Hey there, information technology lovers!
In this blog, I will talk about some of the basic computer skills you should know for IT jobs. We will start with the basic point and add one or two more complex topics.
Information technology (IT) is a process that includes using computers and software to store, protect, process, transmit and retrieve data. Those who work in the IT field install computer systems, provide support to users and create and maintain applications. They might also work in various other capacities, such as system administrators, analysts, DevOps, network engineers, data engineers, QA engineers, and software engineers. You name it; IT is everywhere.
The most basic information everyone should know, regardless of whether you're starting a career in IT or a seasoned pro, the following are some basic skills you should know about IT.
Nearly all computers come with an operating system (OS) pre-installed. An OS is a type of software that manages a computer's hardware and provides a platform for other software. Most people are familiar with the two major desktop OSes, Windows and macOS, but there are many others, such as Linux, Android, and iOS. Each OS has its strengths and weaknesses, but they all provide similar essential functions. However, it is important to remember that there are many different operating systems, and each has unique features and capabilities.
Microsoft was founded in 1975 and is now the world's largest software company. It has many products, including ones for operating systems and business applications. Windows and MS Office are two of the best-known products. They are used by many people all over the world. If you want a career in IT, you need to know how to use these products well. You can develop your software, or other people use these products if you know how they work.
Popular Microsoft products such as Windows and MS Office, especially MS Word, Excel, and PowerPoint, are primarily used everywhere. So, it is better to know about these products if you want to start a career in IT.
The command prompt is a text-based interface that allows you to enter commands into a computer. It is sometimes referred to as the "DOS prompt" because it was used in the MS-DOS operating system. Many IT jobs require a good working knowledge of the command prompt. The command prompt can be valuable in any programming or system administration career. The command prompt can be used to perform tasks such as creating and deleting files, accessing system settings, and running programs.

The syntax is generally straightforward to learn. However, the command prompt can seem daunting if you are unfamiliar with it. Many resources available online can help you understand the basics of syntax. With some practice, you can use the command prompt like a pro!
Networks are essential for computers to communicate with each other. Networking is vital to any computer system. IT professionals must understand how networks work. To build and maintain networks, IT professionals must be familiar with various concepts and technologies, including routers, switches, and protocols. Complex networks can involve hundreds or even thousands of computers and may use multiple technologies, including Ethernet, WiFi, and fiber optic cables. You don't need to be a seasoned pro, but basic networking knowledge is essential for many IT jobs.
DNS is an essential part of the internet. Without DNS, we would have to remember long strings of numbers instead of being able to use easy-to-remember domain names. DNS servers provide an essential service by translating between human-readable domain names and machine-readable IP addresses. Many IT jobs require a good working knowledge of DNS, which is critical to how the internet works. If you want to work in IT, brush up on your DNS knowledge!
When working with computers, several different acronyms and technical terms are essential. One of these is IP, which stands for Internet Protocol. IP addresses are used to identify computers on the Internet, and they play a vital role in many IT jobs. To work with IP addresses, it is essential to have a good understanding of how they are structured and how they function. However, working with IP addresses can be relatively straightforward with little practice.
DHCP is a network protocol that automatically assigns IP addresses to devices connected to a network. DHCP works by assigning a unique IP address to each device on the network. This helps to ensure that each device can communicate with other devices on the network. DHCP also helps to reduce the need for manual configuration of IP addresses. DHCP is an essential protocol for networks of all sizes. DHCP can be used to automatically assign IP addresses to computers, printers, and other devices on the network. This can help reduce the time needed to configure IP addresses manually. DHCP can also help to ensure that each device on the network has a unique IP address. This helps to prevent conflicts between devices on the network. DHCP is a valuable tool for reducing the time and effort needed to configure IP addresses on a network.
In the world of computer networking, a Ping is an essential tool. Ping is a utility that tests the connectivity between two computers. It can test whether a computer is connected to the Internet or whether two computers on a network can communicate. Many IT jobs require a good working knowledge of Ping. Ping works by sending a "ping" packet to a computer and then waiting for a response. If the computer responds, it is considered "alive." The time it takes for the response to arrive is known as the "ping time." Ping times can vary depending on the type of connection and the distance between the two computers. In general, shorter ping times are better because they indicate that the connection is faster. However, other factors, such as network congestion, can also affect ping times. Therefore, IT professionals use Ping to troubleshoot networking problems and to determine whether a particular connection is working correctly.
Windows Powershell is a powerful scripting language that enables you to automate tasks on Windows systems. Powershell scripts can automate system administration tasks, such as creating and managing user accounts, managing file shares, and configuring networking settings. In addition, Powershell can be used to create custom applications that integrate with other Windows components, such as Active Directory and Exchange Server. With its vast array of cmdlets and comprehensive scripting capabilities, Windows Powershell provides a powerful tool for automating almost any task on a Windows system.
Many IT jobs require a good working knowledge of Powershell, so it's worth learning if you're hoping to pursue a career in this field. Plus, it's just convenient to know how to use! Once you get the hang of it, Powershell can make managing your computer's environment a breeze.
Active Directory is a critical part of many IT infrastructure and management jobs. It allows you to control user access to systems and data and manage computers and groups in an organization from a single location. Active Directory can be complex to set up and configure, but once it runs smoothly, it can save time and effort. Good working knowledge of Active Directory is essential for many IT positions, so if you are interested in pursuing a career in this field, you must familiarize yourself with this technology's basics.
Exchange Server is a popular Microsoft product that allows organizations to send and receive emails and manage calendars, contacts, and tasks. Many IT jobs require a good working knowledge of Exchange Server. Exchange Server is a complex product, and there are many different aspects to consider when managing an Exchange installation. One of the essential aspects of Exchange Server is security. With the recent proliferation of malware and ransomware, ensuring that your Exchange installation is properly secured is essential.

As the world increasingly moves online, more businesses rely on databases to store critical data. A database is a collection of information that computers can access. This could include customer records, product catalogs, employee profiles, etc. There are many databases, such as relational, object-oriented, and NoSQL. Each type has its advantages and disadvantages, so it's essential to choose the right one for your needs. For example, a relational database might be a good choice for a business that needs to store a large amount of data in a structured way.
On the other hand, an object-oriented database might be a better fit for a business that needs to store complex data structures. No matter what database you use, proper maintenance is essential to running it smoothly. This includes backing up data, ensuring data integrity, and optimizing performance. With the right database in place, your business can run more efficiently and meet your customer's needs better.
Knowing how the database works and how to set them up and configure them is a valuable skill in IT. Databases are used in various applications, so having this knowledge can give you an edge in your career.
Creating a website is a complex process, but it can be divided into three basic steps:
- Planning: Before you can start creating a website, you need to have a clear idea of what you want the site to achieve. What purpose will it serve? Who is your target audience? What kind of content will you include? Once you answer these questions, you can start planning the site's structure and design.
- Development: Once you plan, you can start developing the website. This involves creating the site's content, coding the pages, and testing the area to ensure everything works as intended.
- Launch: Once the website is complete, you need to launch it so users can access it. This involves choosing a web host and registering a domain name. Once the site is up and running, you can start promoting it to attract visitors.
Creating a website is a complex process, and in IT, there is a separate path for this. So you don't need to be an expert in this area to a land an entry-level position in IT. However, familiarity with the process is a valuable skill set. Websites are used in various applications, so having this knowledge can give you an edge in your career.
You should also know your way around the most common hardware components, such as hard drives, motherboards, CPUs, etc.
