- 11. Central processing unit • The brain of the computer. • Performs most of the computer calculations and runs the operating system and other soft wares smoothly. • It governs the overall speed of the computer. • Cache memory. • The CPU’s speed – Internal clock’s speed (Hertz – Hz)
- 13. Memory • Computer needs working memory for storing the current programs it runs. • Main memory or primary storage.
- 14. Main working memory. Volatile – Information lost when you switch off the power.
- 15. Special type of memory chip that holds software that can be read not written to. Eg-: ROM-BIOS
- 16. On screen pictures are stored here. Located on a video card.
- 17. Memory is measured : bit, byte, KB, MB, GB, TB Bit : All digital computers work on a binary numbering system. Processed data in ones or zeros.This 1 or 0 level of storage is called a bit and the memory capacity is measured in multiplies of bits. 32-bit computer
- 18. 8 bits = 1 byte 1024 bits = 1 KB(Kilo Byte) 1024 KB = 1 MB(Mega Byte) 1024 MB = 1 GB(Giga Byte) 1024 GB = 1TB (Terra Byte)
- 24. Internal Hard Disks Capacity : Enormous. Often in excess of 40 Gigabytes Cost : Falling rapidly . Cheapest way of storing data External Hard Disks Capacity : Same as internal disks Cost : Expensive than internal disks
- 25. Zip Drivers Speed : Slower than normal hard disks but ideal for backups Capacity : 100 or 250 Megabytes Cost : Cost of the driver as well as the cost of each disk Jaz Drivers Speed : Very slow Capacity : Around 2 Gigabytes
- 26. Floppy Disks Speed : Very slow Capacity : Normally 1.44 Mbytes Cost : Very cheap CD-ROM Disks Speed : Slower than hard disks Capacity : Around 650-700 Mbytes Cost : Very cheap
- 27. DVD Drivers Speed : Much faster than CD-ROM drivers but not as fast as hard disks Capacity : Up to 17 Gbytes Cost : Slightly higher than CD-Rom drivers Formatting a disk You should be very careful about formatting a disk as any data on the disk will be lost after reformatting .
