System clock -
Like a bass drum. Clock speed is measured in gigahertz (GHz) or billions of bits per second open architecture allow expanding their systems by providing expansion slots.
Closed Architecture -users can not add new device.
Expansion cards are also called plug -in boards, controller cards, adaptor cards and interface cards.
Video cards- Graphics cards -conver electronic signals into video signals.
Sound cards- convert electronic signals into audio signals and vice versa.
Modem cards- Convert digital into analog and analog into digital signals.
Network interface cards (NIC) / network adapter card - use to connect computer with other computer.
T. V tuner cards-also known as television boards, video recorder card and video computer cards. Convert TV signals into digital signals.
Plug and play is a set of hardware and software automatically configure the device and ready to run.
Bus lines- simply known as a bus- connect the part of the CPU to each other. The number of bits that can travel simultaneously down a bus is known as the bus width.
Name- ISA -industry standard architecture
Speed- 8 to 16 bits
Use- personal computer
Name - PCI- peripheral component interconnect
Speed- 32 to 64 bits
Use - Graphic interface
AGP-Accelerated graphic port
USB-Universal serial bus
HPSB-High performance
20times faster. Graphic Interface Than ISA. Graphics and
Twice fast. 3 D animation
Than PCL. To connect several
Twice fast. external devices
Than AGP. Digital camcorders & Serial bus / FireWire buses Equal to USB vidio editing software
Ports -ports are connecting sockets on the system unit.
Serial ports-send data one bit at a one time and good for sending data over a long distance. Use to connect mouse, keyboard, modem etc.
Parallel ports-send eight bit of data simultaneously across eight parallel wire. This port is used to connect printers.
Universal serial bus (USB) ports-faster port used to connect several devices.
Fire wire ports- also known as high performance serial bus (HPSB) - faster port used to connect camcorder.
PCI express ( PCLe) and serial ATA (SATA) - typically used to connect magnetic and optical disc drives to the system board with greater speed and other buses.
Specialized ports
MIDI (musical instrument digital interface) - use to connecting musical instruments like and electronic keyboard.
IrDA (infrared data association) - provide a wireless mechanism for transferring data between devices.
Power supply :-
Computer requires direct connect (DC) supply. Desktop computers used power supply unit to convert alternating current (AC) to DC. Notebook and handheld computers use ACadapters and batteries.
Types of booting :-
Cold booting :- when the computer is off, and make it on then this booing is called a cold booting in this system it displaythe type of Proccesor, memory of the computer etc.
Warm booting :- when the computer is on but because of some problem the computer is stopped. To make switch off and make it again on, this type is called as warm booting in this case memory and other information is not tested.
Operating system :-
2. Software -
"Anything abstract/intangible about a computer system (i.e.which exists, but cannot be touched or seen) is a part of the software of the system ",It is a combination of data (information) and program (instruction) to give the desired result this makes computer to work. A set instruction, stored digitally within the computer's memory, which tells the computer system what to do.
Types of software :
Basically there are two types of software:
1) System software
2) Application software
