What are the differences between Windows ME and Windows 7?
Windows 7 is several full generations newer, and is based on completely different internal programming architecture.
Windows ME is built upon version 4, which began with Windows 95. Windows ME was the end of this product line and was abandoned for a new generation of operating systems, built upon Windows NT. This includes Windows 2000 and XP, which were both based upon version 5 of the core system.
Windows Vista was once again a break from the past, being re-architectured for speed and the new advancements in technology available at the day. For example, Windows Vista used new display engines to leverage the power of Graphics Processing Units. Windows Vista began version 6 of the core OS.
Windows 7 is built upon this, and is version 6.1.
As far as differences go, the system can be used in much the same way, and requires basically no 'learning' to begin using the system. However, because of the underlying changes, most software that was created for Windows 95-ME will not work in Windows 2000, XP, Vista, or 7. Any software created in the past 10 years or so should work fine.

Windows ME and 2000, for example were like seasonal fashion outfits out. Their value was very limited before its use was dismissed.
What is the difference between the storage medium used within a SATA harddrive and a SSD harddrive?
Both devices provide non-volatile storage, which means they’re capable of storing data even when a computer loses power (as opposed to something like random access memory, which requires a constant source of electricity).
Hard disk drives (HDDs) use mechanical components to store data using magnets, while solid-state drives (SSDs) store data electronically. SSDs do not contain moving parts, which is advantageous for several reasons.
To understand the benefits of each technology, we need to understand how they function. It’s fascinating stuff, but skip over this next section if you simply want to review the advantages and disadvantages of each.
How Hard Drives WorkHard drives contain one or more platters, which are discs coated with a thin layer of magnetic material. As the platters spin, the head stack assembly—similar in appearance to a turntable stylus—reads and writes data as north or south magnetic charges. These charges appear to the computer as 0’s and 1’s (a system known as binary data). Each binary digit is called a bit.
Modern hard drives can store an incredible amount of data. A 1-terabyte hard drive contains 8 trillion bits. That’s a lot of zeros, and it means the surface of a hard drive’s platters are densely packed with information.
The hard drive’s read/write heads never actually touch the magnetic material; they float on a cushion of air generated by the spin of the platters. That cushion of air is incredibly small, about 5 to 10 nanometers. To put that in perspective, a human hair is about 90,000 nanometers in diameter.
If something goes wrong, the heads could come into contact with the platters, scraping off the magnetic material and physically removing data from the hard drive. That’s called a head crash, and it’s one of the most common sources of data loss. That’s where phrases like “my computer crashed" came from.
Modern hard drives have plenty of safeguards to prevent this type of catastrophic failure. Still, because they use moving parts, every hard drive eventually fails—the spindle that moves the platters could seize, the heads could become misaligned, or the circuit board that relays data to the rest of the computer could stop working.
HDD read/write speeds are also limited by the speed of their spindles. Typical computer hard drives spin at 7,200 rotations per minute or faster, but even so, to read a certain bit, the heads must physically move over that space on the platter.
How Solid-State Drives WorkAs their name implies, solid-state drives don’t rely on moving components to store data. They consist of NAND flash memory, which uses floating gate transistors to store data with electricity.
If that sounds complicated...well, it is, but the basic function is fairly simple. Basically, the floating gates register as a “0" when they hold an electric charge and as a “1" when they don’t hold a charge. The gates are organized into smaller pages and larger blocks.
Here’s the main drawback of the technology: SSDs can’t really modify data easily. To change a file, the drive needs to make a copy of an entire block, erase the first block, then rewrite it with the new data. Erasing a block of data requires a relatively large amount of voltage, so overwriting data is a complex process, and floating gates become less reliable as they’re overwritten multiple times.
What does that mean for your data? Eventually, your SSD will become slower, and data corruption will become more common. Modern SSDs have technology to limit this effect, but that’s outside the scope of this answer—the important point to keep in mind is that every type of long-term data storage device will eventually fail, so while solid-state drives are more reliable than traditional hard drives in some respects, they’re not perfect.
Should you use a hard drive or a solid-state drive?Both storage technologies have benefits. Depending on how you use your computer, you might prefer one type of storage.
Here are some of the advantages of each option:
- Hard drives are (currently) larger and less expensive. At the time we wrote this, SSDs cost about twice as much as hard drives on a per-gigabyte basis. For the average computer user, HDDs also offer more capacity. If you’re storing a ton of files and you’ve got a limited budget, you’ll probably want a hard drive. That might change over time. The per-gigabyte price of solid-state drives has dropped in recent years and should continue to drop as more consumers adopt the technology.
- Solid-state drives are less susceptible to physical damage. Because they don’t have moving components, solid-state drives are often a better choice for laptops and external storage. Of course, other computer components are still susceptible to physical damage, so don’t take this as an excuse to throw your devices around.
- Solid-state drives are much faster. A typical SSD can read data at around 550 megabytes per second (MBps) and write at 520 MBps. A hard drive might achieve speeds of around 125 MBps. If you’re concerned with performance (for instance, if you’re building a gaming PC), a solid-state drive offers huge speed advantages.
- Solid-state drives generally use less power than hard drives. When spinning up, a hard drive can use as many as 25 watts. While writing data, most SSDs use fewer than 2 watts. That’s important if your device relies on battery power. If you’re buying a drive for a laptop and you’re concerned about battery life, an SSD might offer a significant advantage (but be sure to check the SSD’s wattage consumption before making your purchase).
- When you delete data from a solid-state drive, it’s probably gone for good. When you delete data on a hard drive, the device doesn’t overwrite your files right away; it simply marks the space occupied by the files as available, then writes over that part of the platter later. Because of how they read and write data, solid-state drives clear out the space almost immediately. In other words, if you delete a file from a hard drive using conventional methods, it will be recoverable for some time. That’s not true of SSDs. This isn’t a major concern for most computer users, but it’s an important point to keep in mind if you regularly work with sensitive data.
Regardless of which storage device you choose, you should make sure you have a decent backup plan in place. Never trust a single device with all of your important data, and try to keep some free space on your HDD or SSD to allow it to function as efficiently as possible. If your computer seems much slower than normal, or if you hear sounds coming from a hard drive, back up important files immediately and replace your storage media.
While neither technology is perfect, they’re both capable of storing incredible amounts of information, and they’re both reliable options when used properly.
What is the Quality differences in micro cassettes?
A mini cassette was used in transcriber machines. It is a bit longer in length than the micro cassette, but the same height. The reason I know this is because I have transcribed from both sides for doctor's office, beginning back in the 1990s. The mini was never used for very long. Kind of like the beta and the VHS tapes for video recording. VHS won out over beta.
volatile memory is memory that will wipe all the data saved to it after the computer shuts down e.g: RAM.
Difference between dimensional modeling and ER modeling?
E-R modelling basically deals with Entities and their relationships to capture the overall process of the system. While Dimensional model/Muti-Dimensional Modelling deals with Dimensions (point of analysis) for decision making and not to capture the process.
What is the difference between record management and information management?
A main difference is that records management is associated with governance, risk, and compliance. Information management is the collection and management of information from one or more sources and the distribution of it to various audiences.
What is the difference between HP Pavilion and HP Compaq desk top computers?
HP and Compaq were both independent computer sellers until 2001 when they merged. Computers are still made under both names, the leading lines being HP's Pavilion and Compaq's Presario. The differences between the different lines tend to be mostly cosmetic, although the difference between individual models can be substantial.
It is also noted that Compaq computers tend to be made with lesser-quality parts, making the costs more inexpensive, affordable and economic than the HP computers.
2 dimm 2gb RAM comes with 2 1gb modules.
4 dimm 2gb RAM comes with 4 512mb modules.
What is difference between TPN Mccb and 4P Mccb?
Basically tpn means the tripple pole + nutral protectin mbc .
What is the difference between uart and usart?
UART is universal asynchronous receiver/transmitter. It is a piece of computer hardware that translates data between parallel and serial forms. Modern ICs that have UART's that can also communicate synchronously are called USARTs (universal synchronous/asynchronous receiver/transmitter).
What is the difference between casio fx 991es plus and casio fx 991es calculator?
The Casio FX-82ZA Plus is a replacement for the Casio FX-82ES+ which was developed in collaboration with the South African Educators for the South African syllabus. The FX-82ZA model appears to have all the features of the FX-82ES.
What are the differences between Windows and Linux access control lists?
In Windows, files have an owner (usually the creator), but not a group, to which they 'belong'. - and the owner isn't really important in determining access rights. Files either have an explicit list of people and groups or inherit it from a parent directory. These lists specify individual users and groups (in a list) who have access to the directory/file/subdirectories, and the specific rights granted to each item.
In Unix/Linux, each file and directory belongs to a specific user AND group - for example, configuration files may belong to user root and a group set up for administrators (typically called 'wheel'). Instead of having a list of people who can/cannot access the file, you simply specify read, write and execute privileges for the owner and group the file belongs to, and then anyone else.
In Windows, if you have a configuration file, the owner doesn't matter. Instead you set the ACL to include any Administrators you want to access the file, as well as any other users that may need to read it, including the program it configures.
In Linux, you'd perhaps set the same configuration file to belong to the root user, and the group to which the configured program runs in, and everyone to no rights at all - so only root and the program can read it. Or you could set the owner to the user the program runs under and the group that the Administrators belong to, so the program can read it and so that Administrators et.al. can change the file, but keep everyone set to no rights to keep the configuration secure.
They are two different ways of accomplishing security, each with their own configuration peculiarities and performance issues.
Difference between ado and ado.net?
ADO is a com base library that supports only connected data. This means that when we access the data (view, edit and update) it is affected in real-time,since the connection is being used all the time. ADO uses the objects as reference data known as Recordset object. Hence it basically gives a single table view of the data. We can also join tables to create a new set of records in ADO.ADO allows to create only client-side cursors. Using ADO we can persist records in XML format and XML integration is not possible.
ADO.NET is a CLR based library that supports disconnected recordsets. This means that When we access data, ADO.NET makes a copy of the data using XML and holds the connection to pull down the data or to make any requested updates as long as we need. The best method to follow is ADO.NET.ADO.NET uses various objects known as Dataset that allow to access data in various methods. Hence it allows to store the relational model of the database and helps us to access /update the data in each related table individually. ADO.NET supports both client-side and server-side cursors. Also the cursors are handled as classes in ADO.NET providing a way to create efficient applications. Using ADO.NET we can manupulate records in XML format. Also ADO.NET 2.0 provides Multiple Active ResultSets (MARS) which allows to have two datareader on one connection open at sametime.
What is the difference between a harddisc and RAM?
RAM is temporary memory, while hard disk space is more permanent memory.
When you save a file, you save it to your hard disk, but when you call up the interet, it uses temporary memory, RAM. The more windows you have open, the more RAM you will use up. Proccesses that the computer preform take up RAM, while saved files and programs take up hard disk space.
Hard disk space is usually a whole lot larger than RAM. For instance, a laptop may have 250GB (gigabytes) of hard disk space, and only 2GB of RAM
AnswerRAM is the computers memory, where as hard disk is the storage of the memory.information stored in RAM can be accessed and utilized much faster than information stored on a hard drive. The RAM is therefore generally used to store information in the short-term, for example for programs and processes you are currently running that will need a certain bit of information very quickly in order to function. The hard drive is generally for more long-term storage and for files which are required to run programs. When you run a program many files required for function may then be copied to RAM for use while running this

Cats are felines while mice are rodents. Cats are carnivorous while mice are omnivorous.
What is the difference between a computer and a machine?
The Main difference between a computer and a machine that computer is an intelligent device which has the ability to decide by its own through processing different data analysis while machine is least intelligent and is always waiting for user. For Example, a loader or a drill machine can never work without its Operator While Computer is always acting by its own through following instructions, like Supervisory Control and Data Acquisition (SCADA) System which is always getting data from the remote sites and shaped it in proper information.
What is the Difference between pipeline processing and serial processing?
* The main difference is that pipeline processing is a category of techniques that provide simultaneous, or parallel, processing within the computer and serial processing is sequential processing by two or more processing units.
What is the difference between an industrial pc and a home pc?
A home computer is used for a multitude of items, which include internet, computer games, home-movie creators, and basically is an all-around computer. A business computer is specialized in one solitary and sole task for the company, and is extremely well in that area, that it is very poor in other areas because the computer was not designed for other areas.
Are tools sold at Home Depot of a lesser quality than those bought at a reputable tool supply shop?
Not if you match the model #'s, but some stores will sell older models (which they buy cheap from dewalt) at current prices. There are minor differences (i.e. the plastic grip design, torque, hammer ability, quality of battery and home/professional usage.) it's best to check dewalt.com to see current models.
What are the similarities and differences between a system call and a procedure call?
System Call is a method used by a process to request action by the operating system. A function is a subroutine and mostly part of a user program which may or may not return a value to the calling function.
Difference between mouse and track ball?
They both do the same job. And on an older mouse it's easy to see the similarities. An older computer mouse would have a ball underneath. Then as you moved the mouse around the ball would roll and the computer would count the rotations. A track ball was basically a mouse turned upside down. Instead of moving the mouse to rotate the ball, you'd move the ball directly with your fingers instead.
What is the difference between 8 bit and 16 bit ina computer?
the number of bits describing the architecture of a CPU system define its maximum "word size", or how many bits it can process at one time. In an 8-bit system, a standard integer can hold a value of up to +127, and an unsigned integer can hold a value up to +255. In a 16-bit system, unsigned integers can hold values up to 2^16 - 1, or 65,535.
When speaking of 8-bit and 16-bit color, for 8-bit color you can either mean the palette size (256 colors, each of which can be assigned any color) where only 256 unique colors can be used at a time. The other meaning of 8-bit color is a different 256-color system (called 8-bit truecolor) where you define the color by attributing 3 bits to red, 3 to green, and 2 to blue. This system is less effective than the 8-bit palette system.
16-bit color (also called high-color or 16-bit truecolor) allows a total of 65,536 unique colors to be displayed, anywhere on screen at any time, by assigning 5 bits to the red and blue channels, and 6 bits to the green channel (our eyes are more sensitive to green).
What'a the difference between 4 cell and 6 cell laptop batteries?
well, generally, the more cells a battery contains, the more capacity a battery has. the batteries have different working hours because of the number of the cell. what's more every cell has a "3.7 V normal volt" and the maximum volt is 4.2V, the Volt of a battery finally depends on the number of the cells and the series circuit/parallel circuit. i
What is the difference between isp and broadband?
ISDN stands for Integrated Services Digital Network, and Broadband ISDN is written as B-ISDN or BISDN. ISDN involves digital transmission over telephone copper wire and other media. B-ISDN involves the transmission of data over fiber optic and radio media.
What is the difference between DBMS and file management?
When a computer user wants to store data electronically they must do so by placing data in files. Files are stored in specific locations on the hard disk (directories). The user can create new files to place data in, delete a file that contains data, rename the file, etc -- all known as file management; a function provided by the Operating System (OS).
If the user wishes to perform some operation on the data he has placed in the file, such as viewing a list of his friends that celebrate their birthday in June, he has to scroll through all the data by himself in order to see the data he is interested in. Moreover, he has to know where he put the files that contain the data, and if there are multiple files he has to remember to go through each one of them.
A Database Management System is intended to remove this burden of manually locating data, and having to scroll through it by allowing the user to create a logical structure for the data beforehand, and then allowing the user to place the data in the database that the DBMS is managing. In this way the DBMS abstracts away the physical concerns of organising files, and provides the user with a logical view of the data.
Note, that the DBMS will still -- behind the scenes though -- place the data in files on the hard-disk.
Database is multiuser and provides utilization of resources whereas in file management there is no utilization of resources.
