Maskable interrupts trigger events are not always important and so the programmer can decide that the event should not cause a program to jump. Nonmaskable interrupts can not be ignored by the programmer and therefore they have absolute priority.

Automatic Private Internet Protocol Addressing (APIPA) is a common alternative to the use of the Dynamic Host Configuration Protocol (DHCP) to request and retrieve an Internet Protocol (IP) address for a host. APIPA simplifies the assignment of IP address and subnet-mask configuration information to hosts in small networks. When APIPA is used, the operating system allows the assignment of a unique IP address to each station on a small local area network (LAN). This avoids the administrative overhead of running a DHCP server or manually setting IP configuration information.

Yes, there is, creative's Sound Blaster X-FI Go uses a USB port to connect to a laptop or desktop to have high fidelity sound using the sound card.

It provides more instructions than RISC (Reduced Instruction Set Computer).

Pretty much every company would use that os if it has to deal in finance.

Depends on the specs

If a hard drive is constantly spinning, there is likely too many background programs running. Remove or restrict the programs to slow down the hard drive.

You will need to plug the SD into your PC; either using a card adaptor or, for most modern PCs and laptops have SD sockets built-in. Next use Windows explorer to navigate to your pictures. Select the ones you want to move (hold down the Ctrl key and click each one you want to move). If you want to move them - ie remove them from the PC and put them onto the SD card, type Ctrl+X to cut the images, navigate to the SD card, and type Ctrl+V to paste them into position. If you want to copy the images, then do the same as the last paragraph, but type Ctrl+C instead of Ctrl+X.

Some do some dont. If theres nothing been plugged into it for awhile, is it warm? If its warm, that means it must be using -some- electricity (albeit maybe just a tiny bit)

If it is the cabling within your system tower (or more commonly CPU), then I would suggest using sleeves since internal computer cabling usually needs rewiring with almost every change in the hardware or fault conditions. A heat shrink would severely limit this. At the same time, the air gun you would use to shrink could even damage the components near the cables if done improperly.

buy a pc thats how

In the 8085, DMA (Direct Memory Access) is controlled with HOLD and HLDA. The HOLD signal is a request to release the bus. The HLDA signal is the 8085's acknowledgement of that request. HLDA means that the 8085 will release the bus in one half clock cycle, i.e. at the end of T3. The 8085 will remain in that hold state until HOLD is released, at which point it will take control of the buses again.

The HOLD'ing device has complete control and can access any memory or I/O. Often, the 8237 DMA controller is used to provide sequencing of the operation.

The 8237 DMA controller interfaces between up to four peripheral devices and the 8085. It provides an address register for each device so that the device does not need to do so. The device only needs to indicate that a byte of data is available, or is required, and the 8237 will take care of storing or fetching the byte.

Yes it is.

It could mean any number of things, depending on context. Most commonly, it is simply used to indicate that an item is black in color.

I am quite impressed with the DELL application of it. I have a DELL XPS Studio that is about 1.5 years old. ZERO troubles anywhere. I have 12 GB RAM and a 2 Terabyte Internal Hard Drive. Zero Problems to date!

An output device is a device which is used to view data given out by a computer, be it a printer, monitor or speaker.

The Intel i5-3330 is going to give you better performance. Although the speed of the i3 processor is higher, the i5 is designed with higher performance capabilities.

1TB is 240 bytes. It follows that a 40 bit address bus can address 1TB. Since 1TB is 1TB regardless of the system's word size, a 40 bit address bus can address 1TB on a computer with an 8 bit, a 16 bit, a 32 bit, or any other word size.

Many times an electronics circuits can not fit into one printed circuit board (PCB) either due to electrical or mechanical or other system design constraints or considerations. In such cases, there is many times one PCB is fixed on top of another board generally through mating connectors or a flex. circuit/cable. In such cases, the smaller board placed on a main board (mother board) is called a daughter board. In same sense all the boards plugged in the computer motherboard sockets are daugher boards. - Neeraj Sharma

In order to do it you have use either two network cards (wireless + LAN, or two LANs, or two wireless cards) or you can use software such as WMWare to create a virtual PC (using setting you can get one more and even more ip addresses for only one existing in real life computer).

A Cat5 cable contains 4 pairs of 2 wires twisted together, making a total of 8 individual wires, however only 2 wire pairs (4 wires) are actually used for communication.
