Restaurant management software helps businesses to provide a personalized customer experience to each customer.

What was the first computer with an operating system?

The first operating systems were nothing like modern operating systems and were usually called batch monitors, because all they did was automatically ran jobs sequentially in batch mode. Computers of the time had no interactive mode of operation. Computer companies did not supply software of any kind with their machines, so it was usually up to the user (company, university, government office) to write all their own software. The first batch monitor/operating system was done in 1954 by MIT for their UNIVAC 1103. General Motors did one in 1955 for their IBM 701.

The first computer to come from the manufacturer with an operating system already installed is a different question.

Why Memory is required in the system?

Is to read things on the computer or to hold a paticular document

Without RAM, a CPU can not execute any code at all, or access any data. The Operating System must be stored in RAM or the CPU can not access the code necessary to run the Operating System. Also, files that the user is working on must be stored in RAM or they are not accessible.

What is response time in operating system?

Response time measures the performance of an individual transaction or query. Response time is typically treated as the elapsed time from the moment that a user enters a command or activates a function until the time that the application indicates the command or function has completed. The response time for a typical Dynamic Server application includes the following sequence of actions. Each action requires a certain amount of time.

What is the best operating system for the PlayStation 3?

Popular features include: A start menu or application menu (Windows, Linux) Multiple desktop workspaces (Linux, Mac OS X) Taskbar (Windows, Linux) or dock (Mac OS X, also Linux) to track favorite program shortcuts and active applications A desktop environment. Linux has GNOME or KDE (and a few others), Mac has Aqua, and Windows Vista has Aero. Desktop acceleration (Mac OS X, Linux using Compiz or similar, and Windows Vista Premium, Business, or Ultimate)

What is a 64-bit operating system?

The primary difference, in non-technical terms, is that a 64-bit operating system is able to access more memory. A 32-bit operating system can only access up to 4 GB of RAM. Applications are steadily demanding more and more RAM. Even if you place more than 4 GB of RAM in your computer, you won't be able to use it with a 32-bit system. So to use the newest and greatest apps, you will eventually need a 64-bit operating system. A 64-bit operating system can access up to 16 exabytes (or 17.2 billion gigabytes) of RAM.

Which is a better operating system smartphone or android?

Android apps have already beaten Apple iOS quality wise and Sooner, around August android market is going to beat iOS again quantity wise. There would be around 4,25000 apps in android market. So, the thing is it is hard to tell what Android app is best. It basically depends on your on taste as every one has a different criteria of 'BEST APP'.

Usually people go for Professional or gaming apps. I am a android apps Addict and i have huge collection of Android apps. According to me The best professional app is Android Seven Pro which provides windows 7 interface look in your android based device whether its tablet PC or smartphone. If we talk about best android game apps than the fact is mostly people are in to hunting or shooting games like angry birds but you should simply go for Bird Hunting which is the best 2d hunting game and it is one of the most addictive app of android.

If you are not in to hunting games you just look for fun in apps than i would suggest you to try Air Flight Control. This apps is best available free line drawing fun. It is top ranked airplane game of Android.

i hope it works :)

BTW, for the first few steps when you start using your mobile, download and install some great apps will bring you more happiness. I like to enjoy time with audio content. I initially downloaded series of single APP such as BBC, Ted, etc. However, here I actually would like to push CastBox APP in front of you and you can easily get it freely from Google Play. It is a combinated serial podcast that includes diversified FM channels as a radio platform. I really enjoy a good bedtime before sleep and driving way back home with music. From my perspective, I rather recommend CastBox as a great Podcast installed on my phone.

What are the advantages of threads in Operating System?

In simple terms, they allow you to multitask better, meaning run multiple programs without experiencing a major decrease in performance.

What is a register in operating system?

A, special, high-speed storage area within the CPU. All data must be represented in a register before it can be processed. For example, if two numbers are to be multiplied, both numbers must be in registers, and the result is also placed in a register. (The register can contain the address of a memory location where data is stored rather than the actual data itself.)

The number of registers that a CPU has and the size of each (number of bits) help determine the power and speed of a CPU. For example a 32-bit CPU is one in which each register is 32 bits wide. Therefore, each CPU instruction can manipulate 32 bits of data.

Usually, the movement of data in and out of registers is completely transparent to users, and even to programmers. Only assembly language programs can manipulate registers. In high-level languages, the compiler is responsible for translating high-level operations into low-level operations that access registers.

What is difference between machine language and assembly language?

Machine language is the actual bits used to control the processor in the computer, usually viewed as a sequence of hexadecimal numbers (typically bytes). The processor reads these bits in from program memory, and the bits represent "instructions" as to what to do next.

Thus machine language provides a way of entering instructions into a computer (whether through switches, punched tape, or a binary file).

Assembly language is a more human readable view of machine language. Instead of representing the machine language as numbers, the instructions and registers are given names (typically abbreviated words, or mnemonics, eg ld means "load"). Unlike a high level language, assembler is very close to the machine language. The main abstractions (apart from the mnemonics) are the use of labels instead of fixed memory addresses, and comments.

An assembly language program (ie a text file) is translated to machine language by an assembler. A disassemblerperforms the reverse function (although the comments and the names of labels will have been discarded in the assembler process).

machine language faster than assembly language even than assembly language depend upon machine language

How spooling work in operating system?

Spooling usually involves saving temporary data to memory or hard drive. A common use of spooling is to format a print job in the computer before sending it to the printer. The print spool holds data until the printer is ready to accept it.

What are examples of computer software?
