial use. In some cases, the formatting operation may also create one or more new file systems. The first part of the formatting process that performs basic medium preparation is often referred to as "low-level formatting". Partitioning is the common term for the second part of the process, dividing the device into several sub-devices and, in some cases, writing information to the device allowing an operating system to be booted from it. The third part of the process, usually termed "high-level formatting" most often refers to the process of generating a new file system. In some operating systems all or parts of these three processes can be combined or repeated at different levels and the term "format" is understood to mean an operation in which a new disk medium is fully prepared to store files. Some formatting utilities allow distinguishing between a quick format, which does not erase all existing data and a long option that does erase all existing data. As a general rule, formatting a disk by default leaves most if not all existing data on the disk medium; some or most of which might be recoverable with privileged or special tools. Special tools can remove user data by a single overwrite of all files and free space.

Answer Description

As an IT, you have access to personal data. You should always get customer permission before copying or changing it.

Wikipedia

Client confidentiality is the principle that an institution or individual should not reveal information about their clients to a third party without the consent of the client or a clear legal reason. This concept, sometimes referred to as social systems of confidentiality, is outlined in numerous laws throughout many countries.The access to a client's data as provided by the institution in question is usually limited to law enforcement agencies and requires some legal procedures to be accomplished prior to such action (e.g.: court order issued, etc.). This applies to bank account information or medical record. In some cases the data is by definition inaccessible to third parties and should never be revealed; this can include confidential information gathered by attorneys, psychiatrists, psychologists, or priests. One well known result that can seem hard to reconcile is that of a priest hearing a murder confession, but being unable to reveal details to the authorities. However, had it not been for the assumed confidentiality, it is unlikely that the information would have been shared in the first place, and to breach this trust would then discourage others from confiding with priests in the future. So, even if justice was served in that particular case (assuming the confession led to a correct conviction), it would result in fewer people taking part in what is generally considered a beneficial process. This could also be said of a patient sharing information with a psychiatrist, or a client seeking legal advice from a lawyer.

Answer Description

Many video cards, especially those used in gaming computers, require a 6-pin power connector from the power supply to operate. Along with this, you should check that the video card is properly seated. Drivers work with the operating system (not the BIOS) and the video is not working prior to boot, meaning it is unlikely to be a driver issue.

Answer Description

WPA2 is the newest, and most secure WiFi Encryption.

Wikipedia

Wi-Fi Protected Access (WPA), Wi-Fi Protected Access 2 (WPA2), and Wi-Fi Protected Access 3 (WPA3) are the three security certification programs developed after 2000 by the Wi-Fi Alliance to secure wireless computer network. The Alliance defined these in response to serious weaknesses researchers had found in the previous system, Wired Equivalent Privacy (WEP).WPA (sometimes referred to as the TKIP standard) became available in 2003. The Wi-Fi Alliance intended it as an intermediate measure in anticipation of the availability of the more secure and complex WPA2, which became available in 2004 and is a common shorthand for the full IEEE 802.11i (or IEEE 802.11i-2004) standard. In January 2018, Wi-Fi Alliance announced the release of WPA3 with several security improvements over WPA2.

Answer Description

Port 25 is used by SMTP, which is used to send email. While POP3 (110), and IMAP (143) are instead used to receive email.

Wikipedia

The Simple Mail Transfer Protocol (SMTP) is an Internet standard communication protocol for electronic mail transmission. Mail servers and other message transfer agents use SMTP to send and receive mail messages. User-level email clients typically use SMTP only for sending messages to a mail server for relaying, and typically submit outgoing email to the mail server on port 587 or 465 per RFC 8314. For retrieving messages, IMAP (which replaced the older POP3) is standard, but proprietary servers also often implement proprietary protocols, e.g., Exchange ActiveSync. SMTP's origins began in 1980, building on concepts implemented on the ARPANET since 1971. It has been updated, modified and extended multiple times. The protocol version in common use today has extensible structure with various extensions for authentication, encryption, binary data transfer, and internationalized email addresses. SMTP servers commonly use the Transmission Control Protocol on port number 25 (for plaintext) and 587 (for encrypted communications).

Answer Description

Reducing the radio power to help keep wireless signals from traveling farther than necessary can help hide the network's existence. Keep in mind this isn't a security feature and that there are other steps that should be taken to secure the network that are outside the scope of the question.

Wikipedia

In computer networking, a wireless access point, or more generally just access point (AP), is a networking hardware device that allows other Wi-Fi devices to connect to a wired network. As a standalone device, the AP may have a wired connection to a router, but, in a wireless router, it can also be an integral component of the router itself. An AP is differentiated from a hotspot which is a physical location where Wi-Fi access is available. Although WAP has been used incorrectly to describe an Access Point, the clear definition is Wireless Application Protocol which describes a protocol rather then a physical device.

Answer Description

Tailgaiting is when an unauthorized person "tails" an authorized person through a secured entryway without the authorized person's knowledge.

Wikipedia

In security, piggybacking, similar to tailgating, refers to when a person tags along with another person who is authorized to gain entry into a restricted area, or pass a certain checkpoint. It can be either electronic or physical. The act may be legal or illegal, authorized or unauthorized, depending on the circumstances. However, the term more often has the connotation of being an illegal or unauthorized act.To describe the act of an unauthorized person who follows someone to a restricted area without the consent of the authorized person, the term tailgating is also used. "Tailgating" implies no consent (similar to a car tailgating another vehicle on a road), while "piggybacking" usually implies consent of the authorized person.Piggybacking came to the public's attention particularly in 1999, when a series of weaknesses were exposed in airport security. A study showed that the majority of undercover agents attempting to pass through checkpoints, bring banned items on planes, or board planes without tickets, were successful. Piggybacking was revealed as one of the methods that was used in order to enter off-limits areas.

Answer Description

Often when installing Windows onto an external RAID array, a driver is required for Windows to detect the hard drives.

Wikipedia

In computing, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to know precise details about the hardware being used. A driver communicates with the device through the computer bus or communications subsystem to which the hardware connects. When a calling program invokes a routine in the driver, the driver issues commands to the device (drives it). Once the device sends data back to the driver, the driver may invoke routines in the original calling program. Drivers are hardware dependent and operating-system-specific. They usually provide the interrupt handling required for any necessary asynchronous time-dependent hardware interface.

Answer Description

Although the technician was able to locate and remove a virus, that virus was not the cause of the user's issues. The technician should continue to troubleshoot the computer.

Wikipedia

Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms. Determining the most likely cause is a process of elimination—eliminating potential causes of a problem. Finally, troubleshooting requires confirmation that the solution restores the product or process to its working state. In general, troubleshooting is the identification or diagnosis of "trouble" in the management flow of a system caused by a failure of some kind. The problem is initially described as symptoms of malfunction, and troubleshooting is the process of determining and remedying the causes of these symptoms. A system can be described in terms of its expected, desired or intended behavior (usually, for artificial systems, its purpose). Events or inputs to the system are expected to generate specific results or outputs. (For example, selecting the "print" option from various computer applications is intended to result in a hardcopy emerging from some specific device). Any unexpected or undesirable behavior is a symptom. Troubleshooting is the process of isolating the specific cause or causes of the symptom. Frequently the symptom is a failure of the product or process to produce any results. (Nothing was printed, for example). Corrective action can then be taken to prevent further failures of a similar kind. The

Answer Description

This printer will not connect to the network, so you will need to use a print server as an intermediary device.

Wikipedia

In computer networking, a print server, or printer server, is a type of server that connects printers to client computers over a network. It accepts print jobs from the computers and sends the jobs to the appropriate printers, queuing the jobs locally to accommodate the fact that work may arrive more quickly than the printer can actually handle. Ancillary functions include the ability to inspect the queue of jobs to be processed, the ability to reorder or delete waiting print jobs, or the ability to do various kinds of accounting (such as counting pages, which may involve reading data generated by the printer(s)). Print servers may be used to enforce administration policies, such as color printing quotas, user/department authentication, or watermarking printed documents. Print servers may support a variety of industry-standard or proprietary printing protocols including Internet Printing Protocol, Line Printer Daemon protocol, NetWare, NetBIOS/NetBEUI, or JetDirect. A print server may be a networked computer with one or more shared printers. Alternatively, a print server may be a dedicated device on the network, with connections to the LAN and one or more printers. Dedicated server appliances tend to be fairly simple in both configuration and features. Print server functionality may be integrated with other devices such as a wireless router, a firewall, or both. A printer may have a built-in print server. All printers with the right type of connector are compatible with all print servers; manufacturers of servers make available lists of compatible printers because a server may not implement

Answer Description

Because this is a non-domain (local) user account the Local Security Policy is the cause of the issue. Accessing the policy to determine account requirements will solve the problem.

Wikipedia

Group Policy is a feature of the Microsoft Windows NT family of operating systems (including Windows 7, Windows 8.1, Windows 10, Windows 11, and Windows Server 2003+) that controls the working environment of user accounts and computer accounts. Group Policy provides centralized management and configuration of operating systems, applications, and users' settings in an Active Directory environment. A set of Group Policy configurations is called a Group Policy Object (GPO). A version of Group Policy called Local Group Policy (LGPO or LocalGPO) allows Group Policy Object management without Active Directory on standalone computers.Active Directory servers disseminate group policies by listing them in their LDAP directory under objects of class groupPolicyContainer. These refer to fileserver paths (attribute gPCFileSysPath) that store the actual group policy objects, typically in an SMB share \\domain.com\SYSVOL shared by the Active Directory server. If a group policy has registry settings, the associated file share will have a file registry.pol with the registry settings that the client needs to apply.The Policy Editor (gpedit.msc) is not provided on Home versions of Windows XP/Vista/7/8/8.1/10/11.
