Study Notes
Introduction to Computers
- A computer is an electronic device that manipulates data, storing, retrieving, and processing it.
- Hardware refers to the physical components of a computer, while software consists of instructions that tell hardware how to function.
Types of Computers
- Desktop Computers: Designed for stationary use, larger and more powerful due to separate components.
- Laptops: Portable computers powered by batteries or AC, usable in various locations.
- Servers: Devices that accept and respond to requests from client programs.
- Tablets: Mobile devices sized like a hardcover book, capable of internet browsing and running software, primarily through touch screens.
- Smartphones: Advanced mobile phones that enable internet browsing and software usage, with touch screen interfaces.
Personal Computer Evolution
- Macintosh: Introduced in 1984, first widely sold computer with a Graphical User Interface (GUI).
- IBM PC: Launched in 1981, marking the beginning of personal computers.
Basic Parts of a Computer
- System Unit: Core component, usually a rectangular box housing essential hardware.
- Mouse: Input device for interacting with the computer screen.
- Monitor: Output device displaying video and text; also referred to as VDT or VDU.
- Keyboard: Primary input device for data entry.
- Speakers: Output devices for sound, can be integrated or external.
- Printer: External device that produces hard copies of digital data.
Internal Hardware Components
- Motherboard: Main circuit board hosting the CPU and other essential components.
- Motherboard Form Factors: Specifications determining size, power supply type, and port locations.
- CPU (Central Processing Unit): Executes instructions and performs basic operations for programs.
- Clock Speed: Measures CPU performance, indicating how many instructions are processed per second.
- FSB (Front Side Bus): Connects the CPU to system memory, affecting performance.
CPU Types
- 32-bit CPU: Older processor type, less efficient in instruction processing compared to its 64-bit counterpart.
- 64-bit CPU: More efficient in processing instructions, supporting larger data structures.
Memory Types
-
Random Access Memory (RAM): Volatile memory used for temporary data storage; varying types include:
- SIMMs (Single Inline Memory Modules): Older RAM type in various sizes, usually with lower capacity.
- DIMMs (Dual Inline Memory Modules): Speedier variants designed for modern CPUs, with more pins and higher capacity.
- SDRAM (Synchronous Dynamic RAM): A memory type that synchronizes with the CPU for enhanced speed.
-
DDR (Double Data Rate): Memory standard with multiple generations:
- DDR2: Released in 2003, faster and more efficient than DDR.
- DDR4: Launched in 2014, offering higher bus speeds and efficiency improvements over DDR3.
