How does TCP ensure reliable data transfer?

There are three features that allow TCP to reliably and accurately track the transmission of data from source to destination. They are flow control, session establishment, and numbering and sequencing.

What disk can store the most data?

Blu-ray disks can hold quite a bit of data on them, depending on how many layers, they can easily store anywhere between 20gB to 200gB worth of data. DVD's hold the next most, maxing out at around 4.7gB worth of data. CD's and data disks can roughly hold less than 1gB worth of data, usually around 700mB.

What does the performance of a hard drive affect?

The three most notable things that hard drive performance will effect is:

  1. The start up time of your computer. As the information need to run the OS must be transferred from the hard drive to the systems RAM.
  2. The start up time of programs.
  3. If you are using almost all of your RAM space the system will use your hard drive to store information normally keep in RAM. In this case your hard drive performance will effect your entire system, but more ram will correct this problem better then a faster hard drive.

How can I delete a file that won't delete?

Go to the YouTube video I am linking to below. Or search for "file won't delete" in the search there, more than one way to do it.

First of all, I've tried deleting it by dragging it to the recycling bin, which doesn't work. I've tried Shift+Del on it, and it doesn't work. I've even booted my computer in safe mode with command prompt and tried deleting it with the command prompt, and it doesn't work.

Every time I try deleting or even moving it, it just shows the load window, but doesn't have the bar moving... It stays like this.

I've tried leaving it on over night, and nothing is different.

I'm on Windows Vista. Help!

Why is cache memory more expensive than hard disk?

as the cache memory is mory faster than RAM or hard disk ,but the main reason is that the cache memory has comparator and storage medium at the same time, the comparator checks if the address of the value being accessed is in the associative memory(a part of cache)or not, and the ordinary memory(another part of cache)has the data....

Where can one get a Seagate Hard Drive?

What are the capacity of microcomputer?

Different microcomputers have different capacities in terms of processing speed and storage. For instance, the main memory of a tablet computer averages 128 MB to 1 GB while that of a desktop computer averages 1 GB to 8 GB.

What is the difference between 'sata' and 'ata' hard disk drives?

ATA = Advanced Technology Attachment and has speeds of up to 133 Mbps. Has a 40 pin connector. SATA = Serial ATA. Smaller connections and higher data speeds. See the attached link for a webpage with more info.
The SATA host adapter is integrated into almost all modern computers. The difference is sata is 7 pin connectoe and ata is 40-44 pin

Whats the best thing to use to backup software?

I use and recommend Handy Backup, it's easy and reliable backup software for home use.

What type of device is vpn adapter?

A virtual network adapter can also be used with a virtual private network (VPN), which is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or individual users with secure access to their organization's network.

How many logical drives can be created on a fat drive?

When you partition a hard drive into two or more partitions (storage areas) those extra drives are called logical drives. So you can have 2 or 3 or more logical drives on one physical hard drive. It varies.

What is a hard drive disc?

The Hard drive or disk, is the actual system you are using. In my case it is Windows 7 Ultimate. On most computers it will be be your D drive, and should never be tampered with, unless you are qualified to do so, as you can cause severe or terminal damage to your system. It is sometimes refered to as your Motherboard.

When setting up a computer what is the first thing you should install?

Software Word 2007 ,but intranet will already be installed if you get the type of comp. that offers that software.

Is USB 2.0 or Firewire faster?

The maximum speed of USB2 at 480M/Sec is a little quicker than Firewire 400 (IEEE.1394a) which runs at 400 M/Sec (hence the "400" bit of the name). In tests, however, FireWire 400 delivers a higher sustained transfer speed. Benchmarks suggest that hard drives connected with FireWire will copy information considerably faster than they would using USB 2.0. To achieve higher performance, FireWire requires additional circuitry in supported devices. This often makes FireWire more expensive than USB 2.0. Firewire 800 (IEEE.1394b) as the names suggests, has a peak speed of almost 800 M/Sec. Used primarily by PC musicians for recording and transferring multichannel audio at high sample rates and for digital video cameras and decks

Why is a hard disk inside the system unit sometimes called a fixed disk?

Floppy drives and CD/DVD roms are examples of removable disks because the storage medium is removed from the drive. A hard drive has a set of magnetic platters that you do not remove, making it a fixed disk.

How can a computer ensure the safety of data stored in a computer system?

The biggest thing is backups. Using a RAID 1 configuration helps in cases of hardware failure, since if one hard drive fails, you have the other one and can rebuild the set from it with very little downtime. However, unlike backups, RAID 1 (another other RAID configurations) does not protect against data corruption from viruses and deliberate sabotage. Nor does RAID 1 help you if the computer is physically stolen. You can replace the computer, but you cannot replace what is on it as easily a lot of times.

There also needs to be malware solutions. Antivirus utilities are one such help. Safe computing policies and proper Internet settings also help.

Another point is security practices and solutions. Not only do you need protection from data corruption, but also against how the data is used. You don't need your emails getting leaked to your competitors or some group who wants to put you out of business. Nor do you want your computers and network being misused for criminal activities. So you must use the right security and firewall settings, and also secure your networks and relays from being used by those who have no business using them. If espionage is expected, then you have to screen and monitor your employees, and not provide any means for spying (for example, disable external media like USB drives). Sometimes setting the computer to only read outside media is good enough, then nobody can copy it out. But then you run into the possibility of malicious software getting installed, perhaps snooping software, enabling a bad employee to access the company's data from elsewhere.

What are three ways to improve hard disk performance?

Three ways to improve the hard disk performance of your computer include defragmenting, removing duplicate files and by compressing or encrypting folders. These methods help to create hard disk space, thus making your computer run faster.

Where can you find informantion about your hard disk recovery?

Typically any software application you use for hard disk recovery will provide a comprehensive report when the recovery has been completed. If you are having any issues with a particular application, contact their customer support for detailed information on how to obtain and read the generated report.
