Computer Hardware

This is a true statement.

Its simple, if you look on back of computer tower near top there is a fan that is your power supply module. You need to remove the cover on the entire tower to gain access usually 4 to 8 screws and two plug and play type connecters, simply swap in the new one screw back in connect plug ins and your all done.

Well, there are 31472628.9 kb's in one megabyte. This means that in 20 mb's, there are 629452578 kb.

A device that forwards data packets from one local area network (LAN) or wide area network (WAN) to another. Based on routing tables and routing protocols, routers read the network address in each transmitted frame and make a decision on how to send it based on the most expedient route (traffic load, line costs, speed, bad lines, etc.). Routers work at layer 3 in the protocol stack, whereas bridges and switches work at the layer 2. Routers are used to segment LANs in order to balance traffic within workgroups and to filter traffic for security purposes and policy management. Routers are also used at the edge of the network to connect remote offices. Multiprotocol routers support several protocols such as IP, IPX, AppleTalk and DECnet. Routers can only route a message that is transmitted by a routable protocol such as IP or IPX. Messages in non-routable protocols, such as NetBIOS and LAT, cannot be routed, but they can be transferred from LAN to LAN via a bridge. Because routers have to inspect the network address in the protocol, they do more processing and add more overhead than a bridge or switch, which both work at the data link (MAC) layer. Most routers are specialized computers that are optimized for communications; however, router functions can also be implemented by adding routing software to a file server. For example, the NetWare operating system includes routing software that can route from one subnetwork to another if each one is connected to its own network adapter (NIC) in the server. The major router vendors are Cisco Systems and Nortel Networks. Within an enterprise, routers serve as an internet backbone interconnecting all networks. This architecture strings several routers together via a high-speed LAN topology such as Fast Ethernet or Gigabit Ethernet. Within the global Internet, routers do all the packet switching in the backbones. Another approach within an enterprise is the collapsed backbone, which uses a single router with a high-speed backplane to connect the subnets, making network management simpler and improving performance. In older Novell terminology, a router is a network-layer bridge. Routers also used to be called "gateways." For more understanding of how the network layer 3 works within the protocol stack, see TCP/IP abc's. See layer 3 switch, route server, router cluster and routing protocol.

The data path size of a current DIMM (Dual In-line Memory Module) typically varies based on the type and generation of the memory. For DDR (Double Data Rate) SDRAM, the data path size is commonly 64 bits for standard DIMMs used in most desktop and laptop computers. This means each DIMM can transfer 64 bits of data simultaneously, effectively doubling the data transfer rate with each clock cycle.

At Uncodemy, which offers the best data science course in Thane, Mumbai, Navi Mumbai, Delhi, Noida, and other locations across India, students learn about the importance of memory architecture in computer systems, including the role of DIMMs in enhancing performance. Additionally, specialized DIMMs, like DDR4 or DDR5, may support wider data paths in certain configurations, contributing to improved bandwidth for high-performance computing applications.

Small in size, Portable, easy in handling, no chances of bad sector ie durable as compared to hard disk!
Items can be moved on and off of them, unlike a CD, when you burn an item, it burns it and no items can be put back onto it. Plus, they are small and portable, unlike a CD. They also come in 16 gigabyte forms, with DVDs only going up to 4.7 gigabytes, and CDs going up to only 750 megabytes.

The CD has to be CD-RW to be able to delete whats on the disk and add something new.

run dxdiag.exe

it can be found in C:\Windows\System32

it is the ROM . The ROM has firmware which controls the booting up of the computer during start up. The booting software, known as BIOS (Basic Input Output System) give instructions to the POST (Power On Self-Test) which then runs tests to on the computer to make sure that all the devices are well connected to the computer. Sometimes this process is so fast that when observed, it appears as if there is are no tests being run by the POST process.

The name of the program that lets your computer to communicate with hardware devices is call KERNEL. Kernel communicates between hardware and software of a computer and manages how hardware resources are used to meet software requirements

A. By Using the Motherboard Jumper:

In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.

Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.

When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.

Make sure to turn the PC off before opening the cabinet and resetting the jumper.

B. By Using Software:

I have found that BIOS/CMOS Password Recovery Tool is the most effective.:

BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

The transmission speed of the cable is limited in most cases by the hardware attached to it.

Cat5 basic cable has been used successfully up to 1 gigabit speed using ethernet. There have been lab tests proving it might be useful for 10gigabit over short ranges but usually that requires Cat5e or Cat6 grade cable.

The most common speeds are 10/100 mb ethernet.

As far as I'm aware USB drives don't go up to 500GB; the closest you'll be able to get is to buy an external HDD, which will normally cost around £ 30-50 depending on make.

Two main input devices on a computer are:

Keyboard: A keyboard is a standard input device that allows users to input text, numbers, and commands into a computer. Keyboards usually have a standard layout of alphanumeric keys, function keys, navigation keys, and modifier keys that allow users to type quickly and efficiently.

Mouse: A mouse is another common input device that allows users to move a cursor or pointer on the screen and interact with graphical user interfaces (GUIs). A typical mouse has one or more buttons that can be used to select items on the screen, and a scroll wheel that can be used to navigate content.

Two main output devices on a computer are:

Monitor: A monitor is the primary output device on a computer, and it displays text, images, and video on the screen. Monitors come in different sizes and resolutions, and they can be CRT, LCD, or LED-based.

Printer: A printer is an output device that allows users to print text and images onto paper or other media. There are different types of printers, including inkjet, laser, and dot matrix printers, and they can be used for different applications such as printing documents, photos, or labels.

I use to be CCleaner ó Glary Utilities for the registry and to administrate start programs.

Sometimes with a blower I clean it inside.

And it's very importar uninstall all garbage programs we don't use.

The software needed to set up a WAN network include a router of some sort to have network connectivity. Additionally, software would be needed on every computer that would be connected to the WAN network.

Looks like most (if not all) micro SD memory modules need to be inserted into an SD adapter, and from there, into the SD slot. The adapter is the shape and size of a normal SD card, and should have come with the microSD card when purchased. Soon there may be devices that can use the card directly. If your device is enabled with one, the older SD slot is about the size (HxW) of a quarter looking at it from the side. Cheers.

A scanner copies pictures or text into the computer.

You do not need a dial-up modem. However, you will need to either purchase or rent a DSL modem, which works differently from a dial-up modem, and is usually outside the computer.

Pen drive is an Removable Device. It is use to File sharing. Easy to Read and Write files. Pen Drive is not consider as an Input/Output Device.

1 KB actually equals 1024 bytes, according to binary. See, there's a metric system, and a binary system. They're both so close in measurement, though, that they're usually used interchangeably.

There are 3 types of scanners currently being sold on the market. These scanners are photo scanners, paper fed scanners, and hand held scanners.
