Can I have admin rights

Can I have admin rights?

This is a major question from a few businesses and their users. There are extremely good reasons why this is not done, or a dedicated account created for such tasks; these reasons are: –


Computer Security

If a user has admin rights to the machine or the server; so does any nasty code or applications that is on the system. So if you came across a new threat that managed to get passed your anti-virus, it would have free access to do as it wished as you are an administrator. But if you did not have these rights the damage could be limited to effecting just the one user account, and not the computer / network.


Little Knowledge is dangerous

As in Spiderman, the great phase of “With Great Power Come Great Responsibility”; is completely true with being an computer administrator. We often find users that do have admin rights are often not trained or have some knowledge, and due to this they often tinker with setting they do not understand; because of this more problems for IT support are generally created.


Scripts & Policies

Within most businesses a server or two is at the heart of the network; this gives IT staff control to perform certain tasks or provide services required by the business. Some of these tasks might be every day stuff you take for granted like being able to see a network drive; these drives and other settings are applied to your account & computer via software policies or scripts. Unfortunately giving users admin rights on the network will cause problems with these applying on Windows Vista or newer because of the new protection feature called UAC (User Account Control).

Which SMTP Port to Use

Which SMTP Port to Use?

For email services there are many different SMTP ports to use for sending emails, below are the most recent ports and reasons for use.

Port 25

This port continues to be used primarily for SMTP relaying. SMTP relaying is the transmittal of email from email server to email server.
In most cases, modern SMTP clients (Outlook, Mail, Thunderbird, etc) shouldn’t use this port. It is traditionally blocked, by residential ISPs and Cloud Hosting Providers, to curb the amount of spam that is relayed from compromised computers or servers. Unless you’re specifically managing a mail server, you should have no traffic traversing this port on your computer or server.

Port 465

IANA has reassigned a new service to this port, and it should no longer be used for SMTP communications.

Port 587

This is the default mail submission port. When a mail client or server is submitting an email to be routed by a proper mail server, it should always use this port.

What is USB

What is USB?

USB stands for Universal Serial Bus. This is a communication and connection technology that is used on virtually all computers to connect peripheral devices. Peripheral devices are connected to the computer’s USB port via a USB cable. Some common peripherals are the mouse, keyboard, printer and external hard drive.

What is RAM

What is RAM?

Random access memory (RAM) is the computer’s temporary memory. It is measured in gigabytes (GB) and is used as needed to complete tasks. The amount of RAM a computer has is a significant factor in the computer’s overall speed because the more RAM it has, the faster it can process tasks. Adding more RAM to a computer is the easiest way to instantly increase the computer’s speed.

What is an operating system

What is an operating system?

The operating system or OS, is the software program that a computer uses to perform functions. Microsoft Windows, Mac OS X and Linux are examples of operating systems.
The operating system is the software that runs all the programs on the computer. While all operating systems are designed to accomplish similar tasks, specific programs are often compatible with only one kind of operating system.

What is a web browser

What is a web browser?

A web browser (commonly referred to as a browser) is a software application for retrieving, presenting and traversing information resources on the World Wide Web. An information resource is identified by a Uniform Resource Identifier (URI/URL) and may be a web page, image, video or other piece of content. Hyperlinks present in resources enable users easily to navigate their browsers to related resources.

Although browsers are primarily intended to use the World Wide Web, they can also be used to access information provided by web servers in private networks or files in file systems.

The major web browsers are Google Chrome, Mozilla Firefox, Internet Explorer, Opera, Microsoft Edge and Safari.

What is a SPF Record

What is a SPF Record?

Sender Policy Framework (SPF) is an email validation system designed to prevent email spam by detecting email spoofing. Email spoofing is a common vulnerability, SPF solves this by verifying the senders IP address.
SPF allows administrators to specify which hosts are allowed to send mail from their domain; this is done by creating a specific SPF record (or TXT record) in the Domain Name System (DNS). Mail exchangers use the DNS to check that mail from a given domain is being sent by a host sanctioned by that domain’s administrators.

What is a hard drive?

What is a hard drive?

The hard drive is the storage area. Every file on a computer is stored on the hard drive. The storage capacity of a hard drive is measured in gigabytes (GB). In contrast to RAM, the hard drive is the permanent storage area. While every computer contains an internal hard drive, there are external hard drives as well. External hard drives are often used to back up the information on an internal hard drive.

What is a graphics card

What is a graphics card?

A video card  is an expansion card which generates a feed of output images to a display (such as a computer monitor).
Video cards are also called any of the following: –
  • video adapter
  • display card
  • graphics card
  • graphics board
  • display adapter
  • graphics adapter
Sometimes preceded by the word discrete or dedicated to emphasize the distinction between this implementation and integrated graphics.

What is a CPU

What is a CPU?

CPU is short for central processing unit. The CPU is the part of the computer that is most responsible for the computer’s speed. The CPU’s processing speed is measured in gigahertz (GHz). The CPU can be thought of as the computer’s “engine” with the GHz corresponding to an engine’s horsepower. Each GHz equals 1,000 MHz, so a speed of 2.4 GHz is equal to 2,400 MHz.
