Theoretically, a nanobyte would be 10 ^(-9) byte (one billionth of a byte). However, a byte consists of 8 bits and a bit cannot be divided, so the minimum we could get is one eighth of a byte. So a nanobyte doesn't really exist.
An IDE cable connects a hard drive or CD drive to the main board of the computer.
What is a computer that controls access to hardware and software on a network?
It would be a host. All other computers connected to that network are clients.
How to connect 2 monitors to a laptop?
Most laptop computers have a jack somewhere that will allow a standard computer monitor cable to be connected. Sometimes they are hidden behind panels that flip up, slide, or otherwise can be opened. If you have the manual, it will give the exact location of the jack, as well as describing the resolution and color selections possible.
The physical material on which the computer stores data?
If by material you mean chemical element, then silicon is the material. Its a group IV metal on the periodic table and is a semiconductor. It is also the second most abundant material on earth, with roughly 25 percent of the earths crust being some sort of silicon compound, (oxides and such)
Semiconductors' electrical resistance can be controlled by adding impurities from group III and group V elements from the periodic table. This allows precise control of electrical characteristics from which useful devices such as the Transistor (electrical switch) can be made from.
Switches can either be ON or OFF. This is represented in the computer world as 1 or 0. By combining these electrical switches useful information can be stored in terms of 1s and 0s. A 1 or 0 is called a Bit; a string of eight 1s or 0s is called a byte.

The basic input/output system (BIOS) on a computer is a simple yet important program on a personal computer (PC) that helps the computer properly boot and run an operating system (OS) during startup. BIOS drivers are typically used in reference to the program itself, and how the program runs and interacts with other devices on the computer. The BIOS drivers on a computer are saved on a small battery located on the motherboard and allow for the proper initialization and startup of a computer when powered on.
What are the disadvantages of standalone computers?
A standalone computer is not able to share resources electronically and is also harder to attack (must be done physically). So if you don't need to share information with anyone and are concerned about electronic attack, use a standalone computer.
Hardware components that convey information to people?
Output Device is a type of hardware component that conveys information to one or more people.
Visual Display Unit (VDU) = Monitor
Printer.
Sound output, speakers.
Why is data bus bidirectional but address bus unidirectional?
The address bus is unidirectional becos address information is always given by microprocessor to i/o devices. The data bus is bidirectional bcos it takes the data from other devices & also give the data to other i/o devices
Which type of input device would you choose if you were going to play a shoot 'em up'computer game?
I would use a joy stick if i had to. But i think that it would be cool because it would be a lot easier.
What network topologies are most commonly used on today's networks?
star topology. Because they include a centralized connection point; can easily be moved, isolated, or interconnected with other networks; they are, therefore, scalable. For this reason, and because of their fault tolerance, the star topology has become the most popular layout used in contemporary LANs.
What is the difference between intel845 865 915 and 945 chipset motherboards?
== == The Intel® 915G Express chipset, designed for the Intel® Pentium® 4 processor supporting Hyper-Threading Technology† in the LGA775 package, delivers a decade's worth of innovation:
PCI Express* buses can deliver over 3.5 times more bandwidth for I/O and graphics cards than PCI and AGP 8X respectively1.
Graphics flexibility, with support for the built-in Intel® Graphics Media Accelerator (GMA) 900 and for PCI Express graphics cards
Flexible memory support for dual channel DDR2 533 memory and dua-channel DDR memory
The Intel® 865G chipset, designed for the Intel® Pentium® D processor (compatible with the lead free version of Intel® 865G Chipsets supporting socket LGA775) and the Intel® Pentium® 4 processor supporting Hyper-Threading Technology†, is a highly flexible and scalable solution that meets a broad range of demanding computing needs. The 865G chipset offers solid performance through a variety of exciting features, including dual-channel DDR 400 main memory, an 800 MHz system bus, and an integrated graphics controller with Intel® Extreme Graphics 2 technology.
The temperature inside the case should not exceed degrees C?
This will generally depends on the components of your computer and what it's tolerances are. Some cases will commonly get to 100+ degrees F inside and others are layered with fans and such to keep the temp down.
As a rule, don't let it go much over 100 degrees F. If it's that hot in the air, it's reaching bad temps on your motherboard and various components.
What combinations of hardware and software offer slow or fast data speeds?
What general combinations of hardware and software offer very slow or fast transmission speeds?
The time it takes to send, receive, copy, move and save files (data) from one storage media to another varies depending on the devices and the communication method being used. For example hard drive to floppy disk very slow (saving files to a floppy disk can be 10 times slower than saving to a hard drive), hard disk to CD slow, hard disk to hard disk (direct link) very fast, hard disk to flash memory fast, network server to hard drive using a LAN can be very fast but is dependant upon network traffic how many users are accessing the network at the same time, Internet to hard drive using the WAN via modem by email or from a website speed here depends upon the type of connection you have dial up slow or broadband fast and whether you are uploading or downloading and the amount of traffic. Size of file being sent will also affect this.
What is the Function of the CPU in plc?
1_ Updating the inputs and outputs.
2_ Perform logic and arithmetic operations.
3_ Communication with the memory.
4_ Scanning application programs.
5_ Communicating with a programming terminal.
What kind of data does cache memory store?
I believe that the cache memory stores certain copied information that you go to most often from the hard drive. So, the unit checks the cache memory first before it checks the whole hard drive. That way you can find the location of a certain file faster in the smaller (cache) memory versus finding it in the bigger hard drive where it takes longer to find that same file.
Can you use CDs on the Eee PC?
Not by default. You need to plug an external USB CD-ROM drive in if you want to play CDs.
Machine vision has been characterized by a lack of standards, which has resulted in the necessity for expensive customization of systems. Today's objective is to investigate the development of a vision system which utilizes or establishes standards.

Where are the instructions stored needed to start the computer?
All the instructions to start computer are stored in BIOS (Basic Input Output System ) at ROM. Whenever computer is started BIOS checks presence and status of RAM and input & output devices like keyboard, monitor, printer, disk drives etc. After checking these devices BIOS searches operating system in different drives. On finding operating system BIOS startups the operating system and hands over control of computer to operating system.
What are the differences between a power cable a signal cable and a data cable?
Power cable is a thick cable connecting your computer to an electrical wall outlet. It can also be a thin wire connecting your modem or other device to a rectangular [ usually ] power supply to your electrical power bar or wall outlet.
Data cables are much thinner, used mainly internally, and can be many wires attached together horizontally to form a wide ribbon of wires. However, a data cable can also be a much thicker cable connecting your modem, router, printer etc. to your computer.
What are the advantages of a computer input system?
with the help of input devices we get output.
Steps:
instruction given(data in)-->process(in processing data in cpu)--> output derived
the output can only be derived when input proccessor is supported by input devices or drivers.
Why PC technician do not repair a power supply?
PC technicians avoid repairing power supplies because the units usually contain specific components that would allow the computer to operate even if the components are still faulty. It becomes better to buy a new one to avoid further damage to the whole system.
