1.Yes there is
ReplyDeleteThe system unit is a case that contains electronic components of computer used to process data while CPU interprets and carries out the basic instruction that operate a computer
2. Memory unit
The memory unit specifically the RAM stores your works in progress along with information ,such as what application you are using .if you run short of RAM ,you will experience serious computer slowdown
3.Difference between LCD and LED is that lcd uses florescent lights while led use light emitting diodes
4.Task manager enables you to monitor the application, processes and services currently running on your personal computer

Delete1.yes there is a different,between system unit and CPU. The system unit is a case that contains electronic components of the computer used to process data while the central processing unit(CPU) interpret and carries out the basic instruction that operate a computer.
Delete2.programs running : one of the most common reason for a slow computer are program running in the background.remove or on sable any ISRS and start up programs that automatically start each time the computer boots.
3.The fluorescent light in an LCD monitor are always behind the screen.on an LED monitor,the light emitting diodes can be placed either behind the screen or around its edges.the difference in lights and in lighting placement has generally meant that LED monitor can be thinner than LCDs.
4.Task manager enable you to monitor the applications,processes and services currently running on your PC. You can use task manager to start and stop programs and to stop processes,but in addition task manager will show you informative statistics about your computers performance and about your network.

ReplyDelete1.Yes there is a difference
The system unit is the power house of the computer because everything that a computer does is carried out here .In essence, without the system unit there will be nothing like a computer while the CPU is the place where the processing of data takes place.
2. The memory unit
The memory unit id a storage where data and instructions go when entered into the computer. The RAM specifically stores your works and information in progress .if your RAM is full ,you will experience computer slowdown
3. The difference between LED and LCD monitors is that LCD makes use of florescent lights while LED makes use of light emitting diodes.
4.Task manager enables you to monitor the applications, processes and services you are running currently on your computer. It can be used to start and stop programs
5.The logic NOR gate

ReplyDelete1. There is a difference ,the system unit is the first and most important hardware device. It is the power house of the computer while the CPU carries out all the basic instructions that operates a computer.
2.Memory unit
The RAM stores data and machine code currently being used.A full RAM will cause serious slowdown
3.The LCD makes use of flouresent lights which are behind the screen while the LED use light emitting diodes which are either at the edges or behind the screen
4.Task manager helps to show informative statistics about your computer performance and about your network
5.NOR gate

Delete1.Yes there is difference between the two.The system unit is a connection of electro-mechanical device that link together which is use to process data while the CPU is the part of a computer that interpreted and carries out instructions provided by the software.
2.The memory unit.A Ram constitute the internal memory of the CPU for storing data,programme and programmes.since access time is independent of the address to the word that is,each storage location inside the memory is as easy to teach as other location which takes the same amount of time. All these can slow the CPU.
3.LED,which stands for light emitting diodes differs from general LCD that is LCDS use fluorescent light while LED sea emitting diodes.
4.The task manager is a window that enables you to monitor the application process and services currently running in your personal computer. The task manager can be used to start and stop programmes and to stop processes.Also task manager can be used to show informative statistics about your computer performance and about your network.

ReplyDelete1.Yes there is a difference
*The main difference is that the cpu does not contain a power supply unit while a system unit provide supply to the computer.
*Also the cpu contains micro processor which processes data present on the mother board of the system unit while system unit processes and control the whole of the computer.
2 . Hard drive
If your computer did not read stored data, it would not need a hard drive .The computer retrieve bits of information from a disk that spin at thousands of revolution per second. The hard drive speed determine how long an application to access the data it need.
3 . The difference is that LED use those light emitting diode while LCD use fluorescent lights.
4 . The task manager enable the computer user to monitor the application, processes and services currently running on your PC. you can use it to start and stop processing. In addition it will show the informative active statistics about your computer performance.

1) the system unit is a case that contain electronic components of the computer used to process data.
CPU interpret and carries out the basic instructions that operates a computer.
2)if the CPU is slow or out of date,user may experience slowdown in modern applications or games. the part of the CPU that mostly cause this is hardware failure and it show it result in the PC performance. A maxed out CPU needs replacement or upgrade and could potentially overheat and fail which will cause the computer to breakdown or slowdown.
3)LCD is liquid crystal display. it uses fluorescent lights. the fluorescent lights in LCD TV are always behind the screen. they are thin screen, each has particular angle viewing and anti glare issue. The backlit TV provide better, clearer angle viewing than the edge lit LED tv.
LED lights s lights emitting diodes. it can be placed behind or around the screen. they are thinner than LCD . LED runs with greater energy efficiency and can provide a clearer, better pictures than LCD.
4)The task manager enables user to monitor the applications, processes and services currently running on user computer PC. it can be use to start and stop programs. it can also show user the informative statistics about user computer's performance and the networks.

ReplyDelete1)Yes there is, because the main difference between cpu is that the system unit and central processing unit (CPU) is that the CPU the system unit processes data and consist of a case which contains electronic component of your computer. The system unit of computer is available in different shapes and sizes. On the other hand CPU interpret and processes basic instruction which operates your computer. The job of the CPU is to impact overall computer power and to manage almost all operating of your computer.
2)software and hardware corruption are two reasons why your computer may slow down overtime. Two other huge Chloe it's are not having enough RAM(memory to run program) and simply running out of hard disk space. Not having enough RAM causes your hard drive to try to com pens ate for a lack of memory.
3) The fluorescent lights in an LCD TV are always behind the screen. On an LED TV ,the light emitting diodes can be placed either behind the screen or around it edges. The difference in light and in lightning placement has generally meant that LED TV can be thinner than LCDS,although this is starting to
change.
4) window task manager enables you to monitor the application processes and services currently running on your PC. You can use task manager to start and stop programs and to stop processes, but in informative statistic about your computer performance and about your network.

1.Yes there is a difference between system unit and CPU;system unit is a computer. It contains the heart of the computer and it is the external feature of the computer system that is commonly referred to as the brains of a computer and it is known as the processor and responsible for executing a sequence of stored instructions called a program
2. Memory unit
It's the part of the computer that stores information and data .if the memory unit is filled up there will be slowdown in the computer
3.The difference between LED and LCD ;
LED uses fluorescent light while LED use light emitting diodes.
