Introduction

Information technology (IT) refers to the combination of computer hardware, software, data, and networks used to collect, process, store, and transmit information. In modern organizations, IT underpins nearly every business activity, from routine record keeping to advanced analytics and global communication. To understand how information systems support organizations, it is first necessary to develop a foundational understanding of how computers work, how software interacts with hardware, and how networks connect systems and people.

This chapter provides a conceptual overview of computer hardware, software, and networking technologies. It is designed for students who may not have a technical background but need sufficient familiarity to understand later discussions of databases, enterprise systems, analytics, cybersecurity, and digital strategy. The goal is not to prepare students to design or repair systems, but to help them understand how these technologies function together as integrated systems.

How do Computers Work?

At a fundamental level, computers operate by executing instructions that manipulate data. These instructions are provided by software programs and carried out by hardware components working in coordination. When a user interacts with a computer—by typing on a keyboard, tapping a touchscreen, or clicking a mouse—those inputs are translated into digital signals that the computer can process.

The central processing unit (CPU) plays a central role in this process. Often described as the “brain” of the computer, the CPU retrieves instructions from memory, interprets them, and performs calculations or logical operations as required. This process occurs through a continuous cycle of fetching instructions, decoding them, and executing them. Modern CPUs perform billions of these cycles per second.

Random access memory (RAM) serves as the computer’s short-term working memory. Programs and data currently in use are loaded into RAM so the CPU can access them quickly. Long-term storage devices, such as solid-state drives (SSDs) or hard disk drives (HDDs), store programs and data even when the computer is powered off. When a program is launched, it is transferred from storage into RAM for active use.

Input and output devices complete the interaction loop. Input devices allow users to provide data and commands, while output devices present results in visual, audio, or printed form. Together, hardware and software form an integrated system that enables computers to perform tasks ranging from simple document editing to complex simulations and data analysis.

Binary – the mathematical language of computers

All data processed by computers is represented internally using binary code. Binary is a number system that uses only two digits—0 and 1—called bits. This representation aligns naturally with electronic circuitry, where signals can be interpreted as either on or off. By combining bits in different patterns, computers can represent numbers, text, images, audio, and video.

Groups of eight bits form a byte, which is the basic unit used to represent characters and small data values. Larger quantities of data are measured using standardized units based on powers of two. A kilobyte represents approximately one thousand bytes, a megabyte represents about one million bytes, and a gigabyte represents about one billion bytes. As storage capacities have increased, terabytes and petabytes have become common in enterprise environments.

Although most users never work directly with binary values, understanding this representation helps explain why computers require structured instructions and why data storage, memory, and processing capacity are measured numerically. Binary logic also underlies the operation of digital circuits and processors.

Core Hardware components

Central Processing Unit (CPU)

The central processing unit is responsible for executing program instructions and coordinating the activities of other hardware components. It performs arithmetic operations, logical comparisons, and control functions that allow software to run. CPU performance is influenced by factors such as clock speed, number of processing cores, and architectural design.

Modern CPUs often contain multiple cores, allowing them to perform several tasks simultaneously. This capability is especially important for multitasking environments and applications that can divide work across parallel processes.

Graphics Processing Unit (GPU)

he graphics processing unit is a specialized processor designed to handle visual and graphical computations. Originally developed to render images and video efficiently, GPUs are now also widely used for data-intensive tasks such as machine learning and scientific computing. By offloading certain types of calculations from the CPU, GPUs can significantly improve overall system performance.

Motherboard and firmware

The motherboard is the main circuit board that connects and coordinates all hardware components. It provides physical connections and communication pathways among the CPU, memory, storage devices, and peripherals. Embedded on the motherboard is firmware—typically implemented as UEFI—which initializes hardware components and starts the operating system when the computer powers on.

Firmware occupies a unique position between hardware and software. It is stored in non-volatile memory and provides low-level control that allows the operating system to interact reliably with physical components.

Memory – RAM and ROM

RAM, or random access memory, is a type of computer memory that is used to temporarily store data and program instructions that are currently in use by the computer’s CPU. RAM is volatile, meaning that it requires power to maintain its contents, and is cleared when the computer is turned off. RAM is important for computer performance because it provides fast access to data and program instructions, allowing the CPU to work efficiently.

ROM, or read-only memory, is a type of computer memory that is used to store permanent data and program instructions that are essential to the computer’s operation, such as the BIOS or UEFI firmware. ROM is non-volatile, meaning that it does not require power to maintain its contents, and is not erased when the computer is turned off. ROM is important for computer operation because it provides essential instructions and data that the computer needs to function properly.

RAM and ROM are both used in a computer to store and access data and program instructions. RAM is used to temporarily store data while the computer is running, while ROM is used to store permanent data and program instructions that are necessary for the computer to function. Together, RAM and ROM provide a complete memory system for a computer, allowing it to perform a wide range of tasks and run a variety of software applications.

Data Storage

Data on a computer can be stored in various ways, such as on hard drives, solid-state drives (SSD), and removable media like USB flash drives or CDs/DVDs.

Hard drives are mechanical storage devices that use spinning disks to read and write data, with the data being accessed by magnetic read/write heads. Hard drives store data even when a computer is turned off and typically have a larger storage capacity than SSDs, making them ideal for storing large amounts of data.

Solid-state drives (SSD) use electronic circuits to store data instead of mechanical spinning disks. They are faster than hard drives because there are no moving parts that need to be accessed. Their storage capacity is generally smaller and more expensive compared to hard drives. They are ideal for use as the primary or boot drive because they offer faster boot times and faster application load times, making them ideal for people who need the speed more than large storage capacity.

Removable media like USB flash drives, CDs/DVDs, and memory cards are used for storing and sharing data, especially when portability is needed. They can be inserted into a USB or memory card port on a computer or mobile device, and data can be added, deleted, or modified as needed. They are not ideal for use as a primary storage device, but they’re a great way to back up or transfer data between computers or as temporary storage to free up computer memory.

Input and Output

Input devices allow users to interact with computing systems by entering data and commands. Common examples include keyboards, mice, microphones, cameras, and touchscreens. Output devices present information in usable form, such as displays, speakers, printers, and projectors.

Input and output devices are fundamental to the operation of computer systems. Generically, these are often called peripheral devices because they operate outside the core components of the computer itself.  Peripherals are often wired devices that connect to a computer’s Universal Serial Bus (USB), High Definition Multimedia Interface (HDMI), or similar port.  Some peripheral devices may use Bluetooth technology to connect peripherals to a computer wirelessly.   

Bluetooth allows devices to communicate with each other wirelessly over short distances. It is commonly used for peripherals such as wireless mice, keyboards, and headphones, as well as for file transfers between devices such as smartphones and computers. Bluetooth works by using radio waves to establish a connection between two devices and exchanging data between them. The devices must be within close proximity to each other, usually within a few meters, for the Bluetooth connection to work. This technology provides a convenient and efficient way for users to connect and use peripherals with their computers without the need for cables or wires.

Introduction to Software

Software consists of the programs and instructions that tell hardware how to operate. Without software, hardware would be incapable of performing meaningful tasks. Software governs everything from basic system startup to complex enterprise analytics.

Software is typically categorized by function, with operating systems providing foundational services, application software enabling user tasks, and specialized systems supporting organizational processes.

Types of Software

Operating Systems

An operating system (OS) is the primary software layer that manages hardware resources and provides services to applications. It controls memory allocation, processor scheduling, file systems, and device access. Common desktop and mobile operating systems include Windows, macOS, Linux, Android, and iOS.

The operating system acts as an intermediary between users, applications, and hardware. By providing standardized interfaces, it allows application developers to write software applications without needing to manage the hardware directly. This abstraction is essential for system stability, security, and usability.
