Motherboards connect the various components of a computer system and determine the computer's capabilities. They come in different form factors and have varying components depending on the intended use of the system. Faster motherboards support higher CPU speeds and more memory through wider data buses that transfer information between components. Buses, sockets, and adapter cards are key components that expand the motherboard's capabilities by allowing additional devices to connect and communicate with the CPU and other parts. Common adapter cards include video graphics cards, sound cards, and network interface cards. User interfaces also connect through the motherboard and can be command-line based or graphical user interfaces using icons, windows, and a mouse.
Components of Computer
- 4. Types of Motherboard Motherboard Speed of motherboardComponents of motherboard A s form factor? which components are a Motherboard is called r. B erboard: C herboard: rd depends on ), RAM Bus, CPU CPU to the n range MHz’s. affect a D
- 6. What is it… • A bus is a set (group) of parallel lines that information (data, addresses, instructions, and other information) travels on inside a computer. • A Bus is a system that moves data from one source to another. • Information travels on buses as a series of electrical pulses, each pulse representing a one bit or a zero bit
- 7. BUSES
- 8. Buses Channel that allows devices inside computer to communicate with each other. • connects processor and RAM • determines number of bits transmitted at one time • Word size is the number of bits processor can interpret and execute at a given time.
- 9. SOCKETS Computer sockets are the built-in interfaces on motherboard. that accept various hardware components.
- 10. ADAPTER CARDS Computer card is an expansion device that provides an existing computer with certain added capabilities. • What these capabilities are depends of course on the computer card. • Some Example (VGA, Sound, Modem)
- 11. VGA • A video card (also called a display card, graphics card, display adapter or graphics adapter) is an expansion card which generates a feed of output images to a display (such as a computer monitor). • Frequently, these are advertised as discrete or dedicated graphics cards, emphasizing the distinction between these and integrated graphics.
- 12. Sound Cards • A sound card (also known as an audio card) is an internal expansion card that provides input and output of audio signals to and from a computer under control of computer programs. • Typical uses of sound cards include providing the audio component for multimedia applications such as music composition, editing video or audio, presentation, education and entertainment (games) and video projection.
- 13. • Local area network card or the LAN card is required which enables the connection of the computers in a network. It is a piece of hardware which is connected inside the PC linking the computer network. Network Card/Modem Card/LAN Card
- 14. INTERFACE Command line Interface Graphical User Interface
- 15. CLI CLI (Command Line Interface): A command-line interface (CLI), also known as command-line user interface, console user interface and character user interface (CUI), is a means of interacting with a computer program where the user (or client) issues commands to the program in the form of successive lines of text (command lines).

- 17. GUI GUI (Graphical User Interface): GUI also known as Graphical user interfaces (GUIs). Mouse driven and icon based Windows Are allocated to the use of a particular program or process Contain a title bar, menu bar and widgets
- 18. GUI
- 19. Command Line Interface Graphical User Interface Ease It is difficult to remember its commands. It is also difficult to type commands for different tasks. It is easy to use. It is very easy to remember different sequence of activities to perform a certain task. Control Users have excellent control on the file system. User have better control on the file system. But in some cases they need to use the command line interface to complete a task. Comparison between CLI & GUI
- 20. Multitasking Many command line interfaces are multitasking but they don’t have the ability to display multiple tasks on the screen at the same time. In GUI multiple tasks can be performed at the same time. These tasks are also displayed on screen. GUI are faster in multitasking. Speed Command Line Interface is faster to perform a task. GUI is slower while performing a certain task. Scripting In command line interface a user can write the commands in sequence and use them to perform a certain task. GUI provides shortcuts to perform task fast, but it does not come close in comparison to what is available through command line Comparison between CLI & GUI
