MS-DOS is an operating system designed for the IBM PC by Microsoft in 1981. MS DOS is Microsoft Disk Operating System. It was a command-line interface, meaning the user had to type in commands to use it, unlike Windows which is a Graphical User Interface. MS DOS was released on IBM PCs when they came out in the 1980s and continued in popular use until the mid 1990s, by which time the first of the Windows operating systems, Windows 95, began to take over.

MS DOS commands were either stored as individual programs, known as external commands, or in a file called Command.com, which stored more commonly used commands. These were called internal commands. Included in these would have been commands like COPY, DEL, DIR, CD and RD.

COPY enabled the copying of files.

DEL deleted files.

DIR gave a listing of files in a directory (now called a folder).

CD changed from one directory to another.

RD removed a directory.

It all depends on the computer, if you mean the actual operating system, it varies a whole lot. If you mean the CPU itself and the components, pretty much everything is removable, usually the power supply cannot be removed from a computer case. Hope this helps!

Unfortunately, the icons can not be made bigger on the Blackberry Curve. However, the font can be changed by going into the settings and choosing keyboard.

Computers and electronic devices contain a lot of different materials. Some take a long time to degrade naturally (such as metals), others take a very long time to degrade (such as plastics). Most problematic, however, are rare earth metals and heavy metals such as lithium, traces of mercury and similar substances, which can be poisonous when leaking into soil and ground water.

That's called a back-up.

This is an digital device that can respond to messages sent from many similar devices. For example, computers in a network.

Well a disadvantage I know of is, it takes forever to get into bursaries, like you have to go through tons of tests and lot of interviews. And if you don't pass all your courses you might lose your bursary.

The USB Data Transfer Device is a data transfer device that may remind you of a tape measure with the way the USB cables pull from the box. Two USB cables extend from the box and allow you to connect two different computers. You connect one USB to a computer and the other USB to another. Each cable has the ability to extend up to 4 feet in length which gives you a little more than 8 feet of a distance between both computers.

When you connect two computers with the USB Data Transfer Device, they are recognized as additional drives. This allows you to easily transfer data from one computer to another. The good news is that you are not limited with space issues on a thumb drive or wasting CDs to move data. Data can be moved just by moving over from one folder to another. The good news is that you can transfer large amounts of data from 25 MB per second.

The USB Data Transfer Device is powered through the USB ports on the computers. It doesn't require an AC outlet power connection. There is a blue LED indicator light to help you know when your data transfer is complete. This is the most convenient way to transfer data between two computers.

Icons are used to access files and programs on the computer.

Its primary function is to prevent accesses from untrusted (or undesired) external systems to internal systems and services, and to prevent internal users and systems to access external untrusted or undesired systems and services.

More generally, its purpose is to implement security and performance policies.

As an example, you can prevent external systems to access internal servers, as well as to prevent users to use P2P software or access social networks, for performance and security reasons.

First off, you have to be able to tell the customer about technical things in plain English that they can understand. Examples are a good way. You have to have good people skills and can communicate with the customers.

Computer addiction needs treatment just like any other addiction. Finding a new hobby, realizing why you spend so much time on the computer, and scheduling your time on the computer are all ways to work on your addiction in the meantime.

they can be reused

NIC (Network Interface Cards), cables, routers, switches, hubs. Optional stuff can include storage area network (SAN), network attached storage (NAS), firewalls, and IDS (intrusion detection systems).

Not really. They arent magnetic. But on some laptops, especially newer ones, the laptop sreen is held closed by magnets so to replace the conventional locking hinge and its slot on the computer so no damage occures on the hinge while also giving it an attractive look.

Actually, if it has speakers they are most certainly magnets and the hard drive also has very strong magnets in it (unless is an SSD). Any electric motor also has magnets and is an electromagnet under power.
