Basic Computer Knowledge
Hi, Here I am going to share some basic computer knowledge with You
1. The maximum windows partition size of FAT-16 is 2GB.
2. 80386 (i386) was the first 32-bit processor introduced by the Intel in 1985.
3. We can create maximum 24 logical drives and extended partition can only have 23 logical drivers and we can assign the drive letters from D to Z (a, b and c are reserved for floppy, cd-drive or removable mass storage device and primary partition respectively). 4.The real mode on the CPU had come from The Original 8086, which only had 1MB of memory.
4. Cache Memory - Cache memory is a high speed memory kept in between processor and RAM to increase the data execution speed. When the processor needs to read from or write to a location in main memory, it first checks whether a copy of that data is in the cache. If so, the processor immediately reads from or writes to the cache, which is much faster than reading from
or writing to main memory. There are different levels of cache as follows :
1. L1(Level1) - is very first, fastest, quick, expensive and primary cache built in to the processor. It is very small 8KB to 64KB and uses the high-speed SRAM (Static RAM). The Intel Celeron processor uses two separate 16KB L1 caches, one for the instructions and one for the data.
2. L2(Level2) - is the next step down from L1 cache, larger and slightly slower than L1 cache and secondary cache. It is external. It is bigger than the primary cache (typically 64KB to 4MB).
3. L3(Level3) - L3 cache is not found nowadays as its function is replaced by L2 cache. L3 caches are found on the motherboard rather than the processor. It is kept between RAM and L2 cache.
5. The IEEE 1394 interface is a serial bus interface standard for high-speed communications and real-time data transfer used by computers as well as in digital audio, digital video, automotive and aeronautics applications. It supports the maximum of 63 connected devices with speeds up to 400 Mbps. It is also knows by the brand names of FireWire (Apple, in 1995), i.LINK (Sony), and Lynx (Texas Instruments).
6. MBR (Master Boot Record) is located in sector 0, track 0, head 0, cylinder 0 of the primary active partition.
7. TCP/IP (Transmission Control Protocol/Internet Protocol) is a protocol suite which helps the computer to communicate over intranet or internet. TCP is used to transmit data packets from one system to another either they are in same or different network, provides services like HTTP, FTP, SMTP, IMAP, POP3, etc. runs on the port no 17. Ip is Internet Protocol is used to identify the system on the network and provide communication.
8. A chip set is a group of integrated circuits (microchips) that can be used together to serve a single function and are therefore manufactured and sold as a unit. The most common chip set reference is the input/output controlchips of a motherboard . The chip set usually contains several controllers that govern how information travels between the processor and other components. The main difference between original & chip set motherboard is that in motherboard chipset, the chip like north bridge & south bridge are differ from motherboard manufracturer, but in original, the motherboard & chipset all are from same company manufracturer. e.g. INTEL original & intel chipset.
9. If we have latest motherboard, we can accommodate 6 hard disk drives.
10. Processor lines of two major manufacturers - High-end : Intel Pentium (II, III, 4), AMD - Athlon. Low-end : Intel - Celeron, AMD - Duron and 64-bit: Intel - Itanium 2, AMD - Opteron.
11. To clear CMOS Password, remove the battery and the jumper near by the CMOS battery for 5minutes and reinsert both in its place.
12. ISA - Integrated Standard Architecture, PCI - Peripheral Component Interface, PCI-eXP - Peripheral Component Interface Express, AGP - Accelerated Graphical Port, AMR - Audio Modem Raiser and CMR - communication & modem raiser are all the basic expansion card types.
