Study Notes
Types of Computers
- Computers are classified based on operation and configuration
Types Based on Operation
- Principles of operation determine the type of computer
- There are three types of computers: analog, digital, and hybrid
Analog Computers
- Computing devices working on a continuous range of values.
Digital Computers
- Computers operating on the binary number system, with only two digits: 0 and 1, each is known as a bit
Hybrid Computers
- Computers that combine the desirable features of both analog and digital computers.
Types Based on Configuration
- Computers are classified into four types, based on their performance and capacity: supercomputers, mainframe computers, mini computers, and microcomputers.
Supercomputers
- They have the best processing capacity, and are the most expensive
- Supercomputers process billions of floating-point instructions per second and are used for applications requiring intensive numerical computations like stock analysis and weather forecasting
- Examples include: China's Tianhe-2 and IBM's Blue Gene (1 Thousand Billion FLOPS/s).
Mainframe Computers
- They process data at very high speeds, processing hundreds of millions of instructions per second.
- They are normally used in banking, airlines, and railways
- Example: IBM System z9
Mini Computers
- Alternatively known as mid-range computers
- They are lower than mainframe computers in terms of speed and storage capacity
- They are less expensive than mainframe computers
- Some features of mainframes are unavailable in mini computers
Micro Computers
- Resulted from the invention of the microprocessor or, single chip CPU
- They are much cheaper
- Examples include: Desktop computers, workstations, laptops/notebooks, and handheld devices (PDAs)
Information & Communication Technology (ICT)
- Information: Refers to useful data
- Communication: The process of sharing information
- Technology: The application of science, including computers, networks, software, and mobile phones
ICT vs IT
- Information and Communication Technology (ICT) is a broader designation for Information Technology (IT)
- ICT includes all communication technologies like the internet, wireless networks, cell phones, and software
Components of ICT

Hardware
- Hardware includes physical devices used in ICT, such as computers, smartphones, and tablets.
- Types includes: Personal Computers (PCs), servers, smartphones/tablets, and peripheral devices (printers, scanners).
- Its role is to execute software commands, perform calculations, and store data.
- Without hardware, software cannot run, and networks are unable to function.
Software
- Software is a set of programs that run on hardware.
- Includes: Operating Systems (Windows, macOS, Android), applications (MS Office, Photoshop), and Utility Software (antivirus, backup tools).
- Its role is essential for enabling communication between the user and the hardware, translates commands into actions, and allows users to interact with devices and complete tasks.
ICT Platforms
- Platforms provide infrastructure for applications.
- Includes: Operating Systems (Windows, Linux, iOS), Cloud Platforms (AWS, Microsoft Azure), and Database Systems (MySQL, Oracle).
- ICT platforms provide the infrastructure for running applications, managing data, and delivering services, they also enable access to computing power and data storage from any location.
Networks
- Networks enable devices to communicate and share resources.
- Includes: Local Area Network (LAN), Wide Area Network (WAN), and Wireless Networks (Wi-Fi, 5G).
- Networks facilitate the sharing of data, resources, and communication across multiple devices and locations, and connect billions of devices globally.
Data Storage
- Data storage preserves and manages digital information.
- Includes: local storage on Hard Drives (HDD, SSD) and USBs and cloud storage on Google Drive, Dropbox, and OneDrive.
- Data storage is essential for maintaining and accessing information, locally or via the cloud, allowing organizations/individuals to manage and utilize data effectively.
Internet
- Use of Internet
- Connectivity
- Internet Growth
- Famous Browsers
- Search Engine Market Share
What is the Internet?
- It is a global computer network providing varied information and communication facilities, consisting of interconnected networks using standardized communication protocols

Uses for the Internet
- Applying for jobs or schools
- Filling out government forms
- Checking bank accounts
- Communicating with family, friends, and co-workers
- To do research
- Learn new skills
- Reading news
- Watching videos
Ways to Connect to the Internet
- Dial-Up (Old/outdated)
- High Speed/DSL
- Wireless Connection (Wi-Fi)
Dial-Up
- It requires a computer, a phone-line, and an Internet Service Provider (ISP)
High Speed (Cable/DSL) Connection
- This travels through underground fiber-optic cables
- It requires a modem to connect your computer
- This connection is faster than Dial-Up
Wireless Internet Connection (Wi-Fi)
- It requires a wireless enabled device
- Your computer can pick up signals from wireless networks
- Some networks may require a password or subscription
- No physical connection is required.
