2. Daftar dan jelaskan secara singkat
tiga jenis spyware.
Spyware perangkat lunak tipuan yang diam-diam diinstal pada komputer melalui web.
Setelah spyware diinstal pada hard disk Anda, memungkinkan orang luar untuk panen
informasi rahasia, seperti penekanan tombol, password, atau alamat email Anda.
a.
Adware, or pop-up
generators, is a kind of spyware that tracks web surfing or online
buying so that marketers can send you targeted and unsolicited pop-up and other
ads.
Adware,
atau generator pop-up, adalah sejenis spyware yang
melacak berselancarnya web atau membeli secara online sehingga pemasar dapat
menargetkan pengiriman dan tidak diminta pop-up dan iklan lainnya.
b.
browser
hijackers, which change
settings in your browser without your knowledge, often changing your browser’s
home page and
replacing it with another web page, and search hijackers, which intercept
your legitimate search requests made to real search engines and return
results from phony search services designed to send you to sites they
run.

3. Definisikan
secara singkat booting
Booting is the process of loading an operating
system into a computer’s main memory. Without booting, computers could not
operate. The programs responsible for booting are stored permanently in the
computer’s electronic circuitry. When you turn on the machine, programs called diagnostic
routines test the main memory, the
central processing unit, and other parts of the system to make sure they are
running properly. Next, BIOS (basic input/output system) programs are copied to
main memory and help the computer interpret keyboard characters or transmit
characters to the display screen or to a diskette. Then the boot program
obtains the operating system, usually from the hard disk, and loads it into the
computer’s main memory, where it remains until you turn the
computer off.
computer off.
Booting
adalah
proses loading sistem operasi ke dalam memori utama komputer. Tanpa booting,
komputer tidak bisa beroperasi. Program yang bertanggung jawab untuk booting
disimpan secara permanen di sirkuit elektronik komputer. Ketika Anda
menghidupkan mesin, program yang disebut diagnostik rutinitas menguji memori
utama, unit pengolahan pusat, dan bagian lain dari sistem untuk memastikan
mereka berjalan dengan baik. Selanjutnya, BIOS (sistem input / output dasar)
program akan disalin ke memori utama dan membantu komputer menginterpretasikan
karakter keyboard atau mengirimkan karakter ke layar atau ke disket. Kemudian
program boot memperoleh sistem operasi, biasanya dari hard disk, dan beban itu
ke dalam memori utama komputer, dimana masih sampai Anda mengubah komputer off.
4. Apa
saja kegunaan dari surge protector, regulator tegangan, dan UPS, dan mengapa
perangkat ini penting?
SURGE PROTECTOR, A
surge protector, or surge suppressor, is a device
that protects a computer from being damaged by surges (spikes)
of high voltage. The computer is plugged into the surge protector,
which in turn is plugged into a standard electrical outlet.

SURGE
PROTECTOR, sebuah pelindung lonjakan arus, atau penekan
surge, adalah perangkat
yang melindungi komputer agar tidak rusak oleh lonjakan (spike)
tegangan tinggi. komputer dicolokkan ke surge protector,
yang pada gilirannya dicolokkan ke stopkontak listrik standar.

yang pada gilirannya dicolokkan ke stopkontak listrik standar.
Use a surge protector to
protect against too much electricity: Plug all your hardware
into a surge protector (suppressor), which will prevent damage to your
equipment if
there is a power surge. (You’ll know you’ve experienced
a power surge when the lights in the room suddenly get
very bright.) Surge protectors cost $10–$35.

VOLTAGE REGULATOR A
voltage regulator, or line
conditioner, is
a device that protects a computer from being damaged by insufficient power—“brownouts” or “sags” in voltage. Brownouts can occur when a large machine such as a power tool starts up and causes the lights in your house to dim. They also may occur on very hot summer days when the power company has to lower the voltage in an area because too many people are running their air conditioners all at once.

VOLTAGE REGULATOR, regulator tegangan, atau garis
conditioner, adalah perangkat yang melindungi komputer dari kerusakan oleh
cukup kekuatan-"brownouts" atau "sags" di tegangan.
Brownouts dapat terjadi ketika mesin besar seperti alat listrik dijalankan dan
menyebabkan lampu di rumah Anda untuk meredupkan. Mereka juga dapat terjadi
pada hari-hari musim panas yang sangat panas ketika perusahaan listrik harus
menurunkan tegangan di suatu daerah karena terlalu banyak orang yang
menjalankan AC mereka sekaligus.
UPS A UPS (uninterruptible power supply) is
a battery-operated device that
provides a computer with electricity if there is a power failure. The UPS will
keep a computer going for 5–30 minutes or more. It goes into operation as
soon as the power to your computer fails.
provides a computer with electricity if there is a power failure. The UPS will
keep a computer going for 5–30 minutes or more. It goes into operation as
soon as the power to your computer fails.
Consider using a UPS to
protect against complete
absence of electricity: Consider plugging your computer
into a UPS, or uninterruptible power supply (available at
electronics stores for $35–$200). The UPS is kind of a
short-term battery that, when the power fails, will keep
your computer running long enough (5–30 minutes) for
you to save your data before you turn off the machine. It
also acts as a surge protector.

5. Jelaskan
Sistem Biner ?
binary system is a
two-state system used for data representation in computers; has only two
digits—0 and 1. Why it’s important: In
the computer, 0 can be represented by electrical current being off and 1 by the
current being on. All data and program instructions that go into the computer
are represented in terms of these binary numbers.
Sistem Biner adalah Dua langkah sistem yang
digunakan untuk representasi data di komputer; memiliki hanya dua angka 0 dan
1. Pada komputer, 0 dapat diwakili oleh listrik
malakukan saat off dan oleh arus berada di 1. Semua data dan instruksi program yang masuk ke komputer hal ini yang diwakili dalam angka biner.
