Computer Architecture Questions
Can you be able to identify between Straight- through and Cross- over cable wiring?
Straight-through is type of wiring that is one to to one connection Cross- over is type of wiring which those wires are got switchedWe use Straight-through cable when we connect between NIC Adapter and Hub. Using Cross-over cable when connect between two NIC Adapters or sometime between two hubs.
What is cache memory?
Cache memory is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. As the microprocessor processes data, it looks first in the cache memory and if it finds the data there (from a previous reading of data), it does not have to do the more time-consuming reading of data from larger memory.(cache memory is used between the c.p.u and the ram to access dta fastly)
What is hard disk and what is its purpose?
Hard disk is the secondary storage device, which holds the data in bulk, and it holds the data on the magnetic medium of the disk.Hard disks have a hard platter that holds the magnetic medium, the magnetic medium can be easily erased and rewritten, and a typical desktop machine will have a hard disk with a capacity of between 10 and 40 gigabytes. Data is stored onto the disk in the form of files.
Where’s MBR located on the disk?
Master Boot Record is located in sector 0, track 0, head 0, cylinder 0 of the primary active partition.
What’s the speed and device maximum specs for Firewire?
IEEE 1394 (Firewire) supports the maximum of 63 connected devices with speeds up to 400 Mbps.
What’s the difference between L1 and L2 cache?
Level 1 cache is internal to the chip, L2 is external. L1 Cache is of Higher speed than that of L2 Cache.
Name the processor lines of two major manufacturers?
High-end: Intel - Pentium (II, III, 4), AMD - Athlon. Low-end: Intel - Celeron, AMD - Duron. 64-bit: Intel - Itanium 2, AMD - Opteron
Where does CPU Enhanced mode originate from?
Intel’s 80386 was the first 32-bit processor, and since the company had to backward-support the 8086. All the modern Intel-based processors run in the Enhanced mode, capable of switching between Real mode (just like the real 8086) and Protected mode, which is the current mode of operation.
Where does the Real mode on the CPU come from?
The original 8086, which only had 1 MB of memory. This megabyte is split into low memory for IRQ tables, application memory and high memory.
How do you clear CMOS password?
Since CMOS is a special chip with its own battery, the best way to clear out a CMOS chip is to disconnect it from its power supply.
What are the basic expansion card types?
ISA and PCI, ISA can be used only on XT, AT and ATX boards. The industry now considers ISA obsolete.
What is a compiler?
Compiler is used to translate the high-level language program into machine code at a time. It doesn.t require special instruction to store in a memory, it stores automatically. The Execution time is less compared to Interpreter.
What is NV-RAM?
Nonvolatile Read Write Memory, also called Flash memory. It is also know as shadow RAM.
What is called Scratch pad of computer?
Cache Memory is scratch pad of computer.
What is the difference between primary & secondary storage device?
In primary storage device the storage capacity is limited. It has a volatile memory. In secondary storage device the storage capacity is larger. It is a nonvolatile memory. Primary devices are: RAM / ROM. Secondary devices are: Floppy disc / Hard disk.
